What it does
EmailSweeper validates unlimited emails without limits. Built because competitors charge $500/month for something you can do locally. This tool runs on your computer, checks email format + domain configuration (MX records, SPF, DMARC, DKIM), and scores overall email quality. Unlike cloud-based validators: • No monthly limits • No API keys • One-time $49.99 (forever) • Runs offline after activation • Your data stays private Perfect for cold outreach, lead gen, or CRM cleanup.

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.

How it works: Paste an email > click Validate > get a clear result with…

Talanoa▲346Hi 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.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped!
