I keep finding out about API breaking changes from production errors, so I'm building a changelog watcher

Short summary

A solo founder building products on multiple vendor APIs kept discovering breaking changes through production errors rather than notifications. They built BreakWatch, a tool that daily diffs public API changelogs, classifies breaking vs. informational changes, and alerts only when integrations are at risk. The post shares honest findings from scraping ten major API changelogs and asks the community whether the problem is worth solving at $29/month.

  • •BreakWatch daily-diffs public API changelogs and classifies breaking changes vs. noise
  • •Tested against 10 major APIs including Stripe, OpenAI, Anthropic, GitHub — all scrape cleanly after fixes
  • •Founder is in validation stage with a kill condition: if users say vendor emails are enough, the product dies

Generated with AI, which can make mistakes.
