First public release. Pumkin is a local-first IDE for building and running AI agents against your own Ollama models — no cloud inference, no API keys, no per-token cost. Everything runs on your machine.
Free and open source under the MIT license.
Install (Windows)
- Download Pumkin_0.0.1_x64-setup.exe below.
- Run it. Windows SmartScreen may warn about an unknown publisher (the build isn't code-signed yet) — click More info → Run anyway.
- Make sure Ollama is running, then launch Pumkin.
Requirements: Windows 10/11 64-bit, 8 GB RAM, and Ollama with a tool-capable model pulled. On 8 GB, start with llama3.2:3b.
What's in it
- Build named agents with specific tools and a system prompt.
- Run them against your local Ollama models and watch the full event stream live (model responses, tool calls, results).
- Connect your own tools over MCP (Model Context Protocol) — any MCP server works.
- Approval gate: require an agent to ask before any tool call, with the exact call and arguments shown first.
- Local SQLite storage for agents, runs, and history. Nothing leaves your machine.
- Use it from the web UI or the CLI.
Known limitations
- Windows only for now; macOS and Linux are next.
- Not code-signed yet (hence the SmartScreen prompt).
- Early-stage (v0.x) — expect rough edges. Bug reports and PRs welcome.
