Bug0 releases QA agent for regression testing with cached Playwright replays

Linearbytes released Bug0 QA Agent, a source-available Playwright library for agentic browser regression testing. The agent maps plain-English test steps to UI actions and caches them in Redis for faster CI replays, while assertions are verified by consensus of up to three LLMs and vision models.

• Tests are written in plain English inside standard Playwright specs
• Successful single-action steps are cached in Redis and replayed without LLM inference
• Assertions are not cached: Claude and Gemini evaluate them, a third model breaks ties
• Released under the Functional Source License 1.1 with a two-year non-compete
