Show HN: Mac screen recorder that adds zoom animations from click data

snazarov92 — Tue, 09 Jun 2026 14:10:25 +0000

Hi HN, I started building my product around 2 years ago as a Chrome extension. After releasing it, I realized I would never reach the quality of desktop apps, so at the beginning of 2025 I pivoted to a macOS app. I spent 3 months rewriting the codebase for Electron. I’m still using Next.js under the hood because the chrome extension used it, but in the near future I want to switch to ViteJS since it’s lighter and I don’t need backend functionality for an Electron app.

Overall I spent about 2 years on the development. The more interesting part is tracking the cursor movements when user starts recording and transforming it into smooth cursor movements and click-driven zoom effects. I use Swift scripts for low-level cursor tracking, then run a post-processing pipeline: resampling to timeline FPS, outlier-jump clamping, stillness detection/snap-to-median, cursor-type flicker smoothing, and coordinate normalization for area vs full-screen recording. Clicks are converted into timed zoom segments with easing so playback feels intentional, not jumpy

For the video preview and export I use PixiJS. Before I used Remotion, which had the needed functionality, but the rendering was slower because it relied on a Chromium + FFmpeg pipeline. PixiJS uses WebGL so the 4k video rending is much faster. It took me about 3 weeks on switching from Remotion to PixiJS. The rendering speed improved by about 3-4x on the same projects and hardware. I was honestly relieved when it finally worked

I would never have built this product without AI assistants, since I had never built an Electron app before. Many things were not obvious to me, and my first users ran into lots of issues and edge cases I didn’t even know existed. I spent the last year fixing them.

I'm happy to answer on your questions

Yes, I've never tried ads for my app. But I will do it soon. Thank you!

My main differentiator is creating of polished screen recordings. It takes time to export the videos compared to the Loom solution where you can share the video instantly. There a big increase of indie hackers and founders. They are my main audience for now

Looks very promising! I've been doing automation testing for 5 years. Tools like Playwright already do evidence gathering. How is it different in your tool?

I love the idea! So, instead of surveys with real people, AI does the evaluations?

That's a good idea! It would be great if it also had communities with people who wants to quit the same habit. Like a supporting group hahah

Ask HN: How would you grow a screen recording app after hitting $3.5K MRR?

Hey! I’m currently making $3.5K/month from a Mac screen recording app with zoom effects. It feels like I’ve hit a plateau and I’m not sure how to grow it further.

Most of my sales come from X and blog posts on my website. I’m trying to push both, but it takes a lot of time to see meaningful results.

Any non-obvious advice on how you’d grow something like this?

How does it work? Do I need to listen podcasts using your app or I can do it on Spotify and skip the ads there?

I can imagine that in the near future we're gonna have such news almost every day, with so many people starting to build software without knowing the basics of coding.
