## Overview

Theneo was built around a specific pain point: API docs that drift out of sync with the product because engineers export a spec, writers paste it into a docs tool, the API changes again, and nobody updates anything. Its answer is a single collaborative surface where humans and AI agents edit the same document at the same time, backed by AI that generates complete references from specs and keeps changelogs current with automatic breaking-change detection.

Beyond generation, Theneo is a full developer-portal builder. It supports REST, AsyncAPI, SOAP, GraphQL, and gRPC, offers a versioned API playground and code generation, and can export projects back to OpenAPI or Markdown. Branding controls include custom domains, global CSS/JS, and developer-portal templates, while access controls cover private endpoints, company and user management, and guest or external customer access.

For the AI era, Theneo ships an MCP server and llms.txt-ready output so agents can consume your docs as tools, and it remains a market leader among docs AI on benchmarks. It reports more than 18,000 companies using the platform, is SOC 2 Type II, ISO 27001 and 9001 certified and GDPR compliant, and serves B2B platforms, fintechs, and regulated industries where a single public docs site isn't enough.

## Pricing & Plans

Theneo is freemium. The Starter Package is free with one public project, up to two private projects, up to 20 team members, and limited AI usage. Business is $120/month per workspace with custom domains and branding, Growth is $400/month with custom CSS, custom AI prompts, up to 20 developer portals, and 1:1 support, and Enterprise pricing is custom with self-hosting and SAML SSO. Annual billing shows slightly higher list prices for Business and Growth.

## Key Features & Capabilities

- **Generate docs from any API spec:** Paste an OpenAPI, GraphQL, gRPC, SOAP, or AsyncAPI spec and Theneo builds a complete, navigable API reference with code samples and a versioned playground.
- **Realtime collaborative editing:** Engineers, writers, and PMs edit in the same document with live cursors, comments, version history, and one-click rollback, so docs stop drifting from the product.
- **Smart changelogs and drift detection:** Automatic changelog generation flags breaking changes as APIs evolve, keeping a timeline developers can trust.
- **AI assistant, MCP server, and llms.txt:** An Ask AI assistant answers developer questions from your docs, and an MCP server plus llms.txt make the content usable by coding agents.
- **Private per-customer portals:** Spin up branded, authenticated portals so each customer sees only the APIs, guides, and SDKs they pay for, with analytics on readership.
- **Enterprise governance and branding:** Custom domains, white-label branding, SAML/OIDC SSO, custom roles, audit logs, and self-hosting are available for enterprise and regulated teams.

## Primary Use Cases

- **Auto-generate API references (API platform teams):** Turn an OpenAPI, GraphQL, or gRPC spec into a complete, versioned reference with code samples and a playground in minutes instead of weeks.
- **Agent-ready developer experience (Developer relations):** Let developers and coding agents ask questions and get answers from your docs via Ask AI, an MCP server, and llms.txt.
- **Branded public developer portal (Product and technical writers):** Publish a branded docs site with a custom domain, white-label styling, and a changelog that signals breaking changes automatically.
- **Per-customer private portals (B2B SaaS and fintech):** Give each enterprise customer an authenticated portal that shows only the APIs and SDKs they pay for, with SSO and readership analytics.

## Strengths

- AI generates complete API references from specs, cutting the manual write-up most teams hate
- Realtime co-editing with live cursors and comments keeps engineers, writers, PMs, and agents on one page
- MCP server and llms.txt output make docs usable by AI coding agents, not just humans
- Per-customer authenticated portals with SSO suit B2B, fintech, and regulated use cases

## Limitations

- Advanced customization (custom CSS, per-customer portals) sits on higher-priced Growth and Enterprise tiers
- Enterprise-grade self-hosting and custom SSO require a sales conversation
- Rich feature set may be more than a small team with a single public API needs
- Some newer agent-oriented features are still rolling out
