Teams look for a Labelbox alternative when the credit meter, the account tiers or the company's direction stops matching the work. Some want a tool they can run on their own servers, some want a price per seat instead of per consumption unit, and some want a vendor that supplies annotators as well. The options below cover all three.
Sebastiaan SmitsFounderShort answer: Prodigy, Supervisely and Kili Technology head the list of Labelbox alternatives drawn from our data labeling software ranking. Ranking order favours the challenger over the household name, so the best-known vendors begin at place 4 where the category allows it. Prodigy is the one to try if you would rather pay once than watch a monthly unit count. Each of the 11 alternatives sits in Best Data Labeling Software in 2026 and is described against Labelbox.
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.
Labelbox bills in Labelbox units, and its limits page shows the free tier at 500 a month and Starter at a fixed 0.10 dollars per unit. Catalog, Annotate and Model each consume units on their own table, so a budget needs the consumption tables read before the first project, not after the first invoice.
The free tier tops out at 10,000 imported ground-truth annotations, 50 projects and 3 project tags. Single sign-on is described in the docs as an add-on for Enterprise customers, so a team that needs its identity provider on a small plan has to move to a sales conversation.
The Labelbox home page now leads with environments for frontier labs and a managed-agents product called Recursion, while labeling sits under a separate Horizon documentation set. Buyers who want a plain annotation tool may prefer a supplier whose whole product is that tool.

CVAT started inside Intel and is now run by CVAT.ai Corporation with offices in Delaware and Cyprus. The MIT-licensed Community edition runs on your own servers. The hosted Free plan stops at three tasks and 1 GB and exports annotations only. Single sign-on there needs a yearly plan.

Roboflow puts annotation at the front of a vision pipeline, so Label Assist and Smart Polygon draw on the same credit balance as training and hosting. The free tier gives 10 credits a month. Review mode and labeling analytics need Enterprise, and private projects allow model training until an admin opts out.
Switch from Labelbox if you label images only to train and deploy a vision model in one place.

SuperAnnotate AI, Inc. gives every tier its editor for images, video, text and audio. Starter, Pro and Enterprise differ in Orchestrate compute of 1K, 2.5K or 10K hours, in sign-on, and in support: a success manager from Pro, a solutions engineer on Enterprise. The pricing page prints no amounts.
Switch from Labelbox if you need a multimodal editor and are ready to request a quote.

Toloka AI BV, headquartered in Amsterdam, describes an agent that turns a written goal into a collection and annotation pipeline. Human review sits beside automatic LLM quality checks. Workers come from its own expert, generalist and crowd tiers. Its pricing address returned an error when we read it, and engagements begin with a demo.
Switch from Labelbox if you want a Dutch-headquartered workforce instead of running annotators yourself.

Sama is Samasource Impact Sourcing, Inc., with offices across North America, Europe and East Africa. It sells expert-led annotation, validation and model evaluation for vision, multimodal and sensor data as a delivered service. Its pricing address gave a not-found page, and the home page directs you to a call with an expert.
Switch from Labelbox if you want finished labels delivered, with validation, instead of a tool to operate.

Appen Limited was founded in Sydney in 1996 and is listed on the ASX as APX. It cites 1M+ contributors and 235+ languages, and acquired Figure Eight in 2018. The pages we read show no plan, price or self-serve route, so work is scoped by sales, which suits language-heavy projects.
Switch from Labelbox if your project needs many languages and a large contributor pool.

Scale AI, Inc. sells expert-labelled data rather than seats. Its Data Engine page covers text, image, video and 3D sensor-fusion annotation, plus RLHF, red teaming and evaluation. The pricing address is a form for booking an intro call, and the pages read show no self-serve path for teams with their own annotators.
Switch from Labelbox if you are buying RLHF or evaluation data from experts at lab scale.
Why Scale AI is #12 among 12 data labeling software products →
Prodigy: It is a lifetime licence with a year of upgrades, runs offline and is scripted in Python.

Supervisely: Community is free for two members and 5 GB, and Pro prices labeling-only seats below full ones.

Labelbox stays sensible when one platform should hold the data catalog, the annotation queues and model work together, and when a published per-unit rate of 0.10 dollars suits how you buy. Its limits page lists API rates of up to 20,000 requests a minute on Enterprise and 10 million data rows, so large imports are planned for. If your budget is steady and units are already understood, leaving costs more than staying.
Labelbox organises labels under ontologies of up to 4,000 features, with its own export schema. Pull a full export while the account is still active, because over the free-tier cap you can export but not add. Then map each ontology feature to the target tool's label set and test a sample.
Queues, review stages and custom metadata fields are set inside Labelbox, and the Starter plan allows 100 metadata fields. List them before you leave and rebuild the review steps by hand. Plan a short parallel run so annotators finish open batches where they started them.
The limits page lists 500 Labelbox units free each month and a Starter plan at a fixed 0.10 dollars per unit. Enterprise has no limit listed and goes through sales. What each action consumes depends on the product, so estimate with the docs table.
CVAT's MIT-licensed Community edition and Label Studio's Apache-2.0 Community edition can both be self-hosted. Prodigy runs offline on your machines under a lifetime licence. Supervisely and Kili list self-hosting too, with Kili restricting it to Enterprise.
Prodigy is sold from Berlin, Supervisely from Tallinn, Kili Technology from Paris and Toloka from Amsterdam. CVAT lists an EU office in Cyprus beside its US one. The others on this page name the United States or Australia.
CVAT's hosted Free plan has three tasks and 1 GB, Supervisely Community covers two members and 5 GB, and Roboflow gives 10 credits a month. Label Studio's Community edition and CVAT's are free to self-host.
Toloka, Sama, Appen and Scale AI sell labeling work through scoped engagements. None of the pages we read print a rate card, so expect a demo or intro call before you see a price.
On Labelbox it is an Enterprise add-on. CVAT needs a yearly plan, Prodigy includes OpenID Connect with the company licence, Label Studio keeps SAML and LDAP in Enterprise, and Kili limits it to its top contract.
