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.
