E2B
Depot default code sandbox for agents. Use for untrusted code; Daytona when you need persistent devworkspaces. Also the depot default Linux desktop sandbox for computer-use (e2b-desktop + VNC stream) when you already standardize on E2B. Strengths: Purpose-built for LLM code execution; Strong isolation (microVMs); Excel
Strengths
- Purpose-built for LLM code execution
- Strong isolation (microVMs)
- Excellent agent SDK fit
Weaknesses
- Per-sandbox-second costs add up
- Less persistent than Daytona workspaces
- Younger than hyperscalers
Modal
Depot darling for Python agent backends and bursty GPU jobs. If you think in functions not VMs, start here. Strengths: Best-in-class Python DX for serverless compute; GPUs + sandboxes + cron in one model; Scale-to-zero economics.
Strengths
- Best-in-class Python DX for serverless compute
- GPUs + sandboxes + cron in one model
- Scale-to-zero economics
Weaknesses
- Premium vs raw RunPod $/GPU-sec sometimes
- Python-centric (polyglot harder)
- Less classic VM control
