I rebuilt my AI coding agent workspace in Rust. It uses 1/15 the memory of the Electron app I replaced

说明与用途

Krill 是基于 Rust 的编码代理工作区，使用的内存仅为 Electron 应用 Orca 的 1/15，CPU 仅为 1/27，且会话持久化且资源占用低。

问题

Running multiple coding agents in an Electron app caused excessive memory and CPU usage on a Mac.

结果

Krill uses 1/15 the memory and 1/27 the idle CPU of Orca for 10 terminals, with comparable install size and session persistence.

工作流

• Create a new session with krill new
• Open a repository and spawn worktrees
• Start agents via CLI (Claude Code, Codex, etc.)
• Monitor agent status hooks to queue approvals
• Reconnect to sessions after app restart using krill attach

证据

Krill uses 1/15 the memory of Orca's memory at 10 terminals

来源

At 10 terminals: Memory (phys_footprint) 85.9 MiB for Krill, 1,274.9 MiB for Orca

Krill took 7.5 s to finish the burst versus Orca's 4.0 s at 20 terminals

The agent workspace I was using did the job, but it was an Electron app, and with a dozen terminals open it had quietly become the heaviest thing on my Mac.
