Grapity vs Routebase

Grapity is an open-source API governance platform for teams coordinating API contracts and their consumers. Its Registry compares each pushed specification with the previous version and blocks breaking changes with an explanation. It enforces semantic version increments and tracks deprecation lifecycles, including consumers and sunset dates. The Hub offers a searchable API list, endpoint exploration, side-by-side version comparisons, and a version timeline. Grapity governs OpenAPI and AsyncAPI formats, with CI/CD integration and role-based access control. For Kong, Grapity Gateway generates configuration from registered specifications, and the CLI provisions it through decK; Kong can also send access logs to the Registry using its http-log plugin for queries and traffic statistics. The project says it is licensed under Apache 2.0 and has no features locked behind paywalls. Self-hosted use costs nothing, billed forever, with unlimited APIs and team members. Cloud costs $29.95 a month and includes five APIs and five users.

Routebase is a hosted service for managing API work through a living specification, from design and testing to documentation and monitoring. Its visual editor lets teams create versioned OpenAPI specifications with endpoints and schemas. Publishing a version creates its documentation portal and mock server; tests and monitors then validate that version. Scheduled monitors compare live API responses with the specification and flag field-level differences. Routebase also includes a native Model Context Protocol server for agents to design, lint and test APIs. Integrations include event-driven webhooks, Slack and Microsoft Teams alerts, scoped API keys and MCP access for AI agents. The Pro plan adds governance and security scanning, including checks described against the OWASP API Security Top 10. Workspaces can be hosted in the EU or US, selected at creation. Routebase has a free plan and a 14-day trial; paid plans start at $9/user/mo (annual). It has no on-premise or self-hosted edition.
