Code Recipes vs App Designer

A reference for everyday tasks: Python, JavaScript, TypeScript, Java, Kotlin, Swift, Objective-C, C#, C++, Golang, Rust, PHP, Ruby, Clojure, Delphi and SQL. • Over 5,500 tested examples in 900 sections: strings, collections, files, networking, concurrency, regular expressions, design patterns. • Run in the app: the code executes and the result appears under it. Works for nine examples out of ten. Needs an internet connection. • Edit examples and add your own; they stay in the app and are always at hand. • SQL in its own section: 201 queries against a practice database. • Search looks inside the code itself, not just the titles: remember a fragment and you will find the example. • Everything except running works offline. No account needed. • A section on what changed between language versions: 891 changes across 151 versions, old and new code side by side. • Keyword and function reference: over 3,200 articles you can browse and search like the examples. WHAT THE FREE VERSION INCLUDES About half the sections; 12 runs and 12 edits per day. The keyword reference is fully open, with no counter. The full version unlocks every example, lifts the daily limits and raises the run limit to 80 a day. One purchase, no subscription. Built by a developer for developers. In active development since 2015.
