Semva wants to make API breakage predictable

semva.dev ↗ · Developer Corner · score 82.0
○Open: public page gives enough substance to understand the site $Paid: pricing, booking, ecommerce, subscription, or paid access is visible ADAds: visible ad load or ad-supported content ✦Pretty: notable design, copy, craft, or presentation ◆Pro: polished, finished-feeling, serious, or operationally mature ◇Niche: specific audience, workflow, or unusually focused use case ◉Human: personal, local, community, civic, handmade, or real-person signal !Suspicious: scammy, spammy, trust theater, finance fog, or credibility concern

Semva maps API dependencies, detects contract changes, and shows which teams and codebases are affected.

Why it surfaced

Its live example turns an OpenAPI release into an actionable incident: a newly required currency field is flagged as breaking, with checkout and billing identified as affected. The product also exposes the analysis through an MCP server, giving developers and AI tools a way to ask what changed and who needs to act.
