A fast, lightweight code editor. No accounts. No ads. Free forever.
Kodo is built by KerbalMissile and SS-YYC around a few simple ideas: your editor should stay out of your way. Quick setup, syntax highlighting via extensions, and zero friction from launch to coding. We want to make coding human again; no bloat, but still a good user experience.
v2.1.0 is here - Native Linux support (x64 and ARM64), independent hotfixes with verification and rollback, a completely rewritten cross-platform updater, and language-server support - still around ~87% lighter than VSCode with no extensions installed.
Released under the GPL-v3.0 license.
