Game engines look cheap until a revenue threshold, a royalty or a console fee appears.
This guide ranks fifteen of them on what the first ninety days cost in learning time, which plan limits bite when a game ships, whether the source stays yours, and how far you depend on one owner.
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
In short
What game engines software does
Game engines supply the rendering, physics, input and export code that games run on, plus the editor or framework where developers assemble scenes, logic and assets for publishing.
The ranking follows five checks. Setup effort comes first, then real cost, then the route for getting data out, then lock-in, then the intended buyer. The ranking then gives places 1 to 3 to challengers outside the best-known brands, if the category has such vendors, and the incumbents follow. We explain on how we work why the tests are these five and why no product receives a score.
MIT-licensed engine run by a foundation, with no fees at all
Ranked #1 of 15 in Best Game Engines in 2026.
Free tierOpen sourcePublished pricingElsewhere
Nothing about Godot has to be bought, which changes the first ninety days: the cost is learning time and the work of arranging console access through a publisher. The licence is MIT, stated in the repository, so you can keep and modify the source indefinitely.
XR support is built in for OpenXR and WebXR. No country is given for the foundation, and its funding is sponsor tiers rather than customers, so help is community-shaped.
What stands out
MIT licence
Open source
Foundation-run
Where it costs you
Console releases depend on third-party publishers, so the engine alone does not get you onto those platforms.
The project is funded by donations and sponsor tiers, which means no purchasing relationship exists to point to if priorities change.
Right for
Teams wanting a zero-cost engine with a permissive licence and broad export
Wrong for
Studios that must ship on consoles without involving a publisher
Not stated by the vendorFree download, no plans, no royalties
Engine funded by a foundation, with a long publishing platform list
Ranked #2 of 15 in Best Game Engines in 2026.
Free tierPublished pricingElsewhere
The strongest line on the site is the platform list, which reaches web portals such as Poki and Facebook besides the consoles. There is no price list because there is nothing to price.
The foundation behind it appears in the footer copyright, yet no country or address appears on the homepage. Expect to verify console access and licence terms yourself before committing a production schedule.
What stands out
No royalties
Source available
Console targets
Where it costs you
The homepage never names the licence, so forking rights are unconfirmed until you read the linked licence page.
The foundation's country is not stated, which leaves the contracting party unclear for any formal procurement.
Right for
Small teams shipping one codebase to web portals, phones and several consoles
Wrong for
Buyers whose procurement requires a named legal entity and licence up front
Not stated by the vendorFree forever, no licensing cost or runtime fee
No-code engine whose cloud projects and AI credits scale by plan
Ranked #3 of 15 in Best Game Engines in 2026.
Free tierPublished pricingElsewhere
GDevelop is built around plan limits rather than engine features. Free allows three cloud projects; Pro removes that ceiling and adds collaboration and version history. Yearly billing saves up to 40 percent and cancellation is allowed at any time, with no trial period named.
Listed integrations include the Apple App Store, Google Play, Steam, AdMob, Stripe and PayPal. The page gives iOS limits of 15 and 30 per month without saying which plan owns which.
What stands out
Free plan
No-code
Publishing caps
Where it costs you
The paid plans show no amounts in the page text read, so the cost of a team has to be confirmed before budgeting.
Publishing and cloud-project caps rise by plan, so a busy team can hit the Free limits within a week.
Right for
Beginners and small teams building without code who want mobile and Steam publishing
Wrong for
Teams that need uncapped publishing without paying for a higher plan
Not stated by the vendorFree plan plus Silver, Gold and Pro, monthly or yearly
Hosted engine with app hosting included and seat-based business plans
Ranked #4 of 15 in Best Game Engines in 2026.
Free tierPublished pricingEurope
Storage separates the three plans more than features do: one, ten and fifty gigabytes. A one-month minimum term makes it cheap to test, and yearly invoicing is arranged by emailing sales for organisation plans of a year or more.
A trial of the personal or organisation plan runs through an upgrade code from the same address. The pages do not name a currency code, so check that before invoicing.
What stands out
Free plan
Per-seat plans
App hosting
Where it costs you
Projects on the free plan are public, so private work needs a paid plan from the first day.
