Hi friends! I'm Sonny, Founder & CEO at Codédex. (づ。◕‿‿◕。)づ:・゚✧

We had our first Product Hunt launch in 2022 with a prototype. Now, in 2025 and 1 million learners later, we’re back – bigger, better, and with a brand-new animated launch video to celebrate this milestone.

So who are we? We’re a ride-or-die team based in Brooklyn, NY. Collectively, we have taught Computer Science at Columbia, NYU, CUNY, and we're educators and game devs working tirelessly on this for the past three years:

I couldn’t be prouder of what we’ve built together, and coudln't be more honored to share it with you... Codédex v1.0, a love letter to technology, to creativity, and the ways they keep us together, despite everything. 💌

Hope you enjoy it and lmk what you think! ⋆˙⟡

I remember how I stumbled upon Codedex for the very first time here on Product Hunt (and completed several courses) :) Keep doing a great job.

Sonny Li

@busmark_w_nika  Oh snap! Which courses did you take? Yep, we came a long way since then. 🥲

Nika

@sonnynomnom Basics HTML, CSS, maybe 2 years ago. Remember how you wrote in one chapter how to "hack" a website and rewrite things on the page (via Inspect option) :D

Cruise Chen

Loving the whole XP and badge system—turning coding into an actual adventure is genius, tbh. Makes learning way more fun than another boring tutorial, fr!

Sonny Li

@cruise_chen Appreicate it, Cruise! Means a lot 🙏

1M learners is huge—congrats! From a potential learner’s view, I care about feedback loops . How does community learning work at scale—do you run mentor feedback, peer code reviews, or cohort sprints, and how do you keep moderation beginner-friendly?

Sonny Li

@jaredl Great questions, Jared! We run monthly workshops (in fact, there's one tomorrow on Resume Reviews!), and every Checkpoint and Final Projects for Clubbers are reviewed by real human experts. We've also got a private, beginner-friendly Discord community of 38k members you can unlock at 100 XP. The bar of entry keeps it super collaborative and welcoming. While we’ve paused cohorts two years ago, it’s something we’re still considering for a higher-tier subscription. Hope that helps~

Whoa, love the adventure vibe here—learning to code always felt intimidating to me, but turning it into a journey? That’s genius. Is there a community aspect too?

Sonny Li

@joey_zhu_seopage_ai Ofc! We have an on-platform community as if Tech Twitter + Discord had a baby:

Jorge Marchena Diaz

I have three months on the platform and it was a blast to learn in a really fun way ! I will keep learning and shouting out how amazing is Codedex! So thanks for you hard work!

Sonny Li

@jorge_marchena_diaz Love to hear it, Jorge. Thank you for learning with us. ❤️

Bhavya Arora

Codédex turned learning to code into an actual adventure XP, badges, and a friendly community make every lesson feel like progress, not a chore.

Niladri Hazra

Congrats on the launch, team! Love the XP + badges and the whole “adventure” vibe...makes learning to code actually fun.

Glad that we’re launching on the same day! 🚀

Jackie Liu

So excited for this launch! and to bring ya'll more moments of immersive storytelling and worldbuilding 🗺️🙏✨

Lien Chueh

Excited to be launching on the same day as Codédex! As someone that's fallen off Codecademy so many times, I'm very keen to try this out to see if I can trick my brain to keeping up with a regular routine of practicing coding!

Sonny Li

@lienchueh Heck yeah! I worked at Codecademy for five years, so well aware of the shortcomings and are trying to fix that here at Codédex. Yes please! Def try out our flagship Python course and lmk what u think. :)
