jcode

jcode is a terminal coding agent from Solo Systems. It is described as a harness for agent work, with an emphasis on extracting more useful work from the model core through the surrounding harness rather than from the model alone. The page says it is intended to be a general-purpose dev tool for day-to-day work, and it also frames the project around advancing agent intelligence.

The product description highlights memory, agent swarms, and parallelism as part of its approach. It says scaling test-time compute through agent swarms can help, that speed comes from parallelism, and that continual learning is addressed through memory. The page also mentions side panels and background tasks in its summary text, and calls the project a fast, memory-equipped coding agent. A section titled jcode bench discusses standard evaluations of agent harnesses and argues that common benchmarks can misrepresent what agents can do because of leakage, hidden test sets, timeouts, and coarse scoring.

jcode is available for macOS, Linux, and Windows. The page includes an installation command using curl and bash, and it links to GitHub. It says the project publishes everything publicly and will remain open source and open research.
