OpenWrt Router Gets Tiny Failover Tool for 8MB Flash
A developer built wanmon, a lightweight failover controller for OpenWrt routers with only 5.7MB of writable flash. The tool monitors latency, packet loss, and jitter to automatically switch to a backup connection. It uses shell scripts and a minimal web interface, consuming under 100KB of storage.

Wanmon solves a real constraint for low-end routers where mwan3 is too heavy, but its niche appeal limits broader impact.
