24 alternatives to Internet.nl – test tool for modern internet standards
For the past months we've been working on making our open source tool Internet.nl easier to deploy and develop on. Last week we release version 1.8.0 (https://en.internet.nl/article/release-1.8/) which includes these changes. Tests include: IPv6, DNSSEC, HTTPS/TLS, various security options like XSS, CSP headers, security.txt, RPKI, DMARC, DKIM, SPF, STARTTLS, DANE for web/email, and a browser connection test for IPv6 and DNSSEC. (see: https://en.internet.nl/faqs/) Using Docker & Docker Compose it is now trivial to deploy your own…
Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Prices are shown for the 1 we have checked on their own sites, 1 of them free or with a free tier. Internet.nl – test tool for modern internet standards launched in 2023; newer entries below may have overtaken it.

Yes, it's open source: https://github.com/lissy93/web-check :) Why I'm building this? There are a lot of tools out there for discovering meta and security data relating to a website, IP or server. But currently, there isn't anything that does everything, all in one place and without a paywall/ user sign up. It's still a WIP, and I'm working on a new version, with some more comprehensive checks, so any feedback would be much appreciated :)

I built a DNS resolver that lets me use https://frontend.numa instead of localhost:5173 — auto-generated TLS certs, WebSocket passthrough, path routing. No mkcert, no nginx, no /etc/hosts.

Howdy HN! I find myself testing my ping from time to time, especially when my internet seems wonky while WFH. It feels like there should be an easier way test my ping than puling up a terminal or a complex web app - especially when I'm on my phone or any other device that doesn't have a terminal. I figured I should be the change I wish to see in the world and created this super light ping test. I also created a latency monitoring solution (https://github.com/cjjeakle/network-monitor), feel free to clone and try it out! I know there are a lot more mature monitoring…

Local development with .local domains and HTTPSfree tier, from $8/mo▲84Hi HN! I'm Jarek, and I've built this tool that allows publishing .local domains on the local network using mDNS. It also has a reverse proxy that handles HTTPS termination and port forwarding. I'm working on adding more features, like an index page with all available domains or allowing proxy redirects, so you could redirect from HTTP to HTTPS. Let me know if you have any questions or feedback!

Hi! I am sharing this because it may be useful to others. I created a simple Docker image that lets you easily expose a web app running locally on your dev machine to the Internet, via a proxy server. It is a self hosted alternative to something like Ngrok, which is a paid service if you use custom domains. A small server is cheaper than Ngrok (I use Hetzner Cloud and the cheapest server costs me 3€ per month). I use this method in particular to test HTTP verification with Let's Encrypt for a SaaS app running on my Mac. Hope this is useful :) Code:…

This is a proof of concept utility which allows you to expose local services to the internet at large: https://github.com/skx/tunneller In short it is a simple ngrok alternative, which you can self-host. Because it is a proof of concept it hasn't been tested extensively, but it seems like it will solve my immediate-needs. Of course it needs test, and structure added. But feedback can't hurt :)
