Key facts
Freero in facts you can check
Short statements about Freero, true of its code and documentation on the date below. Quote any of them as it stands, and link the statement itself: each one has its own address on this page.
Checked against the code on . No user counts or growth figures: only what the source code and its documentation show.
The facts
- What it is
Freero is a free, open-source, real-time collaborative whiteboard for teams of people and AI agents: sticky notes, diagrams, mind maps, kanban boards, tables and docs.
Check it: README
- How agents work
AI agents connect over MCP and, by default, can only read boards and propose changes; people accept or reject each proposal, and nothing changes until they do. Changing boards directly and commenting are separate permissions a person ticks on the consent screen.
Check it: MCP guide: permissions
- Who did what
Everything an agent adds is labelled with the app and the person it acts for (for example "Claude for Maria"), shown in the board’s activity and recorded in the audit log.
Check it: MCP guide: safety
- Licence
The whole codebase is under the MIT licence, including the MCP server, SSO, SCIM and tracker sync. There is no enterprise edition and no licence key.
Check it: LICENSE
- Price
Freero has no paid plans and no seats. Every feature is included, also SAML and OpenID Connect single sign-on, SCIM provisioning, the audit log and the admin console. Self-hosting costs only your own servers.
Check it: Pricing
- Limits
Instead of plan limits, a Freero server has default fair-use limits that its operator can change: for example 5,000 boards per account, 1 GB of uploads per account and 300 API or MCP requests per minute per token or connected app.
Check it: Pricing: default limits
- Self-hosting
Freero ships as one Docker image that serves the app, real-time collaboration, the REST API, the MCP server and the marketing pages. It needs PostgreSQL 15 or newer; Redis and S3-compatible storage let it run as more than one instance.
Check it: Deployment guide
- MCP endpoint
The MCP server is at https://freero.app/mcp (MCP Streamable HTTP). Clients sign in with OAuth 2.1 (PKCE and dynamic client registration) or send a personal access token.
Check it: MCP guide: how sign-in works
- MCP tools
The MCP server offers 40 tools and 4 prompts: find and read boards and docs, add notes, clusters, cards and diagrams that Freero lays out itself, propose changes, sync with issue trackers and run an agent control room.
Check it: Build with agents
- AI clients
Clients with a guided setup: Claude, ChatGPT, Claude Code, Cursor, VS Code, Codex, Windsurf and Microsoft 365 Copilot. Any other MCP client that speaks Streamable HTTP works too.
Check it: Integrations: AI agents
- Live board in chat
In hosts that show MCP Apps views, such as Claude and ChatGPT, the open_board tool shows the live board inside the conversation.
Check it: MCP guide: live boards
- MCP Registry
The hosted server is listed in the official MCP Registry as io.github.antonber/freero.
Check it: server.json
- Issue trackers
Board items become issues and stay in sync both ways with Jira Cloud, Jira Data Center, Linear, GitHub, Asana, monday.com, ClickUp and Trello.
Check it: Issue tracker guide
- Importing
Freero imports Miro boards, read through Miro’s API with the person’s own Miro access token, which is never stored: sticky notes, shapes, text, frames, connectors, cards, images and tags, up to 2,000 items per import; comments, documents and mind maps stay in Miro. It also imports Mural’s and Lucid’s own CSV exports, Visio (.vsdx), PowerPoint (.pptx), draw.io and Excalidraw files, Mermaid and PlantUML, CSV rows as sticky notes or cards, and images and PDFs.

- Integrations
51 integrations in all, among them Slack, Microsoft Teams, Discord, Google Chat and Mattermost for chat, and n8n, Make, Zapier and Power Automate for automation, besides the REST API and signed webhooks.
Check it: Integrations
- Built-in AI
Freero has no model of its own. Its built-in AI is off until the server’s operator or a workspace admin connects a provider: Anthropic, OpenAI or any OpenAI-compatible endpoint, including one you run yourself.
Check it: AI guide
- Languages
The interface is available in 10 languages: English, German, French, Spanish, Portuguese (Brazil), Japanese, Korean, Simplified Chinese, Arabic and Hebrew. The translations are machine-made and not yet reviewed by people.
Check it: Interface languages
- Templates
586 built-in templates, each with its own page: retrospectives, planning, workshops, diagrams, strategy and more.
Check it: Templates
- Guests
People with a share link can join a board as guests without an account, to view and comment, if the board’s workspace allows public links.
Check it: Architecture: guests
- Hosted service
The hosted Freero service stores data with its hosting provider in the United States, in one region; a self-hosted server keeps it wherever you run it. Neither the hosted service nor the software holds a SOC 2 or ISO 27001 certification yet.
Check it: Security overview
- Operator
The hosted service at https://freero.app/ is operated by Kaiten Gaming LLC.
Check it: Terms of service
- Source code
The source code, issues and documentation are public at https://github.com/antonber/freero.
