Looking for feedback and suggestions!
This is an open-source email client designed for Gmail that aims to replicate Superhuman's performance and keyboard-driven workflow. Built by developers for developers, it currently emphasizes vim-like efficiency and… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Zero▲845Hi HN, I’m Nizar, and I’m building Zero (https://0.email) — an AI-powered email client that manages your inbox for you. Email hasn’t changed in decades, even though the way we work has. The average knowledge worker now spends close to 30% of their week on email, constantly reacting, replying, and sorting through noise. It’s become one of the biggest productivity sinks in modern work. At the same time, AI has transformed how we write, plan, and collaborate — yet our inboxes are still stuck in the past. I built Zero to fix that. Zero automatically prioritizes, organizes, and even…

I've been frustrated one too many times by terrible airplane wifi and not being able to load Gmail or Superhuman when all I want to do is get a few simple text-only emails out the door. These clients have become pretty bloated with the assumption you've always got great bandwidth. So I vibe coded BAREMAIL. It's open source, has no backend, and you can just set it up for yourself. Takes ~3 mins to setup API access via Google Cloud Platform (thanks for making this not super easy Google!) I tried to maintain nice design and some important keyboard shortcuts without getting to overBEARing.
