APIGuard

Find out about a breaking API change before your users do.

Vendors ship silent breaking changes. You find out when production falls over and customers complain. APIGuard watches SDK release feeds and flags breaking changes — with impact analysis — the moment they land.

How it works

Monitors release/changelog feeds for the APIs you depend on
An LLM classifies each change: breaking vs. non-breaking, and what it touches
You get a plain-English alert with impact analysis — not a raw diff

Launch coverage: OpenAI, Stripe, Anthropic, Supabase, Twilio — expanding to any SDK with a clean release feed.

Pricing
