AionUi

What is AionUi?

AionUi describes itself as a free, local, open-source 24/7 cowork app designed for CLI-based AI coding agents. According to the project's README on GitHub, it supports Claude Code, Codex, OpenCode, Gemini CLI, and over twenty more CLI agents. The tool provides a graphical interface that runs alongside these agents, letting developers monitor agent activity, interact with agent output, and manage multiple agent sessions without leaving the desktop. The project's website states that the app is intended to run locally on the user's machine — there is no mention of a cloud-hosted version. The GitHub repository shows 30,938 stars, which indicates a relatively high level of public attention, though star counts alone do not reflect active usage or maintenance frequency.

The tool is positioned primarily as a productivity companion for developers who rely on AI coding assistants in terminal environments. Rather than replacing CLI agents, it adds a persistent UI layer that stays open around the clock. The repository documentation emphasizes that AionUi is "local and open-source," meaning no data is sent to external servers unless the user configures it otherwise. There are no claims in the documentation about compatibility with proprietary services beyond the listed agents.

Who is AionUi for?

Based on the tool's description and listed integrations, AionUi targets developers who use multiple AI coding agents in their daily workflow and want a unified desktop presence for them. This includes individual developers, research teams, and small engineering groups that rely on agent-based tooling for code generation, debugging, or automated refactoring. The documentation does not mention enterprise features like role-based access control, audit logging, or centralized administration — so the tool appears aimed at individual users or small teams working locally.

Users comfortable with command-line interfaces and open-source self-hosting will find the setup straightforward. The 24/7 cowork concept implies the app stays running in the background, collecting agent output and allowing asynchronous review. Developers who prefer a single terminal window and manual agent invocation may find the added UI redundant.

How much does AionUi cost?

The pricing model is listed as free, with a starting price of $0 per month. There are no paid tiers or subscription plans described on the website or repository. The project's GitHub page carries an open-source license, and the website does not offer any paid upgrades or premium features. Users who wish to contribute beyond usage can participate via the public repository — the project accepts issues, pull requests, and community support. There is no indication that the tool collects payment information or requires an account to download or run it.
