Built with the test suite, not after it.
Web apps, APIs, AI agents and workflow automation, for teams that want the code and the tests delivered together.
Where to start
Development work is scoped after a discovery call. Every delivery includes the Playwright and API test suite and a CI pipeline that runs it.
See pricesWhat we build
- 01
Web apps and APIs
React and Next.js front ends. Node with NestJS or Python back ends. PostgreSQL. Delivered with end-to-end and API tests in CI.
- 02
AI agents
Tool-using agents and RAG pipelines on your data, with an eval suite that gates every change. Anthropic and OpenAI models, MCP integrations.
- 03
Workflow automation
Agentic and scripted automation that replaces manual operations. Idempotent, observable, tested with the same discipline as product code.
Proof
Checkout silently dropped orders under a race condition no test covered. We reproduced it, fixed it, and gated it with a regression test.
A timezone bug double-booked slots and overran the calendar. We corrected it across time zones and covered it with tests.
Questions
Why hire a testing studio to build software?
Because the tests are written by people who do that for a living, at the same time as the code. The suite is part of the delivery, not a follow-up quote.
Do you take over existing codebases?
Yes. It starts with the audit, which tells both sides what the codebase and its tests look like before a price is set.
Which stack do you not do?
Native mobile, and anything where we would be learning the framework on your budget.

Tell us about the suite and the CI. We say whether an audit makes sense and what it would cover.
