I’ve been using OpnSense/pfsense [0] for years and would highly recommend it. It has a great automatic update experience, config backups, builtin wireguard tunnels and advanced features like packet filtering options like suricata.
When I am doing network management on my weekends, I’m so glad I’m not stuck in the Linux terminal learning about networking internals and can instead just go to a webui and configure my router.

Project mention: 2026 Best PHP Micro Frameworks: Slim, Flight, Fat-Free, and More! | dev.to | 2026-01-03
In conclusion, for 2026, Flight PHP is my top pick—and not just because I maintain it. Its speed, simplicity, and rapid evolution make it the ideal micro framework for everything from hobby projects to production beasts. Slim remains a safe, reliable choice, and F3 is great for feature-rich needs. If you're starting fresh, try Flight v3; the docs are polished, and the community is welcoming. Give it a go or drop in on the Matrix or Discord chat!

If you've ever used Saloon PHP, you know the feeling: one class per API, one class per endpoint, everything typed, testable, readable. No magic annotations. No generated files. Just clean OOP.
