I'm the founder of Diffmon — change insurance for APIs and web interfaces you depend on but don't control.
What I'm building: A workspace-first platform that detects breaking changes in JSON APIs, HTML content, and JS-rendered pages before they hit production. Think schema drift detection, not uptime monitoring.
Why it matters: 67% of developers have experienced unexpected API breaking changes. Most monitoring catches downtime — Diffmon catches the silent structural shifts that break your parsers, integrations, and pipelines without triggering a single alert.
The stack: Next.js, TypeScript, Prisma, Redis/BullMQ, Playwright for browser rendering. Deterministic diffing with Smart Schema Validation.
