6 free alternatives to ReadMe

Read the Docs gives free open-source project hosting with public documentation hosting, ads-supported hosting, and the ability to clone public repositories. For open-source docs, the free tier is not a teaser and is described as free forever for that audience. It is a simpler path if your docs live in Git and you mostly need publish-on-commit hosting rather than a richer editing surface. Compared with ReadMe, the free offering is much less about interactive docs tooling and more about repository-backed publication. If your project is public and docs-first, it is a clean switch.

• Beats ReadMe: Free open-source project hosting with public docs and no stated usage cap for that audience.
• Falls short: It does not offer ReadMe-style interactive API docs, WYSIWYG editing, or built-in docs metrics in the free tier.
• Who should switch: Switch here if you maintain public, open-source documentation and want free repository-backed hosting.

GitBook's free plan gives an individual user a full docs workflow with a block-based visual editor, GitHub or GitLab sync, unlimited page views, preview deployments, full-text search, page analytics, interactive API playgrounds, and version history. It also includes comments, change requests, basic roles, import from common doc formats, and support tickets. The free plan is broad for solo work, so it suits builders who want a polished docs site without paying just to get core publishing and editing features. If your bottleneck is one-project collaboration rather than docs capability, GitBook is a strong alternative.

• Beats ReadMe: Unlimited page views, which is better than ReadMe's single-project, single-version free cap for a content-heavy site.
• Falls short: The free plan is limited to 1 free user, so it is weaker for team collaboration than ReadMe's included admin model.
• Who should switch: Switch here if you are working solo and want richer publishing, search, and preview tooling on the free plan.

Mintlify's free tier includes access to the full platform, a custom domain, the web editor, the MCP server, custom components, and agent optimizations. That makes it a good fit for teams that want a modern docs stack without starting from a narrow trial-style plan. The free offering is especially appealing if your docs workflow already lives inside Mintlify's editing and publishing model and you want a branded site from day one. It is less about long-term quotas in the free description and more about giving access to the product surface itself. Builders who want breadth of features first should look here.

• Beats ReadMe: Access to the full platform, which is broader than ReadMe's capped one-project, one-version free tier.
• Falls short: The provided free-tier details do not spell out the same request-history and log retention ReadMe lists explicitly.
• Who should switch: Switch here if you want a broad docs platform with custom domain support and minimal initial setup friction.

Bump.sh's free tier includes up to 10 API docs, up to 3 internal users, up to 20 external users, support for OpenAPI, AsyncAPI, and OpenAPI Overlays, plus CLI and GitHub integration, custom domain and logo, and documentation hubs. It is a better fit when you need to publish multiple API specs rather than one documentation project, and when your docs workflow is driven by schema files and API portals. The free plan is capped, but the caps are generous enough for a small docs collection. If your main pain is ReadMe's single-project limit, Bump.sh is a practical move.

• Beats ReadMe: Up to 10 API docs, which is far more room than ReadMe's 1 project free cap for API portal work.
• Falls short: Its free tier is narrower on user count and does not include ReadMe's documented request history and detailed logs.
• Who should switch: Switch here if you publish several API specs and want docs-portals built around OpenAPI or AsyncAPI.

Apidog's free tier covers the core API workflow for up to 4 users, including API client support, mocking, testing, documentation with unlimited views, real-time collaboration, unlimited sprint branches and versions per project, SQL database operations, and scheduled import every 3 hours. It is a strong option if your docs need to sit next to testing and request debugging in the same workspace. The free plan is more execution-oriented than ReadMe, which can matter if your team treats docs as part of an API development loop rather than a publishing layer. Builders who want docs plus API work in one free package should consider it.

• Beats ReadMe: Up to 4 users with unlimited test and collection runs, which is better for small team API work than ReadMe's 1 admin free cap.
• Falls short: Its free plan is weaker on documentation publishing polish and does not list ReadMe-style custom theming and content controls.
• Who should switch: Switch here if you want docs, testing, and API client workflows together for a small team.

SimpleLocalize's free entry gives access to 250 translation keys, unlimited strings, 10 projects, 10 languages, and 90 days of activity and history log. While it is primarily a localization product, it can be useful if your documentation problem is really multilingual content management. The free tier is more generous on project count and log retention than ReadMe's one-project, 24-hour-history setup, but it is not a docs platform in the same sense. If your priority is managing localized content across several sites or doc sets, it can be the better fit. Otherwise, it is a category shift rather than a direct replacement.

• Beats ReadMe: 10 projects and 90 days of activity history, which is much more room than ReadMe's single project and 24-hour logs.
• Falls short: It is not a documentation hosting platform focused on interactive API docs or docs metrics.
• Who should switch: Switch here only if localization and multilingual content management matter more than API documentation features.
