SpecViewer vs Swagger Editor
Both tools work with OpenAPI/Swagger specs, but they're built for different jobs. Here's how they compare so you can pick the right one for your workflow.
| SpecViewer | Swagger Editor | |
|---|---|---|
| Primary focus | Viewing, organizing, and comparing multiple specs | Authoring and validating a spec while you write it |
| Multi-spec management | Yes — sidebar list with folders, switch instantly | One document at a time |
| Visual diff / compare | Built in — side-by-side visual diff of two specs | Not built in |
| Account required | No | No (for the free hosted editor) |
| Data storage | Browser localStorage only, nothing uploaded |
Depends on hosting/deployment |
| Publisher | Independent, open source | SmartBear (Swagger) |
When to use SpecViewer
You already have one or more OpenAPI/Swagger specs and want a fast way to browse, test endpoints with Try It Out, keep several specs organized, and visually compare versions — all without installing anything.
When to use Swagger Editor
You're actively writing or heavily editing a spec from scratch and want real-time validation as you type.
