Every IDE that supports Nim does it as an afterthought. You install a language server plugin, bolt it onto VS Code or Sublime, and hope the latest update didn't break something.

No Electron. No bundled Chromium. No 300MB of RAM just to open a file.

Cold start: < 1 second

RAM usage (idle): ~35 MB
