Show HN: Routebase – One OpenAPI spec drives your docs, mocks, tests, monitors

Routebase launched a platform where one OpenAPI spec drives API design, docs, mocks, tests, and monitoring, with a built-in MCP server that turns APIs into agent tools. The product offers a 14-day Pro trial with no credit card required, and pricing starts at a Free tier with 1 user and 2 projects, scaling to Enterprise with 25 seats minimum.

One living spec drives your design, mocks, tests, and docs — and your agents work it like your team.

14-day Pro trial — no credit card required.

The lifecycle

Run the whole lifecycle from one spec #

Your APIs become agent tools #

Routebase ships an MCP server out of the box. Agents design, lint, and test through the same interface your team uses — no glue code.

  • 400+ MCP tools covering the full API lifecycle
  • Agents create endpoints, run test suites, and lint specs
  • Generate governance rules straight from your spec

Catch drift before your consumers do #

Scheduled monitors validate live responses against your spec and flag every divergence — missing fields, type mismatches, undocumented additions.

  • Live responses validated against the spec, continuously
  • Breaking changes flagged with field-level diffs
  • Missing fields, extra fields, type mismatches — every divergence classified

Branch, review, merge — for specs #

Draft on a spec branch, open a merge request, ship what survives review. Breaking-change checks built in.

  • Spec branches isolate work in progress
  • Merge requests with review and approval flow
  • Conflict and breaking-change detection before merge

Frequently asked questions #

How does the 14-day Pro trial work? #

Every new account starts on a full Pro trial — all features unlocked for 14 days. No credit card and no plan selection; the trial starts the moment you sign up.

What happens when the trial ends? #

Your workspace automatically moves to the Free plan. Nothing is deleted — projects, specs, and history are retained, and you can upgrade any time to pick up where you left off.

Do I need a credit card to get started? #

No. You only enter payment details when you choose a paid plan.

Where is my data stored? #

You choose EU or US data residency when you sign up, and your workspace stays in that region. Both regions run on Microsoft Azure.

Can I import my existing APIs? #

Yes — import OpenAPI specs directly, or bring collections from Postman or Insomnia. From there, your spec is the single source of truth.

How do AI agents connect to Routebase? #

Every workspace exposes a built-in MCP server. Agents like Claude or Cursor discover your APIs as tools and can design, lint, and test specs — under the same permissions as your team.

Is Enterprise really self-service? #

Yes. Enterprise starts at 25 seats and you subscribe directly in the app — SAML SSO, SCIM, and audit log export included. No sales call required.

Can I cancel anytime? #

Yes, in one click. Your plan stays active until the end of the billing period, then the workspace downgrades to Free with all data retained.

Ready to ship on it? #

Routebase is live. Design your API once — docs, mocks, tests, and monitoring all follow from the same source.
