## Who it is for

- **Best for**: Developers who live in the terminal, prioritize granular git history, or require AI coding assistance in IDE-less or remote SSH/Docker environments.
- **Not ideal for**: Users who prefer GUI-based workflows, rely heavily on tab-autocomplete, or require official support for modern Python interpreters (3.13+) and active upstream maintenance.

## Verdict

Aider is a highly efficient, terminal-native tool that excels at maintaining clean git history and handling large codebases, but its current lack of maintenance and compatibility with newer Python versions makes it best suited for power users willing to manage their own configurations.

## Recent updates

As of late 2026, active development on the main branch has stalled with the last commit in May 2026. The latest stable release remains v0.86.2, and many users have migrated to community-maintained forks like cecli for updated model support.
