Top 9 C Compositor Projects

Compositor

  1. sway

    i3-compatible Wayland compositor

    Project mention: Hard numbers in the Wayland vs. X11 input latency discussion | news.ycombinator.com | 2025-01-26

    > basically no good if you're any different from the people who hacked it together.

    Why would you expect it any different? How can one implement things that they have no need or no hardware for? The entitlement is a bit jarring.

    Also I think they merged something last year: https://github.com/swaywm/sway/pull/7681

  2. InfluxDB

    InfluxDB high-performance time series database. Collect, organize, and act on massive volumes of high-resolution data to power real-time intelligent systems.

  3. picom

    A lightweight compositor for X11 with animation support

    Project mention: I found an 8 years old bug in Xorg | news.ycombinator.com | 2024-06-23

    Picom has an awesome feature [0] that, for the sake of all our eyes, should come by default on every device with a screen. It can continuously adjust the brightness of individual windows by averaging all the pixels in that window. It's great for defending against "flashbangs" (when a new tab burns your eyes with a blank white screen).

  4. swayfx

    SwayFX: Sway, but with eye candy!

    Project mention: scenefx: a drop-in replacement for the wlroots scene API | news.ycombinator.com | 2024-08-01

  5. cage

    A Wayland kiosk

  6. cagebreak

    Cagebreak: A Wayland Tiling Compositor Inspired by Ratpoison

    Project mention: The Future Is Niri | news.ycombinator.com | 2025-03-12

    I still use ratpoison, dreading the day it stops working for whatever reason (wayland being a likely one). Haven't tried it, but Cagebreak (https://github.com/project-repo/cagebreak) seems like a possible successor.

  7. open-display-transform

    Open Display Transform is a collection of tools and experiments for rendering wide-gamut scene-linear data into an image for an SDR or HDR display device.

  8. sway-borders

    Fork of sway with some extra features, mainly related to borders.

  9. CodeRabbit
