tl;dr: Libghostty-vt 1.0, a portable C library for terminal emulation extracted from Ghostty, has been released with a stable ABI and semantic versioning. It's already powering JetBrains IDEs (12.5M+ users), has an approved PR to replace libvterm in Neovim, and is used by OrbStack, Vercel's Turborepo, and others, with bindings across most major languages. The MIT-licensed library supports Linux, macOS, iOS, FreeBSD, Windows, Android, and WebAssembly, has no copyleft dependencies, creates no threads, and can run freestanding without libc.
