The AI app builder space is heating up. Three tools dominate the conversation: Uje Digital, Lovable, and Bolt. We tested all three head-to-head to help you decide.
Pricing
| Builder | Free Tier | Pro Plan |
|---------|-----------|----------|
| **Uje Digital** | 3 generations/day | $12/mo |
| **Lovable** | No free tier | $25/mo |
| **Bolt** | Limited free | $20/mo |
Uje Digital is the most affordable option at every tier. It also offers the most generous free tier — 3 full generations per day with no credit card required.
Full-Stack Capabilities
This is where the differences really show:
- **Uje Digital** generates React + TypeScript frontends with Supabase for the database, auth, and storage. It creates real schemas, row-level security policies, and API endpoints.
- **Lovable** also supports Supabase but doesn't include a visual editor for post-generation tweaks.
- **Bolt** focuses on frontend generation. It doesn't generate database schemas or auth flows out of the box.
If you need a full-stack app (not just a landing page), Uje Digital and Lovable are your best options.
Code Quality
We exported projects from all three tools and reviewed the code:
- **Uje Digital**: Clean component structure, proper TypeScript types, sensible naming. The exported project runs with `npm install && npm run dev` — no cleanup needed.
- **Lovable**: Good code quality, similar to Uje Digital. Slightly more verbose in some areas.
- **Bolt**: Decent for simple projects but tends to generate monolithic files for complex apps.
All three produce code you'd be comfortable pushing to production.
Visual Editor
Only Uje Digital offers a visual editor that lets you click on any element and edit text, colors, spacing, and layout without writing code. Lovable and Bolt require you to use chat-based prompts for all changes.
For non-technical founders or designers, this is a game-changer.
Deployment
All three offer one-click deployment:
- **Uje Digital**: Deploys to `.ujedigital.com` with custom domain support
- **Lovable**: Deploys to Lovable's hosting
- **Bolt**: Deploys via third-party integrations
Uje Digital and Lovable have the smoothest deploy experience.
Our Verdict
**Choose Uje Digital** if you want the best value, full-stack generation with a database, and a visual editor. It's the most complete package at the lowest price.
**Choose Lovable** if you're already invested in their ecosystem and don't mind paying more.
**Choose Bolt** if you only need frontend components and don't need database integration.
For most developers and founders building real products, Uje Digital offers the best combination of price, features, and code quality in 2025.
