MailFrom.dev – A sandbox SMTP for devs

Hi HN, Two months ago, we launched MailFrom.dev, a fake SMTP server for developers who want to test email sending without hitting real inboxes – think of it like a simpler, cheaper alternative to Mailtrap or Mailhog with a focus on ease of use. Since then: - We’ve had 55 developers sign up with 4 paid subscription active and 821 test emails sent - Improved stability, speed, and small features our early users needed - Worked hard to add roles (wich will be released later next week) What's improved: - Better UI to inspect headers, bodies, and attachments - Faster inbox refresh and sync between…

    This is a side project of mine. Use this as your SMTP server in a test environment to guarantee that your users don't receive test emails. Looking for feedback, especially on the security side.

    Hi all! Excited to share cc.dev after months of work and refinement. The idea for this product came from trying to do email marketing for my side project, CubeDesk, a site where Rubik's Cube enthusiasts can time themselves, race with one another, train algorithms — it's a fun niche! With over 40k users, sending even a single campaign was becoming expensive with MailChimp. I knew AWS SES would be much cheaper, but it’s just an API with none of the other necessities you need for a robust email marketing platform. Beyond cost, I was also frustrated with having to make sure my database was…

  • Talanoa▲346

    Hi 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…

  • Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
