0sec Labs Open-Sources 0, an AI Security Harness With Web UI, CLI and MCP

Zurich-based 0sec Labs has released 0, an MIT OR Apache-2.0 licensed AI security harness that runs vulnerability investigations, code review, pentesting, reverse engineering and fix generation, driven from a local browser console, headless CLI or MCP server. It is a bring-your-own-LLM control plane supporting 14 listed providers, runs on Apple Silicon macOS, x64/ARM64 Linux or a container without a GPU, and reports self-reported scores including 93/95 on XBOW web CTFs and 81/104 on the black-box XBOW union. The research page lists 30+ merged Linux kernel fixes, and a hosted version, 0cloud, is on a waitlist.
