Show HN: Subtle – Local, open-source analytics for Claude Code sessions
I’m used to having good observability for systems and workflows, but now that I generally start development with Claude Code vs my IDE, I lost a layer of visibility into how my code is produced.
Subtle (https://github.com/itsderek23/subtle) is a free, open-source app for analyzing Claude Code logs that runs entirely on your local machine. It lets you:
* See overall Claude Code usage over time (broken down by AI vs tool time) * Count Claude-assisted Git commits over time * Visualize individual sessions with a trace showing how time is spent * Filter sessions by message text * View session transcripts
I don’t yet know what “good” Claude Code usage looks like ... fewer interventions? Smaller commits and PRs? Lower code churn within a session? Would love your thoughts.
