Helios · Open source
Coding agents,
one Linux desktop.
Bring Claude Code, Codex, Gemini, Muse, Kimi and OpenRouter into one native workbench. Keep conversations, previews, the terminal and Git changes beside your project.
Free, MIT-licensed software. Provider accounts or API usage are separate.
Your choice of agent
Six ways in. One place to work.
Helios connects to each provider through its own integration. Models, sign-in and available controls depend on that provider.

The demos and feature guide show the current release. The default APT channel may carry an earlier version. Choose the right install channel.
From request to reviewed change
Stay with the work.
Keep the controls close.
Choose a model and the reasoning and permission options supported by that provider. Review native approval requests when they are available, and keep the task’s goal and plan beside the conversation.
Look at what changed.
Open a local preview in the browser pane, run a command in the terminal, and inspect the Git diff. Use checkpoints, a fork or an opt-in worktree when the next step needs its own space.

Start with one provider and one folder.
The current release is available as an Ubuntu Debian package and source code. The install guide explains the latest release, the stable APT channel and your first chat.
Already using a coding CLI?
Helios adds a native desktop around it. Your provider still handles model access and billing; you still choose what the agent can do.

Learn the whole workflow
One guide, from setup to recovery.
Search practical instructions for every provider, the conversation controls and each workspace pane. Find the setting, shortcut or recovery step you need without leaving the project website.
Open the user guide →Local application, connected agents
Your work stays understandable.
Helios keeps its own settings and work state locally and sends no telemetry. Connected providers receive the prompts, context and tool results their sessions need. Permission behaviour, usage reporting and billing vary by provider.
Permission controls are useful guardrails; they are not a universal sandbox or a guarantee of your provider’s bill.

A few useful answers.
Is Helios free?
The application is free and open source under the MIT licence. Provider subscriptions and API charges are separate; installing Helios does not include model access.
Does it run on Linux, Windows or macOS?
Helios is a native Linux application built with GTK4 and libadwaita. Ubuntu 26.04 is the packaged and tested route. Other Linux distributions can run from source with the required libraries. Windows and macOS packages are not published.
Is this a Claude Code or Codex GUI?
Yes. Helios provides a desktop interface for Claude Code and OpenAI Codex, alongside Google Antigravity, Muse Code, Kimi Code and OpenRouter. It uses distinct provider integrations, so controls and capabilities differ.
Can I keep using my existing terminal?
Yes. You can continue to use the provider CLIs directly. Use the terminal for scripting and headless work; use Helios when the desktop’s session list, preview and review tools help you follow a task.
