The honest brief
Firebase Studio
Free and fully browser-based with no local setup, tying a real Code OSS editor straight into Gemini agents and the Firebase deploy stack.
- Runs fully in the browser, no setup
- Gemini agents and Genkit built in
- One-click deploy to Firebase
- Free core tier
- Prototype apps from a prompt
- Still in preview
- Tied to the Google/Firebase ecosystem
- Gemini-only assistant
- Workspace limits on the free tier
Kiro
Spec-first: writes requirements/design/tasks .md artifacts to disk before coding, unlike prompt-to-diff editors.
- Durable spec artifacts before implementation
- Built on Code OSS — VS Code extensions transfer
- Agent hooks automate actions on file events
- Runs on Claude Sonnet models
- Young product; agent still maturing
- Spec workflow adds overhead for small tasks
- Free tier capped at limited monthly interactions
