I’m Bryan, and I make software.
Lately that’s mostly Viauna, an open-source webmail. There are also essays that work through Singapore’s public data, a daily interest-rate tracker, and a few things for my family and my faith.
Viauna
Webmail for the mail server you already have. Conversations, instant search, labels and filters, with contacts and calendars built in. One container to run, and open source under the AGPL.
It’s also the webmail for every mailbox I host.
