Hey! I guess I'll get some conversation started, this interests me too and I've been doing the same the last few years. I added a page to my site [0] to keep updated with all the tech I use so I'll do some copy-pasting of some standouts. Note that I use Linux and Android, no Apple products here.

- EndeavourOS - easy to install arch-based linux distro

- KDE - desktop environment

- Framework 13 - repairable laptop

- Pixel 9 Pro Fold - my fancy phone cause I like reading books with pictures

- Firefox - web browser (but shoutout to zen browser)

- Kagi - search engine

- BitWarden - password manager

- Dark Reader - dark mode for any site

- Indie Wiki - redirects to non-fandom wikis (cause fandom is cancer)

- AppFlowy - workspace tool (eg. open source notion)

- Notesnook - encrypted note-taking app

- GitLab - open source code hosting platform

- SourceGit - my git gui of choice - Godot - game engine

- Zed - rust-based code editor

- Claude Code - anthropic's ai coding assistant

- REAPER - daw of choice

- OBS Studio - streaming and recording

- Astro - the static site generator that built my site

- Cloudflare Pages - site hosting

- Ghost - used when a family or friend needs a simple site or blog

I tried to use Thunderbird as my email client but I kept defaulting to webmail, but that seems like a good option as you're looking for an email client.
