+E2B uses [usage-based pricing](#usage-based-pricing) - you pay only for what you use. New users receive $100 in free credits to get started.

+
+## Plans
+
+| Feature | Hobby | Pro | Enterprise |
+|---------|-------|-----|------------|
+| **Base price** | $0/month | $150/month | Custom |
+| **Free credits** | $100 (one-time) | $100 (one-time) | Custom |
+| **Max session length** | 1 hour | 24 hours | Custom |
+| **Concurrent sandboxes** | 20 | 100 - 1,100 | 1,100+ |
+
+<Note>
+Pro plan includes 100 concurrent sandboxes. Higher concurrency up to 1,100 is available as a purchasable add-on.
+</Note>
+
+Plans have different [API rate limits](/docs/sandbox/rate-limits).
+
+To upgrade your plan or purchase add-ons, visit the [dashboard billing tab](https://e2b.dev/dashboard?tab=billing). For Enterprise plans, [contact sales](mailto:enterprise@e2b.dev).

+
+## Usage-based pricing
+
+You pay per second for the **allocated compute resources** defined in your template, not actual CPU/RAM usage. Charges accrue for the entire time a sandbox is running.
+
+<Note>
+**Important**: You are billed based on the CPU and RAM **allocated** to your sandbox template, regardless of how much your code actually uses. Make sure to kill or pause sandboxes when not in use to avoid unnecessary charges.
+</Note>
+
+### Compute costs
+
+Use the [usage cost calculator](https://e2b.dev/pricing#:~:text=Usage%20Cost%20Calculator) on our pricing page to estimate costs for your specific configuration.
+
+### Customizing compute resources
+
+You can customize allocated CPU and RAM when building custom templates by specifying `cpuCount` and `memoryMB` in the build configuration.
+
+<CodeGroup>
+```js JavaScript & TypeScript
+import { Template, defaultBuildLogger } from 'e2b'
+
+// This template will be billed for 8 vCPU + 4 GB RAM
+// whenever a sandbox from it is running
+await Template.build(template, {
+  alias: "my-template",
+  cpuCount: 8,
+  memoryMB: 4096,
+  onBuildLogs: defaultBuildLogger(),
+})
+```
+```python Python
+from e2b import Template, default_build_logger
+
+# This template will be billed for 8 vCPU + 4 GB RAM
+# whenever a sandbox from it is running
+Template.build(
+    template,
+    alias="my-template",
+    cpu_count=8,
+    memory_mb=4096,
+    on_build_logs=default_build_logger(),
+)
+```
+</CodeGroup>
+
+See [template quickstart](/docs/template/quickstart) for more details on building custom templates.
+
+<Note>
+Higher allocated resources mean higher costs. For example, a sandbox with 8 vCPU and 4 GB RAM costs $0.468 per hour while running.
+</Note>

+## FAQ
+
+<AccordionGroup>
+  <Accordion title="When am I charged?">
+    Usage costs accumulate throughout the month as you run sandboxes. Your payment card is charged at the end of each monthly billing cycle for the total accumulated usage.
+  </Accordion>
+
+  <Accordion title="Am I charged for actual CPU/RAM usage or allocated resources?">
+    You're charged for the **allocated** resources defined in your template, not the actual CPU/RAM your code uses. A sandbox with 8 vCPU allocated costs the same whether it uses 10% or 100% of that CPU.
+  </Accordion>
+
+  <Accordion title="What happens when I run out of credits?">
+    Once credits are exhausted, you'll need to add a payment method to continue using E2B. Existing sandboxes will continue running but you won't be able to create new ones.
+  </Accordion>
+
+  <Accordion title="Can I set spending limits?">
+    Yes, you can set spending limits on the [budget page](https://e2b.dev/dashboard?tab=budget) in your dashboard.
+  </Accordion>
+
+  <Accordion title="How do I optimize costs?">
+    - **Always kill sandboxes when done** - Use `sbx.kill()` to stop billing immediately
+    - **Allocate only what you need** - Start with default resources (2 vCPU, 1 GB RAM) and increase only if necessary
+    - **Implement automatic timeouts** - Set max session lengths to prevent forgotten sandboxes from running
+    - **Monitor actively running sandboxes** - Use the [CLI](/docs/cli/list-sandboxes) or [dashboard](https://e2b.dev/dashboard?tab=usage) to track active sandboxes
+    - **Use lifecycle events** - Set up [webhooks](/docs/sandbox/lifecycle-events-webhooks) to get notified when sandboxes are created
+  </Accordion>
+
+  <Accordion title="Do I pay for stopped sandboxes?">
+    No. You only pay while a sandbox is actively running. Once a sandbox is killed or times out, billing stops immediately.
+  </Accordion>
