Download · Hobby edition
The complete editor, free, on your desktop.
Hobby is PIES Studio running entirely on your own machine, for macOS, Windows and Linux, with PIES Private AI on board: build your products with AI that runs on your computer, nothing to pay, nothing leaves your desk. No server, works offline. Downloading needs a free PIES account, so we can tell you about updates.
What's in Hobby
- The complete PIES Studio editor, on your own machine
- Unlimited local apps and local builds, with a real database and build toolchain inside
- All 35 industry templates, sample data and agent packs, offline
- Visual builder, step catalogue, processes, document templates and PDF
- PIES Private AI Micro: AI that runs on your machine, nothing to pay, nothing leaves your desk
- Mobile app generation and phone-frame preview
- Code export: download the source of your apps and run them without PIES
- Works offline. No server, no telemetry, nothing phoning home
Code export is free: download the source of anything you build. Hobby locks hosting from the Studio, back-end stack choice, mobile publishing, teams and boards, Git push, hosted agents, cloud storage and full governance. Each shows a padlock and what unlocks it. Compare editions →

Windows: The Windows installer isn't code-signed yet. Windows may show 'Windows protected your PC' — click More info → Run anyway. Check the file with the SHA-256 on the release page.
Every installer has a SHA-256 checksum on the PIES Studio 1.9 release page (build 1.9.62). Your free account gives you the installer for your platform, release notes and update notices. Hobby itself runs on your desktop with no server and works offline.
