five46

An autonomous AI testing agent that verifies your app or API actually works while you're still building it — fully local, using your own LLM key.

You just changed something, and you want to know — right now, against the real running thing — whether it actually works, without first writing a test yourself. Give five46 a plain-English goal — "log in and confirm the dashboard loads," "create a user via POST, then confirm it via GET" — and an LLM, using your own OpenAI, Anthropic, Gemini, Groq, or AWS Bedrock key, drives your real app or real API, one real action at a time, and tells you honestly whether it worked, with a root-cause hypothesis if it didn't. Once it does, that exact run is captured as a real, standalone Playwright (or node:test) spec you keep — so the same check that helped you while you were building the feature becomes a permanent regression test afterward, with no five46 or LLM involved in ever running it again.

Status: early proof of concept, verified end-to-end against real live LLM keys across dozens of real-world sites and APIs.

Why five46, and how it's different

Most testing tools assume you already have a suite to run. five46 is built for the moment before that — mid-feature, before a test exists at all. Point it at what you're building, describe the outcome you expect in plain English, and keep re-running it as you keep changing code; once it's solid, the run it just did becomes your regression test, not a separate thing you write afterward.

Most AI-driven test-generation tools also run in a cloud sandbox: your app's traffic, screenshots, and DOM leave your machine and go through a third-party service you don't control. five46 is the opposite bet — everything runs on your laptop, using a key you already pay for, and the only thing that ever leaves your machine is the text sent to your chosen LLM provider on each step (always disclosed, never hidden). If your organization can't adopt a cloud-hosted AI testing platform for compliance or trust reasons, this is built for exactly that constraint.

It's also not a black box: every run ends with a real .spec.ts/.test.mjs file you can read, diff, commit to your repo, and run in CI with plain npx playwright test — no vendor lock-in, no proprietary runner.
