24 alternatives to Cassette, a Personal Programming Language

I made this simple language over the past year, and it's time for me to say it's "done" (for now) and focus on other projects. I've struggled to answer the question "what is this language for?" other than "it's just for me" — and that's probably good enough. But I also wanted to make something "complete" that others could use if they wanted to. Writing my own language was an incredibly rewarding experience, and I'd recommend everyone trying it. Let me know if you have any questions or feedback, and please share your own experience if you've also made a language.

Cassette is a simple programming language created as a personal project over the past year. Designed primarily for its maker's own use, it is now available as a complete implementation for others who want to explore… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Cassette, a Personal Programming Language launched in 2023; newer entries below may have overtaken it.

    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 :)

    The book page links to a blog post that explains how I got about it (and has a link to sample content), but the TL&DR is that I could not find a lot of books that were on "our" history _and_ were larded with technical details. So I set about writing one, and some five years later I'm happy to share the result. I think it's one of the few "computer history" books that has tons of code, but correct me if I'm wrong (I wrote this both to tell a story and to learn :-)). My favorite languages are Smalltalk and Lisp, but as an Emacs user, I've been using the latter for much longer and for my…

    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

    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…

    Hey! I’m JC. I’m 17 and part of Hack Club, a nonprofit where we help teenagers ship programming projects with their friends while growing technically. A while ago, I asked myself the question, “How exactly do programming languages work behind the scenes?” It seemed really daunting until I went to a half hour workshop at a high school hackathon about writing a tree-walk interpreter and realized that getting started was actually super fun. This guide is designed in the vein of that - to get people, especially teenagers, started on learning how to build a programming language in a literal…

    I've been working on this small, slightly weird expression-oriented programming language for a little while now and feel ready to share it with others. I use it pretty often now in my day-to-day and work life, as a scratchpad for doing a bit of quick math or picking some pieces of data out of a JSON payload. Would really appreciate any feedback about the syntax, docs, features that are glaringly missing, etc. Before anybody mentions it: I know the performance is pretty lousy when dealing with a lot of data. If you can believe it, the runtime is about 100x faster than it used to be! Long term…

    Hi! I am doing a learning project, attempting to build an imperative language (and interpreter). The end product will be useless for others, I just want to learn and better understand how to build imperative languages. :) If someone else shares this interest and want to give some good hints on good resources I would be grateful. Currently I am looking at an awesome text by Bob Nystrom. All suggestions and tips on resources are most welcome. I am very much a beginner in this, but I find this topic very fascinating. Mail me or post links here! Cheers! You can try a beta version Online at…

    AntiLang is an interpreted programming language written in Go. The basic idea of this is to keep all the logical parts of a language same, but reverse the structure of it. The idea for this project came when I was having a long midnight conversation with my friend and thought of writing such a weird language. The initial draft was far worse than the current implementation; we thought of reversing the brackets and the language would be read from bottom to top. I'm happy that I dropped that idea Technical details: As the interpreter is written in Golang, I compiled it to WASM, and the whole…

    This is a hobby project of mine that I started a few years ago to learn about programming language implementation. It was created 95% without AI, although a few recent commits include code from Gemini CLI. I started out following Crafting Interpreters, but gradually branched off that until I had almost nothing left in common. Tech stack: Rust, Cranelift (JIT compilation), LALRPOP (parser). Original title: "A small programming language where everything is a value" (edited based on comments)

    Here is a tool I built initially for myself to help with my German and Greek language studies. It started as a hack for creating Anki cards from native language audio. It extracts the words, finds their base forms (lemmas) and groups the examples by the lemma. At some point I realised that I have a transcription with word level timestamps that opens a lot of other opportunities. So I added a mode to click the first and last word in the transcript and it starts looping with the right gap and repeat count. Another feature I use a lot is selecting an audio fragment, sending a predefined prompt…

    Ever since I got my first computer, a TI-99/4A, at age 13, I've been fascinated by programming languages. I've written a few interpreters, but this is the first time I've come back to the first language I've ever learned, BASIC. I started ClifferBasic as a way to shake out bugs and find feature weaknesses in another project I'm working on, Cliffer, which is a library for writing CLI applications in .NET using attributed program, but it's taken on a life of its own and has become a rather fun project. I'm planning to flesh out the BASIC implementation over the coming weeks, but I'd like…

    Hi all! I built FlipJump, a programming language with just 1 opcode, yet capable of any computation. It started with thinking of the idea of the minimalistic language, but it's more than that - I had to set up the whole environment for it: I have written a macro-assembler, an interpreter for the binary, and a very extensive standard library. I also written about ~30 programs in it. Also, the standard library is tested. I also wrote an esolangs page: https://esolangs.org/wiki/FlipJump Tell me what you think!

    This is the first project I haven't written a single line of code. The entire codebase was prompt generated in Cursor using mostly Claude Sonnet 4.5. It's also the first time I'm genuinely happy with the end result from AI coding. What do you think?
