Sandbox file transfer, snapshots, and live setup status

Overview

This release adds amika scp for moving files into and out of a sandbox over SSH, and brings sandbox snapshots to full parity across the CLI and TypeScript SDK so you can capture a sandbox and reuse it as a starting point elsewhere. Sandbox status is now more accurate and visible, with live setup progress as a sandbox comes online, and sandboxes are more resilient to setup and shutdown hiccups. You can also open a sandbox directly in CMUX.

What's new

File transfer

• amika scp: Copy files to and from a sandbox over SSH with a single command. It supports the SSH options you'd expect — host keys, jump hosts, IPv6 addresses, custom ports, and more — so it drops into existing SSH-based workflows.

Snapshots

• Snapshot management: Create, list, and delete sandbox snapshots with amika snapshot create, list, and delete, and start a new sandbox from a saved snapshot with sandbox create --snapshot.
• TypeScript SDK support: Snapshots are now available in the TypeScript SDK too, so you can capture and restore sandbox state from your own code, not just the CLI.

Visibility

• Live setup progress: The sandbox list and detail pages now show real-time progress while a sandbox is being prepared, and refresh automatically until it's ready.
• Open in CMUX: Launch a sandbox directly in CMUX from the sandbox page (Daytona sandboxes only).

Reliability

• Sandbox status is now more accurate and consistent across providers, with a clear distinction between a sandbox that's spinning up and one that's finished setting up.
• Sandboxes stay usable even if VM initialization fails partway through.
• Stopping a sandbox is more reliable, including for sandboxes that are still starting up or already suspended.
• General improvements to sandbox startup reliability.
