Codédex | Codédex Update - Q2 2026

Happy summer! It's your boy Sonny again with a big update. We've been heads down and hyper-focused this past quarter and hit some major milestones: Codédex crossed 2M users and reached profitability all three months.

Codédex

Happy summer y'all! ☀️ It's your boy Sonny again with a big update.

We've been heads down and hyper-focused this quarter. Split the quarter into two sprints and hit some major milestones: Codédex surpassed 2 million users and for the first time ever, we were profitable in all three months of the quarter. Back to back, driven entirely by subscription revenue.

It took four years, but we're here. 🥲

Let's dive into what changed, and how we got here.

# Builds Editor v1.0

I'm still heart-eyes over this. 😍

Meet your new online code editor... ✨Codédex Builds✨.

Builds has been around for a bit, and now it's getting the love it deserves. Over the past few months, our Product team has been heads down rethinking the experience from the ground up.

The goal was simple:

Build a free online code editor that's genuinely delightful to use.

We've always believed the web should have a world-class coding playground. Editors like Glitch and OG Replit inspired countless technologists (ourselves included), and we wanted to help carry that spirit forward with an editor that's approachable, fun, and built for today's builders.

Here's what's new in Codédex Builds:

  • 📁 Multi-file projects: Organize your code across multiple files and folders.

  • 🖼️ Asset uploads: Add images, videos, audio, text files.

  • ⚡ Live preview: Edits show up instantly.

  • 🌐 Public URLs: Publish to your-build.codedex.me and share the link.

  • 🏷️ Custom subdomains: Pick your own slug or let us generate one for you.

  • 🧚 Lumi: Get help from your AI companion bot.

  • 🔀 Remix: Fork any public Builds and make it your own.

Whether you're learning to code, prototyping your next idea or MVP, or sharing something you're proud of, Codédex Builds is ready for you. ✨

## Builds Landing Page

To spotlight v1, we added a logged-out view of the Builds landing page: codedex.io/builds

And if that's still not enough, here are some Builds examples:

This release was a HUGE effort behind the scenes, and we're incredibly proud of what the team shipped. More importantly, it lays a strong foundation for everything we're building next.

# Community Updates

We brought the feed to the User Dashboard!

Another focus last quarter has been improving our On-Platform Community (OPC) and making it easier to discover what other learners are sharing.

We added three new community features:

  • 🔥 From the community: A horizontal scroll in the User Dashboard.

  • 🎠 Image carousel: You can now include up to 5 images in a post. Example.

  • 📰 Tech News: Added a Tech News channel and in the User Dashboard.

We're excited to keep iterating on this~

# Course Discovery

One of the most common questions we get is: "I finished X, what should I take next?"

Until now, answering that question wasn't always obvious. So last quarter, we focused on improving course discovery, from the Course Catalog to the moment you complete a course.

## Course Catalog Updates

Jackie's Figma designs.

We introduced 6 curated Learning Journeys to help you find the right path based on your goals instead of browsing course by course. Whether you're looking to become a SWE, dive into AI, or build your first game, there's now a guided roadmap waiting for you.

Our current Learning Journeys include:

  • 🌐 Web Development

  • 📊 Data Science

  • 🤖 Artificial Intelligence

  • 💾 Computer Science

  • 🕹️ Game Development

  • 🎨 UI/UX Design

Each journey groups related courses together, making it easier to understand what to learn first, what comes next, and how everything fits together.

## End-of-Course Experience

This roadmap UI is so clean. 👌

Finishing a course shouldn't feel like reaching a dead end. 🎓

Jackie designed a brand new end-of-course UI that helps you seamlessly discover what to learn next. Instead of sending you back to browse the catalog yourself, we'll recommend the next logical step based on the course you just completed.

The goal is simple: keep your momentum going while making it easier to continue learning.

# Club Retention: 93%

So what did all of this achieve? 93% of Clubbers now stay subscribed after their first month, which is wild because we just raised the prices a few months ago. 🤯

By edtech standards, that's now in the "excellent" territory. But I've always told the team that we should benchmark ourselves against the best of the best (Netflix, Spotify, World of Warcraft are all 95%+). Let's keep doing what we're doing and just keep swimming. 📈

# 🦾 Generative AI Course

Our newly revamped GenAI course with Python is OUT NOW. 🧚‍♂️ Learn how Large Language Models actually work under the hood. Authored by our Founding Engineer Dharma.

This course also introduces a new learning environment for non-coding exercises: the narrative & instructions on the left, and our Lumi chat interface on the right. Yep, you heard that right: we've made Lumi an interactive part of the course. We might be the first platform to do this!

# 🖼️ UI/UX Design Course

UI/UX Design course is OUT NOW. Authored by Jackie, our Sr. Product Designer! 👩🏻‍🎨

This is our first ever non-coding course so we are beyond excited. We studied numerous popular design courses and tried to take the gold nuggets from each to create THE course for y’all.

We hope you like it! 🫶 Already got some dope submissions (example1, example2).

# ⚡️ YouTube Series & Blogs

Speaking of the UI/UX Design course, it came with six videos. So we created a UI/UX Design YouTube playlist. Here’s the first episode:

We released more episodes (#4 and #5) of our Meet the Codédex Crew series, giving you an inside look at the people behind Codédex.

# Looking Ahead: A Brand New Chapter

We are officially entering a new era of Codédex. 🎺🎶

For the past four years, we've been in survival mode – trying to build something people love while making sure we'd still be around to build it tmr. Every week was a race against the clock.

Now, for the first time ever... we have a little room to breathe.

Crossing 2 million learners and becoming profitable back to back are strong signals that what we're building is sustainable. It means we can spend less time worrying about revenue and more time obsessing over making Codédex better and thinking more long-term.

So Q3 is all about quality of our core product.

Better courses. Better features. Better experiences. More bug fixes. More audits. More polish.

If the first chapter of Codédex was about survival, this next chapter is about attempting to build the greatest tech education platform the world has ever seen and redefining what online learning and digital spaces can be. It's time to raise the bar higher and be different. To push boundaries and pursue our vision unapologetically. We made it through the hardest part and it's time to play.

So... to everyone who joined us along the way:

Thank you for learning, practicing, building, and being part of our community.
Thank you for caring about human creativity.
Thank you for supporting our team.
Thank you for believing in this dream that we’ve been working so hard to make a reality.

From the bottom of our hearts... thank you for everything. 🙏

See you next quarter.

- Sonny
