PolyCode Programming Languages

Compare 38 coding languages

$2.99 · Designed for iPad. Not verified for macOS.

See how loops, pattern matching, error handling and 40+ more features look across 38 programming languages — side by side, fully offline. New: guess-the-language quiz. PolyCode is a side-by-side reference for programmers who work in — or are curious about — more than one language. Pick a feature like loops, pattern matching, generics, async/await or error handling, and instantly see the idiomatic snippet for each of 38 languages, with a short note on what makes each one distinctive. Choose exactly which languages you want to compare and ignore the rest. It's the answer to "how do I do THIS, but in THAT language?" — without ten browser tabs. Everything ships inside the app: no account, no network, no tracking. 38 LANGUAGES BASIC, C, C++, C#, Clojure, Crystal, D, Dart, Elixir, Erlang, F#, Factor, Fortran, Go, Groovy, Hack, Haskell, Hy, Io, Java, JavaScript, Julia, Kotlin, Lua, Mercury, Nim, OCaml, Perl, PHP, Python, R, Raku, Ruby, Rust, Scala, Swift, TypeScript, Zig. 43 FEATURES, IN 10 CATEGORIES Basics, Strings, Control Flow, Functions, Data Structures, Types & OOP, Functional, Robustness, Concurrency, and Modules & I/O — from "Hello World" and string interpolation to pattern matching, generics, operator overloading, channels, currying and JSON. FOUR WAYS TO EXPLORE • Features — pick a feature, compare it across the languages you care about. • Languages — browse every language (sorted A–Z, by decade, or by typing discipline) and open a profile with all of its snippets in one place. • Search — full-text search inside the actual code and notes: find every "async", "match" or "|>". • Quiz — guess the language from a random snippet and build a streak. BUILT RIGHT • 1,598 hand-written, idiomatic snippets — and honest blanks where a language genuinely lacks a feature, instead of fabricated code. • A custom syntax highlighter that even covers niche languages no off-the-shelf highlighter supports (Factor, Mercury, Hy, Io, Raku). • Follows your system Light/Dark appearance. • 100% offline. No sign-in. No analytics. No ads. Whether you're learning a new language, switching between projects, prepping for an interview, or just settling an argument about which language has the nicest match expression — PolyCode puts the comparison one tap away. • Compare 43 language features across 38 languages, side by side. • Browse languages by name, decade or typing; search inside the code; quiz yourself. • Fully offline, no account, follows Light/Dark.
