AI writes the tests.
Testery orchestrates them.
Fast and flake-free.
Your agent automates the tests. Testery runs them, gates the deploy, and gives you an audit trail that proves the build is genuinely green, so you're not blindly trusting AI.

AI writes code fast.
Who checks that it works?
AI agents generate code in seconds. But "it compiles" is not "it works." Flaky tests, broken edge cases, and green-looking CI that lies are how AI-written code reaches production broken. You need a layer that actually runs the tests, every time, and refuses to let bad code through.
The Testery Loop
A closed loop your agent drives from feature file to shipped. It keeps iterating until everything is green.
- 1Write the intentYou edit a feature file in plain-language BDD.
- 2AI generates the codeYour agent implements against the scenario.
- 3Testery verifies locallyThe tests run on your machine, fast and free.
- 4Iterate to greenAI and Testery loop until the tests pass locally.
- 5Deploy to a previewThe plugin helps AI ship to a feature environment.
- 6Feedback returnsPost-deploy results flow back to the agent.
- 7AI revisesThe agent acts on that feedback automatically.
- Green, then shipThe preview goes green and you release with confidence.
Everything the test step needs
Run the suite in minutes
Massively parallel cloud runs, up to 2-4x faster than a traditional grid, so feedback comes in minutes, not hours.
Kill flaky tests for good
Detect, quarantine, and intelligently retry flaky tests, and flag the ones that can no longer be trusted.
Gate every deploy
Status checks on every pull request. Nothing merges or ships until the tests are genuinely green.
Trigger downstream events
Run on a schedule, on deploy, or on every PR, and notify Slack, GitHub, Octopus Deploy, and more.
An audit layer for AI code
Independent, exportable proof of what was tested, what passed, and what changed, on every run.
Built for AI agents
Drive the whole platform from Claude Code or any MCP client, in plain language, without leaving your editor.
Don't take the AI's word for it
Testery runs your tests independently of the agent that wrote the code, so a passing build is a fact you can verify, not a promise the AI makes about itself. Every run is recorded: what was tested, what passed, what changed, and when.
- Independent verification: the system that grades the code isn't the one that wrote it.
- A durable, attributable record of every run.
- Exportable evidence for review and compliance.
- Results you can see, audit, and trust.

Frequently asked questions
Is it really free?
Yes. Running tests on your own machine through the Testery plugin and CLI is free, with results synced to your free Testery account for history and reporting. You only pay when you run on the Testery cloud at scale. No credit card to start.
Do I have to rewrite my tests?
No. Testery runs the frameworks you already use, in the repo you already have. Playwright, Cypress, Selenium, Robot Framework, and more. No walled garden, no rewrites.
I already have CI. Why Testery?
CI was built to build and deploy, not to run tests at high concurrency with flake handling, PR gating, rich reporting, and an AI feedback loop. Testery is purpose-built for the test step, so a full suite finishes in minutes instead of hours.
Can AI-written tests be trusted?
That is exactly the point. Testery runs the tests independently of the AI that wrote them, flags the flakes, and will not let code through until it is genuinely green. The agent proposes; Testery verifies and proves it.
How does it work with Claude and other AI assistants?
Install the Testery plugin for Claude Code, or connect the Testery MCP server to any MCP-compatible assistant. Your agent can then trigger runs, read results, rerun failures, and keep iterating until everything passes.
Is my data secure?
Authentication is tied to your Testery account and your assistant can only do what your account is allowed to do. Local runs execute on your hardware; you choose what syncs to the cloud.
Ship AI-written code you can trust.
