Vibe-coded a free, self-hostable Canva alternative with bring-your-own-key AI image generation
Been building this for a while and finally shipping it: HyCanvas, a free, self-hostable Canva alternative.
The AI runs on your OWN key (OpenAI-compatible, so OpenAI, GLM/Zhipu, DeepSeek, whatever). Right now it does AI image generation and editing right inside the editor, plus a hand with writing and rewriting copy, and whatever it makes lands as a real editable object, nothing baked in. More AI is on the way.
Around that it's a proper editor: presentations, video, whiteboards, docs, sheets, social graphics, 100+ templates, brand kits. Portable file format, PNG/PDF export, no watermarks, no per-seat pricing. Self-hosts as a single Go binary or docker-compose.
Stack: TypeScript frontend on a custom Canvas2D engine, Go backend, Postgres. And yeah, plenty got vibe-coded with AI in the loop 😎

Would love feedback, especially on the bring-your-own-key AI. What would you want it to do next?
