DeepDoc vs Theneo

DeepDoc turns a code repository into a navigable documentation site, regenerating pages affected by code changes through its update command. It scans source files, plans and generates documentation, stages OpenAPI references when present, and builds a site organized around topics such as architecture, endpoints, integrations, and schemas. Its AI answers can cite repository file paths and line ranges. Listed inputs include Python, TypeScript, JavaScript, Go, PHP, Vue, GraphQL, and OpenAPI or Swagger specifications. Output options include Markdown, Mermaid diagrams, a MkDocs Material site, a static Next.js/Fumadocs site, and an interactive API reference. Generated sites can include navigation and search, with an optional AI chatbot widget. DeepDoc is a terminal-based Python package requiring Python 3.10 or later; the maker says it needs no account or cloud service and identifies it as MIT licensed. Users bring their own LLM provider. Generate and update call that provider, so costs depend on the chosen model and documentation pages; other listed commands do not call an LLM. The deploy command produces a static site for any host.

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.
