I tried Next.js + Postgres + Vercel and here's what actually happened

I sent the same link to three Slack channels last Tuesday and realized I had zero way of knowing which one drove the 47 signups I saw that morning. Honestly, it was a bit of a wake-up call - I had been relying on guesswork to optimize my outreach efforts. Look, I know it sounds silly now, but I had been using a simple curl command to shorten my links, without any real insight into how they were performing. Why curl wasn't enough I was using curl to shorten my links, and then sharing them across different channels. But the problem was, I had no way of tracking which links were actually driving conversions. I could see the overall number of signups, but I had no idea which specific link was responsible. I tried using requests in Python to fetch the link metrics, but it was a bit of a hacky solution. The thing is, I was trying to solve a problem that wasn't really solvable with just curl and requests . I needed a more robust solution that could give me real-time insights into my link perf
