Like others, it took me a while to understand what this actually does. Even coming from a Clojure+Datomic background.

As best I can tell, this is like phpMyAdmin for Datomic. But the cool and unique thing about Hyperfiddle is that in addition to writing queries and seeing the results, you can customize the result display using markdown or even arbitrary clojurescript code. Then you can generate forms to input new data (based on the schema of the database), connect it to more clojurescript, and before you know it you've built a web app. Because the whole thing is web based, you can send a link to your "fiddle" (web app) to other people, and they can use it without knowing anything about programming. This is all without git, editing text files, or even thinking about deployment or hosting. I think that's all pretty cool.

In most situations, this would be dangerously powerful, especially running on a production database. But Datomic has unique facilities for speculating "what if I transacted this" (which is how the hyperfiddle staging area works). Datomic also has powerful undo and time-travel options, which makes it much less terrifying to hyperfiddle it.

It's also cool that hyperfiddle queries/views/code are all stored in Datomic, so you get a sort of version control type layer built-in.

I think this is a cool vision for making it much quicker to develop lightweight database-backed web apps. Obviously the current state of hyperfiddle needs a lot of work on the UI and home page to explain this all.
