Ghostty Introduces Automatic Scrollback Compression, Cutting RAM Use by Up to 90%

The Ghostty terminal emulator is adding automatic scrollback compression. The new feature reduces the memory needed for stored terminal output. Tests show RAM usage can drop by up to 90 percent compared with uncompressed scrollback. Compression operates transparently as users scroll through history. The enhancement aims to improve performance on low‑memory systems. Users will benefit from longer scrollback buffers without exhausting resources. The update is demonstrated in a recent video walkthrough. Future releases may refine the compression algorithm for even greater efficiency.
