Ah, no, license doesn’t expire, it’s lifetime. The period for installing app updates expires. You don’t need to renew it if you don’t want latest versions.

What shocks me when comparing Kerlig vs. LocalCan is the revenue per website visit:

Kerlig = $0.16 / visit
LocalCan = $0.86 / visit

and I think Kerlig needs to pivot!

Developers need great tools with top DX, period.

This is as true now as it was back in 2023 when LocalCan only allowed publishing .local domains on the local network.

TCP tunnels open a whole bunch of new possibilities when developing: K8s clusters, gRPC services or exposing local database

Enjoy!

Thanks! Self-signed certificates are for .local domains only, public URLs use LetsEncrypt.

huge milestone today – it all started as side projects on my laptop – now my apps have crossed $100k in revenue!

I've made several pivots in my life, but this one is definitely the most challenging, ambitious and rewarding so far

now back to work

It feels almost magical when the AI occasionally picks some nuggets like "since you are an INTJ, you will..." or "...will be useful when visiting Canary Islands"

I've created a "Me" preset for hyper-personalized AI responses in Kerlig.com – just a few paragraphs about who I am, what I do, my plans, and goals.

Those lessons would be a disaster if they happened to a paid product used by thousands of customers. But here, the goal was to sharpen the skills!

- building web apps with Next.js and WebSockets
- mitigating DDoS attacks on WebSockets using the Cloudflare API
- properly using transactions in Postgres to avoid deadlocking the whole database
