Sandbox lifecycle and OS tradeoffs

The real buying decision here is not whether state exists, it is how long that state lives, what part of the machine survives, and on which operating systems. E2B gives each session a Linux microVM with pause and resume and filesystem persistence, while Daytona offers a broader lifecycle menu across container, VM, Windows, macOS, and GPU sandboxes, with configurable stop, pause, archive, and delete behavior tied to idle time and wall clock limits.1 2 3 4 5 6

• E2B is persistent in practice. Its product pages describe a filesystem that persists, pause and resume in the lifecycle, Pro sessions up to 24 hours, and enterprise support for multi day and persistent sessions. That means work can survive across agent turns, but within tighter session rules than Daytona exposes by default.2 3 4
• Daytona makes lifecycle policy a first class control surface. Persistent sandboxes can stop and start, pause and resume, archive files, or auto delete. Different sandbox types preserve different layers, containers keep filesystem state when stopped, VM sandboxes can also preserve memory when paused, and retention can be tuned per workload.5 6 7 8
• The operating system split matters because it changes what the agent can run. E2B centers on Linux microVMs. Daytona supports Linux, Windows, macOS, and GPU sandboxes, so teams choosing between them are often deciding whether they need a broader machine catalog or a narrower Linux environment with microVM isolation.2 5 9 10

This category is moving toward finer grained lifecycle controls rather than a simple persistent versus ephemeral divide. As agents run longer jobs, recover from interruptions, and use more than Linux, providers that let developers choose exactly when to pause, stop, archive, or delete each sandbox type will have the clearest edge.1 2 4 5 6 8
