Overview
OpenSandbox provides isolated environments where agents execute code, run shell commands, manage files and drive browsers or desktops, through a single lifecycle API. It runs locally on Docker and scales to Kubernetes, with SDKs for Python, Java/Kotlin, TypeScript, C#/.NET and Go, plus an `osb` CLI and an MCP server. Egress policies, an ingress gateway and a credential vault control network access.
Who it is for: Engineers needing isolated code execution for agents on their own infrastructure
Strengths
- SDKs in five languages plus osb CLI and MCP server
- Same lifecycle API for local Docker and Kubernetes deployments
- Per-sandbox egress policies and a credential vault keep real secrets out of workloads
- Firecracker runtime with pause/resume; reported 64 ms P50 creation time
Weaknesses
- Docker required for local use; Kubernetes setup needed for the fast runtime
- No hosted demo or playground listed in the README
- Firecracker and pause/resume features documented only for the Kubernetes fast runtime
- Server needs separate install and TOML configuration before first use
What it needs
- no GPU
- Needs Docker, Python 3.10+, Kubernetes (optional, for cluster deployment)
