Developer preview · API contract change review

Review API contract changes.
Understand the ripple impact.

ContractRipple gives frontend teams one workspace to store contract versions, review every classified difference, trace affected source files, and export the result — so you can decide before an update ships.

Start reviewing contracts See a demo report

Projects, analyses, and reports stay private to your account.

Built for a practical, explainable workflow

From contract upload to validation planning, ContractRipple surfaces findings in a clear, navigable format so developers can review changes with confidence.

Contract version management

Store and organize API contract versions in one place, with a clear history of every published change.

Diff review

See exactly what changed between contract versions — added, removed, or modified endpoints, fields, and types.

Impact reports

Trace changed operations into frontend files with source evidence, so you know which integrations to validate.

Analysis history

Keep a paginated log of past contract reviews and decisions, so nothing gets lost as the team grows.

Sample data

Sample diff between contract versions v2.1.0 → v2.2.0

5 changes detected

Demo impact report: sample contract changes between two example versions.
Type	Method	Endpoint	Detail
Added	POST	/v1/invoices	New endpoint to create invoices
Changed	GET	/v1/users/{id}	Response field `email` is now required
Removed	DELETE	/v1/legacy/items/{id}	Legacy item deletion endpoint removed
Added	GET	/v1/reports/export	New CSV export endpoint added
Changed	PUT	/v1/users/{id}	Request body field `phone` changed from string to object

Recommended next steps

Update the InvoiceForm component to handle the new POST /v1/invoices endpoint.
Add validation for the now-required email field in GET /v1/users/{id} responses.
Remove any calls to the deleted DELETE /v1/legacy/items/{id} endpoint.
Create a test suite for the new GET /v1/reports/export CSV endpoint.
