Mindoo Vega Mind map and Kanban in one embedded app
Haven free beta Data sovereignty
A secure workspace for your team. A private database for your apps.
Haven is a calm, collaborative workspace where your team works with notes, files, apps, and data - encrypted by default and installable on any device. It runs on MindooDB, an open-source, local-first sync database you can run on your own servers, in your own jurisdiction; the server only ever sees ciphertext. Real data sovereignty, without giving up real-time collaboration.
Why Haven
Five things that set Haven apart
Secure by default
End-to-end encrypted
Client-side keys, no plaintext on the server. Apps only see what you explicitly share. Fine-grained access control governs who can create, change or delete documents - enforced cryptographically, even offline.
Collaborative
Multi-user by design
Automerge-based merges, shared tenants, and a guided onboarding flow for bringing teams in.
Cross-platform
Installable everywhere
Runs as a PWA on iOS, Android, and desktop. Add multiple instances for work, personal, and demos.
Local-first
Works without network
Full local use with built-in backup and flexible push-only, pull-only, or bidirectional sync.
Extensible
Real app platform
Build apps with the MindooDB App SDK or have an AI generate them from the published context files.
In practice
From three orgs into one private workspace
When buyer, seller, and counsel work on the same confidential deal, each side keeps its own tenant. Haven brings the shared documents, Q&A, and closing tasks into one workspace - while the server only ever sees ciphertext, and every change becomes a signed node in a tamper-evident DAG.

A relaxed deep-dive into how Haven turns MindooDB into a browser-based workspace: end-to-end encrypted data with keys that never leave your device, local replicas for fast offline work, CRDT-based merging with a tamper-evident change history, strictly separated multi-tenant workspaces, custom apps, and virtual views that combine data across contexts. An entertaining and accessible introduction to the platform.
One surface for daily work
Your workspace, your way
Pages, Chicklets, and groups let you arrange databases, applications, notes, web content, and media exactly the way your team thinks. Haven becomes the calm home screen for your encrypted data.
- Multiple workspace pages reorderable like tabs, plus an All page for a full overview.
- Draggable, resizable tiles for databases, apps, notes, web, media, and Mermaid diagrams.
- Search by database, tenant, tag, or server so nothing gets lost.
- Database browser with CRUD, revision compare, and drag-and-drop file attachments.
- Rich file preview for Office, images, audio, and video - MP4 even transmuxed on the fly.
See it in action
A real workspace, ready for everyday work
Haven is not a concept mockup. It is a working product that already brings together navigation, workspace organization, search, database access, and local-first workflows in the browser.

