API Dependency Intelligence
Catch breaking API changes before production does
Avanamy diffs every versioned API change and maps it to the exact files and lines in your repos, so teams fix issues before production incidents.
Built for teams managing production APIs and real change workflows.
What Avanamy Does Today
OpenAPI diff & version history
Authenticated API polling
Organizations & role-based access
Impact analysis with file/line refs
The problem with API changes
You find out an API changed when production breaks. The changelog didn't tell you if your code was affected. Sound familiar?
“An API changed - but we didn't know until prod”
No one reads changelogs. And changelogs don't tell you which of YOUR endpoints are affected.
“We found out during on-call”
The first sign of breakage was a 3am alert. The API had changed 2 weeks ago.
“We didn't know which services depended on it”
12 services, 47 files, 0 visibility into which ones called that endpoint.
“Schema changes broke us silently”
A required field was added. Our code didn't send it. Silent 400 errors everywhere.
What is Avanamy?
A pipeline built for change detection, impact mapping, and early alerts.
Connect an API
Upload an OpenAPI spec or point Avanamy at a live API URL. We support authenticated polling for private APIs.
Detect changes
We classify breaking vs non-breaking changes and summarize what changed.
Analyze impact
Avanamy scans your connected repositories and shows exactly which files, functions, and line numbers are affected.
Alert before prod
Get notified the moment a breaking change is detected - before it reaches users, deploys, or on-call rotations.
How Avanamy Works
Continuous API monitoring with code-level impact analysis
Concrete Outputs
What teams get from Avanamy
Clear, actionable artifacts - not just notifications.
Diff reports
Versioned diffs with breaking vs non-breaking classification and concise summaries.
Impact maps
Exact file and line references across your repos for every affected endpoint.
Alert signals
Targeted alerts routed to the right teams before production is impacted.
AI-generated docsAI
Clean HTML and Markdown documentation generated from your specs with AI assistance.
AI Assist
Documentation and summaries as a bonus
Avanamy generates clean HTML and Markdown documentation from your OpenAPI specs and provides AI-generated change summaries. While impact analysis is the core value, having readable, always-current docs is a useful side effect.
Why Avanamy is different
Not just “something changed” - we show you what breaks and where.
Code-level impact
Other tools tell you an API changed. We tell you which files, which functions, and which line numbers in YOUR codebase are affected.
Schemas as contracts
We treat OpenAPI specs as the source of truth. Breaking changes are detected by analyzing the actual contract, not guessing from traffic.
Full version history
Every change is versioned, diffed, and summarized. Go back in time to see what changed, when, and what the impact was.
Works with private APIs
Authenticated polling means you can monitor internal APIs, not just public ones. API keys, bearer tokens, basic auth - all supported.
Team-ready from day one
Organizations, role-based access control, and shared workspaces. Built for teams, not just solo developers.
Pre-production feedback
Alerts happen when changes are detected, not when production breaks. Shift left on API dependency failures.
Stop finding out about API breaks in production
Join the beta and be the first to know when your API dependencies change - with exact impact analysis for your codebase.
We're selectively onboarding teams. Usually respond within 48 hours.
