Approximate open-source repo examples
Approximate ranges assume standard ignore patterns and the current tiered chunking strategy. Initial indexing is one-time; maintenance usually tracks changed files only.
| Repository | Approximate size | Initial index tokens | Typical monthly tokens |
|---|---|---|---|
| expressjs/express | 25k-40k LoC | ~0.2M-0.6M | ~10k-60k / month |
| fastapi/fastapi | 60k-100k LoC | ~0.6M-1.5M | ~30k-150k / month |
| vercel/next.js | 300k-500k LoC | ~3M-7M | ~150k-700k / month |
Maintenance assumes regular incremental development. Large refactors, dependency lockfile churn, or force re-index operations will increase usage.
