The StartWrt port supposely adds some nice features, of which VPN chaining looks especially useful. And a better UI will make it more accessible. There are plenty of people out there who are willing to switch out their routers and chain VPNs to escape gov/ISP/big tech surveillance but don't have the technical means to do so. These are welcome improvements to reduce friction if they manage to pull it off.
The specs are not too bad for the price considering this is a startup project. It has 8 cores with per-core performance similar to Cortex-A55 + 4GB LPDDR4 + 16GB eMMC, which is better than most off-the-shelf routers. I wish they released the WIP schematics and code though, because there seems to be nothing at the moment.
