Stable Diffusion
Open-source AI image models you can self-host, with deep customization and no per-image fee.
Stable Diffusion is the open-source backbone of AI imagery — unbeatable for control and cost if you’re willing to get technical.
What it is
A family of open-weight image models (SDXL, SD 3.5) you can download and run on your own hardware, plus a paid hosted API from Stability AI. The real power is the ecosystem: LoRAs, ControlNet and endless community tooling.
Pricing
Free to self-host (Community License is free for organizations under $1M revenue); the hosted API is credit-based from roughly $0.03 per image, with a membership around $20/month.
The rating picture
Formal reviews are sparse and split, as you’d expect for an open project — G2 4.6 and Product Hunt 4.9 from developers, but a low Trustpilot (often reflecting unaffiliated third-party “Stable Diffusion” websites, not Stability AI). With so few reviews, we show the breakdown rather than a headline.
Verdict
For developers and privacy-conscious teams who want total control and no per-image cost, nothing else compares. Casual users will find hosted tools far easier.
