Docs that are still true the day after you ship.
Plenty of tools help you write API documentation. Endrel's job starts after that — keeping every spec findable, current, and trusted by the whole team for as long as the API lives.
What Endrel does
Six things that keep your API docs honest.
Each one exists to kill a specific way documentation goes stale, scatters, or quietly stops matching the code.
One canonical home
Every service, version, and endpoint in a single searchable workspace. "Where are the docs?" stops being a question, because there's exactly one answer.
Import & auto-sync
Bring in OpenAPI, Swagger, or Postman collections in minutes. When the underlying spec changes, the docs move with it — no copy-paste, no forgotten update.
Built for the whole team
Front-end, back-end, and QA read from one source. Comment inline on an endpoint and settle a mismatch without booking a meeting.
Access you control
Granular permissions per workspace and service. Publish a public reference or lock an internal API down to a single squad.
Search that finds it
Jump to any endpoint, parameter, or response shape by name. Stop scrolling chat history hunting for a URL someone pasted last month.
Developer-native
A REST API, clean onboarding, and the formats your team already uses. Endrel fits the workflow you have instead of asking you to adopt a new one.
One canonical home
One workspace your whole team trusts.
Services, versions, and endpoints live together in a structure that mirrors how you actually ship. Ownership is visible on every row, version history is kept, and there's never a second copy quietly disagreeing somewhere else.
- ›Browse by service, then drill into any version
- ›See who owns each endpoint at a glance
- ›No duplicate "final-v2-real" copies floating around
Import & auto-sync
Bring your specs in. Keep them in step.
Point Endrel at the formats you already produce. Import is a one-time setup; staying current is automatic. When a spec changes, Endrel re-reads it and updates the docs — so the page you read is the contract your code actually serves.
- ›Import OpenAPI, Swagger, and Postman collections
- ›Re-checks on every spec change — no manual updates
- ›One import covers every endpoint in the spec
Built for the whole team
Front-end, back-end, and QA on the same page.
When everyone reads from one source, the "which version did you build against?" conversation disappears. Comment directly on an endpoint, flag a mismatch, and resolve it inline — no thread to dig up, no meeting to schedule.
- ›Inline comments on any endpoint or field
- ›Resolve mismatches without leaving the doc
- ›Everyone sees the same current truth
Who it's for
One source of truth, four points of view.
Endrel earns its place for everyone who touches an API — not just the person who wrote the spec.
// front-end
Front-end devs
Build against the contract the back-end actually serves, not a stale copy from last sprint.
// back-end
Back-end devs
Publish a change once and trust it reaches everyone, with the spec as the single source.
// quality
QA engineers
Test against documented behaviour and catch drift before it ships to a customer.
// leadership
Tech leads
Know the docs are current without policing them, and onboard new engineers faster.
What changes
Less hunting. More shipping.
Hours back
The time your team spends searching for "the current version" collapses to a single lookup.
One shared truth
FE, BE, and QA stop building against different realities, so fewer surprises reach production.
Faster releases
When the docs are trusted, integration stops being the step that quietly slows every feature down.
Using Endrel
How the workflow fits your team
Practical answers about importing, collaborating, permissions, and moving at your own pace.
01Can frontend, backend, and QA collaborate on the same endpoint?
Yes. Endrel gives each role the same endpoint reference and keeps the discussion next to the API it concerns. Teams can flag mismatches, leave context, and resolve documentation questions without creating another disconnected chat thread.
02Can I control who can view or edit each workspace?
Endrel is designed around workspace and service-level access controls, so internal documentation does not need to be visible to everyone. During Founding Access, teams with strict security requirements should confirm the current permission set with us before adding sensitive specifications.
03What happens after I import an API specification?
Endrel turns the specification into a structured workspace of services, versions, endpoints, parameters, and responses. When the connected source changes, Endrel can re-read the specification so the documentation reflects the current contract instead of becoming a separate copy.
04Do I need to migrate all my documentation at once?
No. Start with one actively used API or service, confirm the workflow with the people who depend on it, and expand from there. A gradual migration is usually safer than moving every document before the team has agreed on ownership and structure.
