One source of truth for every API your team ships.
Endrel pulls your scattered API documentation into a single, always-current workspace — imported straight from OpenAPI, Swagger, or Postman, and kept honest by AI that flags what's drifted out of date.
The problem
Your API docs exist. Finding the current version is the hard part.
Documentation lives in four places and agrees in none of them. By the time you find a spec, you can't trust it.
// lost
Buried in email
Specs land as attachments in a thread from three sprints ago that nobody can surface again.
// noise
Drowned in Slack
The link was shared once, scrolled past, and is now ten thousand messages deep.
// scattered
Tool sprawl
Postman here, Swagger there, a Notion page someone forgot — and no canonical home.
// stale
Quietly outdated
The endpoint changed last week. The doc didn't. QA finds out in production.
The cost: hours lost to searching, FE / BE / QA working off different truths, and features that ship slower than they should.
Why Endrel
A documentation tool that stays true after launch day.
Most API tools help you write docs. Endrel's job is keeping them findable, current, and trustworthy for the whole team — long after the first commit.
One canonical home
Every service, version, and endpoint in a single searchable workspace — so "where are the docs?" stops being a question.
Import & auto-sync
Bring in OpenAPI, Swagger, or Postman collections. When the spec changes, the docs follow — no manual copy-paste.
Built for the whole team
Front-end, back-end, and QA read from the same source. Comment inline and resolve mismatches without a meeting.
Access you control
Granular permissions per workspace and service. Share a public reference or keep an internal API locked down.
Search that finds it
Jump to any endpoint, parameter, or response by name. Stop grepping chat history for a URL.
Developer-native
A REST API, clean onboarding, and formats your team already uses. Endrel fits the workflow you have today.
AI Review
AI that reads your APIs and tells you what's wrong.
Centralizing docs is the start. Endrel's reviewer continuously checks your specs against each other and against your live endpoints, then surfaces the gaps before they reach a customer.
- Flags endpoints documented in one place but missing in another
- Catches response shapes that drifted from the published schema
- Spots inconsistent naming, auth, and error conventions across services
- Suggests clearer descriptions and missing examples as you go
