monit.rs · Zenofex LLC
OpenAPI change tracking that watches production, not just your spec repo. Ships the CI diff Bump.sh charges for — free.
What is different: Bump.sh is a docs-and-changelog platform driven by your OpenAPI files in git. monit.rs runs live probes against production, detects response-shape drift against the baseline (with or without a spec), and provides an equivalent CI-time OpenAPI diff via a free GitHub Marketplace Action.
Common ground: Both diff OpenAPI 3.x specs, classify changes as breaking/non-breaking/info, and publish a public changelog per API. Both integrate with GitHub PRs.
Pricing: monit.rs starts at $0 (3 endpoints, full monitoring + status pages + AI summaries). The CI-time OpenAPI diff Action is free with no account. Bump.sh Free covers 1 API doc; paid Hub tier starts at $149/mo.
Best fit: Choose Bump.rs if your primary need is a polished public docs surface with change history and you already treat your spec as the source of truth. Choose monit.rs when you need to detect the changes production makes that never show up in the spec — plus everything Bump.sh does at CI-time via the free Action.
monit.rs compares observed response fields and types with a learned baseline. Run OpenAPI contract checks against the latest stored response when you want to compare the implementation with a declared contract.
See the difference when a field disappears or changes type. Optional AI summaries suggest possible causes and next steps; review the evidence before accepting a new baseline.
monit.rs also runs a public changelog of 47+ well-known API vendors (Stripe, GitHub, OpenAI, Cloudflare, Datadog, PostHog, Vercel, Supabase, and 39 more). Every detected OpenAPI change is published at /changelog with per-vendor RSS feeds, stability badges, and side-by-side comparison pages.
