# Open-source Nimbalyst alternatives, compared lane by lane

> A Nimbalyst alternative is a tool for teams whose coding agents need more than a desktop workspace. Kortix is the open-source AI Operating System we recommend: agents, skills, memory and connectors in one git repo you own, each session on its own cloud computer.

## Four ways to run coding agents, and what each leaves to you

Rival columns state what each rival's own site documents (checked October 2026); the sources are linked in the prose on this page.

| | Kortix (recommended) | Nimbalyst | Superset | Orca |
| --- | --- | --- | --- | --- |
| Open source | Yes. Read it, fork it, audit it. | Yes, the desktop and iOS apps. | No. The code is public to inspect. | Yes, the desktop app. |
| Interface | Web, desktop, mobile, CLI, Slack, Teams. | A visual desktop app; an iOS companion. | Desktop, CLI, SDK and an MCP server. | A desktop IDE; iOS and Android companions. |
| Agent harness | OpenCode is the harness. | Claude Code and Codex first; OpenCode in alpha. | Any CLI coding agent you bring. | Any CLI coding agent you bring. |
| Where agents run | Its own cloud computer, one per session. | On your own machine. | Your machine by default; add any host. | Your machine, an SSH host, or remote runtime. |
| Configuration | Files in one git repo you own. | Plain files inside your own project. | Scriptable; your own workflow stays. | The app's own worktrees and settings. |
| Best for | Teams running agents across the whole business. | A developer steering coding agents visually. | Scripting how many coding agents get work. | A desktop IDE for a fleet of agents. |

## What a Nimbalyst alternative changes

Nimbalyst is an open-source visual workspace for running Claude Code and Codex sessions in parallel, with editors for the markdown, diagrams, mockups and data models around the code ([Nimbalyst features](https://nimbalyst.com/features)). It steers the coding agents a developer already pays for, on that developer's own machine, and shows every AI edit as a red and green diff you accept or reject.

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. Nimbalyst stops at the editor; Kortix runs the agents too, each on its own cloud computer, and lands their work as a change request a person approves.

## The rivals worth comparing

Superset is one workspace for Claude Code, Codex and any coding agent, with each task in its own isolated git worktree ([Superset](https://superset.sh)). Orca is a desktop IDE that runs a fleet of agents side by side, each task with its own worktree, steered from a phone as well as a desk ([Orca](https://www.onorca.dev)). Conductor runs first-party Claude Code, Codex, Cursor and OpenCode agents in its own cloud sandboxes, driven from a Mac app, mobile, or its API ([Conductor](https://www.conductor.build)).

Each of those tools orchestrates coding agents well. None of them holds a company's agents, memory and connectors in one repository, and none runs each session on its own cloud computer.

## What Kortix adds on top

```
project/
  agents/      who does the work
  skills/      how a job gets done
  memory/      what it has learned
  kortix.yaml  rules, connectors, triggers
```

Kortix is open source: read it, fork it, audit it. One isolated sandbox per session means every session has its own isolated machine and branch. Session work reaches main through a change request, and merge is default-deny for agents. The repo also holds the connectors: 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.

Run it on Kortix Cloud, in your VPC, or on your own on-prem network. Self-host is free.

## How to choose

If your job is steering coding agents and reviewing their diffs, Nimbalyst is built for exactly that. If your job is owning the agents, the memory and the connectors across a company, Kortix is the one to evaluate.

## Questions people ask about the field

### Which Nimbalyst alternative should a team choose?

Kortix, when the agents have to reach past the code editor. The agents, their skills, the company memory and every connector live in one git repo you own, and each session runs on its own cloud computer.

### Are these alternatives open source?

Nimbalyst's desktop and iOS apps are open source ([Nimbalyst features](https://nimbalyst.com/features)), and Orca is open source ([Orca](https://www.onorca.dev)). Superset is not ([Superset](https://superset.sh)). Kortix is open source. Read it, fork it, audit it.

### Do these tools run the agents for me?

The rivals orchestrate coding agents on a machine you provide. Kortix runs the agents too: one isolated sandbox per session, each on its own isolated machine and branch.

### What does Kortix cost?

Free is $0 with 200 credits per month and 1 project. The team plan is $40 per seat per month with 2,500 credits per month per seat, pooled. Self-host is free.

## Run the whole company from one repo you own.

Kortix is free to start and free to self-host.

## Work that starts with nobody present

`kortix.yaml`

```yaml
# kortix.yaml
triggers:
  - slug: daily-digest
    type: cron
    cron: '0 0 9 * * 1-5'
    prompt: Summarize yesterday's support tickets and open a change request with the digest.
```

A trigger starts a session on a schedule or a webhook, and the session lands its result as a change request. From the kortix.yaml reference.
