fleet
One API for every agent pod. A pod is a Linux machine your agent can run commands in.
Fleet starts each pod on the cheapest sandbox provider you have a key for, and moves to the next one when a provider fails. You bring your own provider accounts: connect each one once in the cabinet (fleet keeps the key encrypted), or send its key with each call.
Status: beta, live at https://fleet.flisk.si. Sign in with GitHub to reach the cabinet: up to 10 named fleet keys, your pods, an overview, providers and docs. Daytona, Blaxel, Upstash Box, Vercel Sandbox, E2B, Freestyle and Tensorlake have been run end to end on a real account. The other ten adapters are written from the providers' public API docs and tested against fake replies only.

Most providers need one API key. Three need more, joined with colons in one header value (the cabinet's Providers page has one input per part): Blaxel workspace:key, Vercel token:projectId[:teamId], boat key[:organization].
Working means fleet has started, run commands and files in, and stopped pods on a real account of that provider. Untested providers are built from public docs and pass tests against fake replies, so they should work; they wait for a test on a real account (bun scripts/real-check.mjs). Blocked providers cannot be tested yet: the provider is down, asks for a card, or is invitation only. Have an account at one of them, or want another provider (#4)? Help is welcome.
Prices were read on 2026-11-12. You pay each provider directly on your own account; fleet adds nothing.
Not added, because fleet is a Worker that only speaks plain HTTP: Modal (no public HTTP API, its SDKs use gRPC), Northflank (commands only over an HTTP/2 or WebSocket stream), CodeSandbox (its HTTP exec is undocumented) and Cloudflare Sandbox (each user would deploy their own Worker).
API
Send your fleet key as Authorization: Bearer fleet_..., plus one header per provider you hold an account at.
curl -X POST https://fleet.flisk.si/v1/pods \
-H "Authorization: Bearer fleet_..." \
-H "X-E2B-Key: ..." -H "X-Daytona-Key: ..." \
-d '{"cpu":2,"ram":4}'
