Teams look beyond DebugBear when they cannot read its costs before talking to someone, when they want the test runner inside their own pipeline, or when a speed check is only one part of a wider monitoring job. The routes lead to smaller hosted monitors, open source toolkits you run yourself, or broader platforms with uptime attached.
Short answer: Request Metrics, Speedvitals and PageVitals head the list of DebugBear alternatives drawn from our website speed testing tool ranking. Challengers take places 1 to 3 here. Big brands follow in the order of our category ranking. Request Metrics is the one to try if you want a plan list you can read and one small tool for lab and field data. All 11 alternatives below are ranked products from Best Website Speed Testing Tools in 2026, and each says where it differs from DebugBear.
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.
Pricing: Navigation leads to a trial of unstated length; the pricing capture held neither plan names nor amounts
Established in: Not stated by the vendor
Built for: Buyers who want security documents and a DPA visible before talking to anyone
Not for: Anyone who must see plan limits and prices before a trial
01
Why buyers look past DebugBear
01
The price list could not be read
DebugBear's pricing page loaded for us only as navigation and a footer, with a notice that JavaScript is required, so no plan names or amounts could be captured. Its pages lead with a Start Free Trial button and say no credit card is needed, but a team that wants to forecast a yearly bill has to open the live page in a browser or ask.
02
One vendor, several products to weigh
The site separates synthetic monitoring, real user monitoring, uptime monitoring, user flows and CrUX competitor data into different pages. A site owner who needs only scheduled Lighthouse runs must work out which parts of that set apply, and the answer shapes the number of pages, projects and users counted on the bill.
03
Little stated about who runs it
The about page names Matt Zeunert as founder and shows four people under Meet the team, but gives no country, and points to a procurement page for the registered address. The footer shows DebugBear Ltd. A buyer who needs a stated location for a vendor register should confirm it directly.
you only need an occasional single-URL check and no account

What each one does differently

Request Metrics
Not stated by the vendor · Published
Request Metrics comes from TrackJS LLC and puts its plan ladder on the page, which answers the forecasting problem directly. Scheduled Lighthouse runs and real visitor data feed the same Core Web Vitals view. The entry plan covers one site, one seat and 1,000 monthly visits, keeping data for just 24 hours, so growing sites move up quickly.
Switch from DebugBear if you want a plan list you can read and one small tool for lab and field data.
SpeedVitals measures from more than 30 locations and devices, the same breadth DebugBear quotes, and adds TTFB tests, batch testing and RUM. Allowances are counted as test credits per week, 15 on the Free plan and 3,500 on Ultimate. Free needs no card, and monitoring there runs once every 24 hours.
Switch from DebugBear if you want to try location-based tests without entering a card.
PageVitals schedules Lighthouse tests and adds performance budgets and multi-step tests, which suits checkout or login flows rather than a single address. CrUX tracking and real user monitoring sit alongside. A 14-day trial needs no card. The pages we read named no legal entity or country, and amounts were not returned.
Switch from DebugBear if budgets and multi-step flows matter more than a single-URL score.
Treo d.o.o. builds its view on Chrome UX Report data combined with Lighthouse, split into three products called Pages, Sites and Scan, the last scanning a sitemap. The footer carries a VAT number and a Made in the EU line, though no country is written out. The pricing capture returned no plans, so cost needs a direct question.
Switch from DebugBear if you want a sitemap-wide sweep and a vendor that describes itself as EU-made.
Calibre Analytics Pty Ltd, governed by Victoria law, meters RUM sessions and synthetic tests but leaves the number of sites open. Starter allows 5,000 of each monthly with three seats; Team allows 10,000 sessions and 15,000 tests with ten seats. A 15-day trial runs first, and EUR or AUD payment is offered.
Switch from DebugBear if you run many small sites and prefer paying by sessions and tests.
Sitespeed.io is an MIT-licensed toolkit installed by Docker or npm. A run yields an HTML report with Core Web Vitals, a page-load video, a HAR waterfall and Coach advice. Metrics can be sent to Graphite or InfluxDB for Grafana. Android and iOS Safari are supported, while scheduling and alerting are for you to assemble.
Switch from DebugBear if you have engineers who would rather run the test machinery themselves.
Lighthouse CI lives in the GoogleChrome GitHub organisation under the Apache-2.0 licence. Its stated aim is running Lighthouse on every commit, viewing the changes and preventing regressions, through tools that run, save, retrieve and assert results. It sits inside a build pipeline, and the repository names no service or support plan.
Switch from DebugBear if a failing build should block a slow change before release.
