Best Alternatives to Thousand in 2025

The all‑in‑one workspace

Notion is a highly flexible all-in-one workspace that combines docs, wikis, databases, and project management. It offers granular sharing permissions at the page and database level, making it easy to control access for team members, guests, and even API integrations. Unlike Thousand, Notion is not git-backed, but it provides a rich block-based editor, templates, and extensive integrations. It's ideal for teams that want a centralized hub for documentation and collaboration without relying on markdown or version control.

How people build software

GitHub is a natural alternative for teams already using git for code. It provides repositories with markdown files, folder-level access control via teams and permissions, and built-in wikis and GitHub Pages for documentation. While GitHub is developer-centric and lacks the polished documentation-specific features of Thousand, it excels at version control, collaboration through pull requests, and integration with CI/CD. It's a strong choice for technical teams that want docs to live alongside code.

GitBook is a modern documentation platform that syncs with Git repositories, allowing you to write in markdown and manage content in a git-backed workflow. It offers granular access controls, a clean reading experience, and collaboration features for both technical and non-technical users. Unlike Thousand, GitBook provides a hosted editor and publishing pipeline, making it easier to create public or private documentation sites. It's ideal for teams that want the benefits of git without managing raw repositories.

Confluence is a widely used enterprise wiki and documentation tool that offers robust permission management at the space and page level. It integrates deeply with Jira and other Atlassian products, making it suitable for large organizations. While Confluence is not git-backed and uses a rich-text editor, it provides powerful search, templates, and collaboration features. It's a good alternative for teams that need a centralized, permission-controlled knowledge base with enterprise-grade security.

Slab is a knowledge base and documentation tool designed for teams. It offers granular access controls, a unified search across connected tools, and a clean, distraction-free editor. Slab supports markdown and provides version history, though it is not git-backed. It's particularly strong for internal documentation and wikis, with features like topic-based organization and integrations with Slack, GitHub, and more. It's a solid choice for teams that value simplicity and powerful search.

Outline is an open-source, collaborative documentation tool that uses markdown and offers folder-level permissions. It can be self-hosted, giving teams full control over their data. Outline integrates with Slack, Figma, and other tools, and provides a fast, modern editing experience. While it doesn't have native git backing, it supports version history and is a great alternative for teams that want a lightweight, permission-aware wiki with the option of self-hosting.

Docusaurus is an open-source static site generator built by Meta, designed for documentation websites. It uses markdown and can be version-controlled with git, making it a close alternative to Thousand's git-backed approach. While Docusaurus lacks built-in folder-level access control (since it generates static sites), it can be integrated with authentication layers or deployed privately. It's ideal for technical teams that want full control over their documentation site and are comfortable with a code-based workflow.
