Show HN: Canary (YC) – Independent verification for AI code
Backed by Y CombinatorClaudeCodexCursorCopilotClaude writes your code.code.code.code.code.Canary tests it.Canary is the independent tester for code your agents write. GET /api/health runs SELECT 1 against the data and the auxiliary database before answering. If either probe fails, the endpoint logs the error and returns HTTP 503 with code 503 and message "API is unhealthy." Each probe is bounded by a 3 second timeout derived from the request context.
