Nova Image Studio
tianjiangqiji
Self-hosted, bring-your-own-API image-generation workbench with an infinite canvas and PWA.
What is Nova Image Studio?
A self-hosted TypeScript web workbench that front-ends external image models you configure with your own API keys and endpoints - it does not run models itself. It offers five modes (text-to-image, image-to-image, an AI agent chat, reverse-prompt, and GIF generation), a real-time task queue over WebSocket with HTTP fallback, an infinite canvas, a prompt gallery, and SQLite task persistence. Installable as a PWA across desktop and mobile.
Pros & Cons
Pros
- Clean self-hosted UI over whatever image APIs you already pay for
- Infinite canvas, task queue and PWA install make it more than a thin wrapper
- SQLite persistence and per-model endpoint config give real flexibility
Cons
- Does not generate images locally - you still need external paid model APIs
- AGPL-3.0 source-disclosure obligations apply if you host a modified version
- Young (36 commits), and docs plus description are primarily in Chinese
License
AGPL-3.0 (OSI-open)
AGPL-3.0 is a genuine OSI license, but its network-copyleft clause means offering a modified hosted version obliges you to publish your changes.
When it is interesting
You want one self-hosted canvas UI in front of several commercial image APIs.
When it is too early
If you expected local or offline generation, or need an English-first, mature codebase.
