About this list

Each row groups settings that serve a similar user goal, while keeping the exact name used by each project. “Not listed” means this settings catalog has no matching row; it is not a universal claim that the software cannot do it.

Settings catalog checked through 2026-08-31.

Car search uses comma’s pinned stock openpilot capability table. A fork setting does not confirm exact-car support. Check the exact year, package, hardware, and fork documentation before installing.
