https://www.repth.com , an AI cycling coach that I vibe-coded back when gpt-3.5 was hot and vibe coding wasn't yet a thing. We've come a long way! Free for athletes, but I license the underlying "coach" logic to actual, human coaches.

How does this compare to Trainer Road?

https://unrav.io . Lets users reshape any article, paper, or video into the form that actually helps them think, mind-maps, summaries, podcasts, or interactive Q&A. Launched as part of the Bolt.new hackathon in August and growing steadily. Going from a 100% vibe coded web app to a full production system has been quite a ride!

I’m still selling Computer Engineering for Babies. And I just launched a new book called Simple Machines Made Simple on Kickstarter a month or two ago. Both books are basically just simple interactive demos for kids and adults.

https://canine.sh - makes it dead simple to turn your Kubernetes environment into a Heroku like PaaS.

Mainly used in organizations with developers who want to deploy to a corporate Kubernetes environment, but don’t want to deal with the complexities.

It’s fully open source so we’re covered by sponsors, the largest being Portainer $5k+ / m from sponsorships.

Makes it possible to keep the cloud offering totally free.
