The Problem with
Most AI App Builders

Most tools trap you in closed systems, limit you to one model, and stop at prototypes, leaving you with brittle code, rising costs, and no real path to production.

Lock-in everywhere

Proprietary engines, opaque credit pricing, and no freedom to choose the best model for each task.

Easy to Demo. Hard to Scale.

Great-looking demos that break when you try to deploy, scale, or maintain them.

Too abstract or too raw

Either everything is hidden behind magic, or you’re dropped into a bare IDE with no structure.

Connect to Any LLM
Zero Lock-In

PromptXL gives you full freedom to choose the LLM that fits your needs, budget, and performance goals.

Connect Your Own API Keys

Use Claude, Gemini, or any future model with your keys. No markup, no credit lock-in

Generate & Improve Code

Gemini for UI, Claude for logic β€” swap models anytime without breaking your app.

Ask Questions

Your app builder becomes your coding partner. Answer questions, explain logic and spot mistakes.

Freedom to Build
in any model or framework
