I built the same app with 4 AI's. Who built it best? Here are the results. The test: Build a client management dashboard for a digital agency. Using the exact same prompt for each. Ranking based on: > UI/Design > Logic & Functionality > Backend/Database > Ease of Use Let's break it down: Tool 1: Bolt ⏱️ Time: 10-15 min (slower) 🎨 Design: 6.5/10 - Basic, but functional ⚙️ Logic: 7/10 - Everything worked 🗄️ Backend: 8/10 - Seamless Supabase integration, built-in security scanner 🧭 Ease of use: 7.5/10 Solid all-around. Nothing flashy, nothing broken. Tool 2: Base44 ⏱️ Time: Few minutes 🎨 Design: 6.5/10 - Very "vibe coded" looking ⚙️ Logic: 7/10 - Did the job 🗄️ Backend: 8/10 - Auto-built Google auth which was nice 🧭 Ease of use: 6.5/10 - UI feels clunky The underdog. Works, but feels like it's playing catch-up on polish. Tool 3: Replit ⏱️ Time: 20-30 min 🎨 Design: 7.5/10 - Actually tried to match the reference ⚙️ Logic: 7/10 - Standard 🗄️ Backend: 6/10 - Confusing, hard to navigate 🧭 Ease of use: 3/10 One prompt and I hit usage limits. Couldn't even continue building. Brutal experience. Tool 4: Lovable ⏱️ Time: ~5 min (fastest) 🎨 Design: 7/10 - Cleanest, most polished ⚙️ Logic: 7.5/10 - Smart intuition (reminded me to create clients before projects) 🗄️Backend: 8/10 - Seamless with options 🧭 Ease of use: 9/10 Just works. Everything feels intuitive. Final rankings: 🥇 Lovable - Best overall experience 🥈 Bolt - Reliable second 🥉 Base44 - Needs polish 4️⃣ Replit - Stuck in no-man's land The truth? They're all using the same AI models. The difference is UX. Key takeaway: These tools live or die by ease of use. Replit is caught between "dev tool" and "no-code" - serving neither well. For non-technical builders: Lovable or Bolt. For technical folks: Just use Cursor. Full video breakdown on my channel. Comment "Ranking" for the link, or search on YT.
