Software & services,

The Hardware

Safari: everything on iOS is technically Safari, so this is a bit of a concession to an operating system restriction. The experience of using Safari is quite nice—the privacy features, extension support, and so forth. -- The developer experience still lags behind other browsers.
Obsidian: fast and configurable (or minimal) as you'd like; I use it for all of my notes and writing. Supports CLI!
Parcel: the most flexible and reliable package tracker for Apple's ecosystem.
Day One: an awesome journal app!
MX Clients: Mailmate, Fmail3, AERC
Messaging: Signal, duh
Tasks: Things III

Magnet: flexible, powerful window management.
Mp3tag: a powerful utility for editing and managing music metadata (it also allows you to edit extended tags, which can be important when adding music to Navidrome).
Permute: a useful utility for quickly converting files to different formats.
noTunes: a lightweight utility that prevents Music.app from launching. It also allows you to set a new default music player.

iTerm2: a feature-rich terminal app more flexible and powerful than the native macOS terminal.

Fastmail: the premier email and calendar provider.
Starlink: Gen3, impressive speeds, reliable AF
AT&T Mobility
Codamail: Old-school Usenet and IRC sysadmin hackers who know how to admin an email server. Affordable & highly recommended.
Kagi: my favorite search engine that avoids AI cruft, provides relevant results and myriad other features (like ranking results) and highlights trackers present for a given result.
Coolify: for web application management and deployment.
Hetzner: a modern, reliable, and dependable VPS.
FreshRSS: not the prettiest RSS reader, but it's powerful, flexible, and reliable.
linkding: a self-hosted bookmark manager for things I want to reference or read later.
Goatcounter: lightweight, privacy-friendly, and performant analytics.
Bäikal: a lightweight CardDAV and CalDAV server I use to sync contacts across devices (as Proton doesn't sync with local contacts). Ente Photos: end-to-end encrypted and open-source photo storage and management.
bunny.net: an affordable and altogether user-friendly CDN & DNS host. I host the images for my site with them and use their optimizer/transforms heavily.
Backblaze: my go-to web storage platform. I use it to host the images for my site, back up my laptop, archive data, and back up Coolify databases.
NextDNS: a privacy-focused, set-it-and-forget-it DNS service. I use their security features on my home network and a profile with strict ad-blocking rules on all of my devices.
