24 alternatives to 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 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… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    In 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.

    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…

    Hi HN, TL;DR Memex is a cross-platform desktop app for vibe coding. Think ChatGPT + Claude Code rolled into one. Why we built it: We love chat tools like Perplexity and ChatGPT. We also love coding agents, like in Cursor and Windsurf. We don’t like that web-based app builders are opinionated about tech stack and we can’t run them locally. So, we built Memex to be a chat tool + coding agent that supports any tech stack. What it can do today: Claude Code-like coding. Agentic web search / research. Pre-built templates (e.g. fullstack, iOS, python + modal, etc). Inline data analysis + viz.…

    I built *Tempmail3*—a lightweight, disposable email service that works instantly and requires *no signup or verification*. *Why I built this* I often needed quick email addresses for testing or sign-ups—but existing services were slow, cluttered, or required entering my real email. So I built Tempmail3 to be as fast and frictionless as possible. *What it does* - Generate a temporary email with one click. - View incoming emails in real time via the browser. - Discard or regenerate the address anytime. - (Optional) This is an open-source project: [GitHub link]. *Technical details & challenges*…

    I wanted to share a project I have been working on over the past week. It is a simple local memory system that saves your sessions into Markdown files, which can be viewed later. I developed this after using Claude Mem. I really enjoyed working with it, but it was consuming a lot of RAM, and each Claude session was becoming a major resource hog. I also tried other plugins and MCP solutions, but ran into similar issues, either slow performance or concerns about data being sent elsewhere. Because privacy was a big thing for me, I decided to build my own solution that keeps all data local.

    Hi HN! I use temporary email services daily, for different purposes such as: - Protect my real email inbox from spam, phishing... - Testing my apps where I need many distinct email addresses I always thought we deserve a better service; most of the popular ones are pretty slow and very ugly. That's why I developed my own. Temp Mail is the fastest and the most modern looking disposable mail generator app on the whole App Store. Available for iOS and MacOS, and Android version coming soon! If you want direct link to App Store, here it is:…

    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…

    TemporaryMail.com was created after struggling to find a working, secure and reliable service which provides temporary email addresses. The goal is to keep this service as simple to use as possible - while also always providing a free option which does not require registration. Some of the features: - Multiple domains to choose from, each with unique hostnames and IPs. - Support for inline images in emails. - Attachments are supported and can be downloaded. - Read your emails safely inside a sandbox (all external scripts disabled). - Read emails without automatically loading any external…
