API Change Radar

Automatically monitor third-party APIs you call and alert on breaking changes

Problem

Developers rely on many third-party APIs (payments, maps, social platforms), but breaking changes often only appear in changelogs or doc updates and are easily missed. Problems surface only when things break in production.

Solution

Users subscribe to change sources of APIs they care about (changelogs, GitHub releases, doc diffs). The service periodically scrapes and analyzes changes, identifies breaking-change keywords, and notifies via email/Slack.

Users

Small teams and indie developers relying on multiple third-party APIs

MVP

Prebuilt list of change sources for common APIs; users select to follow; periodic scraping with keyword matching for breaking changes; email alerts; simple dashboard for history

Revenue

Free tier monitors 3 APIs, paid ($9/mo) for more and Slack integration

Why now

Modern apps depend on ever more APIs with scattered change notifications; indie developers can build aggregated monitoring at low cost
