CodeAlta

CodeAlta is a desktop workspace for agentic coding on your local projects. A terminal UI is available too.

🚀 Install

Install .NET 10, then install CodeAlta Desktop, the app we recommend:

dotnet tool install -g CodeAlta
alta

CodeAlta TUI runs the same agents in a terminal. You can install both:

dotnet tool install -g CodeAlta.Tui
altatui

Launch the app from a project folder. On first launch it opens the provider setup: sign in with a ChatGPT or GitHub Copilot subscription, or add an API key.

See Getting Started for requirements and the first steps.

✨ Features

• A desktop app, and a terminal UI: CodeAlta Desktop has session tabs you can drag and split, a code editor, terminals and git changes for your projects, and every setting in one window. CodeAlta TUI is a keyboard-first terminal UI. Both share the ~/.alta profile, so a session started in one can be continued in the other. See how they compare.
• Sessions on your projects: sessions are saved on disk. Queue prompts, steer a running turn, and let a session delegate tasks to child sessions.
• Worktrees: a session can work in its own git worktree, on its own branch, so that several sessions change the same project at the same time.
• Automations: in CodeAlta Desktop, a prompt can run on a schedule, when an issue or a pull request is opened, or on demand.
• UI tools and MCP server: in CodeAlta Desktop, an agent sees and drives the window, and other applications do the same through its MCP server.
• The models you already have: subscriptions and API keys for OpenAI, Anthropic, Google, Mistral, xAI, Azure OpenAI, and OpenAI-compatible servers, and Claude Code through the CLI you installed.
• Everything the agent does: tool calls, file diffs, and context usage are in the timeline. In CodeAlta Desktop a tool call opens with its output in a live terminal, or with the file or the diff it worked on.
• Extensions: agent prompts, MCP servers, skills, and trusted local .NET plugins, which an agent can write and reload while CodeAlta Desktop runs.
