Salam is a general-purpose systems language with one unusual property: every keyword, type, standard library package and error message has both an English and a Persian name, and the two are the same language. Write a program either way and it compiles to the same fast native executable for Linux, macOS, Windows and the web.
import encoding.json
func main:
println "In the name of God"
repeat 3:
println "Hello"
end
names := ["Ali", "Reza", "Fatemeh", "Erfan"]
each name in names:
println name
end
println json.Marshal(names)
endSalam aims at the performance of a systems language with the readability of a teaching one.
Keywords, types, the standard library and every diagnostic exist in English and Persian. This is not a skin over an English language: both spellings go through the same lexer, and salam translate converts a program from one to the other.
Salam compiles through LLVM or C to a native executable. No virtual machine and no garbage collector; the binary is small and runs straight on the operating system.
Types are checked before the program runs, and the compiler rejects the usual quiet mistakes: an unused variable or function, a declaration used before it is defined, an assignment to something declared constant.
Salam has a built-in layout language that emits HTML, CSS and JavaScript, and the compiler also targets the browser and WebAssembly.
More than 150 packages ship with the compiler: strings and files, JSON, HTTP and TLS, cryptography, databases, images, tensors and machine learning.
Formatter, documentation generator, English and Persian translator, debugger, REPL, online editor and plugins for eleven editors, all behind the single salam command.
On 39 identical programs Salam averaged 10.6 ms, C 11.7 ms and Rust 11.3 ms.
Speed is not only a benchmark story. Salam already runs real software.
Services built with Salam comfortably serve more than 150,000 users, and do it on a single small server.
An operating system has been written entirely in Salam, so the language is ready for the lowest layers of a software stack.
The compiler is written in Salam and nothing else: more than 200 Salam source files that compile Salam.
The program that builds this site, the benchmark harness behind this page and the Salam code formatter are all written in Salam.
Both of these are the same program. They produce the same output and compile to the same executable.

Installing takes under a minute and needs nothing else on the machine.
Run this in a Linux or macOS terminal. The Windows command is on the install page.
{ curl -fsSL https://raw.githubusercontent.com/SalamLang/Salam/refs/heads/main/install.sh || wget -qO- https://raw.githubusercontent.com/SalamLang/Salam/refs/heads/main/install.sh; } | sh
Create a file with a salam extension and write your first program.
echo 'func main: println "Hello, world!" end' > hello.salam
Compile and run it with one command.
salam run hello.salam
Salam is built and tested across operating systems and architectures.
Ask questions, get working code and let it build your project on your own computer.
A chat assistant built for Salam. It answers from the real language and standard library and checks the code it writes with the compiler.
A desktop app for Windows, macOS and Linux. Salam AI runs commands, edits files and runs your tests in a folder you choose, within the access level you set.
Salam is a general-purpose, statically typed, open source programming language. Its distinguishing feature is that it is fully bilingual: you can write a program in English or in Persian, and either way it compiles to a native executable for Linux, macOS, Windows and the web.
Every keyword, built-in type, standard library package and compiler message has an English name and a Persian one, and the compiler accepts both. Persian digits are accepted wherever English ones are. The command salam translate en program.salam converts a Persian program to English, and translate fa goes the other way.
Yes. Salam compiles to native machine code with no virtual machine and no garbage collector. Across our benchmark of 42 equivalent programs it ran on a par with C and Rust and many times faster than Python and PHP. The speed page has the numbers and the method.
The same things any systems language is good for: command line tools, servers, compilers, numeric work, embedded and operating system code. The compiler itself is written in Salam, and so is an operating system and the program that builds this website.
Yes. Salam is released under the GNU GPL version 3 and the full source is on GitHub.
Salam installs on Linux, macOS and Windows, and compiles programs for those plus WebAssembly and the browser. You can also write and run code in the online editor without installing anything.
No. The English form of the language is complete on its own: this site, the course and the standard library reference are all usable without a word of Persian. The Persian form is there for people who prefer it, and the two interoperate.
The Salam editor runs the whole compiler in your browser. Nothing to install: write code and see the result.
