RunMyMailer

What it does

RunMyMailer is a simple local SMTP server that lets developers and businesses send real emails directly from their own computer or server. Unlike traditional email APIs and third-party SMTP services, RunMyMailer gives you a local SMTP environment without requiring a separate email gateway. Connect your existing applications using standard SMTP settings and start sending emails.

RunMyMailer is a free, lightweight Windows app that gives every local app, script, and CMS a real SMTP server on 127.0.0.1. Send actual email from localhost — no cloud gateway, no monthly quotas, donations welcome.

RunMyMailer is a lightweight desktop app that spins up your own SMTP sender on 127.0.0.1 — so every app, script, and CMS on your machine can send mail without touching a third‑party gateway. No monthly quotas, no API keys to rotate, no third party reading your outgoing mail. Point any app at localhost and go. A full SMTP endpoint on 127.0.0.1 that any language or framework can talk to — swap one config line and every existing mail call just works. Unlike a dev-only catcher, RunMyMailer actually relays to real inboxes — using the SMTP credentials you already own. No cloud dashboard, no third party queue. Your message content never leaves your network until it hits the recipient's server.…from runmymailer.com

  OwnTime – a chess clock for your day's priorities▲110

  I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up.
