Apiary vs Theneo

Apiary is a hosted web platform for designing, documenting, prototyping, and testing APIs. Its editor supports API Blueprint and OpenAPI (Swagger), with instant validation and a live preview as descriptions are written. Publishing a description creates a mock server that returns the responses specified in it; the default limit is 120 requests per minute, or 5,000 with authentication. Automated tests compare real API responses with expectations generated from the description. Apiary also supports OpenAPI import, interactive references, code samples, and API versioning. Teams can manage document access with Admin, Editor, and Viewer roles, and sync with GitHub. Branch-based GitHub integration is available on Pro. The free plan costs nothing and permits unlimited API projects and five participants per project, but projects are public and teams are not included. Standard and Pro are deprecated, with plan changes handled by support request for current customers. Embedding interactive documentation is supported on Standard and Pro.

Theneo is a developer portal for publishing API references, guides, changelogs, and customer-specific private portals. It creates interactive API documentation from OpenAPI files, Postman collections, or Git connections, with code samples, live testing, and CI/CD sync. Supported formats include REST, AsyncAPI, SOAP, GraphQL, and gRPC. Teams can co-edit, comment, review changes, track versions, and roll back. AI tools include documentation generation, Ask AI answers, release summaries, MCP, and llms.txt support. Private portals can control API visibility by customer and include SSO options and custom branding. Integrations include GitHub and Bitbucket sync, a VS Code extension, Postman sync, CLI, SDK, and API access. Theneo lists SOC 2 Type II, ISO 27001, and ISO 9001 certifications and GDPR compliance; it describes AES-256 encryption at rest, TLS 1.2 or later in transit, and seven-day point-in-time backups. A free plan is available; Business starts at $120/month billed annually. Enterprise includes self-hosting on AWS, Azure, Google Cloud, or on-premises Kubernetes.
