Description
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.
