You changed the code — did anything break? TestSprite writes the end-to-end tests you never get to, runs them on your app, and tells you exactly what broke.
Trusted by 100,000+ developers and 50,000+ teams.

The verification gap
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.
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.
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
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
Three things make the difference between shipping fast and shipping broken.
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.
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.
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.
How it works
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.
Get started freeInstall the CLI, add the MCP server to your editor, or paste a staging URL in the dashboard. Same verifier either way.
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.
Dozens of cases go at once on our machines, not yours, so a full pass takes minutes rather than a nightly window.
From there it runs without you — nightly, and on every pull request.
Always on
A verifier that runs when someone remembers to run it protects nothing. Give it a schedule and a merge gate.
Every merge
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
Nightly, weekly, or ahead of each release. Silent breaks surface on their own instead of during a demo.
Every run, kept
Verdict, video and trigger, all retained — so you can see when a test started failing, not just that it is.
One engine, every surface
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.

Plug in through the open-source CLI, or MCP in your IDE. Your agent writes the code, TestSprite verifies it, and nothing about your workflow changes.

Nora is a pixel-art study operating system built on published learning science. It combines FSRS-6 spaced repetition, Feynman-style explanation grading, a research desk with real academic citations, a memory garden, and a cozy pixel world where a companion grows as your understanding deepens. Every AI interaction is grounded in real sources — the AI teaches, never thinks for you. Built and verified through a genuine 55-iteration write → verify → fix → verify loop using the TestSprite CLI.
