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."

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

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

Brilliant app. You can consider adding desktop app like Whispering did for voice typing, you have similar idea. https://github.com/EpicenterHQ/epicenter

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

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

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

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.
