The verification gap
Writing code got faster. Proving it works didn’t.
The tests that would catch it don’t exist.
End-to-end tests are the chore that loses to the next feature, every sprint. So the code shipping fastest is exactly the code nothing is checking — and coverage written by hand never catches up.
“Done” is not evidence.
A closed ticket, a green unit suite, an agent’s confident summary — none of them prove the flow still works. Unless something drives the running app, the first person to find out is a user.
One change breaks 12–25% of what worked.
We measured it in public: across ten build phases at CoderCup, a single AI-assisted change broke 12–25% of the features that passed the day before. Nothing in a standard pipeline is watching for it.
By the numbers
Three weeks, or ten minutes.
- ~10 min
- From a URL to your first 50–100 end-to-end tests.
- 100,000+
- Developers building with TestSprite.
- 50,000+
- Teams running it on their own product.
The suite you keep meaning to write: Two to four hours per end-to-end test is the published benchmark. Sixty tests is three to six weeks of your time — which is why it is still not written, and why the thing that would have caught last week’s regression does not exist.

Why TestSprite
Not another test runner.A QA loop your agent drives.
Three things make the difference between shipping fast and shipping broken.
It uses your app the way your users do.
TestSprite reads your code and PRD for context, then proves it against the running app: dozens of agents open it at once and work through every feature like a real user, driving a real browser or hitting a live API. No assertions on mocks — so a pass means a person could actually do it.
- Verifies the running app, not a mock of it
- Replay any session as video — evidence you can drop in a PR
- Frontend, backend, and data covered together
Failures arrive with a cause, not a wall of red.
When something fails, TestSprite returns one self-consistent bundle: the failing step and its neighbors, screenshots, DOM snapshots, the test source, a root-cause hypothesis, and a recommended fix. You — or the agent that wrote the code — read it, fix it, rerun. Nobody spends the morning deciding whether a red test is real.
- One bundle per failure: cause, evidence, suggested fix
- Auto-Heal repairs tests when the UI drifts
- Tied to a single snapshot — no chasing moving state
Every passing test is kept, so coverage compounds.
As you build, TestSprite adds more tests and keeps everything that passed, so coverage grows in lockstep with the app instead of decaying between releases. A failing test also puts a dropped requirement back in front of you mid-task — which no context window will do on its own.
- Reruns everything on every change to catch regressions
- Nothing to rewrite when a selector moves
- Coverage you can point at when someone asks what’s tested
How it worksFrom one command to
Get started freeFrom one command to
a suite you never had to write.
No test scripts to write, no selectors to maintain. Install it, point it at your app — it learns it, tests it, and keeps testing it.
- Step // 01
Install & connect
Install the CLI, add the MCP server to your editor, or paste a staging URL in the dashboard. Same verifier either way.
- Step // 02
It learns your app
TestSprite explores and works out how your app actually behaves. That understanding is the spec — no prompts, no test scripts. Bring a PRD or an API doc and it uses those too.
- Step // 03
It runs them in the cloud
Dozens of cases go at once on our machines, not yours, so a full pass takes minutes rather than a nightly window.
- Step // 04
Then hand it a schedule
From there it runs without you — nightly, and on every pull request.
Always on
It keeps running after you close the tab.
A verifier that runs when someone remembers to run it protects nothing. Give it a schedule and a merge gate.
- Every merge
A gate, not a report.
Every pull request is re-checked against the full suite before it lands, and the result posts to the PR — where the review already is.
- Every night
Re-verified on a cadence you set.
Nightly, weekly, or ahead of each release. Silent breaks surface on their own instead of during a demo.
- Every run, kept
Every run is kept, not overwritten.
Verdict, video and trigger, all retained — so you can see when a test started failing, not just that it is.
One engine, every surface
Terminal, IDE, CI, or browser— the same verifier.
However you build, TestSprite meets you there: a CLI for agents and CI, an MCP server in your editor, a gate on every merge, and a no-code dashboard for everyone else. One suite, one set of results, whoever triggered the run.
CLI · for agents
A verifier that lives in the terminal.
IDE · via MCP
Verification inside your coding agent.
CompatibilityWorks with the agents
Works with the agents
and IDEs you already use.
Plug in through MCP or the open-source CLI. Your agent writes the code, TestSprite verifies it, and nothing about your workflow changes.

It gives you an end-to-end suite nobody has to write. Point it at your app; TestSprite works out how it behaves, runs it the way a user would, and returns a single failure bundle for anything that breaks — failing step, screenshots, DOM snapshot, test source, root cause, and a suggested fix. It runs from the terminal, your IDE, CI, or the dashboard, and the CLI is open source under Apache 2.0.
