Pay for what executes, not what exists.
edit.dev is a full development environment — compilers, services, databases — free in your browser, on your own compute. In the cloud it bills per process execution: idle is $0, nothing to size, running in milliseconds.
Agents changed the math: every agent, branch, and experiment wants its own machine. So give every one its own: each is a suspendable WebAssembly process — free to keep, milliseconds to wake.
a machine per agent, per subagent — have millions; pay only for the seconds they work
every environment is a link — send it; a teammate is up and running in seconds
CI that can't disagree with your laptop — same environment everywhere; only what changed ever runs
even compilers are WebAssembly — every build has a hash; your team never waits on the same compile twice
