AI Agent Infrastructure

Give your agents
their own room.

Warden provides isolated, secure execution environments for AI coding agents. They run code, browse the web, and build software — without ever touching your production systems.

how it works

One API. Infinite isolation.

01

Create a sandbox

Call the Warden API with your runtime requirements. We provision a fresh, isolated microVM in under 200ms — ready for your agent to work in.

02

Agent works inside

Your agent reads files, runs shell commands, installs packages, executes code — all sandboxed. Zero access to your host machine, secrets, or production environment.

03

Stream results back

Structured logs, stdout/stderr, file diffs, and process trees stream in real time. When the session ends, the sandbox is destroyed — artifacts and all.

capabilities

Built for agent-native code execution

Streaming code execution

Run Python, Node.js, Bash, or any containerized runtime. Stream output as it happens — not when the session finishes.

Complete isolation

Firecracker microVMs with dedicated kernel and network stack. Guest kernel exploits can't reach your infrastructure.

Process tree visibility

Real-time view of every process, network connection, and filesystem write your agent makes. Full observability by default.

Snapshot and resume

Snapshot a sandbox state before a risky operation. Resume from that point if something goes wrong — or branch off to try again.

MCP-first integration

Native Model Context Protocol server. Agents that speak MCP connect to Warden without SDK boilerplate — just point and run.

Configurable egress

Allow outbound HTTP to specific domains only. Block everything else by default. Credential injection without exposing secrets.

The blast radius is zero.

When you give an agent unrestricted access to your machine, a prompt injection, a hallucinated rm -rf, or a compromised dependency becomes your problem. Warden contains it.

No host kernel access — every sandbox gets its own
Network namespace isolated — no lateral movement
Filesystem writes contained to ephemeral layer
Secrets injected at runtime, never in the sandbox image
Sessions auto-destroy — no persistent state to leak

Your agent is only as safe as its environment.

Warden makes sandbox execution trivial — so the default for every agent becomes "run it in a box," not "hope nothing breaks."