Organisation pricing is per seat, so the bill grows with every extra team member.
Right for
Small studios wanting hosting bundled in and a monthly plan they can cancel
Wrong for
Anyone needing private projects without paying for a plan
United KingdomFree plan; personal and per-seat organisation plans, billed monthly
Version 4.4, announced in October 2026, rewrites the renderer for Vulkan and Direct3D 12, adds a new shader compiler, a CLI tool and Native AOT.
That is a lot of change in a single release, so budget time for migration if you are on an older version. The footer credits the .NET Foundation and contributors. No plans exist to compare.
What stands out
MIT licence
C# scripting
Open source
Where it costs you
Scripting is in C# only in the text I saw, which narrows the hiring pool to .NET developers.
Funding comes from donations, and the pages state no country or contracting entity.
Right for
Developers already working in .NET who want editor tooling and source access
Wrong for
Teams whose scripters work in other languages than C#
Not stated by the vendorFree; no prices or plans published
Framework owned by a non-profit foundation, with donation funding
Ranked #6 of 15 in Best Game Engines in 2026.
Free tierOpen sourcePublished pricingElsewhere
MonoGame calls itself a framework, so expect to spend the first ninety days assembling your own workflow rather than opening an editor. In return nothing recurs on the invoice. The foundation is a non-profit, and the site gives no country for it. Check which parts sit outside the Microsoft Public License before redistributing the source.
What stands out
Microsoft Public License
Open source
Console targets
Where it costs you
Console access requires authorisation, so reaching those targets is not self-service.
Some portions of the code sit outside the main licence, which a legal review would need to separate out.
Right for
Programmers wanting a code framework with many mobile and console targets
Wrong for
Designers who expect a visual editor and ready-made tools
Not stated by the vendorFree; no subscription, royalties or runtime fees
Fully open source engine with a named lead and zero fees
Ranked #7 of 15 in Best Game Engines in 2026.
Free tierOpen sourcePublished pricingElsewhere
The platform list includes tvOS and Android TV, which several larger engines on this page do not name. The pitch is that developers never pay to use the engine, and the MIT licence supports that claim in writing.
The lineage is stated plainly: the lead came from Corona Labs. There is no commercial tier, so help comes from the community, and no country is given for the LLC.
What stands out
MIT licence
Open source
Mobile and desktop
Where it costs you
Development is led by one named person, so continuity depends on a small group.
The contact entity is an LLC whose country is not stated, so procurement has little to check.
Right for
Solo developers shipping to phones, TV boxes and desktop with a permissive licence
Wrong for
Companies that need a vendor contract or service commitments
Not stated by the vendorFree; no hidden fees, charges or royalties
Source-visible engine with a quarterly royalty above a threshold
Ranked #8 of 15 in Best Game Engines in 2026.
Free tierPublished pricingEurope
Flax is the only engine on this page whose commercial terms are a royalty with a stated threshold, which helps a small game and costs a successful one.
The licensing page also offers per-seat or flat-fee deals with pricing by team size, so a large studio can negotiate away the royalty. The footer says it is made in Poland. Reading the EULA before building is advisable.
What stands out
Royalty model
Source on GitHub
Custom licences
Where it costs you
A 4 percent royalty applies once quarterly earnings pass the threshold, so a hit game changes the cost.
The legal name of the company is not in the text I saw, which weakens due diligence.
Right for
Studios wanting source access to a 3D engine and willing to pay a share
Wrong for
Developers who want a licence with no revenue sharing at any scale
PolandFree for non-commercial use; royalty on commercial release
Modular Gems architecture under two permissive licences, run by a foundation
Ranked #9 of 15 in Best Game Engines in 2026.
Free tierOpen sourcePublished pricingElsewhere
The Gem system is the main design choice: you add only the modules you need, and the catalogue is listed on the site. Having two licence files means checking which applies to the part you reuse.
The release naming (26.05) shows a dated cadence. As a pure game choice it is broader than most: robotics is a named target, so simulation work reuses the same tooling.
