v0.8 · free and open source · Apache 2.0

The self‑hosted wiki built for people and AI agents.

Write, keep and share your team's knowledge on your own server. Connect any AI assistant through MCP, and see every change it makes.

  • Every change an agent makes is recorded and reversible. A new version in the page's history, logged against its token.
  • Assistants see only what you let them. A token acts as its owner; a read-only one can't change anything.
  • Restore, and undo the restore. Tested backups, from the admin page.

Beta Tesria is new: carefully built and heavily tested, but not yet by many people. Keep backups, and tell us what breaks.

      Private access with Tailscale

      Reach your wiki from anywhere, or invite friends, with no port opened to the internet. Tesria has Tailscale built in, off until you turn it on.

      New to Tailscale? It's a secure private network (a mesh VPN built on WireGuard). Turning it on costs nothing in Tesria, and Tailscale's free Personal plan covers most homes and small groups.

        Tailscale and the Tailscale logo are trademarks of Tailscale Inc. Tesria is not affiliated with or endorsed by Tailscale.

        The admin dashboard

        • Answers to common questions: Is everything all right, and is anyone using this? One screen answers both
        • People, content, usage and backup health, with the most viewed pages and most active editors

        Accounts and security

        • Two-factor sign-in, recovery codes, lockouts, and single sign-on through OpenID Connect (in beta)
        • A tamper-evident audit log, security alerts you act on, and a dependency check against OSV.dev that runs only when you press it

        Share

        The right people, the right pages.

        09

        Sharing and publishing

        • Roles, groups, space permissions and page restrictions; public spaces anyone can read
        • Export a space as a static website, a PDF, or a wiki pack that imports into another Tesria
        • You decide what leaves: public spaces take two switches, and any export format can be turned off per space, for everyone and through the API
        Features →
        10

        Make it your own

        • Your own name, logo and colors on your instance, and in what you export
        • Everyone picks light, dark or their system's setting, and an accent

        This is the real setting: it recolors the whole site, and the docs.

        Features →

        Automate

        Agents that work with you.

        11

        MCP, API and webhooks

        • A built-in MCP server: Claude, Cursor or any MCP client can read, search, create and update pages
        • An assistant sees only what its token's owner may, and a read-only token can't change anything
        • A REST API with an OpenAPI reference, and webhooks when pages change
        Features →
        12

        Every change recorded and reversible

        • Every change an agent makes is a new version in the page's history, logged against its token
        • Open the page and the change is highlighted, with Accept all and Reject all
        Planned for 1.0: review mode, to approve an agent's changes before they go live.
        Features →
        Who it's for

        From one person to a whole company.

        People who run infrastructure

        Lock-in, compliance, and where the data lives.

        Your own server, ready-made Docker images, tested backups with undo, and private access through Tailscale.

        Developers using AI assistants

        Giving an assistant the team's docs without giving it the keys.

        An MCP server limited to what a token's owner may see, read-only tokens, and every change recorded and reversible.

        Team leads

        Docs that go stale, and knowing what changed and who changed it.

        Real-time editing, a full history of every page, and agents that help keep pages current.

        Start on a laptop, grow to a team, run it for an organization that keeps its own data. Slide to see what changes.

        How Tesria scales →
        Proof, not a promise

        The docs are a Tesria space.

        We wrote the documentation in Tesria and exported it as a static website, with its page tree, filter and themes. Open it, and you're reading Tesria.
