Pricing
Lightarch uses a credit model — your monthly plan gives you a dollar credit that depletes as you ingest data. After the credit is exhausted, you're billed per GB at overage rates.
Plans
| Plan | Monthly credit | Traces + Logs | Overage rate | Metrics |
|---|---|---|---|---|
| Free | Hard cap | 500 MB total | — | — |
| Pro | $49/mo | ~15 GB | $0.30/GB | $0.10/M samples |
| Enterprise | $499/mo | ~192 GB | $0.20/GB | $0.10/M samples |
Traces/logs are billed at the higher of a per-GB rate or a small per-row minimum (small, frequent spans still cost a database row each). At typical span sizes, the per-row minimum is what actually governs spend, so "~15 GB" and "~192 GB" reflect real usage patterns rather than a simple credit ÷ $/GB division. Metrics are charged separately at $0.10 per million samples.
How credits work
Every byte ingested deducts from your monthly credit at the plan rate. The Usage page shows your credit balance, spend to date, and projected month-end spend. At 80% and 95% credit usage, you'll receive warning emails.
Free tier limits
The Free plan has a hard 500 MB cap with no overage — ingest stops returning 202 and returns 429 when the cap is reached. The cap resets monthly.
Billing cycle
Billing is monthly via Lemon Squeezy. Your credit renews on your subscription renewal date. View your billing portal from Settings → Manage billing.
