FernlightOpenAPI docs in Confluence that tell you what broke
Turn any OpenAPI 3.0, 3.1 or Swagger 2.0 spec into interactive API reference on a Confluence page. Every update is versioned, and breaking changes are flagged automatically.

Everything your API readers need, nothing they don't
Built for teams moving off unsupported Connect apps and for anyone tired of pasting screenshots of Swagger UI into Confluence.
OpenAPI 3.1 support
OpenAPI 3.0 and 3.1, Swagger 2.0, JSON or YAML. Webhooks, oneOf/anyOf, nullable types and $ref all render properly.
Breaking-change detection
Removed operations, newly required parameters, changed types, dropped auth schemes and more, compared between any two versions.
Your specs stay in Confluence
Specs are stored as page attachments with version history. No external storage, no tokens to leak, no data egress.
Filter what you show
Choose tags or path patterns, and hide base URLs, deprecated operations or the API description, so one spec can feed many pages.
Code samples
cURL, JavaScript and Python requests for every operation, including auth headers, ready to copy.
Export-ready
Full-screen view for large APIs, plus a clean endpoint table when a page is exported to PDF or Word.
Catch breaking changes before your consumers do
Upload a new version of the spec and the macro compares it with the previous one. Changes are grouped by operation and graded:
- Breaking: removed operations, newly required fields and parameters, removed auth schemes.
- Warning: new enum values and other changes that strict clients may reject.
- Info: additive, non-breaking changes.
Pick any two attachment versions to compare release against release.
Readable reference, not a wall of JSON
Operations are grouped by tag and searchable. Each one shows parameters, request bodies, responses with headers, nested schemas, enum values and examples, next to a generated code sample.
Set up in under a minute
Type /OpenAPI in the editor. Pick an existing attachment, paste a spec, or upload a file, and a live preview updates as you configure.
While editing, spec-quality notes point out missing summaries, undocumented responses and other gaps.
Runs on Atlassian
The app is built entirely on Atlassian Forge. It does not call any external servers, so your API specifications and page content never leave Atlassian's infrastructure and inherit your site's data residency.
