Catch API Breaking Changes
Before They Break
Integrations.
Stop discovering API changes from production errors. Specway detects breaking changes the moment they happen and alerts your team before integrations fail.
API Changes Shouldn't Be a Surprise
When APIs change without warning, teams lose weeks debugging integration failures. Here's what developers actually say:
"We recently onboarded a new data provider. Initially, their documentation seemed accurate. However, we quickly encountered issues like missing fields, lack of pagination, and inconsistent responses. It turned into a frustrating three weeks."
"How do you get informed if a REST API changes? Normally you find out by your app crashing."
"Endpoint was modified 6 months ago, but the documentation remains unchanged. We wasted days debugging what turned out to be a doc issue."
From Spec Change to Alert in Seconds
A simple four-step pipeline that runs automatically every time your API spec changes.
Spec Changes
Your OpenAPI spec gets updated — whether you push a new version, a vendor deploys a change, or a CI pipeline publishes an update.
Diff Detected
We compare the old and new versions field-by-field, classifying every change as breaking, warning, or informational.
Alert Sent
Instant notification via Slack, email, or webhook with a summary of what changed and the severity level.
Docs Updated
Documentation auto-regenerates for affected endpoints. Changelog entries are created. Your portal stays current.
Everything You Need to Stay Ahead of Changes
Detect, classify, alert, and document — all automatically.
Visual Diff Viewer
Side-by-side comparison of what changed, what was added, and what was removed. See the exact impact on endpoints, fields, and schemas at a glance.
Severity Classification
Every change is classified: breaking (removed fields, type changes), warning (deprecations, new required params), or info (new optional fields). Focus on what matters.
Instant Alerts
Get notified via Slack, email, or webhook the moment a change is detected. Configure severity thresholds so you only hear about changes that matter to your team.
Auto-Generated Changelog
Changelog entries are created automatically with human-readable summaries of what changed and why it matters. Share with your team or publish to your developer portal.
The Only Platform That Does It All
Some tools detect changes. Some host docs. Specway is the only platform that detects changes, classifies severity, alerts your team, and updates your docs — all in one.

Built for Teams Who Depend on APIs
Whether you're consuming vendor APIs, publishing your own, or running an API marketplace — breaking change detection prevents surprises.
API Consumers Monitoring Vendors
You depend on third-party APIs (Stripe, Twilio, HubSpot). When they push a breaking change, your integration breaks and customers notice before you do. Monitor vendor specs and get alerted before the breakage hits production.
Internal API Teams
You publish internal APIs consumed by other teams. When you deploy changes, dependent teams need to know what broke and how to migrate. Auto-classify changes and notify consumers with actionable diffs.
API Marketplaces
Your marketplace lists hundreds of third-party APIs. When a listed API changes, developers integrating it need to know immediately. Monitor every listed spec and surface breaking changes to affected users.
SaaS Integration Platforms
Your platform connects 50+ services. When any vendor updates their API, your connectors risk breaking silently. Get ahead of vendor changes and plan migrations before customers are affected.
