acley··on A Discord Alternative – Echoed
Yeah, the RAM numbers are off, those are from different builds, and we never synced them. my bad, fixing today. And it's two of us and the landing page got like a day of attention because everything else felt more urgent. not really a defense, just what happened. Same reason it's nowhere near as rich as Discord's site.

"free forever" — it's already been free 1.5 years, we were Zorium before the rebrand. If we do add a paid plan later the stuff that's free now stays free, new stuff gets charged for. we also build business software, so we've got spare server capacity, runs fine on it.

Thanks for the feedback tho :)

yeah 30 N Gould is a registered agent. We registered a US entity mainly for stripe + dmca since users upload stuff which content tons of restriced contents. it was the cheapest way to do it without a US office.

We have been online for more than 1.5 years. Back when we started, we didn't see Discord alternatives popping up left and right, so we created our own. Nowadays, there are like 10 of them popping up every single day, most of those are below par and completely usable. If you like to try out a new one you can give us a try no stress haha bye

Hey everyone, we've added GitHub integration. You can now use your own IDE, code locally, and push to a public GitHub repo we'll grade it and give you a score for each lesson. We've also added free certification: when you complete a course, you'll receive a free certificate that anyone can verify.

I've implemented it

Every course now has a "work in your own editor" mode: you can download a zip with the starter code for every lesson plus a run_tests.sh that runs the full test suite locally. After that, you can push it to a public GitHub repo, we will judge it based on our grading system and internal tests

You were right, and this comment stuck with me so I have decided to go ahead and implement it.

I am looking for sponsors and have already spoken with a few companies.

I think you didn't go through a few courses. Many of those are actually better than whatever you can get from other places

PAID with fewer courses.

Vibe coded AI Slop? Feel free to contribute (even with the help of ai). If something closer to it exits I wouldnt have made it

jig is not supported by judge0 (our code execution library)

How can you be the PRODUCT when we have only 500 users? WE are NO GOOGLE my friend. BTW you can use guest mode if feel like you dont want to singup

I respect your opinion too.

But can you run it on their platform? NO, you need to run it on your own machine which takes a bit of work. And we have over 80 courses waaay over whatever codecrafters has

bots are hitting tons of endpoints bro. You can keep using the platform as guest

Unfortunately, I dont think you can run the tests on your own machine.Tests run on jude0, which takes about 20 GB of RAM to run

I've also trained over 100 students in Python back in 2021, when Python was often looked down upon in academia for not being a low-level language. My belief has always been that if someone learns one programming language properly, they can pick up another in no time.I've seen beginners spend months going through 300-video YouTube playlists just to learn JavaScript. People don't need 300 videos to learn a programming language they just need to understand the fundamentals and build projects.

This project, however, is aimed at people who already know a programming language but want to understand what goes on behind the scenes of popular software: how it's designed, why certain architectural decisions are made, and what things to avoid.

1. We have temporarily removed it due to abuse (people are sending their own project code through it). 2. Tests are run on our dedicated server. I had some spare servers that we bought for our other platform echoed. gg 3. Will you accept contributions to the teaching material? ofc we would. I am also thinking of open-sourcing the project 4. What is the AI policy for contributors? You can use AI(we also used it), but the quality of the course, should match the rest of the courses

its free

I kept noticing that most "learn to code" content is tutorials you copy-paste, so I never had to actually understand why anything worked. I built this to flip that: each lesson gives you a real spec (e.g. implement the Redis SET/GET protocol) and you write the code yourself, then it actually runs against tests. Right now there are 80+ of these "build X from scratch" courses — Redis, a database, Git, a compiler, a container runtime, a raft KV store, etc. — across Python, Go, Rust, C, C++, and others. Would love feedback, especially on where the early lessons feel too hand-holdy or too sparse.
