24 alternatives to Bolt – A super-fast, statically-typed scripting language written in C

I've built many interpreters over the years, and Bolt represents my attempt at building the scripting language I always wanted. This is the first public release, 0.1.0! I've felt like most embedded languages have been moving towards safety and typing over years, with things like Python type hints, the explosive popularity of typescript, and even typing in Luau, which powers one of the largest scripted evironments in the world. Bolt attempts to harness this directly in the lagnauge rather than as a preprocessing step, and reap benefits in terms of both safety and performance. I intend to be…

Bolt is a statically-typed scripting language written in C designed for embedding in applications. It combines static typing directly into the language rather than as an add-on, aiming to provide both safety and… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

ScrapScript – A tiny functional language for sharable software▲503
Hi friends, I started casually working on scrapscript in 2015. I built a few compilers over the years to test out various ideas/implementations, and I think I'm finally happy with the overall design. The code is not public yet. Email me at [email protected] if you're interested in joining the core team later this year. Let me know if you have any questions or feedback :)

Fuse – statically typed functional programming language▲121
Hi HN! I've been working on the fuse programming language, it's a statically typed purely functional language with higher-kinder types and ad-hoc polymorphism. It compiles to the GRIN whole-program optimizer, producing LLVM-generated native code. Fuse supports ADTs, Generics, Type Methods, Traits, Pattern matching etc. all in a functional style with no mutations. I’ve been developing the language for 5 years, with code written in Scala. I’ve started coding the language from the base of System F that was implemented as part of the book: Types and Programming Languages (tapl). And then…

Aberdeen – An elegant approach to reactive UIs▲224
Yes, another reactive UI framework for JavaScript. Bear with me, please... :-) I 'invented' the concept for this back in 2011, and it was used (as a proprietary lib) in various startups. Even though many similar open source libs have been released since, and boy have I tried a lot of them, none have been able to capture the elegance and DX of what we had back then. I might be biased though. :-) So I started creating a cleaned-up, modern, TypeScript, open source implementation for the concept about five years ago. After many iterations, working on the project on and off, I'm finally happy…

I made an esoteric programming language that's read like a spellbook▲176
i made an esoteric programming language which i call spellscript. every program is a "spell" written in a "grimoire," and you have to use keywords like summon, enchant, inscribe, and conjure. it's literally read like a spellbook because the syntax consists of all natural language, and newlines are optional. your code can now be an essay, like everybody wants! for example, if you want to print something, you'd write: `begin the grimoire. inscribe whispers of "hello, world!". close the grimoire.` it has variables, dynamic typing, arrays, functions, conditionals, loops, string manipulation,…

I'm making a dynamic language in Rust▲184
An implementation of a dynamic programming language in Rust. Includes: Parser/Compiler, REPL, Virtual Machine, Bytecode Disassembler This started out as a learning project to teach myself Rust. It has grown into a decently substantial piece of software and I've learned quite a bit in the process! Some neat things: + A garbage collector that can store dynamically sized types without any double-indirection (i.e. I have my own Box implementation with manual alloc/dealloc) + The smart pointer used to reference GCed data is a thin pointer. The ptr metadata needed for DSTs is stored in…

The Aria Programming Language▲48
Aria is a modern, dynamic scripting language. It is meant to be a "sweet spot" language, easy to pick-up and enjoyable to use. It comes with a familiar C-style syntax, and draws inspiration from a variety of languages. It has a small but usable standard library and strives to be a low-ceremony-get-stuff-done kind of language. It is currently at version 0.9 and I would love feedback as I work towards getting it to 1.0.

Going into freshman year, figured I should build an interpreter▲138
Hi all! I'm going into my freshman year, and figured that the best way to prepare for the intro to programming Racket course would be to implement my own garbage-collected, dynamically typed, functional programming language in C ;) Anyways... here's the repo: https://github.com/liam-ilan/crumb I started learning C over the summer, so I still have a whole lot to learn... Any feedback would be greatly appreciated! :D

Crust – A CLI framework for TypeScript and Bun▲95
We've been building Crust (https://crustjs.com/), a TypeScript-first, Bun-native CLI framework with zero dependencies. It's been powering our core product internally for a while, and we're now open-sourcing it. The problem we kept running into: existing CLI frameworks in the JS ecosystem are either minimal arg parsers where you wire everything yourself, or heavyweight frameworks with large dependency trees and Node-era assumptions. We wanted something in between. What Crust does differently: - Full type inference from definitions — args and flags are inferred automatically. No…

I built a minimal Forth-like stack interpreter library in C▲47
This weekend I created stacklib.h - a single-header library that brings Forth-style stack operations to C. It implements a basic interpreter with: - Stack operations (push/pop/dup/swap/over/drop) - Arithmetic (+, -, *, /) - Output (., emit, cr) - Stack inspection (.s, depth) Example usage: Stack s; stack_init(&s); dict_init(); exec(&s, "10 20 + ."); // Prints "30" exec(&s, "1 2 3 4 .s"); // Shows stack contents The library is self-contained, requires no dependencies, and handles basic error checking. It was inspired by wanting to understand…