What stands out
Apache-2.0 and MIT
Open source
Robotics via ROS
Where it costs you
The foundation's legal entity is not named on the homepage, so it is unclear who stands behind it.
Its scope extends to robotics and metaverse work, which may pull focus away from a pure game project.
Right for
Teams that want a modular engine and may later need ROS-based simulation
Wrong for
Small teams after a narrow engine with a single obvious workflow
Not stated by the vendorFree; donations accepted, no plans
Community-maintained Apache 2.0 library for desktop, Android, iOS and web
Ranked #10 of 15 in Best Game Engines in 2026.
Free tierOpen sourcePublished pricingElsewhere
The facts on the homepage are short: the licence, the community maintenance and the platform list. Because the page describes the Patreon link without calling it a requirement, nothing is payable.
That leaves the whole risk with the team: you choose your tools, your update schedule and your answers to bugs, with no commercial party to escalate to.
What stands out
Apache 2.0
Open source
Community-maintained
Where it costs you
Maintenance sits with a community, so no vendor is committed to fixes or dates.
The page gives no owner or country, leaving nobody to hold to a service level.
Right for
Programmers who want an Apache-licensed base covering desktop, phones and the web
Wrong for
Teams needing a supplier, support contract or a finished editor
Not stated by the vendorFree; Apache 2.0, with a Patreon link
Small zlib-licensed engine, free for commercial work with no limits
Ranked #11 of 15 in Best Game Engines in 2026.
Free tierOpen sourcePublished pricingElsewhere
Commercial use without limits is stated outright, which is as close to a guarantee as a licence page gets.
The weakness is administrative: the homepage gives no company, address or country, only informal contacts, so a purchasing department has nothing to file. For a one-person project that does not matter. For an agency invoice it does.
What stands out
zlib/libpng licence
Open source
No organisation
Where it costs you
Nobody is named as owner, so there is no entity to contract with.
Contacts are a social account and a nickname, which does not satisfy a supplier review.
Right for
Hobbyists and small teams wanting a permissive licence and a very small engine
Wrong for
Companies whose supplier checks require a named legal entity
Not stated by the vendorFree; costs nothing, commercial use allowed
Yearly plans that unlock publishing targets one tier at a time
Ranked #12 of 15 in Best Game Engines in 2026.
Free tierPublished pricingElsewhere
The ladder is easy to read: web only, then desktop, then mobile. Refunds are available within 30 days if no game has been published, a narrow condition that disappears once you publish.
Students and teachers get a Studio discount. The copyright line names Stencyl, LLC and says it is made in California and Japan, but no country is stated plainly. Schools may only evaluate the Starter plan.
What stands out
Free plan
Yearly billing
Tiered publishing
Where it costs you
Mobile publishing, ads and in-app purchases sit on the top paid plan, so the cheapest mobile route costs the most.
Only annual subscriptions are listed, which removes a month-to-month exit.
Right for
Hobbyists and educators moving from a free tier to desktop and mobile releases
Wrong for
Anyone who wants monthly billing or free commercial publishing
Not stated by the vendorFree Starter plan; Indie and Studio billed yearly, no royalties
Three editions from a hobby start to console export
Ranked #13 of 15 in Best Game Engines in 2026.
Published pricingElsewhere
Console release is held back for the Enterprise edition, which means the cheapest path to Xbox Series X|S, PlayStation 5 or Switch is also the one with no visible price.
The homepage lists Windows, Mac, Linux, Android, iOS and HTML5 as well. No trial of the paid editions is mentioned. Expect a sales conversation before you can plan a budget past the free edition.
What stands out
Free edition
Three editions
Owned by Opera
Where it costs you
Costs could not be read: the homepage lists no amounts and /en/pricing returned 404.
It is part of Opera, so a buyer takes on a parent group's decisions.
Right for
Solo developers who start on a free edition and may later need console export
Wrong for
Buyers who need independent ownership and a visible price list
Not stated by the vendorEditions named Free, Professional and Enterprise; amounts not shown
Revenue-banded plans from a free tier up to custom contracts
Ranked #14 of 15 in Best Game Engines in 2026.
