1.0 Design
Design the contract first
A visual OpenAPI editor for the whole contract — endpoints, schemas, versions — with the workflow of code.
14-day Pro trial — no credit card required.
Design without the YAML
Endpoints, parameters, and responses in a structured editor — the spec stays valid OpenAPI underneath.
- Three-panel editor: tree, form, live preview
- Path, query, header, and cookie parameters
- Undo/redo, keyboard shortcuts, auto-save
Model schemas once, reuse everywhere
Nested objects, arrays, enums, and references — with examples generated as you type.
- Visual JSON Schema builder with validation rules
- Reusable components via $ref
- Auto-generated examples per schema
Branch, review, merge
Draft on a spec branch, open a merge request, ship what survives review.
- Spec branches isolate work in progress
- Merge requests with review and approval flow
- Conflict and breaking-change detection before merge
Governance built in
Lint rules and breaking-change checks keep every spec on your style guide — automatically.
- 53+ style guide rules with auto-fix suggestions
- 21 breaking-change rules across versions
- Tag-based endpoint grouping with descriptions
OpenAPI in, OpenAPI out
Import existing specs, export anytime. No lock-in — the spec is yours.
- OpenAPI 3.0 and 3.1, YAML or JSON
- Validation against the spec schema on import
- Tag grouping preserved on export
One living spec
The rest of the lifecycle
Change the spec — everything on this page updates with it.
