4 ways to reduce Zed RAM usage
1 Keep extensions modest
Each extension adds ~4 MB. Even with 20, total cost is only ~75 MB — still 10x lighter than VS Code.
2 Use built-in LSP
Zed has built-in language server support. No need for separate language server extensions that multiply processes.
3 Close unused project tabs
Zed indexes open projects in the background. Close projects you're not actively editing.
4 Use the built-in terminal
Run your dev server inside Zed instead of a separate terminal app. One fewer process.
How DevPulse helps with Zed
DevPulse recommends Zed when VS Code or Cursor exceed 800 MB. If Zed is running, it confirms it's staying lean and warns if unusual memory growth occurs.
Instead of guessing how much RAM Zed consumes or manually checking Activity Monitor, DevPulse gives you a clear, always-visible answer in your menu bar.
