4 ways to reduce Ghostty RAM usage
1 Update to v1.3+
A critical memory leak was fixed in early 2026. Make sure you're on the latest version.
2 Use native splits
Ghostty's built-in split panes eliminate the need for tmux, saving that process overhead.
3 Set scrollback limit
Configure scrollback-limit to 10,000 lines rather than unlimited to keep memory bounded.
4 Nerd Fonts work out of the box
Ghostty supports ligatures and Nerd Fonts natively — no special configuration needed.
How DevPulse helps with Ghostty
DevPulse recommends Ghostty as a lightweight replacement for iTerm2 (saves ~80 MB) and Warp (saves ~210 MB). It monitors for memory growth patterns.
Instead of guessing how much RAM Ghostty consumes or manually checking Activity Monitor, DevPulse gives you a clear, always-visible answer in your menu bar.
