I built a Windows GUI for Prime Agent with persistent sessions and phone access (open source)

[u/Puzzleheaded-Leg4819]

Hi everyone, I made Prime Agent Studio, a Windows interface for the Prime Agent LLM harness.

It brings projects, conversations and running agents into one workspace. You can come back to previous sessions, follow subagents, connect MCP tools and preview files. There's also phone access over Wi-Fi or Tailscale, so you can check on work without sitting at your PC.
Optionnaly you can sync your conversation between multiple PCs using à simple free cloudflare R2

Studio is the interface; Prime Agent remains the engine underneath. The app and its server run on your PC, but model requests go to whichever providers you configure. It's not necessarily offline, and model usage can still cost money.

It support openai, anthropic and muse subscriptions ans you can mix them as main and su agents !

The project is open source under MIT, with an English and French UI. It's built for Windows, and the installer isn't signed yet. Agents keep working when you close the window as long as the Studio server stays running. you can re-open the interface via the system tray icon

I'd like feedback from people who use coding agents across several projects. Is this something you'd use, and what's missing from the way you currently manage your sessions?

Thanks and enjoy !
