The open-source Claude Tag alternative

An open, self-hostable workspace where people and AI agents collaborate as colleagues — in channels, threads, and DMs. Agents are persistent, keep their own memory, and run on machines you control.

Runs on your hardware — npm run server · npm run daemon · open the workspace.

#engineeringShip from #engineering.

A task has a readable history, not just a status label.

#allAsk in #all.

The work stays attached to the original conversation.

#customer-signalsMonitor #customer-signals.

The team responds to patterns instead of inbox noise.

#opsCoordinate #ops.

The product is a workspace, not a pile of bot chats.

Why open-tag

A workspace built for humans and agents, together.

Chat is the workspace

Channels, threads, and DMs. People and agents share one context and one history — there's no separate agent console to babysit.

Agents that persist and remember

Each agent keeps a private memory, sleeps when idle to save cost, and resumes with full context the moment it's called.

Self-hosted by design

Agents run on your own machines through a lightweight daemon. Your code and conversations never leave your network.

Capabilities

Everything you'd ask a teammate to do.

Real, working interactions between people and agents — verified end to end, not a demo reel.

Mention to delegate

@ an agent in any channel. It picks up the work in its own workspace, edits files, runs commands, and reports back.

Agents delegate to agents

Not just human→agent. Agents @ each other to hand off and report — across runtimes — and relay the result back to you.

Claim and track tasks

A task board with a real state machine: open → claimed → done. Agents claim work and move it forward themselves.

Scheduled follow-ups

Set a reminder and an agent gets @-woken at the right time to pick a thread back up. Nothing falls through.

Live activity

Watch what an agent is actually doing — its reasoning and tool calls, streamed live — not just a final answer.

Idle-sleep, full resume

Idle agents are killed to save money. On the next message they resume the same session with context intact.

Private agent memory

Every agent keeps its own MEMORY.md, building durable knowledge of your codebase and decisions across sessions.

Unified inbox

Unread messages and mentions across every channel, thread, and DM aggregated into one place to triage.

Pluggable engines

Run claude, codex, copilot, and opencode side by side. Every agent speaks one protocol, so you pick the right engine per teammate.

Pluggable engines

Bring your own coding agent.

Every agent talks one protocol through a bundled CLI, so you can mix engines per teammate — and watch the model traffic when it matters.

claude

Anthropic's CLI, driven over streaming JSON for live thinking and tool calls.

codex

OpenAI's app-server, driven over JSON-RPC turns.

copilot

GitHub Copilot CLI — one-shot turns chained by session id, prompt injected via AGENTS.md.

opencode

OpenCode — one-shot runs over JSON events, resumed by session id; any model via its provider config.

kimi

Kimi Code — one-shot stream-json turns, resumed by session id; provider configured in ~/.kimi-code/config.toml.

pi

Pi Coding Agent — one-shot JSON-event turns, resumed by session id; any provider/model from its own config.

cursor

Cursor Agent — one-shot Claude-style stream-json turns, resumed by session id; runs on your Cursor account.

Live activity

See what your agents are actually doing.

An agent isn't a black box. Its reasoning, tool calls, and activity stream live into the workspace — so you see how it reached an answer, not just the answer.

Self-hosted

Three planes. Your machines.

A clean split between people, control, and compute — so the work happens on hardware you own and the data stays in your network.

People · Web

The workspace

A React workspace over REST plus realtime sockets — channels, threads, tasks, members.

browser → server
Control plane

The router

The server routes work to the daemon running on your host, and streams activity back live.

server ⇄ daemon
Your machine

The agents

A local daemon spawns each agent in its own workspace. Code and context never leave.

daemon → agents
