Deft

Where humans and agents work together.

Website | Self-hosting guide | Contributing

Deft is a self-hostable, open-source workspace where people and AI agents share the same chat, tasks, knowledge, calendar context, approvals, and receipts.

Instead of pasting fragments from Slack, Notion, and a task tracker into an AI chat, connect Codex, Claude, ChatGPT, or your own agent to the work record your team already uses.

The core loop

1. Work happens in context. People discuss an issue in chat, update a task, write a note, or record a decision.
2. An agent reads the same workspace. Defty, an agent employee, or a personal MCP client can retrieve the relevant messages, tasks, wiki pages, people, and calendar context.
3. Writes stay governed. Risky changes are drafted first and shown as approval cards in the conversation and approval inbox.
4. The result lands in Deft. Tasks, messages, notes, wiki pages, and status changes become part of the shared record.
5. Every action leaves a receipt. The workspace records who or what acted, what changed, and where the result lives.

What ships today

A workspace people can use normally

• Real-time chat with spaces, DMs, threads, mentions, reactions, files, presence, and rich text
• Task management with Board, Table, Timeline, Calendar, Pipeline, and personal views
• Notes, company knowledge, channel memory, decisions, references, and knowledge graph views
• Native calendar events plus read-only ICS subscriptions
• Dashboard, inbox, notifications, people, teams, roles, and profile management
• Dark and light themes, desktop and mobile layouts

A work record agents can use safely

• Built-in Defty workflows for workspace questions and governed native actions
• Personal MCP access for Codex, Claude, ChatGPT, and streamable HTTP MCP clients
• Agent employees that can participate in channels, receive assignments, and use Deft tools
• Native task, message, wiki, note, calendar, member, team, and context-packet tools
• Approval tiers, trust levels, token scopes, revocation, activity history, and action receipts
• Provider-neutral AI configuration: OpenAI, Anthropic, OpenRouter, OpenAI-compatible endpoints, or local Ollama-style providers

Deft still works as a normal workspace without an AI provider key. Chat, tasks, notes, knowledge, calendar, people, and teams remain available; AI features stay disabled until a provider is configured.

An extensible workspace through Modules

Deft's workspace can also grow with the needs of a company. Modules let developers add domain-specific collections and applications while inheriting the workspace primitives that already exist, including identity, permissions, search, context and agent access.

The bundled Contacts module is the first example of this model. The goal is not to turn Deft's core into every application a company might need, but to let new capabilities live on the same shared substrate instead of becoming another disconnected system.

Product surfaces

Chat keeps the source conversation attached

Chat is both a human communication surface and part of the workspace record. Threads, structured mentions, quiet knowledge capture, and agent replies keep decisions close to their source.

Tasks turn context into accountable work

Projects support Board, Table, Timeline, Calendar, and Pipeline views, plus dependencies, subtasks, recurrence, comments, activity diffs, bulk actions, and agent-created drafts.

Knowledge becomes durable team memory

Deft separates transient conversation from durable concepts, entities, decisions, resources, procedures, preferences, and facts. Agents can ask for org-wide or channel-specific context instead of reading an undifferentiated transcript.

Connect the AI app you already use

The Connections page guides each user through the setup required by their client. Personal connections act as that user, inherit their access boundaries, expose explicit scopes, and can be revoked.

Why Deft is different

Quick start with Docker

Requirements

• Docker Desktop or Docker Engine with Compose
• A machine capable of running PostgreSQL, the API, and the web app
• Optional: an AI provider key or local model endpoint for agent features

git clone https://github.com/Maneek21/Deft.git
cd Deft
cp .env.example .env

Set the three required secrets in .env:

Then build, start, initialize, and verify the stack:

docker compose build deft init doctor smoke
docker compose up -d
docker compose run --rm init
docker compose run --rm doctor
docker compose run --rm smoke

Open http://localhost:3000. The first account creates and owns the workspace.

See docs/self-hosting.md for environment variables, HTTPS, backups, health checks, AI providers, and production operations.

Run a named preview image

Preview releases also publish an amd64 image to GHCR. Download the release
assets, copy .env.example to .env, set the required secrets and public
URLs, then run:

Choose a release whose notes identify it as AGPL-3.0-only, then set its
exact immutable tag. Historical releases through v0.2.0-preview.4 retain the
BSL 1.1 license included in those revisions; relicensing this source tree does
not retroactively change old tags or images.

export DEFT_IMAGE=ghcr.io/maneek21/deft:0.3.0-preview.2
docker compose -f docker-compose.yml -f compose.prod.yml -f compose.release.yml pull
docker compose -f docker-compose.yml -f compose.prod.yml -f compose.release.yml up -d postgres
docker compose -f docker-compose.yml -f compose.prod.yml -f compose.release.yml run --rm init
docker compose -f docker-compose.yml -f compose.prod.yml -f compose.release.yml up -d deft
docker compose -f docker-compose.yml -f compose.prod.yml -f compose.release.yml run --rm doctor

Fresh installs use init. The supported versioned upgrade baseline starts at
v0.2.0-preview.1; later releases can be applied with the backup-first
pnpm selfhost:upgrade --prod --release flow documented in the self-hosting
guide. Historical pre-preview databases are not automatically adopted.

pnpm db:push-full is for fresh installs. pnpm db:upgrade is for supported release-to-release upgrades. Do not use raw pnpm db:migrate against important data.

Local development

Requirements: Node.js 22.13+, pnpm, and PostgreSQL 16 with pgvector.

git clone https://github.com/Maneek21/Deft.git
cd Deft
pnpm install
cp .env.example .env

pnpm db:push-full
pnpm db:seed
pnpm dev

Useful development seeds:

pnpm db:seed:demo   # Testers Tomatoes demo data
pnpm db:seed:pilot  # Demo data plus pilot fixtures

Both development seeds reset the database. Never run them against a production workspace.

Project status and limitations

Deft is an alpha. It is suitable for technical evaluation, internal dogfooding, and controlled pilots. Expect breaking changes before a stable release.

Important current boundaries:

• One workspace per self-hosted deployment is the supported product contract.
• Versioned upgrades are supported from the v0.2.0-preview.1 baseline forward; older untracked alpha databases require a reviewed migration or fresh install.
• Native Google, Slack, Gmail, and GitHub OAuth integrations are not part of the current self-hosted v1 promise. Use ICS for calendar subscriptions and bring external tools through your own agent or MCP runtime.
• Agent quality depends on the configured model, scopes, workspace data, and approval policy.
• This repository is open source under GNU AGPL v3.0 only.

Security reports should follow SECURITY.md. Operational support boundaries are documented in docs/self-hosted-v1-contract.md.
