Roc Has a Free API: The Fast Functional Language Designed for App Developers

Roc is a functional programming language focused on speed, simplicity, and friendliness. It compiles to machine code via LLVM, has no runtime exceptions, and is designed to be the 'fast functional language for app developers' — not academics. Why Roc? Fast — compiles to native code via LLVM No runtime exceptions — everything handled via Result/Tag unions Platform system — separate pure logic from I/O effects Great errors — compiler messages are paragraphs, not cryptic codes Simple — no type classes, no monads, no macros Install # Download (nightly) curl -sSfL https://github.com/roc-lang/roc/releases/latest/download/roc_nightly-linux_x86_64-latest.tar.gz | tar xz # Or build from source git clone https://github.com/roc-lang/roc.git cd roc && cargo build --release Hello World app [main] { pf: platform "https://github.com/roc-lang/basic-cli/releases/download/0.10.0/vNe6s9hWzoTZtFmNkvEICPErI9ptji_ySjicO6CkucY.tar.br" } import pf.Stdout main = Stdout.line! \"Hello from Roc!\" roc run hello.r