SpeedCurve builds Starter from sliders that reach 100 million RUM page views and 500,000 synthetic checks, starting at 90 dollars a month, with unlimited teams and users. Growth starts at 576 dollars and adds 13 months of retention and priority testing. Enterprise adds single sign-on and private agents. No trial is named.
Switch from DebugBear if you need long history and large traffic volumes with unlimited users.
Uptrends is owned by ITRS and treats speed as one use of a general monitoring product. Core starts at 42 dollars a month billed annually with 10 users, and Pro at 60 dollars adds 25 users and 230+ checkpoints. Credits meter every check, 6 for uptime and 50 for a browser check. A 30-day trial needs no card.
Switch from DebugBear if uptime, status pages and speed should live in one account.
SolarWinds Pingdom sells synthetic checks and real user monitoring as two separate ladders. Synthetics tiers run from 10 to 30,000 uptime checks, and RUM tiers start at 100,000 pageviews and reach a billion, with 13 months of data. Users are unlimited. The captured page showed 'Starting at' without amounts.
Switch from DebugBear if you want a long-established monitoring brand with RUM sized by pageviews.
PageSpeed Insights is provided by Google and asks for a URL and an Analyze click. It is the reference many people already use, with a v5 documentation page linked for the API. The page we read stated no price or quota and showed no history or scheduling, so it answers one-off questions only.
Switch from DebugBear if you only need an occasional single-URL check and no account.
You want a plan list you can read before signing up
Request Metrics: The ladder is on the page, and the entry plan covers one site and one seat with 24 hours of retention.
02
You want a failed build when a page gets slower
Lighthouse CI: It runs Lighthouse on every commit and asserts against results, under the Apache-2.0 licence.
03
You want to run the test lab on your own servers
Sitespeed.io: MIT-licensed, installed with Docker or npm, with HAR waterfalls, video and Grafana metrics.
04
You need long retention and very high traffic volumes
SpeedCurve: Sliders reach 100 million RUM page views, and Growth adds 13 months of retention from 576 dollars.
05
You want uptime checks and status pages next to speed
Uptrends: Speed is one use of a credit-metered monitor, with a 30-day trial that needs no card.
04
When DebugBear is still the right choice
DebugBear remains a sensible choice when you want lab tests, real user data and CrUX competitor comparison in one hosted service. Its pages list tests from over 30 locations, performance budgets across projects, and integrations with GitHub, Vercel, Netlify and Slack. The Trust Center, Security page and Data Processing Agreement in the footer also help a procurement review move quickly.
05
What moving off DebugBear involves
01
Rebuild the test set by hand
Lab tests, budgets and alert rules live inside DebugBear projects, and our pages show no export route. List every monitored URL, device profile, network setting and threshold before leaving, then recreate them in the new tool and run both for a few weeks.
02
Expect new baselines
Scores differ between tools because test locations, throttling and Lighthouse versions differ. Do not compare old and new lines directly. Mark the switch date in your reporting and agree fresh budgets from the first month of data in the new tool.
06
Questions about replacing DebugBear
6 answers
How much does DebugBear cost?
We could not read its prices. The pricing page returned only navigation text and a note that JavaScript is required, so check the live page.
The site offers a Start Free Trial button and says no credit card is required, but does not state the trial length.
Which alternatives publish their prices?
Request Metrics, SpeedCurve, Calibre and Uptrends list amounts or plan limits on their pages. SpeedCurve starts at 90 dollars a month, Uptrends Core at 42 dollars billed annually, and Calibre meters sessions and tests. Pingdom, PageVitals and Treo pages we read showed no amounts.
Is there a free option for a small site?
Request Metrics lists a free tier with one website and 24 hours of retention, SpeedVitals has a free plan with 15 weekly credits, and PageSpeed Insights needs no account. Sitespeed.io and Lighthouse CI are open source and cost only the machine you run them on.
Can I run the tests inside my own build?
Lighthouse CI is designed for running on every commit and asserting results. Sitespeed.io installs through Docker or npm and sends metrics to Graphite or InfluxDB. DebugBear itself lists GitHub, Vercel and Netlify integrations for the same job.
Do the alternatives cover real user monitoring?
Request Metrics, SpeedVitals, PageVitals, Calibre, SpeedCurve and Pingdom all list real user monitoring. Treo works from Chrome UX Report data instead, and Lighthouse CI and PageSpeed Insights measure in a lab.
Where are these vendors based?
Few state it. Calibre is governed by Victoria law in Australia, and Treo says Made in the EU without naming a country. DebugBear, SpeedVitals and the others we read did not state a country on the pages we saw.
