Here we go again. Built a simple site monitor for my customers and me. Uptime, DNS, certs and headers in PHP with no deps. One alert per server. Call it Vaka - Keeps watch while you sleep 🦉 Went open source right away this time. Did I miss something? github.com/webready-se/vaka

And here is the story behind it jarnesjo.com/writing/vaka-se…
Vaka - self-hosted site monitoring with one alert per server

Vaka - self-hosted site monitoring with one alert per server

When a server goes down I want one message, not one per site. So I built Vaka. Uptime, certificates, domains, exposed files and security headers in PHP and SQLite. Open source.

Sidoprojektet Odlingsguiden har vi nu lagt till blommor, men även fröfilosofi som jag tycker alla borde läsa, lillabosgarden.se/odlingsgui… Visste du att fem företag kontrollerar 95% av världens grönsaksfrö?

Wrote about how I did my dark mode toggle with vanilla js instead of using Ract or next-theme for example jarnesjo.com/writing/three-w…

One of the best feature so far and highly appreciated is shareable dashboards - token-based read-only links (/?share=<token>) so the customer can easy see and share data internally

Don't do like me and bang your head into the wall by running artisan commands on stale code when using Laravel Forge zero deployment 😬 jarnesjo.com/writing/stop-ru…
Stop running artisan on stale code

Stop running artisan on stale code

A small shell function that warns you when your current directory no longer matches the active deploy. Saved me from debugging phantom issues after a Forge deploy.

I got tired of Google Analytics so I built Puls. Cookieless, lightweight analytics in a single PHP file and SQLite. No frameworks, no dependencies, no build step. Drop it on any PHP host and go. And it's open source. I wrote a bit about it here: jarnesjo.com/writing/puls-co…

Puls - cookieless analytics in a single PHP file

I got tired of cookie banners and bloated analytics tools. So I built my own. One PHP file, SQLite, no cookies. Open source.

Built a simple cookiefree analytic for my customers and me. So tired of Google Analytics and bit stingy 😬 Call it Puls — One file. No cookies. Full picture. Should I release it open source?

Also added check for different status checks for example 404 and 301 to keep an eye on

One thing I was really curious about was the bot traffic. For example, I've seen that Claude Code authenticates itself via axios and doesn't load javascript or images. So there's nginx cofig to keep an eye on that if you want too
