WeWeb vs Bubble: Which No-Code Platform for AI Applications?

If you're building an AI-powered application without a traditional development team, you've probably narrowed your options down to WeWeb or Bubble. Both are powerful, but they serve different needs.

After building dozens of client applications on both platforms, here's my honest take.

The Short Answer

Choose WeWeb if: You need performance, flexibility, and plan to integrate with external databases (like Supabase) and AI APIs.

Choose Bubble if: You want an all-in-one solution with a gentler learning curve and don't mind vendor lock-in.

Performance: WeWeb Wins

This isn't even close. WeWeb generates static sites that load in milliseconds. Bubble apps can feel sluggish, especially as they grow.

For AI applications where users expect instant responses, performance matters. Nobody wants to wait 3 seconds for a page to load before they can even interact with your AI assistant.

Real numbers from my projects:

• WeWeb average page load: 0.8-1.2 seconds
• Bubble average page load: 2.5-4 seconds

Database Flexibility: WeWeb Wins

Bubble locks you into their proprietary database. It works, but:

• You can't easily migrate your data
• Complex queries get expensive fast
• Scaling costs can surprise you

WeWeb connects to any backend. I typically pair it with Supabase, which gives you:

• PostgreSQL (industry standard)
• Real-time subscriptions
• Row-level security
• Full data ownership

For AI apps that need to store conversations, embeddings, or user data, this flexibility is crucial.

AI Integration: Tie (with caveats)

Both platforms can integrate with OpenAI, Anthropic, and other AI providers. But the approach differs.

Bubble: Has plugins that abstract away API calls. Easier to start, but you're limited to what the plugin supports.

WeWeb: You'll write API calls directly or use n8n for complex workflows. More setup, but unlimited flexibility.

If you're building something beyond a simple chatbot—like RAG systems, AI agents, or custom workflows—WeWeb's flexibility becomes essential.

Learning Curve: Bubble Wins

Bubble is genuinely easier to learn. The visual programming model clicks faster for most people.

WeWeb requires understanding:

• How APIs work
• Basic data modeling
• Possibly some JavaScript for advanced features

If you're non-technical and need something working this week, Bubble might be the pragmatic choice.

Pricing at Scale: WeWeb Wins

Bubble's pricing scales with usage. As your app grows, so does your bill—sometimes dramatically.

WeWeb has simpler, more predictable pricing. And since you're using external services (Supabase, n8n), you can optimize each piece independently.

My Recommendation for AI Applications

For serious AI applications, I build on WeWeb + Supabase + n8n. Here's why:

• Performance - AI apps need to feel responsive
• Data ownership - Your training data and user data stays yours
• Flexibility - AI is evolving fast; you need a stack that can adapt
• Cost control - Scale without surprise bills

Bubble is fine for MVPs and simpler use cases. But if you're building something meant to last and scale, WeWeb is the better foundation.
