Nimbalyst Alternative

An independent comparison of Nimbalyst and the field

An open-source alternative to Nimbalyst for the whole company

Nimbalyst runs Claude Code and Codex in a visual desktop workspace. Kortix is the open-source alternative for teams whose agents reach past the code editor: agents, skills, memory and connectors live in one git repo you own, and every session runs on its own cloud computer.
