  • How I Built a Scalable, Free URL Shortener.
    Building a URL shortener from scratch? Nah, you’re crazy! Instead, we grabbed a trusty open-source solution that’s already been battle-tested. By using this ready-made tool, we skipped the drama of starting from zero and cut our development time way down. This gave us more time to focus on making our app and management system even better—plus, it saved us from pulling out our hair! - Source: dev.to / about 2 years ago
  • Show HN: An open-source alternative to Bitly
    Last big project at my old job was for an appointment notification service. In addition to making messages longer and thus costing us more, counterintuitively the unshortened URLs got flagged as spam by automated systems and end users more than shortened. However, you can’t use bitly or other free/public shorteners; use one hosted on your own domain. I used shlink https://shlink.io/. - Source: Hacker News / about 2 years ago
  • Copying microsofts aka.ms links with our internal Dns to help stop phishing
    IF you just want to setup an internal link shortener, there is software out there for it. We do it at my company. The best one I've found is Shlink: https://shlink.io/. Source: about 3 years ago
  • Shlink CLI issue
    I have just set up shlink.io via /r/portainer and docker-compose. Now I have tried opening the CLI to generate an API key which I need for the shlink web interface but unfortunately it closes in a fraction of a second after bin/cli, showing all available arguments. Source: about 3 years ago
  • Permanent URL to file possible?
    Are you looking for stable HTTP/S URLs that you can publish for others to access? One solution to that might be to purchase your own domain and host a little redirector service that bounces the consumer to the real, currently active, cloud URL. Something like https://shlink.io/ might work (but I’ve not used it, and that’s just a suggestion not a recommendation!). Source: over 3 years ago

  • Banana.dog back from the dead
    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
