What is CRTty?

CRTty is a Rust-based post-processing shader framework that injects GLSL fragment shaders into kitty terminals (or any EGL/GLX OpenGL 3.3+ app) via LD_PRELOAD, no patching needed. It delivers built-in effects like CRT monitor simulation with scanlines, phosphor glow, barrel distortion, vignette, and chromatic aberration, plus greyscale and invert. Load custom .glsl files for live hot-reload effects, with auto uniforms for time and resolution—perfect for retro vibes on Linux terminals.

Why is it gaining traction?

Unlike game-focused post processing shaders for Citra, PPSSPP, Godot, Minecraft, or Unity URP post processing stacks on GitHub, CRTty brings similar OpenGL post-processing shader power to everyday terminals without drivers or recompiles. Hot-reload on save (triggers on redraws) and error overlays make shader experimentation frictionless, echoing Unity post processing shader graph workflows but for CLI warriors. The CLI launcher (`crtty -s my_shader.glsl`) simplifies launching kitty with effects, passing args seamlessly.

Who should use this?

Kitty terminal power users on Linux wanting authentic CRT glow for late-night coding sessions. Shader hobbyists tweaking GLSL for terminals, akin to post processing shader azahar or ffuf post processing GitHub hacks. Retro computing fans applying post processing shaders OpenGL-style to any GL app, without Unity post processing stack GitHub dependencies.

Verdict

Early project with 12 stars and 1.0% credibility score signals low maturity—expect rough edges despite solid README and AUR/Nix packaging. Try it for fun on kitty if you're shader-curious; skip for production unless you need terminal post-processing now.
