Claude Code · Codex · OpenCode

Your AI coding usage, beautifully measured.

agentmon reads your local Claude Code, Codex & OpenCode transcripts and turns them into tokens, cost, models, sessions and rhythm — all on your machine. Nothing is uploaded.

…or drag & drop your .claude / .codex folder here

Can't find your folder?⌄

.claude and .codex are hidden folders, so the file dialog won't show them by default. Easiest fixes:

1. Jump straight to it. In the dialog press the dialog’s path field, paste a path below, and open it — this reveals the hidden folder in one step. Picking .claude directly works.

2. Or reveal hidden files (enable “show hidden files” in the dialog), then open the folder directly.

3. Or pick your home folder — nothing else on your disk is read; we only step into .claude / .codex.

Each pick connects one folder — connected one tool but not the other? Use “add folder” in the header to merge more in.
