**A self-improving agent workspace. You bring the keys and the sandbox. The agent builds the rest.**

Fleet Pi is a **meta-harness** — a complete, self-hosted agent workspace built on Pi. It ships as a working web app with a chat UI, Agent and Plan modes, durable workspace memory, and sandboxed execution. But unlike a traditional agent tool, Fleet Pi is designed to be **self-improving**: the agent writes its own skills, registers its own prompts, evaluates its own output, and adapts to you over time.
The agent is simultaneously the worker and the architect of its own environment. Two users with Fleet Pi will have completely different systems after a few sessions — because the system _became_ what they needed it to be.
agent-workspace/ is Fleet Pi's durable adaptive layer: its memory, plans, skills, evals, and artifacts stay with the project as reviewable files.
Why Fleet Pi?
| Problem | Fleet Pi's approach |
| ---------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------- |
| **SaaS lock-in** — your agent lives in their cloud, your data is proprietary | **Self-hosted, BYOK, BYO sandbox** — your keys, your compute, your Git repo |
| **Fixed feature set** — you're stuck on the vendor's roadmap | **Self-improving** — the agent creates its own skills, prompts, and tools |
| **No audit trail** — opaque logs you can't diff or review | **Git-native provenance** — every file change is reviewable, every decision is traceable |
| **No isolation** — shared tenants, no per-user sandboxing | **Per-user Daytona sandboxes** with durable volumes and credential isolation |
| **DIY complexity** — frameworks that give you parts, not a working system | **Ship as a working app** — clone, install, run, and the agent adapts |
Quick start
**Prerequisites:** Node.js 22+, pnpm (via Corepack), and an LLM provider key.
