Thirteen contenders

Thirteen cloud sandboxes, mapped on the two axes that actually divide them: how much state they keep and how much compute they carry. Every contender races the same circuit — there is no house favorite.

Every contender, head to head

Capabilities and per-second pricing from public vendor docs (June 2026). The objective composite is the same number the leaderboard uses. Where a vendor does not publish a rate we mark it with an asterisk.
