Score: 6.0/10 (Innovation: 5, Technical: 6, Documentation: 7, Utility: 6)

Summer is a local, open-source CLI tool that tracks AI coding usage and spend across multiple coding assistants (Claude Code, Codex, OpenCode) per developer. It offers a local dashboard and relies on Autumn as its backend for aggregation, making team-wide cost visibility straightforward and self-hosted. Its main appeal is solving the practical problem of understanding AI usage costs across a team.

Target audience: backend devs, devops, engineering managers, data engineers
