Show HN: Sentinel – open-source QA agent that reads your code before it clicks anything
Summary
Sentinel is an open-source QA agent that reads the codebase before interacting with an app, deriving and executing end-to-end tests across frontend and backend. Using a flow-driven architecture, it recon, plans, and tests multiple user flows with Playwright and API checks, surfacing defects that UI tests alone might miss. The project emphasizes safety with wallet testing, a lightweight stack, and MIT licensing.
