AI QA Engineer & AI Testing Platform | Momentic

QA Bench: Mo, Codex, Claude Code and Devin against 1,396 labeled bugs.Read the report
Mo is an AI QA engineer for web, iOS and Android apps. Point it at a URL or a build, and it files each bug with repro steps and a screenshot or recording.
Engineering teams at Notion, Quora, and Webflow test with Momentic.
Teams that ship every day run Momentic in production.
"Our team's experience with Momentic has been great. Setting up tests is simple and the developer experience has been fantastic."
Head of Developer Experience, Notion
"Having E2E QA be part of the development process, run this fast (6.3x parallel), and at this scale (for every single pull request) is a true dream. Seriously, a green CI now has a measurable impact on my sleep quality."
Founding AI Engineer, Coframe
"Momentic makes it 3x faster for our team to write and maintain end-to-end tests. Startups win by shipping faster and better, and Momentic enabled us to do exactly that."
"I just ran our first automated eval across 110 prompts. This would have taken well over an hour manually — I kicked it off in 5 seconds and it was done in 14 minutes. HUGE for us."
Engineering Manager, Runway
"I love working with Momentic. Especially after having years of previous experience in QA, it feels like riding a bike, except the bike is a supercharged electric one!"
Senior Productivity Engineer, Webflow
The bottleneck moved.
Writing code is no longer the bottleneck. Proving it works is. Run ten agents and you get ten diffs to check, and your test suite only covers the paths someone wrote down. We built Mo to be the AI QA engineer every team should have had.
Tell Mo what to test, and it files the bugs it finds. Approve a flow and Mo opens a PR that adds it as a Momentic test. Momentic runs your tests on every PR, nightly, or in CI.
Bug bash your web and mobile apps
Point Mo at a URL or an iOS or Android build and say what to test. Mo picks the flows and runs them.
Bug reports with repro steps and recordings
Mo files each bug with repro steps, expected and actual behavior, and a screenshot or recording.
Turn flows into regression tests
Mo turns a flow you approve into a Momentic YAML test and opens a pull request in your repo.
Run regression tests on every PR and in CI
Run saved tests on a schedule, on every PR, or in CI, and use the result as a required check.
AI testing on hosted browsers, iOS simulators and Android emulators, or in your CI.
