SpriteLab vs Retro Diffusion
Retro Diffusion makes pixel-art-specific AI models. Its official documentation lists sprites, animations, tilesets (including Wang tilesets and seamless tiles) and low-poly 3D models via a website and HTTP API, a hosted MCP server, and a separate Aseprite extension sold as a one-time purchase. Pricing on the web/API side is prepaid and pay-per-generation. SpriteLab covers 12 art styles (not just pixel art) on a monthly plan, but has no API, MCP or tileset autotiling.

Which should you choose?
Choose Retro Diffusion if…

- You want an API or MCP server to generate from code or an AI assistant.
- You want an Aseprite extension you buy once and run locally.
- You prefer paying per generation with no subscription.
Choose SpriteLab if…
- You want non-pixel styles too — hand painted, anime, chibi, vector, cartoon, realistic.

- You want sprites, animation, tiles and icons organised in projects with ZIP export.
- You want to try a few generations before creating an account.

Common questions
Is SpriteLab a Retro Diffusion alternative?
+
Partly. Both make real pixel art, but Retro Diffusion is pixel-art-only with an API, MCP, Wang tilesets and an Aseprite extension, while SpriteLab covers 12 art styles on a monthly plan and focuses on prompt-to-sprite plus animation.
Is the Retro Diffusion Aseprite extension the same as their website?
+
No. Retro Diffusion's own itch.io page says the extension and website are different tools using different models; the extension runs locally.
