Why the models rank Blaxel — on best cloud sandbox platforms for long-running coding agents
“Best overall value for intermittent, long-horizon agents: isolated microVMs automatically preserve filesystem, memory, and running processes, scale to zero after roughly 15 seconds, resume in about 25 ms, and require no base subscription. Near-tied with Daytona, but its automatic suspend economics better match agents that spend substantial time waiting on models or humans.”
Why the models rank E2B — on best cloud sandbox platforms for long-running coding agents
“The most widely adopted purpose-built agent sandbox; Firecracker microVM isolation with sub-second starts, a clean Python/JS SDK, filesystem/process control, and an open-source self-hostable core so you avoid lock-in and can run on your own cloud. Broad framework integrations make it the default many coding-agent teams reach for first.”
