Sentry CEO's Terra project cost $388.83 in Claude tokens, dashboard shows
zeeg · x · 2026-10-12
Sentry CEO David Cramer shared a cost dashboard for Terra, a project built by two people: $388.83 at list prices, with $384.36 from Claude and $4.47 in Tripo credits.
Key numbers:
- 3.4M output tokens, 11.9M input tokens, 3.1K messages
- zeeg personally spent $355.15 (3.1M output tokens); grichadev $33.68
- Costs are tallied from Claude Code session transcripts in the repo, each message counted once, with scripts tracking each Tripo task
He calls it "useless, but fun" — essentially a public dashboard for the hidden API cost of AI-assisted coding, and the auto-accounting-from-transcripts trick is the interesting part.
