Show HN: I built a free, open-source macOS screen recorder with modern features (github.com)
I built a screen recorder for macOS because the one I used before broke with macOS 26 and seems to be not well maintained.<p>I think it turned out pretty cool, so I&#x27;m sharing it here: It uses ScreenCaptureKit and SwiftUI, supports ProRes 4444&#x2F;HEVC&#x2F;H.264 including alpha channel and HDR...
Ask HN: How many hours do you work per week?
Germany is currently debating part-time work and whether we need longer hours overall. I do 40h&#x2F;week and it feels sustainable. I don&#x27;t think the hours I put in are proportional to the value&#x2F;output I produce.<p>When people bring up the 996 model, I genuinely don&#x27;t get it. How does...

Show HN: Pulse – a beautiful service monitor that lives in your notch (github.com)
I built Pulse to have a quick way to see if a service is down without opening a browser or checking Slack, mails, etc. IMO, it looks beautiful and doesn&#x27;t get in the way when you don&#x27;t need it. It also supports macOS notification and you can easily mute individual services if needed.<p>No ...
Show HN: Boredom Challenge – Test and Improve Your Boredom Tolerance (jsattler.github.io)
Boredom is uncomfortable but important. I built a neat little website to test and improve your boredom tolerance. Data stays in your browser or can be exported&#x2F;imported.

Show HN: ZeroDistraction – A Firefox extension that blocks distracting websites (addons.mozilla.org)
I built a Firefox extension to block distracting websites. Similar to LeechBlockNG, but simpler. I wanted something to get started with zero configuration, which was the main reason to build the extension. Let me know if you like it or if there is anything you are missing.
Show HN: A Firefox extension to stay focused (github.com)
I built a simple Firefox extension that blocks distracting websites when you need to get things done. It&#x27;s privacy focused and ships with useful presets to block social media, entertainment and news sites, so you don&#x27;t need spend time on configuration. I hope you find it useful and get bac...

Show HN: A macOS screen recorder for the rest of us – free and open source (jsattler.github.io)
I built this screen recorder over the past couple of days. It&#x27;s lightweight and uses native macOS features through ScreenCaptureKit. It supports various codecs (ProRes4444&#x2F;422, HEVC&#x2F;H.265, H.264) and additional features such as HDR and alpha channel &#x2F; transparency. Feedback and c...

Show HN: Watts Up – a bike trainer-powered, arcade browser game (github.com)
I built a bike trainer-powered arcade browser game for parties, bike fairs and other bike-related events. The game is very easy: Every X seconds the target watts increase by Y. The person who can keep up the longest, wins. Hope you like it :)
