Lem is the editor/IDE well-tuned for Common Lisp.

After installing lem, you can start developing in Common Lisp at once.

You can skip over writing tidy settings or installing many plugins as you do on Emacs.

Lem supports other programming languages thanks to its built-in LSP client. You can choose between an Emacs and a Vim mode.

Other Lem features include:

• a project explorer tree view
• project-aware commands
• interactive grep and git interfaces
• multiple cursors
• tetris
• and more…
