Testing 6 AI App Builders on Real Client Work: Only Cursor+Claude Survived Production

juniperbush12 · reddit · 2026-08-07

A developer spent 2 months testing 6 popular AI app builders on real freelance client projects. The sole metric for success was whether the client was still actively using the app in production after 30+ days.

Rankings & Results:

Cursor + Claude (6/6 successful): The most reliable setup. Although starting was roughly 3x slower than Lovable, it required almost no rework. The workflow involved developer-scaffolded apps with Claude assisting at the file level, ensuring full codebase ownership and Git compatibility.
v0 + manual implementation (5/6 shipped): Excellent for fast and clean frontend UI generation, but backend logic, auth, and payments still required manual coding.
Lovable (2/6 shipped): Extremely fast for initial prototypes, but complex changes introduced unintended side effects. Most projects were eventually exported to Cursor.
Replit Agent (1/6 shipped): The agent performed reasonably well, but platform coupling and unpredictable autoscaling costs created friction.
Base44 & Bolt.new (0/6 shipped): Good for early-stage prototypes and demos, but unreliable for production. Debugging was inefficient, and exporting was painful.

Key Takeaway: The only setups that consistently worked long-term were those where the developer fully owned the codebase. Tools that trapped everything inside their own environment hit limitations once the project moved beyond the MVP stage.
