Fragments vs Lovable

Fragments

Best treated as a starter kit rather than a finished product: it shows how to build a chat-to-app builder with sandboxed execution, and gives you a working base to fork. Skip it if you just want a polished hosted app builder.

Pros

• +Apache-2.0 license with an active public repository
• +Runs generated Python, Next.js, Vue, Streamlit and Gradio apps in isolation
• +Works with many model providers, including local Ollama
• +Easy to add your own stacks and models

Cons

• −Requires an E2B account and an LLM key to run anywhere
• −Hosted demo is a showcase, not a supported service
• −No dedicated pricing or support of its own

Lovable

The cleanest prompt-to-app experience for someone who cannot write React, and GitHub sync means you are not locked in — but 100 credits a month is less runway than it sounds once the app gets real.

Pros

• +Live preview after each change keeps iteration legible to non-developers
• +GitHub sync and Supabase mean the output is real, portable code
• +The free tier is enough to find out whether the idea works
• +Per-action credit costs are published, so estimating is possible

Cons

• −Free tier caps at 30 credits a month regardless of the daily grant
• −Debugging a bad generation can cost more credits than the original build
• −Opinionated stack — React front end, Supabase back end, little room to differ
• −No API for driving builds programmatically
