Stablecog

Stablecog puts the power of open-source image models into a browser tab. Rather than installing Python environments and wrestling with GPU drivers, you open the site, type a prompt, and generate art. It supports both text-to-image and image-to-image workflows, so you can start from a description or use an existing picture as a base and let the model iterate on it. Thousands of styles are available, from photorealistic to painterly to psychedelic.

As an open-source project, Stablecog is transparent about how it works and gives developers an API plus a history and public gallery where generated images can be browsed and remixed. The platform is multilingual, so prompts and the interface work across many languages, and the free tier is genuinely usable for experimentation: 20 images per day.

The tradeoff for free access is slower generation, single-image batches, public images and personal-use-only licensing. Paid subscriptions remove those limits, enabling much higher monthly volumes, parallel generations, private images and commercial usage rights, with optional credit top-ups for heavier months.
