Kortix vs Nimbalyst: an open-source company system or a coding workspace?

Two open-source tools, two different jobs

Nimbalyst is an open-source desktop workspace that runs Claude Code, OpenAI Codex and other coding agents on your own machine, with visual editors for the markdown, diagrams, mockups and data models around the code (Nimbalyst features). It keeps the coding agents you already pay for and wraps a working surface around them.

Kortix is the open-source AI Operating System: your agents, their skills, your company memory, and every connector in one git repo you own, with the agents working on real cloud computers. Where Nimbalyst wraps the agent, Kortix runs the agents and the rest of the company's work from one repository.

What Nimbalyst does well

Nimbalyst runs several coding sessions at once, each optionally isolated in its own git worktree, and tracks them on a kanban board. Every AI edit arrives as a red and green diff you accept or reject, and the editors cover markdown, Mermaid, Excalidraw, mockups, spreadsheets and code. It is free for individuals, with Teams at $20 per seat per month, per the Nimbalyst pricing page, checked October 2026.

For one developer directing Claude Code and Codex, or a small team that wants that in a shared workspace, Nimbalyst is a well-built tool. Its own site states the desktop and iOS apps are open source (Nimbalyst features).

What Kortix does differently

1# kortix.yaml2default_agent: ops-morning3agents:4  ops-morning: { connectors: [slack, stripe] }

Kortix holds the agents, their skills, the company memory and every connector in one git repo you own, and a short kortix.yaml declares how a session boots. One isolated sandbox per session. Each session has its own isolated machine and branch. Thousands of agents in parallel on one config, each on its own cloud computer.

Session work reaches main through a change request a person reads as a diff, and merge is default-deny for agents. The same repo wires the tools: 3,000+ apps in a click, plus MCP, OpenAPI, Postman, GraphQL and raw HTTP. Connector credentials are brokered server-side and never enter the machine.

Where each one wins

Nimbalyst wins when the job is code and the agents run on your own machine: it steers the exact coding agents many teams already pay for and gives diff review and parallel sessions that a terminal alone lacks. Kortix fits when the agents have to reach past the code editor and a whole company's work has to live in one place a team owns. For the full write-up, read Kortix vs Nimbalyst.
