# posse
A web UI for [Anthropic Managed Agents](https://docs.anthropic.com/en/docs/agents/managed-agents).
Anthropic ships the best agent infrastructure — sandboxed environments, persistent memory, tool use, multi-agent orchestration — but no UI. You're stuck with curl and the API console.
Posse gives you the missing interface: create agents, run sessions, manage memory stores, and watch your agents work — all from a browser.
## What you get
- **Agent management** — Create, edit, archive, and version agents with different models (Sonnet, Opus, Haiku)
- **Sessions** — Start sessions, send messages, watch tool calls and code execution in real time
- **Memory stores** — Browse and edit persistent memory that agents carry across sessions
- **Environments** — Switch between execution environments with different tools and configurations
- **Multi-agent** — Run multiple agents side by side, each with their own sessions and memory
## Quick start
```bash
docker run -p 3000:3000 \
-e ANTHROPIC_API_KEY=sk-ant-... \
ghcr.io/oguzbilgic/posse:latest
```
Open [http://localhost:3000](http://localhost:3000).
## From source
```bash
git clone https://github.com/oguzbilgic/posse.git
cd posse
echo "ANTHROPIC_API_KEY=sk-ant-..." > .env.local
npm install && npm run dev
```
## How it works
Posse is a lightweight Next.js app that proxies requests to the [Anthropic API](https://docs.anthropic.com/en/docs/agents/managed-agents). Your API key stays server-side — never exposed to the browser.
The entire app is ~13k lines of TypeScript with zero backend dependencies beyond Next.js. No database, no auth layer, no state server. It reads everything from the Anthropic API and renders it.
### Stack
- Next.js 16 + React 19
- TypeScript + Tailwind CSS
- Zustand for client state
- Marked + highlight.js for markdown/code rendering
## Why
Anthropic's managed agents are powerful but invisible. You define agents in JSON, create sessions via API, and parse events from streams. It works, but you can't *see* what's happening.
With posse, you get a real workspace: watch an agent write code, see it execute bash commands, check what it stored in memory, start a new session with a different environment. The kind of feedback loop you need when building with agents.
## Status
Early. Shipping fast. Core features work — agents, sessions, chat, memory, environments. What's next:
- [ ] SSE streaming (currently polling)
- [ ] File upload / media attachments
- [ ] Session event filtering and search
- [ ] Agent skill configuration UI
- [ ] Callable agent orchestration view
