Congrats on the launch! The "create once, ship everywhere" concept is super compelling. Being able to repurpose content across formats like this is a huge win for software education.
I’ve been building something similar with CodeMic [1] and found that replaying courses *inside* the IDE makes a big difference letting users immediately play with the code instead of just watching a video makes learning way more interactive. Excited to see where you take this!
Hey thanks for stopping by and the kind words! When I saw your launch post a few weeks ago (months ago? time has become irrelevant) here on HN, my heart skipped a beat, I thought CodeMic was direct competition to CodeVideo - maybe they are, or maybe they are different enough to co-exist :) I anyway immediately dropped my email for the early access!
For a brief moment, I looked into a sort of VS Code plugin for CodeVideo but I realized it would be tough with things like mouse and animating typing directly in VS Code (unless I did a complete fork like the Cursor path). But I wasn't quite ready to take all of that on.
But yes, I think it's a huge latent space that hasn't been addressed anywhere in the market simply because you need to go half insane to take something on as complex as replayable state management for the IDE.
I agree that it's a huge space and believe there is demand for better presentation of educational material for programming beyond algorithms that fits in a slide.
I do think that our approaches are a little different and time will prove which is more effective, or perhaps both in their own ways.
For example, CodeMic aims to replace books and blogs for discussions of large codebases and showing changes to code over time, but CodeVideo seems to enhance the experience of writing books and blogs (among other things) by ensuring correctness of the code for example. There's a lot you can do there with that which I never really thought about and is out of scope for CodeMic.
If the format is open, perhaps CodeMic and CodeVideo can even import from each other.
p.s. can't disagree about the insane part, but still a lot of fun ;)
> CodeMic aims to replace books and blogs for discussions of large codebases and showing changes to code over time
This is huge and something I've pondered about how to do efficiently, because what if you could forward this essential context info to something like an LLM, or even LLM / AI aside, address immediately the classic "why did we do that here, in this way, at this time?" questions about a codebase.
I could definitely see some CodeVideo / CodeMic interoperability via some sort of export :D
Add something to tell new users to click on the next button to get going. The interface is so cluttered I had no idea of where to look or what this was for and almost clicked off.
Watched the youtube video - gives a decent overview. Linking that generated video file here would be useful to give people an idea of the output up front.
This is something I wish I'd had about 15 years ago when I was teaching online. I think the group I was with would have been able to create video versions of some of our material and have another revenue stream. At the time, we were only synchronous classroom based training - 2 hr sessions X times per week. When students were engaged, it was great! When they weren't, you were just talking in to the void. Being able to package up some of our material in to these sorts of videos - but doing it in a controlled, managed fashion like this, would have been great. By contrast, we had someone make Flash files for us. Fixing any typo took weeks. :/
Ah yes... I know the pain of creating / editing / scrubbing through educational software courses... part of why I built this :) Thanks a lot for the kind words! And about the link to the video - good point! here it is:
I think this might be really cool, but when I tried clicking "playback actions" (unclear that this button means "play" and won't just take me to a list of actions) there was no sound.
Nothing is working for me. Pressing play video gets stuck on step 1. I disabled the ad blocker in case it was interfering but looks like it's something else. Firefox 135.0.1 on Arch Linux
I can't understand why your comments were downvoted. Don't let it discourage you. Congrats again on your launch and making it to HN's front page! CodeVideo is incredible and it’s clear that a lot of effort and passion went into it.
There is a $499 a month enterprise subscription hidden deep within the account page... ;) but what do you mean exactly? multiple accounts / live sharing sessions? Tied to an org's codebase?
If html is a markup language and mardown a ... mardown language, then org is all of this and much more.
I wish there was an org-mode for everything non-textual, as org-mode solves the textual part of my life quite well.

Let's see what happens...
Add something to tell new users to click on the next button to get going. The interface is so cluttered I had no idea of where to look or what this was for and almost clicked off.
Added! Also made the more advanced action buttons (keyboard / spaces) collapsed / expandable.
Watched the youtube video - gives a decent overview. Linking that generated video file here would be useful to give people an idea of the output up front.

Product looks good! Good luck to you!

https://coffee-app.sfo2.cdn.digitaloceanspaces.com/codevideo...
FYI the "watch video" button in the hero of https://codevideo.io/ doesn't work, missing the video ID.
Great catch - real link shipping to prod as we speak. Thanks for checking out the site!

Yes, the in-browser playback is quite finicky at the moment... for now the simple step-by-step and time travel buttons (next / previous) are safer...
Playback seems to be working on Chrome.. but I will make a note however for Firefox. Thanks for checking it out!
you should leave a bot comment “codevideo is the greatest thing i’ve ever seen"
:D lol well at least we know this wasn't generated by an LLM, that's for sure (sorry everyone, my friend's spam post)
very interesting !

Org-mode is an Emacs package which combines a literate programming environment with an office suite and a productivity suite.
If html is a markup language and mardown a ... mardown language, then org is all of this and much more. I wish there was an org-mode for everything non-textual, as org-mode solves the textual part of my life quite well.
