Pretty simple setup, but it works well for this use case

Hi HN,I often run into systems that can send email but cannot call a webhook directlyI built a tool that creates an opaque email address <mailboxId>@hook.echovalue.dev and forwards inbound messages as structured JSON to a configured endpoint. It can also call a webhook from a cron schedule, so small scheduled jobs do not need their own workerThere are built-in formats for Slack, Discord,...

Hi HN,I built this while helping a colleague migrate away from Outlook for Mac after a company acquisition. Outlook only exports contacts as .olm, and most tools we found were either paid or required uploading the data somewhereSince emails and contacts are a pretty sensitive topic, I didn’t like that, so I put together a small local tool insteadIt extracts contacts from an Outlook for Mac .olm...

I built this JSON linter because, while there are plenty of great ones out there, I wanted something that fits my needs—ad-free, no tracking, privacy-focused, and lightweight. What started as a quick “1-hour project” quickly spiraled into a more "complex" challenge.Initially, I used a simple <textarea>. It was easy, fast, and functional, but I wanted code highlighting for better...
The concept of 'storing a map as JSON' in a serverless context usually translates to saving or reading a file in a bucket, like S3 or GCS, but then again, this brings us back to waste time installing and managing an SDK.
Got your point, and for larger projects, a more structured approach definitely makes sense. However, I often find myself needing something like this, so I went ahead and built it.