Free tierPublished pricingElsewhere
Eligibility is tied to money raised or earned, not to team size, so a funded start-up can need Pro earlier than a larger bootstrapped one. AI credits rise by tier, at 1,000, 2,000 and 3,000 a month, and the AI tools carry a 14-day trial.
California law governs terms for US users; elsewhere Hong Kong, Singapore or New York law applies. The pricing page shows no free plan or trial for Pro.
What stands out
Revenue thresholds
Free tier
Quoted tiers
Where it costs you
Crossing the revenue or funding threshold forces a move to a paid tier, so growth changes the bill.
Enterprise and Industry are custom-priced, with minimum commitments possible, so cost is only known after a sales call.
Right for
Studios that value a well-defined revenue ladder and can pay when they grow
Wrong for
Teams that want costs unaffected by revenue or funding
Not stated by the vendorFree Personal tier; Pro per month or year; Enterprise and Industry by sales
2D and 3D engine whose pages show no prices or entity
Ranked #15 of 15 in Best Game Engines in 2026.
Open sourcePricing on requestElsewhere
Most of what is verifiable here sits on GitHub rather than on the vendor site: the MIT licence is there, while cocos.com names none. The marketing pages say little beyond lightweight and cross-platform.
The footer copyright reads SUD, with telecom and ICP filing numbers but no company name, so ownership cannot be confirmed. This is the thinnest listing in the ranking and is placed last for that reason.
What stands out
MIT licence
Open source
No pricing shown
Where it costs you
No legal entity name or address is given, only filing numbers, so the supplier cannot be identified from the site.
No platform list or price appears in the text I saw.
Right for
Developers happy to judge the engine from its repository, not vendor pages
Wrong for
Buyers who need a stated owner, price or platform list
Not stated by the vendorNo prices or plans in the text I saw
Game engines supply the rendering, physics, input and export code that games run on, plus the editor or framework where developers assemble scenes, logic and assets for publishing. Rather than compare features, settle the following points one after another.
01
Start with pricing transparency
Prices are public at 14 products (Godot, Defold, GDevelop, PlayCanvas, Stride, MonoGame, Solar2D, Flax Engine, O3DE, libGDX, LÖVE, Stencyl, GameMaker, Unity) and on request at the remaining 1, so budget time for quotes if your favourite is in that second group.
02
Look at where the vendor sits
Check the vendor's home market (Elsewhere 13, Europe 2), because that is where subpoenas and data requests arrive first, whatever region holds your files.
03
Check the open source options
Source code is available for Godot, Stride, MonoGame, Solar2D, O3DE, libGDX, LÖVE, Cocos. Running it yourself swaps the licence fee for your own upkeep.
Game engines and money: thresholds, royalties and none at all
The headline price of an engine rarely decides the bill. Godot, Defold, Solar2D and MonoGame all state that they charge no royalty or runtime fee, so cost stays at zero however a game sells. Flax Engine is free for non-commercial use, then takes 4 percent once a quarter's earnings pass 250,000 dollars.
Unity ties its plans to revenue or funding: Personal under 200,000 dollars, Pro above that, Enterprise above 25 million. Stencyl charges yearly and promises no royalties. GameMaker shows no prices on its homepage at all. Write down your likely revenue for the launch year and for a hit, then check each engine's terms against both. A threshold that costs nothing today can change the economics the quarter a game succeeds.
Ask whether any charge depends on revenue, funding or downloads
Find the exact threshold and the period it is measured over
Check whether prices appear on the page or only after a sales call
Where the game can ship: web, phones and consoles
Platform lists look similar until you read the footnotes. Defold lists Xbox, both PlayStations, Switch, Steam, Poki and Facebook. MonoGame lists PlayStation, Xbox One and Switch but says console access requires authorisation. Godot supports desktop, mobile and web, and sends console releases through third-party publishers.
GameMaker puts console release in its Enterprise edition. Stencyl holds iOS and Android back for the Studio plan, and GDevelop caps desktop and Google Play publishing per day on lower plans. Solar2D adds tvOS and Android TV. List the platforms you must hit in the first year, mark which need a separate agreement, and ask each vendor who handles console certification.
