Choosing a Soft Router OS

I have used OpenWrt, Gaoke, iKuai, pfSense, and OPNsense for a while. Here is a practical comparison.
OpenWrt
- Lightest system; can be as small as 5 MB
- Fully open source (especially if you compile it yourself)
- Rich ecosystem; best extensibility
- Medium usability; many settings require experience
- Fast updates and security patches
Gaoke / iKuai
- Chinese systems, free for personal use
- Closed source; backdoor risk depends on vendor (iKuai has been accused of mining backdoors)
- Great traffic control at Layer 7, with app-based QoS
- User-friendly; good for home users
- No IPv6 support
- Traffic control is CPU heavy and can cause ping spikes
pfSense / OPNsense
- Same lineage; both open source and mostly interchangeable in configs
- Enterprise grade with security features (traffic inspection, virus scanning)
- Strong firewall; solid IPv6 capabilities
- Very powerful, good for advanced users
- Complex configuration, even more than OpenWrt
- Very stable
- Good extensibility with built-in plugin store
- Good traffic control at Layer 3
- Medium CPU usage for traffic control
Home use summary
| System | Stability | Security | Resource Use | Ease of Use | Professional | Extensibility | IPv6 Support |
|---|---|---|---|---|---|---|---|
| OpenWrt | Medium | Medium-High | Low | Medium | Medium-High | High | Medium |
| iKuai / Gaoke | Medium | - | High | Medium-High | Low | Low | None |
| pfSense / OPNsense | High | High | Medium | Low | High | Medium | Medium-High |
Network design tips
- For the primary home gateway, choose stability and security first.
- If you need traffic shaping, try pfSense or OPNsense (beginners can start with iKuai / Gaoke).
- For rich features, consider OpenWrt as a bypass router.
- If you need IPv6 firewalling, go with pfSense/OPNsense. OpenWrt is not recommended.
