APIs that Document & Test Themselves

Optic automates the tedious part of building great APIs

Accurate API Specs

Optic maintains your API spec to save time, and ensure accuracy.

Automated Testing

Live testing with spec coverage makes testing Optic APIs easy.

Beautiful Docs

Stripe-style documentation for every API managed by Optic.

How it works

Optic keeps your API and spec in-sync

Behavior Monitoring

Optic monitors how APIs behave in your local, development and staging environments.

1

Diffing Observed Behavior

Optic compares your API's actual behavior to how the specification says it should behave.

2

Easy Resolution

Resolve unexpected behavior by updating your API spec or creating a bug report in your issue tracker.

3

Try It Yourself

You'll see that Optic feel a lot like using Git, but instead of code changes it's versioning your API changes.

Large organizations lack a definitive understanding of their service catalogs, and standardized documentation is rare. Optic offers the visibility that is essential to any governance effort in these complex environments.