List the launch platforms and mark every console
Ask which publishing routes need a separate agreement or developer enrolment
Check daily or monthly publishing caps on the plan you would buy
Foundations, companies and nobody: who stands behind the engine
Ownership decides what happens when a bug blocks a release. Godot is hosted by the Godot Foundation, Defold by the Defold Foundation, MonoGame by a non-profit foundation and Stride by the .NET Foundation with Open Collective funding. PlayCanvas is a registered English company, GameMaker belongs to Opera, and Unity contracts through Unity Technologies SF.
LÖVE names no organisation, libGDX is maintained by its community, and Cocos shows only filing numbers and a copyright line. Foundations give continuity but rarely a contract. Companies give a contract but can change terms. For each shortlisted engine, find who you would write to and whether any page names a legal entity.
Find the legal entity or foundation named in the terms or footer
Ask who handles a blocking bug and under what commitment
Check whether the licence file is on the vendor site or only on GitHub
Plan limits that bite: GDevelop, PlayCanvas and Stencyl
Hosted and subscription engines hide their cost in caps. GDevelop's entry tier stops at three cloud projects and a four-player lobby, while Pro removes the project cap and adds collaboration. PlayCanvas separates its plans by storage: one, ten and fifty gigabytes, and keeps free-plan projects public.
Stencyl's Starter plan adds a splash screen and web-only publishing, so a finished game needs Indie or Studio before it can leave the browser. These limits are fine for a prototype and awkward for a release. Count your projects, collaborators, builds per week and asset size, then price the plan that covers them rather than the one on the landing page.
Count cloud projects, collaborators and builds per week
Check whether projects on the entry plan are public or branded
Find the refund or cancellation terms before the first publish
What goes wrong most often when buying game engines software
Choosing an engine on its free tier and finding out at release that a revenue or funding threshold applies.
Assuming a console is a checkbox, when Godot, MonoGame and GameMaker each route consoles through authorisation, a publisher or the top edition.
Treating a GitHub licence as the vendor's terms, as with Cocos, where the cocos.com pages name no licence.
Skipping the supplier check on community projects such as LÖVE and libGDX, then needing a named entity for a client or a grant.

What is the best game engines in 2026?
Our ranking of 15 puts Godot first. Godot is a free download under MIT terms, and the site mentions no fees, royalties or charges.
The Godot Foundation hosts it, funded by donors and corporate sponsors in tiered levels, so there is no licence to buy and no vendor contract to sign. Desktop, mobile and web are covered directly; consoles run through third-party publishers, an extra step outside the engine.
Which game engines tools publish their pricing?
14 out of 15 state a price model on their own site:
Godot: Free download, no plans, no royalties.
Defold: Free forever, no licensing cost or runtime fee.
GDevelop: Free plan plus Silver, Gold and Pro, monthly or yearly.
PlayCanvas: Free plan; personal and per-seat organisation plans, billed monthly.
Stride: Free; no prices or plans published.
MonoGame: Free; no subscription, royalties or runtime fees.
Solar2D: Free; no hidden fees, charges or royalties.
Flax Engine: Free for non-commercial use; royalty on commercial release.
O3DE: Free; donations accepted, no plans.
libGDX: Free; Apache 2.0, with a Patreon link.
LÖVE: Free; costs nothing, commercial use allowed.
Stencyl: Free Starter plan; Indie and Studio billed yearly, no royalties.
GameMaker: Editions named Free, Professional and Enterprise; amounts not shown.
Unity: Free Personal tier; Pro per month or year; Enterprise and Industry by sales.
Everything else on the list is priced on request.
Is there a free game engines tool?
Godot, Defold, GDevelop, PlayCanvas, Stride, MonoGame, Solar2D, Flax Engine, O3DE, libGDX, LÖVE, Stencyl, Unity offer a free tier or a free self-hosted edition.
The next in line are Defold, aimed at small teams shipping one codebase to web portals, phones and several consoles, and GDevelop, aimed at Beginners and small teams building without code who want mobile and Steam publishing.
Who should not buy Godot?
Studios that must ship on consoles without involving a publisher. Console releases depend on third-party publishers, so the engine alone does not get you onto those platforms..
