# Compatibility (/docs/reference/compatibility)



The matrix is generated from the same capability declarations exported by the adapters. A dash means the normalized operation is unsupported; provider-native behavior may still exist on `sandbox.raw`.

## Important differences [#important-differences]

* Local uses AgentOS as its in-process isolation boundary, with private bridged ports, deny-by-default
  networking and beta runtime status.
* E2B and Daytona can issue authenticated preview URLs through `preview.request()`.
* Vercel and E2B snapshots create provider-native artifacts, but restore creates a new native sandbox and stays on `raw`.
* Daytona persistence, PTYs, networking, images, and GPUs are provider-native capabilities beyond the normalized core.
* Upstash Box provides durable filesystems, pause and resume, network policies, and public or bearer-token URLs; snapshot restore creates a new native Box.
