Mephisto – A RAM-only, ad-free disposable email PWA built with React
Hi HN, I built Mephisto because I was frustrated with the current state of disposable email services—most are riddled with intrusive ads, trackers, and captchas. I wanted a tool that felt like a proper developer utility rather than a spam farm. The stack is React, Vite, and Tailwind. Key architectural decisions: 1. Volatile Memory: The backend writes nothing to disk. Once a session terminates, the data is irretrievable. 2. Client-Side Entropy: The password generator runs locally in the browser; keys are never sent to the server. 3. PWA: It's installable and designed for low latency using…
Mephisto – A RAM-only, ad-free disposable email PWA built with React launched on December 17, 2025 with 21 votes, #573 of 11,628 launches that month and more than 90% of that year's launches.
In plain words
Mephisto is a disposable email service built as a progressive web app for developers who want a cleaner alternative to ad-heavy competitors. It stores data only in RAM—everything disappears when the session ends—and generates passwords locally in the browser without sending keys to servers. The tool features WebSocket-based mail delivery for low latency, an installable PWA interface, and the ability to transfer active sessions to mobile via encrypted QR code. It's free and open for public use.

Burner NoteJan 2026 · burnernote.com · ▲222In 2021 after getting thoroughly sick of Privnote, i built "Burner Note". Even though i didn't promote it in anyway other than a post here and a post on reddit, it ended up getting about 7000(ish) unique users per month. I kinda let it die about 18 months ago but i've resurrected it with some big upgrades. Most botable the app is now truly end to end encrypted (previously was just server side), and I've added dark mode as well as a few other bells and whistles. Feedback welcomed.
- AAAn ad free temporary mail service2024 · ▲54
Made this privacy conscious temporary mail extension as a hobby a few years ago as I found a cool domain. I've now revamped the UI, added more domains and created an extension that shows your inbox in your browser (it only asks for permission to read from TemporaryMail.com and not all sites like the other extensions), it's also free from ads (paying the service out of pocket and perhaps adding an upgrade feature later on). What makes this site a bit more unique is that I wrote the email parser from scratch following the RFC (took me 2 months and tons of testing) so it should display all…

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. 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…
