We build intelligent systems.
An always-on personal agent. Coming soon.
An autonomous pen tester. Coming soon.
An open-source AI coding agent for the terminal, and the flagship Solo Systems product. Jcode is a next-generation coding agent harness built for multi-session workflows, infinite customizability, and performance: 14ms boot, tiny memory footprint, semantic memory, background tasks, swarm multi-agent coordination, and self-development tooling that lets the agent modify its own harness.

An always-on personal agent. Rather than waiting for prompts, System 0 runs continuously in the background of your digital life: watching inboxes, calendars, and feeds, surfacing what matters, and acting on routine work before you ask. It is built on the same agent harness that powers jcode, with the same emphasis on efficiency and durable memory. Coming soon.
An autonomous penetration tester that probes systems the way a human red team would: reconnaissance, exploitation, lateral movement, and reporting, executed end to end by an agent that documents every step it takes. Built for teams that want continuous security validation instead of an annual audit. Coming soon.
Solo Systems (Solo Labs, YC S26) builds intelligent systems: software agents that work alongside you in the terminal, in the background, and across your infrastructure. Everything we ship is engineered for performance and built to be customized. Reach us at jeremy@solosystems.dev.
