A gate on every merge
A crowdsourced cycle runs when you schedule it. A Momentic suite runs when the pull request opens, fails the build and names the step that broke.

Momentic vs Testlio
Testlio sends your release to vetted human testers in 150 countries. Momentic gives you a suite your coding agents write and CI runs on every merge. They do different jobs, and a team can run both.

What Testlio does
Testlio is managed crowdsourced testing. Its LeoCore platform matches vetted human testers to your release, runs the cycle, collects the findings and reports back, with bi-directional integrations and MCP support. The community reaches 600,000 devices, 150 countries, 100 languages and 800 payment methods, which is why Testlio is strong where a simulator cannot go: real payment rails, in-market localization, usability and accessibility with assistive tools. It is ISO/IEC 27001:2022 certified. Pricing is a platform subscription plus a consumption fund. What you buy is human judgement per cycle, not a suite that runs on every merge.
Where Momentic differs.
02
You keep the tests
A cycle leaves you a report. Momentic leaves YAML files in your repo that your coding agents extend on the next feature.
03
Cost per run falls
A human cycle costs the same each time you order it. You pay for an automated test once, when it is written, and your coding agent writes most of it. Quora cut a 7-hour QA pass to 30 minutes, so the suite now runs on every merge instead of once a release.
04
The suite repairs itself between releases
A human cycle re-tests the same flow from scratch each time you order it. Momentic re-resolves a moved target during the run and writes the repair back to the YAML, so the suite follows the product instead of ageing out of it.
05
Web, iOS and Android from one file set
One set of plain-English YAML runs against hosted browsers, iOS simulators and Android emulators, so the same suite gates the web app and both app stores. Notion, Retool, Webflow, Xero and Quora run it that way.
06
The flows that need a person are already automated
Sign-up, magic-link login and 2FA usually keep a human in the cycle. Momentic provisions the inbox and the phone number, and the test reads the code itself. Roo saves more than 200 engineering hours a quarter with that suite running on every merge.
07
Cached steps finish in under 500ms
After the first successful run, a Momentic step caches the signals it used to find its target. Repeat runs replay from that cache with no model call: a cached click averages 250ms, a type step 340ms, and over 99% of steps finish in under 500ms. The first run of an AI-assisted step is slower, 4 to 8 seconds to locate an element, and that cost is paid once.
08
The step sees more than a screenshot
Momentic resolves each step against a screenshot, the accessibility tree, and the DOM on web or the screen XML on mobile, and infers from the step description which signal matters. 'The Sign in button' resolves from accessibility attributes and text. 'The red Cancel button below the order summary' resolves from position and pixels. An element the screenshot does not show, or two that look alike, still resolves, and AI assertions read the same three sources.
09
Mo finds the bugs no test covers yet
Mo takes a target and a brief, plans the test cases, and runs each one in its own hosted browser, simulator or emulator, a hundred or more at once. A suspected bug goes to a reproducer agent that starts from a clean session, and only a reproduced bug reaches the report, with a recording and repro steps. One session ran 116 agents and returned 27 bugs. Testlio covers that ground with a crowd of testers on a cycle you order; Mo runs on demand and every finding comes with a reproduction.
Ten ways to test a release.
Testlio brings human testers to a release. The authoring column tells you whether a test can run again on the next pull request.
| Tool | Authoring | Runs on | Best fit |
|---|---|---|---|
| Momentic | Your engineers and their coding agents write plain-English steps over our MCP server, stored as YAML in your repo. Mo explores the app and reports bugs | Web, iOS and Android; CLI and CI | Coverage lands in the same pull request as the feature |
| Testlio | Managed manual testing by vetted testers | Web, mobile, real devices, in 150 countries | A live payment rail in a real market, or hardware you cannot host |
| Applause | Crowd testing, managed | Web and mobile at large scale | Wide device and market coverage for a release |
| Rainforest QA | No-code tests plus a crowd for manual runs | Web; vendor cloud | On-demand manual passes with fast turnaround |
| QA Wolf | Their engineers write and maintain Playwright tests for you | Web and mobile web; their infrastructure | Teams with no QA and no capacity to author |
| BrowserStack | Bring your own Playwright, Selenium or Cypress tests | Real browsers and real devices; vendor cloud | Buying browser and device coverage, not authoring |
| Playwright | Code: TypeScript, Python, Java or C# | Chromium, Firefox and WebKit; your runners | Engineers who want full control and accept selector upkeep |
| mabl | Low-code recorder aimed at non-technical authors, with JavaScript for the hard parts | Web and mobile web; vendor cloud | QA teams who record in a vendor app instead of writing code |
| MobileBoost (GPT Driver) | Their platform holds each test as a record. You change it through their REST API, or record it in their no-code editor | iOS and Android; simulators and real devices, 100+ in parallel | Mobile-only teams who need simulator features nobody else exposes |
| Autonoma | Open source. The platform plans the flows from your repo, and its agents use the app, so there is no test file to review | Real browsers and devices, for web, iOS and Android | Open-source first coverage, if a generated plan is enough |
Who should choose which.
Choose Momentic
Choose Momentic to gate every merge automatically, keep the suite in your repo, and let it repair itself as the product moves.
Choose Testlio
Choose Testlio when the test needs a human in a real market: a live payment rail on a real card, or hardware you cannot host.

Frequently asked questions.
Is Testlio a competitor to Momentic?
Yes, for the regression pass. Momentic runs payments, sign-up, 2FA and localized flows as automated tests on every merge, with provisioned inboxes and phone numbers for one-time codes. Testlio sells human judgement per cycle, for a live payment rail in a real market or hardware you cannot host.
Can Testlio run on every pull request?
That is not the model. Crowdsourced cycles are scheduled around a release. Momentic runs in the pipeline and returns a non-zero exit code.
Does Momentic test payments in real markets?
No. Momentic drives your app on hosted browsers, simulators and emulators. Live payment rails in 150 countries are what a service like Testlio is for.
What do we still own after each engagement?
With Testlio, a report per cycle. With Momentic, YAML tests in your repo that keep running.
Can we start without a QA team?
Yes. Your coding agent writes the first tests over our MCP server, and Momentic gates the merge from day one.
