Stop paying to record your screen. Onyx is a privacy-first, studio-quality recorder that runs entirely in your browser. No servers, no uploads, and no "5-minute limits." Why I built it: Most tools force cloud subscriptions or downgrade quality. Onyx respects your privacy, giving you raw, high-bitrate 4K video instantly. Free forever. Built for creators to share work without friction.

Hey Product Hunt! 👋 I’m Suleyman, the maker of Onyx. I needed to show my editor how to edit a specific video, which meant recording a 30-minute+ walkthrough with my face, audio, and screen. When I searched Google, everything required a new account, monthly subscriptions, and annoying time limits. I realized I only really need a screen recorder a few times a month, and I didn't want to be locked into a subscription just for that. So I spent November 19-20th making Onyx, a forever-free screen recorder. Onyx is my answer to subscription fatigue: - No Account: Record right away. - Privacy: It uses your computer's storage, not a cloud server's. - No Limits: Record for 5 minutes or 5 hours. - No Watermarks: Just clean 4K video. - Quick Edits: Trim the video to cut out the "millennial pause" at the start. I’d love to hear what you think! If you find any bugs or have a feature request, let me know in the comments. I'm shipping updates all day. 🚀 Happy recording! Suleyman

Hey Saleyman. When I started recording, my computer froze for a moment. It probably uses quite a lot of memory in the browser on a regular computer.

@jakubpacanda Hey Jakub! Thanks for the honest feedback.

You are spot on, because Onyx runs 100% locally (to ensure privacy) and defaults to high-bitrate 4K, it can be memory-intensive on the browser.

I am adding a "Performance Mode" (1080p) to the roadmap for the next update to make it lighter on RAM. Appreciate you testing it out!

Can I move the position of the recorder or maybe do a resize?

This is really great, by the way. Bookmarking for future use.

@chilarai Hey Chilarai! Thanks for the bookmark! 🙌

You actually can move and resize the camera bubble right now!

There are specific toggle buttons on the camera overlay that let you switch between Small and Large sizes instantly.

If they weren't easy to spot, that is great feedback for me, I'll work on making those controls more obvious in the next update!

What is an advantege over the built-in macos feature with a single shortcut and 2 sec to start recording?

@pavel_khromov Hey, Pavel! Onyx overlays your camera (resizable/movable) so you can talk through the video. macOS is screen-only.

The product is genius. Is there a way to share the recording without downloading the file?
