Kedge meters the resources an app actually consumes per second. The public
preview includes a limited free trial; the rates on this page are estimates for
future paid service and may change.

## resource limits and billing

The `cpus`, `memory`, and `volume.size` settings are optional guardrails. They
set an upper limit on what an app may consume; they do not reserve capacity or
create a fixed-price instance. Billing measures runtime use beneath those
limits:

- **CPU:** time your code is scheduled on a core. Waiting for I/O accrues
  nothing.
- **Memory:** pages touched recently, not the configured limit. Resident memory
  is used when working-set measurement is unavailable.
- **Egress:** bytes leaving the app.
- **Storage:** bytes stored. Sparse databases and volumes bill written data,
  not their logical limit.

For example, an app limited to 4 vCPUs, 8 GiB of memory, and 100 GiB of storage
but averaging 0.25 vCPU, a 400 MiB working set, and 2 GiB stored is billed for
the latter amounts.

A scaled-to-zero app has no running CPU or memory usage, so it accrues only its
stored-data cost. A machine paused by [`idle-suspend`](/docs/volumes) is the
same: it accrues only stored data while paused.

## rates

| resource | rate |
|----------|------|
| CPU | $15 / vCPU-month ($0.0205 / vCPU-hour) |
| Memory | $5 / GiB-month ($0.0068 / GiB-hour) |
| Storage | $0.05 / GiB-month |
| Egress | $0.01 / GiB |

A vCPU-month is 730 vCPU-hours. Billing is per second; the monthly figure is a
reference scale.

## the free tier

Every account includes $5 of monthly usage, consumed before
paid credit.

## coding-agent model usage

Coding-agent sessions using Kedge's model include a separate
$2 monthly allowance. Input, cached input, and output tokens
are charged at the selected model's rate and itemized in the billing ledger.
Exhausting this allowance stops new model work without consuming the resource
credit that keeps apps running.

## credits and enforcement

Usage draws down your credit balance. The [billing page](/billing) shows the
balance, trailing-hour and trailing-day run rate, 30-day burn-down, and
transaction ledger.

Kedge notifies you below $1 and suspends the account at zero; apps stop and
data remains. During beta, email
[support@kedge.dev](mailto:support@kedge.dev) for more credit.
