Your stack should define the catalog—not the other way around.
Start with ten focused changelogs. Pro unlocks 50 additional upstream release feeds across the technologies developers ship with, plus up to 100 custom HTTPS RSS or Atom sources per browser.
Runtimes & apps
Node.js, TypeScript, Python, Rust, Go, .NET, Flutter, React Native, Expo and Electron.
Cloud & data
Kubernetes, Terraform, Docker, AWS, Azure, Prisma, Redis, MongoDB, Grafana and more.
Your own sources
Add an official vendor feed or an internal public feed. Access is requested only for its exact HTTPS origin.
One answer before the feed.
Breakwater first tells you whether anything relevant needs attention. Relevance requires a real platform, category, and Stack-filter match.
Command Center
Triage the signal. Plan the migration.
Search, filter, save, snooze, assign an owner, keep private notes, and finish a migration checklist—without leaving the browser.
- Breaking changes and deprecations first
- Stable IDs and update timeline
- Stacks for distinct integration surfaces
- Safe configuration import and export
Explicit deadlines
A date only when the source states one.
Deterministic rules extract effective dates only from explicit language. Ambiguous posts stay informational, so false urgency does not become another alert.

Your integration map is not our dataset.
Breakwater has no backend. Settings, custom feed URLs, notes, reading state, and feed history stay in the browser extension’s local storage (chrome.storage.local is the cross-browser API name). Feed HTML becomes plain text and is never rendered. Optional source access is granted one exact origin at a time.

The important questions.
Does Breakwater inspect my code?
No. It compares official changelog metadata with the platforms, categories, and urgency filters you choose.
Where is my data stored?
In the extension’s local storage on your device. Breakwater operates no application server. Chrome and Edge keep separate storage; use the validated export/import flow when moving between browsers.
Which sources are monitored?
The catalog contains 10 focused changelogs and 50 official upstream release feeds across AI, web frameworks, runtimes, mobile, cloud, data, identity and commerce. The complete searchable catalog is visible inside the extension.
Can I add a specialized or internal source?
Yes. Pro can add up to 100 custom HTTPS RSS or Atom feeds per browser. Breakwater validates the feed and asks the browser for access only to that exact origin. Feeds requiring authentication or private-network access are intentionally rejected.
Can a changelog post run code in the extension?
No. Source markup is stripped. Breakwater renders its own React UI and plain text only; no remote code is permitted.
How do I activate Pro?
Choose a plan here or inside the extension, complete checkout with Polar, then paste the license key from your receipt into Breakwater Settings. One license supports up to three browser activations; each browser profile uses one activation.
Put a breakwater between a changelog and your next deploy.
