What Theneo is

Theneo is a developer portal platform for publishing API references, guides, changelogs, and private customer portals. It builds interactive API documentation from OpenAPI files, Postman collections, or Git connections, with code samples, live testing, and CI/CD sync. Supported API formats include REST, AsyncAPI, SOAP, GraphQL, and gRPC. Teams can co-edit, comment, review changes, track versions, and roll back. AI tools include generated documentation, Ask AI answers, release summaries, MCP, and llms.txt support. Integrations include GitHub and Bitbucket sync, a VS Code extension, Postman sync, Theneo CLI and SDK, and API access. Authenticated customer portals can control API visibility by customer and offer SSO options and custom branding. Theneo lists SOC 2 Type II, ISO 27001, and ISO 9001 certifications, GDPR compliance, AES-256 encryption for stored data, TLS 1.2 or later in transit, and seven-day point-in-time backups. It offers a free plan, paid Business and Growth plans, and an Enterprise plan with self-hosting on AWS, Azure, Google Cloud, or on-premises Kubernetes. Theneo is headquartered in Seattle, Washington; its founder developed a prototype in early 2021 and released a public beta in August 2021.
