Pricing	Pay per token — model-dependent	Free (limited) + $10/mo Pro + $19/mo Business	Free + included with Creative Cloud	Free + $20/mo
Best for	Developers experimenting across models. Apps that want fallback logic.	Teams with GitHub already. Devs who don't want to change IDEs.	Anyone in Creative Cloud. Brands that need copyright clarity.	Frontend devs, PMs prototyping UIs, anyone on Next.js.
Strengths	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Great enterprise story Works in your existing IDE Chat + autocomplete	Trained on licensed content — commercially safe Generative Fill in Photoshop is incredible Native to Adobe ecosystem	Ships working React + Tailwind code Shadcn/ui native One-click deploy to Vercel
Weaknesses	Slight markup over direct API Some provider features not exposed	Less agentic than Cursor/Claude Code Model quality varies	Aesthetic ceiling below Midjourney Tied to Adobe subscription	Best for shadcn stack Iterating can be fiddly
Kai's verdict	S-tier for model-shopping. I use this for every prototype before committing.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier inside Photoshop (Generative Fill). B-tier standalone.	S-tier. If you're on Vercel/shadcn, this is cheating.
