Know about API breaking changes before production does
Deprecast watches only the API vendors your app uses. Weekly digest + urgent deprecation alerts from OpenAPI diffs and changelogs — not another observability bill.

API contract changes break production without warning
You ship on Stripe, Twilio, OpenAI, Shopify, GitHub… and a dozen others.
Vendor sunsets land in ignored marketing emails. Changelogs scatter across ten browser tabs. The break shows up in production — or worse, in an angry customer ticket.
Status pages tell you when they’re down. Nothing tells you when the contract of the API is about to change.
Deprecast is a breaking-change radar for the vendors you mark in-use
- 1.Pick from the pack: enable only the APIs your app actually depends on.
- 2.Public signals watched: OpenAPI/Swagger diffs where specs exist; RSS and changelogs otherwise.
- 3.Two lanes of email: a weekly digest worth skimming, plus urgent alerts when a sunset is near.
- 4.Stay in control: thumbs up/down on each event (with optional reason chips) so the feed learns what matters to you.

Frequently Asked Questions
Do you need my API keys?
No. Deprecast uses public OpenAPI specifications, RSS feeds, and vendor changelogs only. We never require or accept customer API keys.
Is this uptime monitoring?
No. Deprecast monitors contract changes, deprecations, and parameter removals — not HTTP 500 downtime or server outages.
Are you BreakWatch or breakwatch.dev?
No. We are Deprecast (Code Stacked). Unrelated product and company.
Can I add any vendor URL?
Not in the Indie v1 30-pack. Custom vendor URLs are on our Studio roadmap.
Will you spam my inbox?
Urgent alerts are strictly rate-limited (max 3/user/day). Weekly digests are delivered once per week. Rate feed quality with thumbs and disable vendors you do not need.
