Ask HN: What cool stuff have you all been using Fable 5 for?

I'm building a meta-framework for LangGraph similar to eve and flue that uses file-based routing, tools, etc. Building developer tooling using agents in the past with codex and opus has been limited, especially with regards to strong typing and DX. Fable 5 is changing this for me.

Built my product fully with that and created the landing page and all marketing stuffs

Changing colour styles.

Per some definition of cool, analyzing newly required price disclosures from health insurance and hospitals in the United States.

A distributing system (AI CMO) that distributes my other products

Building a small webapp to live on my home server to manage my history/science/philosophy/general knowledge podcasts. And then have it connect to sonos to create my own talk radio. Scheduling to auto-play whenever I want, usually 8am M-F. Play a news podcast first thing in the morning, then defer to others.

Paired with that, a MacOS app that detects when I'm on a zoom or google meet call to auto-pause the sonos, then unpause when the call ends.

An inhouse video & image editor (imagine canva QOL goodies & premiere timeline) with remotion for my physical D2C brand. Streamlined to produce rapidly premium/luxury aesthetics creatives for social media and ads

Fixing the GC of my Linux port of cormanlisp

Testing my "executive coaching" system. Fable is more proactive than 4.8. It does things I did not ask, has more opinions. And read a separate Obsidian vault because it thought I want it to. That was odd.

Using it for planning implementations and thinking through edge cases before writing code. It was decent. only issue was that token usage seemed to grow pretty quickly

I've been able to build an experimental version of Live, typed queries on real Postgres.

It started from a question I had: can a Java-shop get the "subscribe, and the UI updates when the data changes" experience of Firebase or InstantDB without giving up a real relational database and without using ORM.

I used Fable 5 to building Odyssa — a 3D travel globe where you can mark every country you’ve visited (or dream of visiting). Turn your travels into a personal memory vault by saving photos and videos to each destination.

used it for planning and architecture level stuff. worked well but the tokens were consumed pretty fast
