Make database software, simply.

Real CRUD apps, zero to prod in a month real-time.

0m57s Make database software in real-time
Hyperfiddle takes the messy, complicated world of database programming and web development, and flattens it into a real-time editor.
The interactive editor has three facets:

1. Database query and form

0m14s Query and form interactive editor, note the undo/redo
All your fiddles have a Datomic query. Datomic is a new kind of database designed for 2020-era business applications, competitive in use cases with SQL and GraphQL. Datomic is the key ingredient that makes Hyperfiddle possible.
From your Datomic query, Hyperfiddle generates
  • complete working API
  • user interface and forms
  • cloud backend and database

2. View – Markdown or ClojureScript

0m26s Pictured here is the markdown editor, which is for getting things done fast. ClojureScript editor not pictured.
Out of the box UI scaffolding:
  • Automatic typed widgets
  • Recursive tables and forms
  • Automatic CSS classes
  • Router
  • Reasonable defaults for everything a real app needs
We say “UI scaffolding” because the automatic UI is just a jumping-off point. Add some flavor — only when you need to — with a dash of ClojureScript, or throw the whole thing away and bring your own frontend.
Fiddles have links to other fiddles, a graph. Select lists are embedded fiddles.
This lets you weave individual fiddles into larger hyperfiddles.
They work like HTML:
  • Anchors navigate between fiddles
  • Buttons submit transactions
  • Iframes embed one fiddle inside another
Links have a small number of properties which combine to describe an arbitrary database transaction. Every-day transactions like parent-child references are automatic. Sophisticated business transactions can be coded in Clojure.

Automatic backend and web-service

Datomic Cloud manages AWS, and Hyperfiddle manages Datomic.
Designed for Datomic Cloud: serverless enterprise database tech for the 2020s.
Hyperfiddle's backend is smart. It uses the fiddle-graph to optimize data loading behind the scenes, like how Chrome optimizes web page loading. Today the optimizer is simple, but over time your apps will get faster — without you doing any work!

Users and security (experimental)

Security here is read anything, edit what you own
Fiddles are real multi-user applications, suitable for the open internet as well as internal tools.
  • Authentication, users, profiles
  • Built-in auditing
  • Opt-in security models for permissions and access control
  • Bring your own security with hyperfiddle.jar

Try it now!

Datomic user already? hyperfiddle.jar is for you

Slot hyperfiddle.jar into your existing Datomic infrastructure and start making internal tools today. (Coming Soon)
hyperfiddle.jar is a CLJC library that supports many I/O configurations, depending what you want to do:
  • JVM/Pedestal
  • Node/Express.js
  • web browser
Coming soon:
  • Datomic Cloud and Ions
  • Roll your own

Business model and pricing

hyperfiddle.jar, which includes the server and everything you need to self-host your apps, is free and open source (pending cleanup asap).
Hyperfiddle Editor needs a license for on-prem use. This business model will let us make Hyperfiddle IDE as mature as Excel. We are happy to provide access to the editor's "source" to licensees, it is actually a database containing EDN, Reagent views and CSS.
The Editor is of course optional; developers are welcome to git clone hyperfiddle && lein new --whatever and code your fiddles into .cljs and .edn files, which is common in mature projects like Hyperfiddle itself.
Coming soon.

Developer FAQ

Hyperfiddle can do anything Rails can do. Enterprise app with sophisticated backend integrations? No problem: Hyperfiddle is a jar file. Fork it and integrate it with your JVM codebase.
Invisible data sync. Hyperfiddle loads just the right data, automatically. Your app specification captures your API inter-dependencies as a graph, so data sync reduces to a graph partitioning problem. Hyperfiddle optimizes your service dynamically in ways hand-coded backends cannot.
Immutability and functional programming. Hyperfiddle is made possible by unique capabilities of Clojure/Script and Datomic, including immutability in the database and code-sharing across platforms.
Server rendering and static sites? Yes, all hyperfiddles are progressive web apps. Even API responses are served Cache-Control: Immutable – check the network tab as you navigate our docs!
SQL? No, not without an adapter, an immutable database is necessary. For example, interactive undo/redo — of database transactions! — falls out of immutability for free.
Foreign REST APIs? Yes, and this is important to us. Today this is experimental and undocumented, there is more work to be done here.
GraphQL? Eventually, this is a great fit.
Javascript, React.js, JSX? Eventually, this is important to us. Today, the out-of-box forms library uses ClojureScript's Reagent, which is backwards compatible with React.js.
Re-frame, Hoplon, Rum, etc? We have no hard dependency on Reagent, other than the out-of-box forms library. Note that Re-frame doesn't support server side rendering.
Proper frontend dev workflows? Eventually, this is important to us.
External scripts? Yes (experimental).
React Native? Not anytime soon.
