Breakwater — API Change Monitor

Monitor official API changelogs, catch breaking changes and deadlines, and plan migrations locally in Chrome.

Breakwater monitors official developer changelogs and release feeds, then surfaces the API changes that match your production stack. It gives teams a focused place to understand risk and plan migrations before a deadline. Key capabilities: - Choose from 60 curated official changelog and upstream release sources. - Add up to 100 custom HTTPS RSS or Atom feeds per browser with Pro. - Prioritize breaking changes, deprecations, security updates, authentication changes, webhooks, rate limits, and policy updates. - See an Answer Band based on real platform, category, and Stack-filter matches. - Track explicit effective dates, owners, private notes, status, and migration checklists. - Search, save, snooze, and safely import or export configuration. - Work in the Chrome Side Panel with keyboard navigation and dark or light themes. Local-first by design: Breakwater does not inspect source code, visited pages, or browsing history and has no user account, analytics, advertising, or application backend. Settings, custom source URLs, notes, reading state, and feed history stay in Chrome local storage. Feed markup is converted to plain text and never rendered. Optional feed access is requested only for the exact HTTPS origin selected by the user. Pro license keys and optional Slack webhook URLs are stored locally. They are transmitted only over HTTPS to Polar for license operations or to Slack when the user explicitly enables alerts. Free monitors any 3 of the 10 core sources with 1 Stack, daily checks, and 30-day history. Pro unlocks all 60 curated sources, custom RSS/Atom feeds, unlimited Stacks, hourly checks, 90-day history, deadline reminders, and optional Slack alerts.
