OpenDocs vs ReadMe

Beyond the checklist: what else you get with OpenDocs

ReadMe is an API developer hub. OpenDocs is a documentation platform for everything your company publishes — product guides, help centers, SOPs, and developer docs — so the feature set leans toward publishing, collaboration, and making your docs useful to both people and AI.

Docs that AI agents can read

Every published space is served through a built-in MCP server, so AI assistants and agents can list your spaces, browse the page tree, read pages, and search your content directly. Published sites also expose an llms.txt index and a Markdown (.md) version of every page, which gives language models a clean, current copy of your docs instead of scraped HTML.

Two-way GitHub Sync on every plan

Connect a space to a GitHub repository and sync runs in both directions. A push to the repo updates pages through a webhook, and a save in the editor commits Markdown with YAML frontmatter back to GitHub. When both sides change the same page, conflict detection shows a side-by-side comparison and you choose which version to keep. There is no plan gate: it works on the Free plan too.

Bilingual spaces and AI translation

Publish the same space in more than one language. AI Translations turn your content into any of 38 languages using Claude on your own Anthropic key (your plan plus your Anthropic usage).

Fast search, custom domains, and a real API

Readers find answers with Ctrl+K search across the space. On Pro you publish on your own custom domain, with health monitoring on the domain. On Enterprise and Compliance, developers can also automate content through a full REST API documented with an OpenAPI 3.0 spec.

A compliance tier for regulated teams

For teams that must prove who approved what, OpenDocs offers a compliance tier with approval workflows, e-signatures on documents, and audit export — useful for SOPs, policies, and controlled procedures that an API-focused hub is not designed to manage.

Where ReadMe excels

Honest answers help you make the right call. Here is where ReadMe genuinely shines:

Interactive API reference

ReadMe is built around API documentation: an interactive API explorer where developers make real calls in the browser, personalized docs with user-specific API keys, and API usage metrics. If your product is an API and developer experience is your core business, ReadMe's depth here is the draw — and its free Starter tier is genuinely generous for solo API projects.

OpenDocs does not currently offer an interactive “try it” API console. If an in-page request runner is a hard requirement for your public API, ReadMe is the stronger fit for that specific feature.

Developer dashboard and usage insights

ReadMe's Developer Dashboard shows which endpoints developers call, where they fail, and who is affected. Teams that support large developer ecosystems get real operational value from it (offered as a paid add-on).

Which should you choose?

Choose ReadMe if your product is an API, you need an interactive reference with per-user API keys, and the $250+/mo investment fits your budget. It is the specialist tool for developer hubs at scale.

Choose OpenDocs if you're a small software company that needs professional product docs, help centers, and SOPs fast — with your whole team collaborating, AI writing and translations on every plan, and one flat, predictable price. Most teams that outgrow ReadMe's single-admin free tier find OpenDocs at $55/mo the natural next step, not a $250/mo jump.

A quick way to decide:

• Your docs are mostly an API reference that developers try live → ReadMe.
• Your docs are guides, help articles, onboarding, and internal procedures → OpenDocs.
• Non-developers need to write and edit → OpenDocs, with its visual block editor and 5 members on Pro.
• You publish in more than one language → OpenDocs, with bilingual spaces and AI Translations.
• You want AI agents to answer from your docs → OpenDocs, with the built-in MCP server, llms.txt, and per-page Markdown.
• You need approvals and e-signatures on controlled documents → OpenDocs, with its compliance tier.

Pricing comparison

ReadMe's paid plan starts at $250/mo billed annually, and teammate invites, review workflows, and private docs sit behind that tier. Add the Ask AI add-on ($150/mo) and a realistic setup moves toward $500/mo before you count other paid add-ons such as the Developer Dashboard.

OpenDocs Pro is $55/month (or $45.65/month billed annually, $547.80/year) and includes 5 members. Additional members are $5/member/month on monthly billing, or $4/member/month on annual billing. OpenDocs Enterprise is $99/month (or $82.50/month billed annually, $990/year) with 10 members included, and adds analytics, PDF export, Markdown export, API access with full API docs, and audit logs.

You can also stay at zero. Every account starts with a 14-day Pro trial with no card; when it ends you continue free on 1 space, forever — your most recently edited space stays published as-is with a “Powered by OpenDocs” badge and 1 member — or you upgrade whenever you are ready.

Moving from ReadMe to OpenDocs

OpenDocs does not have a one-click ReadMe importer, so plan the move around the content you already have in Markdown. GitHub Sync is the path in: any Markdown files in a connected repository become pages.

1. Gather your guides as Markdown. If your ReadMe guides already live in a GitHub repository, that repository is your starting point. Otherwise, collect the guide pages you want to keep as .md files in a new repository.
2. Connect the repository via GitHub Sync. Add a GitHub Personal Access Token, point an OpenDocs space at the repo, and enable sync — available on every plan, including the Free plan.
3. Your pages import. Each .md file becomes a page, with YAML frontmatter mapping title, slug, order, and parent so your navigation comes across intact.
4. Invite your team and publish. Add members with Owner, Admin, Editor, or Viewer roles, set your custom domain and theme on Pro, and optionally run AI Translations to publish in more languages.

Keep your API reference where it works best. Many teams keep an interactive API console for the reference itself and move guides, tutorials, help articles, and SOPs to OpenDocs, where the whole team can edit them.

Frequently asked questions

What is the main difference between OpenDocs and ReadMe?

ReadMe is an API developer hub built around an interactive API reference, personalized docs with user-specific API keys, and API usage metrics. OpenDocs is a documentation platform for product guides, help centers, SOPs, and developer docs, with a visual block editor, team collaboration on the entry plan, and AI writing and translation on every plan.

Is OpenDocs cheaper than ReadMe?

For most documentation teams, yes. ReadMe's paid plan starts at $250/mo billed annually, and the Ask AI add-on is $150/mo. OpenDocs Pro is $55/mo with 5 members included, and Enterprise is $99/mo with 10 members. OpenDocs AI is bring-your-own-key, so you pay your plan plus your Anthropic usage.

Does OpenDocs have a free plan?

Yes. You start with a 14-day Pro trial with no card. After 14 days you continue free on 1 space, forever: your most recently edited space stays published as-is with a Powered by OpenDocs badge and 1 member. You can upgrade to Pro or Enterprise at any time.

Does OpenDocs have an interactive API explorer like ReadMe?

No. OpenDocs does not currently offer an interactive try-it API console. If readers must send live requests from your docs, ReadMe is the stronger fit for that feature. OpenDocs does provide a full REST API with an OpenAPI 3.0 spec for automating your own content, available on Enterprise and Compliance.

Can AI tools read my OpenDocs documentation?

Yes. Every published space is available through a built-in MCP server, and published sites expose an llms.txt index plus a Markdown version of every page, so AI assistants and agents can read current content directly instead of scraping HTML.

How do I move my docs from ReadMe to OpenDocs?

Put the guides you want to keep in a GitHub repository as Markdown files, then connect that repository to an OpenDocs space with two-way GitHub Sync, available on every plan. Each .md file becomes a page, and YAML frontmatter maps title, slug, order, and parent. There is no one-click ReadMe importer.
