Grapity vs Redocly

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.

Redocly is an API documentation and governance suite for teams creating, maintaining, and monitoring API experiences. Redoc generates reference documentation from OpenAPI definitions, with automatic code samples, mock servers, and interactive testing through Replay. Reunite supports collaborative editing, visual reviews, remote content, and deployment previews with an audit trail; it connects to GitHub, GitLab, Azure DevOps, or Redocly’s native Git solution. The open-source CLI validates, lints, and bundles OpenAPI definitions, while the VS Code extension helps write and maintain them and flags definition errors. Reef provides a searchable internal API catalog with metadata, scorecards, and discovery features. Respect monitors APIs against an OpenAPI specification and can send alerts through Slack or email. Redocly lists web, API, and extension platforms, custom domains, and content analytics. It says data is encrypted in transit and at rest and reports a completed SOC 2 Type II audit. Pro costs $10.00 per seat/month, billed monthly, and includes one project and 100 pages. API docs can be launched for free, and the full suite has a 30-day trial.
