They’re all great ways to run AI-generated code. GX Sandbox matches the market on usage price, then adds a stronger isolation model, fine-grained egress, built-in audit, and the option to self-host.
| Capability | GX Sandbox | E2B | Daytona | Modal |
|---|---|---|---|---|
| Isolation (default) | Firecracker microVM per sandbox | Firecracker microVM | Container (shared kernel) | gVisor |
| Self-host / BYOC | Full self-host + BYOC | Open source, but heavy to self-host | Open source self-host | Managed only |
| Egress policy granularity | IP/CIDR + port + protocol + direction + domain | Domain + IP (L7 HTTP/TLS) | IPv4 CIDR | Block + CIDR + domain (beta) |
| Audit log | Built-in audit + timeline | Not documented | Yes | Yes |
| Snapshot / fast wake | Snapshot-based wake for services | Pause / resume | Image templates | Filesystem snapshot |
| SDKs | Python, TypeScript, CLI, REST | Python, JS, CLI | Python, TS, Ruby, Go, Java | Python-first |
| Usage price (list) | $0.0504 / vCPU-hr · $0.0162 / GB-hr | $0.0504 / vCPU-hr · $0.0162 / GB-hr | $0.0504 / vCPU-hr · $0.0162 / GB-hr | ~$0.0710 / vCPU-hr (Sandbox) |

A Firecracker microVM per sandbox is a real hardware-virtualized boundary — stronger than a shared-kernel container.
Self-host the whole platform or run the data plane in your own subscription (BYOC). Code and data stay inside your boundary.
Define egress policy per project by IP/CIDR, port, protocol, direction, and domain, with default-deny and logging.
A built-in audit log and per-sandbox timeline show who ran what and when — for incident response and compliance.
Projects, scoped API keys, per-project quotas, SSO and RBAC make a shared, multi-tenant cluster safe to hand to many teams.
Per-second usage at the same headline rate as E2B and Daytona, with seats and committed-use discounts for teams.
If you need first-class SDKs in Ruby, Go, or Java, Daytona covers more languages today. We’d rather tell you that up front than oversell — GX Sandbox is built for teams that need strong isolation, egress control, audit, and self-host for agent and code-execution workloads.
Same usage price. More control over your data.
