Firebase Studio - Pros & Cons
Pros
- ✓Tight integration with Firebase Auth, Firestore, Cloud Functions, and Hosting
- ✓Hosted VM per project means no local setup — nothing to install
- ✓Gemini 3 Pro and Deep Think available directly in the assistant
- ✓Preview environments cover web plus Android/iOS emulators
- ✓MCP client lets external tools plug into the Gemini panel
Cons
- ✗Browser-only IDE — no offline mode and higher latency than a local editor
- ✗Deeply Google-centric; less appealing if your stack lives on AWS or Azure
- ✗Blaze billing surprises are easy — usage-based charges for backend and assistant compound
- ✗Gemini Code Assist pricing is a separate SKU on top of workspace costs
- ✗Assistant quality still trails Cursor and Claude Code on complex refactors
Bolt.new - Pros & Cons
Pros
- ✓Zero local setup — everything runs in the browser via WebContainer
- ✓Auto-routes between Claude, GPT, and Gemini for best-fit model per task
- ✓One-click Netlify deploy plus GitHub sync keeps output real, not throwaway

- ✓Mobile apps let you build and edit from an iPhone or Android
Cons
- ✗Credit-based pricing burns fast on large projects and error-heavy iterations
- ✗Only supports web/Node stacks — no native iOS, Android, or Python backends
- ✗No MCP server integration; extending with custom tools requires code
- ✗Generated code quality can drift on projects over a few thousand LOC
