Good job! Pretty cool MCP from TestSprite team! AI coding + AI testing helps you build better software easily!
Agentic testing for AI-native teams.
AI ships code in minutes — verifying it hasn't. TestSprite uses your app like a real user — your agent fixes its own work before bugs reach you.
Try TestSprite on your live app — free, no install, first results in ~10 min.

The verification gap
The bottleneck moved from writing code to proving it works.
Agents report “done” on work that never ran.
An overnight agent will mark a feature complete when the page doesn’t even render — or quietly breaks something three files away.
Even the best agents regress ~12–25%.
The strongest run we’ve measured still broke ~12% of its previously-passing features in a single change. Weaker runs approached 25%.
Every verifier assumes a human at a screen.
IDE plugins and dashboards were built for a developer watching. An agent working overnight lives in the terminal — so its verifier has to too.
Why TestSprite
Not another test runner.A QA loop your agent drives.
Three things make the difference between shipping fast and shipping broken.
It actually uses your app — not just reads it and guesses.
TestSprite reads your code and PRD for context, then proves it against the running product: dozens of agents open your live app at once and click through every feature like a real user, driving a real browser or hitting a live API. Never assertions on mocks.
- Reads your code & PRD, then verifies the live app
- Replay any agent session as video
- Understands the product the way a user does
A failure bundle your agent can actually act on.
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. The agent reads it, fixes the code, and reruns.
- Machine-readable verdicts, not flaky pass/fail noise
- Auto-Heal repairs tests when the UI drifts
- Tied to one snapshot — no chasing moving state
A suite that grows with your code — and remembers what your model forgot.
Every passing test is kept. Each phase, TestSprite adds dozens more, so coverage grows in lockstep with the build. It becomes a memory no context window holds — a failing test puts a dropped requirement back in front of the agent, mid-task.
- Reruns everything on every change to catch regressions
- Scheduled re-verification for 24/7 reliability
- Backend + frontend + data, generated together
How it worksFrom install to a
From install to a
self-running QA loop in four steps.
No test scripts to write, no selectors to maintain. TestSprite learns your app, then tests it for you.
- Step // 01
Install & connect
Run npm i -g @testsprite/cli and drop in your API key. Or add the MCP server to Claude Code, Cursor, or Codex.
- Step // 02
It learns your app
Just point TestSprite at your product — it explores and understands how your app actually works. That understanding is the spec: no prompts, no test scripts. Bring a PRD if you have one.
- Step // 03
It runs on your live app
TestSprite plans and runs end-to-end tests in the cloud, driving a real browser or hitting real APIs — never mocks.
- Step // 04
Fix, rerun, grow
Get a failure bundle, let your agent fix the code, and rerun. Passing tests are kept, so coverage compounds every phase.
One engine, every surface
Web app, terminal, IDE, or CI— the same verifier.
However you build, TestSprite meets you there: a no-code web app for QA teams, a CLI for autonomous agents, an MCP server in your IDE, and a gate in CI.
No-code testing, right in your browser.
Paste a URL and watch a fleet of agents explore your app in a live preview grid. Replay any session as video, organize test lists, and schedule runs — no code, no setup. Built for QA engineers and product teams.
- Live preview grid — watch agents explore in real time
- Replay any run as video and share with your team
- Test lists, scheduling & dashboards for QA teams
The live proof · codercup.aiWe put frontier agents
We put frontier agents
head-to-head. In public.
At CoderCup, Claude Code, OpenAI Codex, and Google Antigravity each build the same ten-phase app under one clock — with TestSprite as the neutral referee, scoring every phase against 16–22 end-to-end test plans. The numbers below are what the verifier surfaced.
Self-evolve
0% 80%
One agent began a phase with zero target features working — and finished with ~80% passing after ten rounds of reading failures and fixing them. Same model. The only change: something to verify against.
Regression
~12%-25%
Even the strongest run broke ~12% of its previously-passing features in a single change. Weaker runs approached 25% — the #1 reason you still babysit an “autonomous” agent.
Requirements met
42% 92%
With a verification loop in place, feature delivery climbs from meeting 42% of requirements to 92% — and smaller, cheaper models reach frontier completeness given enough iterations.

It gives a coding agent a real QA loop from the terminal. You describe a behavior once; TestSprite runs it against your live app the way a user would, and returns a single failure bundle — failing step, screenshots, DOM snapshot, test source, root-cause, and a suggested fix. The agent fixes the code and reruns. It's open source under Apache 2.0.
Build at AI speed.
Ship with proof it works.
Give every coding agent a verification loop it can run on its own — and ship software that actually holds up.
