Record and playback interactive walkthroughs of your codebases
I feel like the process of learning codebases should be more guided, interactive, and integrated into your editor. Not buried in documentation. To improve onboarding, and make it easy to create such learning assets, I created a "tutorial recorder" for @code. It's called Code Tour

I built an interactive course that helps you learn Vim faster2022 · vimified.com · ▲344Hey show HN! This course came about as a result of wanting a more targeted way of practicing using new vim commands I wanted to pick up, rather than just trying to use them in my regular code editing sessions. When I would try to use new commands during code editing, my productivity took a hit because I was trying to do two different things at once: thinking about code vs practicing my muscle memory. So, I made a separate environment for practicing, one that had an interactive editor, progress tracking, and achievement goals to let me see which areas I should work on, like speed and…
CodeMicFeb 2026 · codemic.io · ▲52With CodeMic you can record and share coding sessions directly inside your editor. Think Asciinema, but for full coding sessions with audio, video, and images. While replaying a session, you can pause at any point, explore the code in your own editor, modify it, and even run it. This makes following tutorials and understanding real codebases much more practical than watching a video. Local first, and open source. p.s. I’ve been working on this for a little over two years and would love to hear your thoughts.
ScreentellJan 2026 · screentell.com · ▲164I’m an indie dev, and every time I launch or ship anything, there’s this familiar mini-hell: “now I need to record a decent demo…” You probably know the drill: - install yet another screen recorder - mess with audio input / system audio - accidentally capture your messy tabs or notifications - re-record because you forgot to hide something sensitive - open a separate editor just to crop, zoom, or add a simple arrow After doing this a few too many times, I realized I was spending way more time fighting tools than making the actual demo. And most of my needs were pretty simple: short…

- IMI made an in-browser code editor with code replay and REPL2023 · logicboard.com · ▲87
I made a Logicboard.com — A collaborative code editor with code-replay feature. Code-replay lets you run the coding session like a movie, I wrote a blog post on how I implemented this: https://logicboard.com/blog/code-replay You can try out the demo here: https://logicboard.com/demo/:replay And play around with the code editor here: https://logicboard.com/demo/ Logicboard also has an REPL shell, just type "start()" and hit enter in the output area.
Stage – Putting humans back in control of code reviewApr 2026 · stagereview.app · ▲130Hey HN! We're Charles and Dean, and we're building Stage: a code review tool that guides you through reading a PR step by step, instead of piecing together a giant diff. Here's a demo video: https://www.tella.tv/video/stage-demo-1pph. You can play around with some example PRs here: https://stagereview.app/explore. Teams are moving faster than ever with AI these days, but more and more engineers are merging changes that they don't really understand. The bottleneck isn't writing code anymore, it's reviewing it. We're two engineers who got frustrated with…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
