[03] SecurityBy default
Secured for AI workloads
Firecracker isolation
Every agent and tool call runs in its own microVM. No shared kernels or cross-tenant state — stronger isolation than containers or local worktrees.
Credentials broker
Agents should not possess credentials. Our broker sits between your agent and the APIs it calls, eliminating exfiltration risk with brokered access.
Network controls
Control egress traffic to specified URLs and IPs. Every outbound connection is logged, every rule is yours.
SOC 2 Type 2 · HIPAA · GDPR
Security documentation and compliance reports available in the trust center.
[05] Programmatic controlSDK · API
Best in class agent experience
Streaming
Execute code and commands in isolated environments with real-time output streaming.
Durable filesystem
Read, write, and manage files across sessions. State persists exactly as the agent left it.
Elastic resource allocation
Let your agents request CPU/memory resources on the fly from within the box.
Preview URLs
Expose ports from inside a sandbox to a public URL for instant previews.
MCP
Connect to your sandboxes via the Model Context Protocol from any MCP-compatible agent.
Docker support
Run Docker containers natively inside the sandbox, with no compromises on the tooling your agents depend on.
