BlueWillow
A recognisable free-art brand that is now mostly a redirect into LimeWire's image studio, which is fine if you just want quick images at no cost. The catch is that the product you sign up for is not the one on the label, and BlueWillow's page documents none of the limits or rights that apply.
Pros
- No payment required to produce first images
- Prompt box on the landing page starts the flow immediately
- Active community channels on Discord and Reddit
Cons
- Generation, accounts and limits all move to LimeWire
- No pricing, quota or rights information published on the site
- No API and no self-hosting path
