Aider
- +Fully open source (Apache-2.0) and free; you only pay your chosen model provider
- +Git-native: every AI change is a reviewable, revertible commit
- +Model-agnostic with a repo map that scales to larger codebases
- -Terminal-only with no GUI or IDE-native experience for those who want one
- -Runs locally and edits real files, so a human must review every change
Firebase Studio
- +Free during the preview period, with no seat fees or credit card required to start (3 workspaces, more for Google Developer Program members)
- +Two real entry points: prompt-to-app prototyping and a full Code OSS IDE, both with Gemini assistance
- +Tight Firebase and Google Cloud integration, broad framework support, MCP and Gemini CLI extensibility
- -Announced sunset on March 22, 2027, with migration pushed to Google AI Studio or Google Antigravity, a real continuity risk
- -Still in preview with no SLA or deprecation policy and evolving features
