LLM provider endpoints this gateway exposes to sandboxes. The gateway proxies requests and injects credentials automatically — agents call a stable local URL and never see raw API keys.

Some changes require recreating the gateway to take effect.
Supervisor
Supervisor image
The supervisor process runs inside every sandbox on this gateway and enforces security policies. It connects back to the gateway via an outbound gRPC stream — no inbound port is opened in the sandbox.

Security enforcement
These policies are applied by the supervisor to all sandboxes on this gateway. Disabling any layer reduces isolation — only do so temporarily for debugging.
Filesystem isolation Landlock
Restricts sandbox filesystem access to declared paths only. Strict mode denies all unlisted paths; permissive mode logs violations instead.
Process isolation seccomp
Filters syscalls available to sandbox processes using the default seccomp profile. Reduces the kernel attack surface.
Network policy proxy OPA
Intercepts outbound HTTP/HTTPS traffic from sandbox processes. In enforce mode, requests that do not match an attached provider's allow-list are blocked and credentials are injected for matching hosts. In audit mode, violations are logged but not blocked.
Session & Defaults
SSH session TTL
Inactive SSH sessions are closed after this many seconds. Active sessions are unaffected. Applies to all sandboxes on this gateway.
s
Service forwarding
Allows sandboxes to expose services running on loopback to the host browser via the supervisor relay. Required for previewing web UIs, Jupyter notebooks, or any local service an agent starts inside the sandbox.
Log level
Verbosity of gateway and supervisor logs. Use debug only when diagnosing issues — it produces significant output.
Max concurrent sandboxes
Hard limit on simultaneously running sandboxes across all agents on this gateway. Set to 0 for unlimited.
Default CPU limit
CPU cores allocated per sandbox when the session request does not specify a limit. Applies across all drivers.
cores
Default memory limit
Memory in MiB allocated per sandbox when the session request does not specify a limit.
MiB
Auth & Token Issuance
The gateway issues short-lived JWTs for session auth, signed with an Ed25519 key pair managed by Kaiden.
