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

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 🙏

JaredL

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~
