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.

01

Connect an API

Upload an OpenAPI spec or point Avanamy at a live API URL. We support authenticated polling for private APIs.

02

Detect changes

We classify breaking vs non-breaking changes and summarize what changed.

03

Analyze impact

Avanamy scans your connected repositories and shows exactly which files, functions, and line numbers are affected.

04

Alert before prod

Get notified the moment a breaking change is detected - before it reaches users, deploys, or on-call rotations.

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.
