Trigger Webhooks from Postgres
We just released a small open-source tool which enables you to fire HTTP requests from Postgres triggers. One of the things we’re using it for now is to send Slack messages when a new user is created and wanted to see what the community thinks as we explore more use cases!
Trigger Webhooks from Postgres launched on February 2, 2023 with 8 votes, #1,489 of 3,829 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 3 years on.

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
