ZUHAL
Hi HN, I’ve been working on Zuhal, an email validation service designed for developers and marketers who need to ensure their emails reach real inboxes. Zuhal checks for syntax, domain validity, MX records, disposable addresses, and deliverability risks — all via a simple REST API or bulk upload. I built this because I faced deliverability issues with email campaigns and wanted a tool that’s fast, accurate, and affordable. I'd love to hear your thoughts, feedback, or suggestions for improvements. Also curious about how you handle email list hygiene in your projects or companies. Here’s the…

Email Validator by SidemailFeb 2026 · sidemail.io · ▲16Hi HN – Kristyna here. I built this free, online email validator and would love to share it with you.

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on.

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say.