Build on Haven
A real app platform, not just a launcher
Applications can run embedded in the Haven grid or in their own tab, access selected databases and views, and ship as either externally hosted web apps or Haven-hosted bundles served offline by the service worker.
- MindooDB App SDK with launch context, live events, documents, attachments, and Virtual Views.
- Capability-based security - Haven decides what every app can see and do.
- Online or offline - hosted bundles run even when the network is gone.
- Eight apps - three first-party productivity apps you install from Haven (Mindoo Vega, for mind mapping and Kanban task tracking with full-text search, Mindoo TodoManager, for team todos, and Mindoo Teacher's Desk, a complete digital workspace for teachers), three open-source collaborative editors that demonstrate the SDK's granular patch APIs (Mindoo TeamEdit, a collaborative markdown editor with character-level merging, Mindoo TeamGrid, a collaborative spreadsheet with around 280 Excel-compatible formulas, charts, XLSX round-trip, and Virtual View Sheets that pull data from cross-tenant Haven views into ordinary worksheets, and Mindoo TeamSketchbook, a collaborative multi-page hand-drawing sketch book with paper styles and stroke-level merging), a beautiful responsive weather tile (Mindoo Weather) that adapts to the tile size and showcases the SDK's UX surface, and the open-source MindooDB App SDK example to fork as the starting point for your own app.
- Build with AI - feed /llms-full.txt and the example repo to a coding agent and let it generate apps.
TodoManager Light and dark mode team task boards
Mindoo TeamEdit Collaborative markdown editor with character-level merging
Private by design
Encrypted from the first keystroke
Haven inherits MindooDB's trust model. Data is encrypted on the client before it ever leaves the device, apps run in sandboxed iframes with granular permissions, and the DAG explorer makes collaboration auditable.
- End-to-end encryption with client-held keys and no plaintext on infrastructure.
- Sandboxed apps on separate origins; hosted bundles get an even stricter opaque-origin sandbox.
- DAG explorer turns Automerge merges into a navigable, auditable history.
- Flexible sync - push-only, pull-only, or bidirectional per setup, and per database you can choose whether to transfer documents plus attachments or documents only for leaner, faster syncs.
- Built-in backup of in-browser data, plus Virtual Views as a secure analytical layer.
Where your data lives
Local, demo, or your own server
Haven Community works in three topologies. Choose the one that matches your workflow - you can move between them without changing clients.
Local only
Fully in your browser
Create tenants and databases entirely offline. No server, no sync - ideal for personal use, drafts, and offline demos.
Mindoo demo server
Try team features
Push a local tenant to the hosted demo server and invite real collaborators. Demo data is wiped periodically - it is for evaluation, not production.
Self-hosted
Your own server
Point Haven at a MindooDB server you run. See README-server.md for setup.
Two ways to run Haven
Community or Enterprise
Haven Community
Free beta The Haven PWA at haven.mindoodb.com. Free to use today, full local use, optional demo server, and self-hosting against your own MindooDB server.
Haven Enterprise
Commercial Custom branding, managed UI and workspaces, in-house app store, workspace roaming, automatic backup, inline attachment editing, and more - from Mindoo GmbH.

MindooDB on crazy hardware, part three - a server inside the Wi-Fi router
First an emulated x86_64 VM on an iPhone, then an Orange Pi Zero 3W with eight cores and 6 GB of RAM. This time the host is the box that was already in the room doing another job: a GL.iNet Flint 2 AX6000 Wi-Fi router - four ARM64 cores, 1 GB of RAM, 8 GB of eMMC and OpenWrt. It was the bumpiest setup of the three, and both potholes were OpenWrt's: Docker's bridge DNS could not resolve the npm registry during the build, and nftables would not hairpin the published port afterwards. Both are now handled by serversetup.sh itself. After that the server minted its identity in 1661 milliseconds, and Haven pushed a Teacher's Desk tenant to the thing that hands out our Wi-Fi.

MindooDB on crazy hardware, part two - a whole server on 14 grams of Orange Pi
Last month I ran a MindooDB server inside an emulated x86_64 VM on an iPhone: 75 minutes for the Docker build, 102 seconds for one identity. The hardware actually meant for the job has now arrived - an Orange Pi Zero 3W, 65 x 32 mm, 14 grams, eight ARM64 cores and 6 GB of RAM, $85 from Amazon and ten days lost somewhere between Dallas and Cologne. Same repository, same serversetup.sh, no changes for ARM64: the Docker build took 137.6 seconds and the server identity 649 milliseconds. Then Haven pushed a Teacher's Desk tenant to it over Wi-Fi and synced several thousand encrypted entries to a board that fits in a shirt pocket.

Mindoo Vega grows up - Gantt charts, a real spreadsheet, and the project as it was last month
Vega used to be a mind map with a Kanban board attached. It now carries a Gantt chart you can drag dates around in, a full Excel-compatible spreadsheet - the TeamGrid engine, 280 formulas, column, bar, line and pie charts - that mirrors your project nodes into cells and writes your edits back to them, and an XLSX export anyone can open. MindooDB's time travel turns into project reporting: open the plan as it stood at the kickoff, or put two dates side by side in a comparison spreadsheet where XLOOKUP has already paired the old and the new rows and the delta columns are written for you. Plus poster printing across any number of sheets with glue strips, links between nodes across maps and tenants, a dockable properties sidebar with Markdown and Mermaid, a node icon library, and better layouting. There is a new site for all of it at mindoo-vega.com.
