OpenWrt is a Linux operating system for embedded devices, commonly wireless routers. Its writable filesystem and optional package management let users customize devices by adding packages; the project lists more than 27,000 packages and services. Configuration is available through an SSH command-line interface or a web interface, and the Table of Hardware helps check device support before installation. Hardware capacity is a key consideration: OpenWrt identifies 8 MB flash and 64 MB RAM as bare minimums, while warning against devices at those limits for current, secure use. The downloads page lists OpenWrt 25.12.5 as the current stable release and describes development snapshots as generally untested. The older 24.10 release is slated to receive limited security and bug fixes for some time. OpenWrt is free software, with no subscription or licensing fees. The project says users should know GNU/Linux and basic networking concepts before installing it; voluntary support from developers and users is not guaranteed.
