1code

1code is an open-source desktop client designed to streamline how developers work with AI coding agents. It provides a unified interface for interacting with multiple backends, currently supporting Claude Code and Codex, so users can easily switch between models and choose the one best suited to a specific task. The primary purpose of 1code is to make AI-assisted development more efficient, consistent, and accessible within a single, well-designed application.

Key features include side-by-side and switchable model sessions, allowing developers to compare outputs, iterate quickly, and adopt the best solution from each AI. The tool offers a focused coding environment with syntax highlighting, multi-file context support, and structured conversations tailored to programming workflows. Users can manage prompts, review model responses, and refine instructions without leaving the client, reducing context switching between browser tabs and tools. As an open-source project, 1code is extensible and transparent, enabling teams or individual developers to adapt it to their own infrastructure or preferred AI providers.
