I’ve spent nearly seven years documenting how we built Fathom: outages, DDoS attacks, migrations, $100k AWS savings, my cofounder’s retirement, and a divorce. I write transparently because I want other people to learn from my mistakes. These 18 posts tell the story:

Anthropic gave 2 Fable resets yesterday and they don't expire until March 2027. That is wild. I don't want to jinx it but Anthropic are now winning back all of the goodwill they previously lost from Opus 5 and other things.

The reason this looks so polished and not like AI slop is because this guy is an experienced builder and invested well over $30,000 of his time to release this for free. Very cool.

Want your own Slack for $0? I open-sourced Ember. It deploys to @Cloudflare’s free tier in about a minute, works with Slack-compatible payloads, and includes an AI assistant and media attachments.
