Title card on white. A pill reading Alternatives, the title AionUi alternatives, the line 5 apps for running teams of AI agents and a Checked 9 Nov 2026 line. Five small tiles named Orca, Munder Difflin, OpenWork, Claude Cowork and Paperclip slide in under a grey tile labelled AionUi.

Our view: Orca is the closest AionUi alternative, because it is also a free desktop app that runs Claude Code, Codex and other agent CLIs side by side. AionUi is a free, Apache 2.0 desktop app for macOS, Windows and Linux, with a WebUI and a Team mode, and it stays a strong pick. Checked 9 Nov 2026.

Munder Difflin is free and open source: a desktop app that runs a team of AI agents for all kinds of knowledge work, coding included, on your own computer. More head to heads live in our Comparisons hub and Herdr alternatives.

What is AionUi?

AionUi is a free, open source desktop app where AI agents do work on your computer. Its README, read 9 Nov 2026, calls it “a Cowork platform where AI agents work alongside you on your computer”. It has its own agent and also detects the CLIs you already have. The repo description names “Claude Code, Codex, OpenCode and 20+ more CLI Agent”.

It runs on macOS, Windows and Linux. Its WebUI mode opens it “via browser from phone, tablet, or any computer”, and chat integrations for Telegram, Lark, DingTalk and WeChat do the same job. The licence is Apache 2.0. The latest release, v2.2.2, came out on 9 Sep 2026, and commits kept landing through 5 Nov 2026. The repo had 34,156 stars on 9 Nov 2026. Stars measure interest, not use.

How does AionUi Team mode work?

A Leader agent splits your request and hands the parts to Teammate agents. The README says the Leader “receives your instructions, breaks them into subtasks, and delegates to Teammate agents”. Teammates “share results through an async mailbox, and write to a shared task board.” One detail matters for parallel work: “all agents share the same folder”.

Animation. On a white background, a green watering can tagged Leader tips over a long wooden planter box labelled Same folder. Water falls on a row of seedlings tagged Teammate, and each one grows a leaf in turn. Tapping the watering can tips it again and the seedlings grow another leaf.
In AionUi's Team mode a Leader hands subtasks to Teammates, and all agents share the same folder, per its README, read 9 Nov 2026.

Why look for an AionUi alternative?

Mostly to compare tools like AionUi before you pick, and three facts can tip it. Slack and Discord are listed as “coming soon”. Team mode puts every agent in one folder, and we think some teams will want files kept apart. And no release has shipped since 9 Sep 2026, though commits go on.

What are the best AionUi alternatives?

Orca, Munder Difflin, OpenWork, Claude Cowork and Paperclip. Every row was read on 9 Nov 2026.

1. Orca: the closest match

Orca is a free desktop app that runs several agent CLIs at once. Its README, read 9 Nov 2026, says “Run Claude Code, Codex, and any other coding agent in parallel, each in its own worktree.” One agent can also lead: “It splits the work, starts worker agents in their own workspaces”. The Orca site answers “Is it free?” with “Free and open source.” It suits people whose agents mostly write code. See Orca vs Munder Difflin.

2. Munder Difflin: a team for all kinds of work

Munder Difflin is ours, and like AionUi it covers more than code. Agents run while your computer runs. Its README, read 9 Nov 2026, describes “A GOD orchestrator you talk to. It routes tasks, adjudicates traffic, and escalates only what needs a human.” Agents run on engines such as Claude Code, Codex and Gemini CLI, take work from Slack or a webhook, and add tools through MCP servers, skills and plugins. A Cloud Office and a mobile app are coming soon. It suits mixed work: research, writing, ops and code. Setup is in how to install and use Munder Difflin.

3. OpenWork: the Cowork style desktop app

OpenWork is a desktop app where agents work on your own files, built on OpenCode. Its README, read 9 Nov 2026, calls it “the free, open-source alternative to Claude Cowork and Codex”. The desktop app is MIT licensed; the team control plane has a separate EE licence. Its pricing page, read 9 Nov 2026, lists Free at $0 for “up to 5 users” and Team at $10 per user a month. It suits teams that share skills and MCP servers.

One more cushion drops in, and a bigger green boat labelled Team $10 per user a month glides alongside to take it. Tapping the small boat rocks it and the cushions settle again.
OpenWork lists Free at $0 for up to 5 users and Team at $10 per user a month, per its pricing page, read 9 Nov 2026.

4. Claude Cowork: Anthropic’s own

Claude Cowork is Anthropic’s agent for office work. Its help page, read 9 Nov 2026, says “Claude’s work runs on Anthropic’s servers, in an isolated environment”. It needs a paid plan: Pro, Max, Ultra, Team or Enterprise. On 9 Nov 2026, Anthropic’s pricing page listed Pro at $20 a month billed monthly, or $17 a month billed yearly. AionUi’s README calls Cowork “macOS Only”; the help page now lists Claude Desktop for macOS, Windows and Linux (beta). It suits people who want one vendor and no setup.

5. Paperclip: if you run agents like a company

Paperclip is a self hosted server that runs a team of agents as a business. Its README, read 9 Nov 2026, says it “orchestrates a team of AI agents to run a business”. It adds: “Open source. Self-hosted. No Paperclip account required.” The licence is MIT, v2026.1106.0 came out on 6 Nov 2026, and Paperclip Cloud has a waitlist. It suits people who track agents against goals and budgets. See Paperclip alternatives.

How to choose

Our view: pick by the shape of your work.

  • Orca for the closest swap: one desktop app, many agent CLIs, a worktree each.
  • Munder Difflin for a team of agents on research, writing, ops and code, run from one orchestrator.
  • OpenWork if your team wants a Cowork style app with shared skills and MCP servers.
  • Claude Cowork if you already pay for Claude and want Anthropic to run it.
  • Paperclip for goals, budgets and an org chart around your agents.
  • AionUi itself if Team mode, the WebUI and Telegram or WeChat access fit how you work.
