Visual API design
Design endpoints, schemas, versions, and parameters in a visual OpenAPI editor, with live preview and structured validation instead of hand-edited YAML.
Routebase
Routebase is an API lifecycle management platform for designing, mocking, testing, documenting, governing, and monitoring APIs from one living spec. It also includes a built-in MCP server so AI agents can work with APIs under team permissions.
Overview
Routebase is an API lifecycle management platform built around one living spec. It combines design, mocking, testing, documentation, governance, and monitoring so teams can work from a single source of truth instead of maintaining separate tools and drifting artifacts.
The product is positioned for API teams that want to define the contract first, then use that contract to drive realistic mocks, test suites, published docs, and agent access. It supports OpenAPI import and export, and every workspace includes a built-in MCP server for agent workflows.
Core capabilities
Spec-driven mocking
Create mock servers from the spec on a stable per-project URL, with customizable rules, static responses, CORS handling, and proxy mode for unmatched requests.
API testing and automation
Run tests against environments with chained requests, assertions on status, headers, body, latency, and schema, plus pre- and post-response JavaScript.
Living API documentation
Publish a docs portal generated from the spec, with access levels, custom domains, and language examples for each endpoint.
Agent-ready API workflows
Use the built-in MCP server so agents can discover, design, lint, and test APIs through the same workspace permissions as the team.
Governance and drift control
Apply governance rules, breaking-change checks, and drift monitoring so changes in the spec can be validated against live responses and review workflows.
Common use cases
API contract design
Define endpoints, schemas, and versions in a visual editor before implementation begins, then keep the contract valid as the API evolves.
Frontend and backend parallel work
Give frontend teams a realistic mock endpoint while backend work is still in progress, so client development can proceed in parallel.
API verification and regression testing
Run automated suites against staging or production-like environments to check behavior, schema conformance, and security findings against the spec.
Docs publishing from a live spec
Publish endpoint documentation from the same spec so the docs portal updates when the contract changes, without rebuilding separate documentation.
Agent-assisted API workflows
Let AI agents discover and operate on APIs through the workspace MCP server while keeping their actions within team permissions.
Pros and Cons
Pros
- Covers the API lifecycle in one workflow, from design through docs, tests, mocking, and monitoring.
- Uses a living spec as the source of truth, which helps reduce drift between contract and output artifacts.
- Supports OpenAPI 3.0 and 3.1 import and export, so existing specs can be brought in and exported again.
- Includes agent-facing tooling through a built-in MCP server with team-scoped permissions.
- Offers trial, free, and paid tiers, with the trial starting automatically and no credit card required at signup.
Cons
- Pricing is per user per month on paid plans, and the Enterprise plan requires a 25-seat minimum.
- The source does not show broad third-party integrations beyond OpenAPI import/export, Postman and Insomnia imports, and the built-in MCP server.
- Some capabilities are marked as launching soon or joining a waitlist in the source pages, so availability may vary by feature.
FAQ
How does the 14-day Pro trial work?
Every new account starts on a 14-day Pro trial with all features unlocked. No credit card or plan selection is required to begin, and the trial starts when you sign up.
What happens when the trial ends?
After the trial, the workspace moves to the Free plan automatically. Projects, specs, and history are retained, and you can upgrade later without losing your data.
Can I import existing API definitions?
Yes. Routebase supports importing OpenAPI specs directly, and it also accepts collections from Postman and Insomnia.
How do AI agents connect to Routebase?
Yes. Every workspace includes a built-in MCP server, and agents such as Claude or Cursor can discover the API as tools and work under the same permissions as the team.
Is Enterprise self-service?
Yes. Enterprise is self-service in the app, starts at 25 seats, and includes SAML SSO, SCIM provisioning, and audit log export.

Alternatives à Routebase
ByteAsk
ByteAsk is a terminal-first AI coding agent for C and C++ that edits repositories and verifies changes with the real compiler, debugger, sanitizers, and tests before showing a diff. It offers a free tier plus paid plans, with editor connectors and zero-retention handling described in the source.
Manta AI
Manta AI is an autonomous web app testing tool for teams that want to map application behavior, catch regressions, and generate tests without writing scripts or maintaining selectors. It works from a URL and supports plain-English test flows, run results with screenshots, and scheduled or deployment-triggered checks.
CreateOS Sandbox
CreateOS Sandbox is an isolated compute environment for running code and agent workloads inside Firecracker micro-VMs. It is designed for workflows that need machine-level isolation, private networking between sandboxes, and programmatic control through SDK, CLI, or MCP.
hob
hob is an independent workspace for coding agents that keeps agent sessions, terminals, history, and follow-up work organized around the tools and providers you already use. It is aimed at developers who want local control over routing, history, and workspace structure rather than a bundled model stack.
Ably Chat
Ably Chat is a chat API platform for building custom realtime chat applications. It supports room-based messaging, typing indicators, presence, reactions, and message updates, with usage-based pricing options for different deployment stages.
