Your agent just made a ton of CSS changes and you’re trying to make sense of them?
Same here. I was curious if Tidewave could help me understand it all visually.
Here’s how it went. SO COOL!

I've always loved computer art like Boids and now we can do it in Elixir!

I even made a little video explaining some of it, (forgive my rough/rushed editing).

I made a map of 3.4 million Bluesky users - see if you can find yourself!

I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

Sharing just cuz I used Claude Opus to make something similar last week for a client. I knew the data model, and I am well versed in Elixir and Ash. Within 8 hours I had a shippable full featured and tested product. Claude was amazing for Ash Policies. Tidewave.ai also made the speed possible.

This person made a production management tool for his spouse's bakery in #ElixirLang + Ash + LiveView. It's super valuable to have an codebase like this be open source for people trying to get into that tech stack. 💜

Explaining a product in a new category is hard.
Every copy change is a chance to understand it better.
Today’s Tidewave website update feels like one more step forward.
Let me know what you think.

Negative churn is one of those SaaS metrics you read about for years and quietly hope to see one day.
This month, it happened. 🙂
December was our first month with net negative churn.
Five months in, 700+ paying customers, and things are getting better month by month.
Let’s keep going.

I listen to instrumental jazz all day while working. After months, Spotify thought that's all I listen to, but it's only my work music.
So I built (with Claude Code) a tiny macOS tool to keep Spotify Private Session always on.

Just tried asking Claude (desktop) to create a simple Livebook tool for me, and it worked!
Once done, I can click "Open in Livebook" and it opens directly in my Livebook desktop 🎉
