Flycatcher is a general purpose, high-level, multi-paradigm, statically typed, compiled programming language. The goals of Flycatcher are similar to that of Rust; create a safe, fast programming language that can offer the efficiency and ability of systems programming to programmers new and old.

Flycatcher is not in a released alpha state yet, meaning it is not yet functional. While some features may be finished, others may not be, such as the compiler's code generator.


  • Efficiently prevent the need to manually manage memory. In the C language, explicit calls to malloc, realloc and free are very common, often necessary for even small programs. The management of memory should happen at compile time, for maximum performance.
  • It should be easy to learn, for programmers new and old.


Hello, world!

@func main() {
    println("Hello, world!"); // => Hello, world!

Duck Typing

Flycatcher is a statically "duck typed" programming language, which means "if it looks like a duck and quacks like a duck, it must be a duck." It stems off of this concept quite a bit, for example:

@type my_type = {
    value: uint64 // Unsigned 64-bit integer

@func example_function(obj: my_type) {

@func main() {
        value: 42
    }); // => 42
