Install Pumkin
Pumkin ships as a single Windows installer — no dependencies to chase, the runtime it needs is bundled in. It’s free and open source; grab the latest build from GitHub Releases.
1. Download
Head to the releases page and download the latest installer. You’ll get a file named like:
Pumkin_0.0.1_x64-setup.exeEvery release lists its installer under Assets. If a download fails partway, just grab it again.
2. Run the installer
Double-click the .exe. Windows will install Pumkin and drop a shortcut in your Start menu and on your desktop.
Getting past the SmartScreen warning
The first time you run it, Windows SmartScreen may show a blue “Windows protected your PC” dialog saying the publisher is unknown. This is expected — it appears for any app that isn’t yet code-signed with a paid certificate, not a sign anything’s wrong.
To proceed:
- Click More info
- Click Run anyway
Why the warning? Code-signing certificates cost a few hundred dollars a year, and removing this prompt is on the roadmap. Until then, the click-through is harmless. You can verify exactly what you’re running — the full source is on GitHub.
3. First launch
Open Pumkin from the Start menu or desktop shortcut. On first launch it starts its local server and checks that it can reach Ollama.
Make sure Ollama is running before or shortly after you launch (on Windows it auto-starts, so it usually already is). If Pumkin can’t find any models, it’s almost always because Ollama isn’t running or you haven’t pulled a model yet — go back to Install Ollama & models.
Where Pumkin keeps its files
Pumkin installs and stores its data under your local app data folder:
%LOCALAPPDATA%\Pumkin\That’s where the app lives and where your local database (runs, messages, tool history) is kept. Logs live here too, which matters if you ever need to debug something — see Troubleshooting.
You’re installed. Next: Your first agent →
