jcode Builds a Custom Harness for AI Coding Agents

jcode is a Rust-based harness for coding agents that focuses on multi-session development workflows, deep customization, and fast local operation. It gives developers a configurable environment for running AI coding assistants across projects and tasks, with installation scripts for macOS, Linux, and Windows. The project targets users who want more control over agent behavior, sessions, and tooling than a single chat-style interface usually provides.

jcode Builds a Custom Harness for AI Coding Agents

jcode is a Rust project for running and managing AI coding agents. It focuses on multi-session workflows, configurable behavior, and performance for developers who spend long stretches working with agent-assisted coding tools.

Why it stands out

The project positions itself as an agent harness rather than a single assistant. That means it aims to coordinate sessions, tools, and preferences around real coding work.

Quick start

Install scripts are available for macOS, Linux, and Windows, making it easy to test in a local development setup.
