jcode
jcode is an open-source terminal coding agent — a Rust "harness" built by Solo Systems (MIT-licensed, 8,600+ GitHub stars within months of its January 2026 launch) whose whole design is to squeeze the most useful work out of whatever model you point it at. The model-access story is what sets it apart: bring your own API key, reuse a Claude or OpenAI subscription you already pay for via OAuth, or run fully local models through Ollama or LM Studio — so your code and your costs can stay on your own machine. Beyond a normal chat agent it adds persistent memory (it keeps learning your project across sessions), side panels, background tasks, and swarm coordination — running several agents in parallel to scale test-time compute on a hard task. It speaks MCP, ships its own open "jcode bench", and installs with a single command on macOS, Linux, or Windows.
