How it works

1

Add API specs

Paste the URL to any OpenAPI/Swagger spec. We support JSON and YAML formats.

2

We monitor 24/7

Our crawler checks for changes on your schedule — daily, hourly, or every 15 minutes.

3

Get alerted instantly

Breaking changes? New endpoints? Schema updates? You get an email before it breaks your code.

Why SchemaWatch?

Prevent production incidents

Breaking API changes cause 40% of integration failures. Know before your code breaks.

Historical schema versions

Every schema version stored forever. Compare any two versions side by side.

Smart diff engine

We distinguish breaking vs non-breaking changes. Removed endpoints = breaking. New optional params = safe.

Works with any API

Stripe, Mollie, Adyen, KVK, CBS — if it has an OpenAPI spec, we can monitor it.
