Your API Changed.
Your Docs Didn't.
Until Now.

The Real Cost

API Documentation Drift Is Costing You

When API documentation falls out of sync with reality, teams lose weeks debugging phantom issues. 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."

r/SaaSIntegration Lead, 2025
Real story

"How do you get informed if a REST API changes? Normally you find out by your app crashing."

r/reactjsFrontend Developer
Common problem

"Endpoint was modified 6 months ago, but the documentation remains unchanged. We wasted days debugging what turned out to be a doc issue."

r/SaaSAPI Consumer
Documentation drift
The invisible cost: Documentation drift doesn't announce itself. You discover it when production breaks, when onboarding stalls, or when a 2-hour task becomes a 2-week investigation.
How It Works

Documentation That Stays Current

No more manual updates. No more stale docs. No more "wait, when did this change?"

Auto-updates in seconds

Live OpenAPI Sync

Point us at your OpenAPI spec URL. When it changes, your documentation updates automatically. No manual uploads, no stale docs.

GitHub integration

README Direct Imports

Import documentation directly from GitHub READMEs. When the source file changes, your docs reflect it. One source of truth.

Instant notifications

Breaking Change Alerts

Get notified via Slack or email when API schemas change. Know when endpoints move, fields deprecate, or auth requirements shift.

See what changed

Visual Diff Viewer

Side-by-side comparison shows exactly what changed. No more guessing which fields moved or what broke between versions.

Why Us

What Competitors Don't Do

ReadMe, Swagger UI, and Postman are great tools—but none of them keep your docs automatically in sync or alert you to breaking changes.

Use Cases

Built for Teams Who Integrate APIs

Whether you're building a marketplace, managing vendor integrations, or publishing internal APIs—live documentation changes everything.

500+
APIs monitored

API Marketplaces

Your marketplace has hundreds of third-party APIs. Developers browse, discover, integrate—then get surprised by API changes. Import each API's spec, monitor for changes, and alert developers before their integration breaks.

30%
fewer support tickets

SaaS Integration Platforms

Your platform integrates 50+ services (Salesforce, HubSpot, Stripe). When they update their APIs, your integrations sometimes break. Get alerted when vendor APIs change and plan migrations before customers are affected.

Days
not weeks to migrate

Internal API Teams

You publish internal APIs. When you deploy v2.0, documentation updates—but teams using your API don't know what changed. Notify dependent teams of breaking changes with a migration guide.

3 weeks
of debugging saved

Vendor Onboarding

Onboarding a new vendor API? Their docs are out of sync with the live endpoint. Import their spec, compare against reality, and flag discrepancies before you build the wrong integration.

FAQ

Frequently Asked Questions

How does live API sync work?
Point us at your OpenAPI spec URL (JSON or YAML). We poll it on a schedule you choose (hourly, daily, or on-demand). When changes are detected, your documentation updates automatically and you receive alerts based on your preferences.
What formats do you support?
We support OpenAPI 3.0, OpenAPI 3.1, and Swagger 2.0 specifications. You can also import README files directly from GitHub repositories. Both JSON and YAML formats are supported.
How do breaking change alerts work?
We analyze schema changes and classify them by severity: breaking (removed fields, changed types), warning (deprecated fields, new required params), and info (new optional fields). You choose which severities trigger alerts and where they're sent (Slack, email, or webhook).
Can I see what changed between versions?
Yes. Our visual diff viewer shows side-by-side comparisons of your API spec versions. You can see exactly which endpoints changed, which fields were added or removed, and how request/response schemas evolved.
How is this different from ReadMe or Swagger UI?
ReadMe and Swagger UI display your API documentation, but they don't keep it in sync or detect changes. You upload a spec, and it stays static until you manually update it. We monitor your live spec and alert you when it changes—automatically.
Can non-technical team members use this?
Yes. Unlike traditional API documentation tools designed for developers, our interface lets anyone see when APIs changed, understand what broke, and take action. No coding required to monitor or receive alerts.
What if the API I'm monitoring doesn't have an OpenAPI spec?
You can import documentation from GitHub READMEs, or we can help you generate an OpenAPI spec from sample requests. Many APIs publish specs even if they don't advertise them—we can help you find them.
How do I get started?
Import your first API spec in under 5 minutes. Paste a URL to your OpenAPI spec, configure your alert preferences, and you're done. No credit card required for the free tier.
