About Mirafold
Mirafold is a powerful, open-source generative UI built specifically for terminal coding agents such as Claude Code, Codex, and Gemini CLI. It acts as a faithful browser interface that leverages your existing engine, settings, memory, and permission rules while transforming raw terminal outputs into rich, interactive elements.
Instead of dealing with plain text, responses are rendered using 18 live components that include formatted text, live charts, tables, and graphs—all of which you can pin for quick reference. Its Mission Control feature organizes your entire fleet of sessions onto a single grid. Additionally, Mirafold allows you to securely pair your phone using a QR code via end-to-end encryption (available through a paid hosted relay or self-hosted option). Running directly on your machine and licensed under the MIT license, Mirafold bridges the gap between terminal workflows and modern web UI.
