Sandcovery

One API for every sandbox provider

Create ephemeral sandboxes on E2B, Daytona, Vercel Sandbox, and Depot with one key. Sandcovery picks the provider, falls back when a create fails, and destroys every sandbox at its TTL.

Route every create

Sandcovery ranks your providers for each create and moves on when one fails.

Routing suffixes

A size name takes a suffix that picks how providers rank.

2x4:most-reliableBest uptime, last 15 minutes

Fallback

A failed create moves to the next provider, and the activity log lists every attempt.

One spec for every provider

Describe a sandbox once. An option a provider cannot enforce fails with unsupported instead of being ignored.

Guaranteed teardown

Sandcovery destroys each sandbox when its TTL ends, even if your client never comes back.
