Stablecog

Free, open-source AI image generator with text-to-image, image-to-image, upscaling, and a public API.

67/100MonitorFree · from $10/monthFreemium

Stablecog is a good fit if you want a low-cost, browser-based generator built on open-source models — FLUX.1, Stable Diffusion, Kandinsky — with a public API and image upscaling you can call programmatically. The free tier's 20 images/day with slow generation covers daily experimentation; the $10/month Starter tier is where private images and commercial use kick in. Pick Midjourney or Adobe Firefly instead if you need advanced editing or collaboration, or if you're chasing top-tier aesthetic polish. The 2,000–12,000 image monthly caps and no-rollover credits mean heavy generators should watch overages rather than assume unlimited output.

Skip it if

Skip Stablecog if you need team collaboration, advanced editing like inpainting or layered edits, or unlimited output — the plans cap at 12,000 images/month and the free tier limits you to 20 public, personal-use images per day.

The 30-second take
Biggest gripe

Credits don't roll over — they reset every month on your billing date, so any unused images are simply lost.

Price reality

Stablecog sits in the budget tier of AI image generators. Starter at $10/month undercuts most subscription rivals for commercial use, and Pro at $25/month is priced similarly to single-seat creative tools but with far lower monthly caps. Choose Starter or Pro if you're a solo creator or small shop generating a few thousand images a month; step to Ultimate ($50/month, 12,000 images) before assuming you need an enterprise contract. If you need team seats and shared workspaces, expect to look at a

About Stablecog

FreemiumBeginner-friendlyAPI availableWeb · API

Stablecog is a free, open-source AI image generation platform that turns text descriptions or input images into art in seconds. You describe anything — in thousands of styles — or hand it an input image and generate variations based on it. The web interface requires no app install, so you can generate from any browser. It supports multiple open-source models, including Stable Diffusion, FLUX.1, and Kandinsky, giving you a range of artistic options. The free tier gives you 20 images per day with slow generation, a maximum of 1 image per generation, no parallel generations, and public images for personal use only. Paid plans (Starter at $10/month, Pro at $25/month, Ultimate at $50/month) unlock fast generation, private images, commercial use, higher monthly quotas (2,000 / 6,000 / 12,000 images), up to 4 images per generation, and 2–4 parallel generations. Credits do not roll over — they reset each month on your billing date — and optional credit top-ups require an active subscription. Developers can use the public API, which added an image upscaling endpoint for programmatic resolution increases. The interface also includes parallel generation, image upscaling, semantic image search, and generation history to manage your work. There's no built-in team collaboration or advanced editing suite. It's aimed at hobbyists, content creators, and developers who want a low-cost, straightforward image generator with open-source models and a transparent API.

Behind the Verdict

Stablecog's pitch is narrow and clear: generate images from text or an input image, on open-source models, without paying much. That honesty is its strength. The web interface works from any browser — no app to install — and its model lineup (Stable Diffusion, FLUX.1, Kandinsky) covers a range of styles from photorealism to illustration. The free tier is genuinely usable: 20 images per day with slow generation, max 1 image per generation, no parallel generations, and public images for personal use only. Where it gets interesting for buyers is the transition to paid: Starter at $10/month flips generation to fast, allows up to 4 images per generation, 2 parallel generations, private images, and commercial use, for a 2,000 images/month quota. Pro ($25/month, 6,000 images) goes to 3 parallel generations; Ultimate ($50/month, 12,000 images) goes to 4. The API is a real differentiator for a tool at this price. The docs cover generation, upscaling, and billing, and the upscaling endpoint lets you raise generated resolution programmatically instead of doing it by hand. Semantic image search and generation history make it easier to find and reuse past work. Where it doesn't fit: there's no team workspace, no shared libraries, and no advanced editing suite. Professional designers who need inpainting, layered edits, or precise style control will hit the edge quickly. The free plan's public-images and personal-use-only rules rule it out for anything commercial without a subscription. Credits also don't roll over — they reset monthly on your billing date — so misjudging a month's output means losing the difference. Credit top-ups require an active subscription, so there's no dipping in for a one-off batch after you cancel. For solo creators and small businesses who want a flexible, transparent generator with a documented API, those are manageable trade-offs. For studios and larger teams, they're disqualifying.

Real-world workflow fit

Concrete scenarios for the personas Stablecog actually fits — and what changes day-one when you adopt it.

Solo content creator

You need a week of social graphics fast. You open Stablecog in a browser, type a prompt like 'majestic cat, psychedelic, violet tones', generate up to 4 images at once on the Starter plan, pick the keeper, and download it for commercial use.

Outcome: A week of on-brand visuals produced in a single sitting, at $10/month with private images and commercial rights.

Indie app developer

You wire your app to Stablecog's public API using the docs, then call the upscaling endpoint on generated images before serving them to end users.

Outcome: Image generation and resolution upscaling handled programmatically, without building your own model infrastructure.

Hobbyist exploring AI art

You sign up free and generate 20 images per day with slow generation, testing prompts across Stable Diffusion, FLUX.1, and Kandinsky, and browsing your generation history to compare styles.

Outcome: Free experimentation with multiple open-source models and no commitment, accepting public images and personal-use-only terms.

Limitations

  • The free plan caps you at 20 images per day with slow generation, max 1 image per generation, no parallel generations, and personal use only — and those images are public.
  • Paid plans cap at 2,000 / 6,000 / 12,000 images per month with fast generation and up to 4 images per generation.
  • Credits do not roll over between months: they reset every month on your billing date, so unused credits are lost.
  • There are no credit top-ups on the free plan, and buying credits requires an active subscription.

Adds fast generation, up to 4 images per generation, 2 parallel generations, private images, and commercial use for 2,000 images/month.

Pro

$25/month

Ideal for

Higher-volume solo creators and small shops producing around 6,000 images a month.

What this tier adds

Raises the monthly quota to 6,000 images and adds a third parallel generation slot over Starter.

Ultimate

$50/month

Ideal for

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • Credits don't roll over — they reset every month on your billing date, so any unused images are simply lost.
  • Credit top-ups require an active subscription, so you can't buy a one-off batch of images after you cancel.
  • Commercial use and private images are locked behind the paid plans; free-plan images are public and personal-use only.
  • Parallel generation is capped per tier (0 on Free, 2 on Starter, 3 on Pro, 4 on Ultimate), so teams running batch jobs hit the ceiling fast.

Migrating out
  • ↗To Midjourney: move if you need higher-end aesthetic output and community features rather than an API-first generator.
  • ↗To Adobe Firefly: move if you need advanced editing and tighter integration with creative-suite workflows.
  • ↗To a self-hosted Stable Diffusion setup: move if you need full control over models and unlimited generation without monthly caps.
