Devbox sandbox infrastructure purpose-built for running and evaluating AI coding agents.
Provides isolated micro-VM devboxes with VM-plus-container security layers, snapshots for saving and branching agent state, and reusable blueprint templates. Includes built-in public benchmarks such as SWE-Bench and R2E-Gym, custom benchmark and scenario evaluation, and fine-tuning support alongside a REST API, Python and TypeScript SDKs, and a CLI. The vendor cites sub-2-second startup for 10GB images and customers running 10,000 concurrent devboxes; compute, memory, and storage are billed by usage.
Strengths
- Coding-agent focus with built-in SWE-Bench-style benchmarks and scenario evals
- Snapshot and branching model for saving and forking agent state
- Vendor-reported fast startup and proven scale to 10,000 concurrent devboxes
- MIT-licensed Python and TypeScript SDKs plus CLI
Tradeoffs
- Closed-source platform with no self-hosting outside enterprise VPC deployment
- Production features such as suspend/resume and custom benchmarks require the $250/month Pro tier
- Smaller open-source ecosystem than general-purpose sandbox alternatives
