Overview

Theneo is a developer documentation platform for building API references, developer portals, changelogs, and private customer portals in one place. It is positioned for teams that want documentation, guides, and API operations to stay aligned as the product changes.

The site emphasizes collaboration and automated updates. Theneo can generate docs from API specs or connected repositories, supports real-time co-editing, and includes tools such as a Try-it console, AI-assisted descriptions, changelog generation, and access controls for public or private documentation.

Core capabilities

Automated API reference generation

Upload an OpenAPI file, Postman collection, or GraphQL schema, or connect a Git repo, and Theneo generates interactive documentation with endpoint descriptions, examples, and code samples.

Interactive API testing

A built-in Try-it console lets readers send live requests from the documentation, with support for common auth methods and multiple environments.

Change tracking and release notes

Git-synced workflows detect spec changes, rebuild documentation, and support preview deployments, approval steps, and changelog generation.

Real-time collaboration

Engineers, PMs, and writers can edit in one shared environment with inline comments, role-based permissions, version comparison, and live collaboration.

Public and private portals

Theneo supports branded public docs, private portals, partner portals, and per-customer access controls for teams that need different visibility levels.

Branding and portal customization

The platform supports custom domains, branding controls, templates, and white-label options for teams that want their docs to match their product identity.

Common use cases

Generate API docs from specs
Teams can upload an API spec or connect a repository to produce a structured reference with examples, descriptions, and a Try-it console without building the docs manually.
Collaborate across functions
Product, engineering, and technical writing teams can edit the same documentation set together, resolve comments, and manage versioned changes in one workflow.
Run public or private developer portals
Companies that expose partner or customer APIs can publish branded portals with gated access, customer-specific visibility, and multiple documentation surfaces.
Track updates and publish changelogs
Teams shipping frequent API changes can use automatic changelog generation, breaking-change detection, and preview/approval flows to keep release notes current.
Control access for different audiences
Organizations serving enterprise or regulated buyers can use access controls, SSO-related options, and workspace permissions to separate audiences and manage who sees what.
