SpinWin – A macOS menu bar app to visually rotate or spin any window
SpinWin is an open source menu bar app to visually rotate any individual window. You can rotate / spin as many as you want one by one. I was scrolling reels when one came on where the content creator suggested "turning the phone upside down" for a portion. I was sitting at my mac, and decided to see if I could find something that did this. To my surprise, nothing exists, so I decided to build it. Turns out macOS doesn't provide any public API to do anything like this, so I wound up using the Accessibility API to move the target window offscreen, where it keeps rendering. Then we capture…
SpinWin – A macOS menu bar app to visually rotate or spin any window launched on July 25, 2026 with 37 votes, #665 of 24,623 launches that month and more than 95% of that year's launches.
In plain words
SpinWin is an open source macOS menu bar app that visually rotates individual windows on demand. Built in Swift with an MIT license, it uses the Accessibility API to capture window contents and display them on a transparent overlay that can be rotated at any angle. The app was created to fill a gap in macOS functionality, allowing users to spin windows for viewing content in different orientations, similar to rotating a phone.

macOS menubar app that visually rotates or spins another app's window, using ScreenCaptureKit to fake what macOS has no API to do - alokdhir/spinwin
A macOS menubar utility that visually rotates a selected window by any angle (90° increments, arbitrary angles, or a continuous spin). macOS has no public API to rotate another app's window . Real rotation would require private SkyLight calls ( CGSSetWindowTransform ) with System Integrity Protection disabled — not worth it. Because it's a layer transform, any angle works — the overlay is sized to the rotated content's bounding box so nothing clips, and a diagonal-sized square is used while spinning. The easiest way to get SpinWin is the latest release — the download is signed with a Developer ID and notarized by Apple, so it launches without Gatekeeper warnings. Or build it yourself:…from github.com

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…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
