CodeAlta

CodeAlta

CodeAlta is a workspace for agentic coding on your local projects, in a desktop app or a terminal UI.

🚀 Install

Install .NET 10, then install one of the two apps, or both:

# CodeAlta Desktop
dotnet tool install -g CodeAlta
alta

# CodeAlta TUI
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

• Two apps, the same agents: CodeAlta Desktop has session tabs you can drag and split, a code editor 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.
• Sessions on your projects: sessions are saved on disk. Queue prompts, steer a running turn, and let a session delegate tasks to child sessions.
• The models you already have: subscriptions and API keys for OpenAI, Anthropic, Google, Mistral, xAI, Azure OpenAI, and OpenAI-compatible servers.
• Everything the agent did: tool calls, file diffs, and context usage are in the timeline and open with their details.
• Extensions: agent prompts, MCP servers, skills, and trusted local .NET plugins.
