Safe execution for any game code.
Sandbox gives you isolated, reproducible containers for running untrusted player code, mod scripts, and game logic — with strict resource limits and full audit trails.
Fully isolated containers
Each sandbox runs in a gVisor-hardened container with no network access, no filesystem escape, and no inter-process visibility.
Mod and plugin execution
Let players run Lua, JavaScript, or Python mods safely. Sandbox enforces API surface limits so mods can only access what you explicitly allow.
Resource quotas
Set CPU, memory, and execution time caps per sandbox. Runaway scripts are terminated automatically, protecting your main server process.
Reproducible snapshots
Snapshot any sandbox state and replay it deterministically. Ideal for debugging desync issues or replaying competitive matches.
Sub-10ms cold start
Sandbox instances are pre-forked and ready before your code needs them. There is no noticeable delay between a player triggering an event and their script executing.
Version-pinned runtimes
Pin sandboxes to a specific runtime version per player or mod. Upgrades never break existing scripts without opt-in.
Full execution audit logs
Every syscall, API call, and output is captured and queryable. Use logs to investigate exploits, debug player issues, or meet compliance requirements.
Testing harness
Run automated tests against your game logic inside the same sandbox that production uses. What passes locally will pass in prod.
