Sendune – open-source HTML email designer▲429
Demo: https://designer.sendune.com/ Code: https://github.com/SendWithSES/Drag-and-Drop-Email-Designer HTML for email is probably the hardest code to write. Even a teeny-tiny deviation from the rules will break the email in untold combination of os/desktop/mobile clients. It's mid 2024. Almost 50 years since email was invented and 35 years since HTML was born. A 'basic-open-source-HTML-email-designer' must be a solved problem, right? We thought so too. Sadly, that's not the case. There are a few decent open source email designers but they carry…

SMTP Tunnel – A SOCKS5 proxy disguised as email traffic to bypass DPI▲140
A fast SOCKS5 proxy that tunnels your traffic through what looks like normal SMTP email, bypassing Deep Packet Inspection firewalls. How it works: - Client runs a local SOCKS5 proxy (127.0.0.1:1080) - Traffic is sent to server disguised as SMTP (EHLO, STARTTLS, AUTH) - DPI sees legitimate email session, not a VPN/proxy Features: - One-liner install on any Linux VPS - Multi-user with per-user secrets and IP whitelists - Auto-generated client packages (just double-click to run) - Auto-reconnect on connection loss - Works with any app that supports SOCKS5 Tech: Python/asyncio, TLS…

A WordPress plugin that rewrites image URLs for near-zero-cost delivery▲67
Hi HN, I built a WordPress plugin called Bandwidth Saver.
