Documented steps

  1. Persist the sandbox ID when you create it (e.g. keyed by your user/session), or set metadata at creation and find it later via Sandbox.list() filtering (https://e2b.dev/docs/sandbox/metadata)
  2. From any process, reconnect with JS `await Sandbox.connect(sandboxId)` / Python `Sandbox.connect(sandbox_id)` (https://e2b.dev/docs/sandbox/connect); CLI: `e2b sandbox connect <sandbox-id>`
  3. connect() works for both running sandboxes (attaches) and paused ones (resumes them)
  4. The sandbox keeps running after your process disconnects — lifetime is governed by its timeout/lifecycle config, not by your connection
