MagicQuit – closes apps when you don't use them anymore (free)

In plain words

MagicQuit is a free, open-source macOS application that automatically closes apps you haven't used in the last 12 hours, with a customizable time threshold. Designed for Mac users who accumulate many open applications in their Dock, it offers a simple, lightweight solution that uses minimal CPU power and operates entirely offline. The app prioritizes a clean, straightforward interface while solving the problem of application clutter without requiring extensive setup.

Automatically closes apps when you don't use them anymore. Enjoy a cleaner MacOS desktop, more free memory, and enhanced battery life. MagicQuit automatically closes apps when you don't use them anymore. It's that simple. MagicQuit won't forcefully close apps. When there's unsaved data, the app will ask you to save it. Simply uncheck the box next to the app name in the menu bar. MagicQuit will never close this app again. System processes like Finder or Spotlight will never be closed. It's free. With no ads, no in-app purchases, and no subscriptions. No. MagicQuit is 100% offline and doesn't send any data to any server. It's open source, so you can check the code yourself .

In the maker’s words, at launch

I often end up having 15+ applications open in my Dock. And, unfortunately, I tend to never close them. While Arc Browser does a great job for browser tabs, I didn’t find any fully satisfying solution for MacOS. One used way too much power and the other one would have taken quite some time to set it up. So instead I…

  Built this for macOS because I wanted app switching to feel faster and more flexible than the default Command-Tab flow. DashPane combines app switching and launching in one flow, with: • customizable app shortcuts • fuzzy search for apps and windows • sidebar access • edge gestures • more consistent Command-Tab behavior • appearance, menu bar, and haptics settings This is the v2 update, shipped about a month after launch. A lot of the changes came from early user feedback. Site: https://www.dashpane.pro/

  Talanoa▲346

  Hi 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…

  LLMs can generate valid JSON 100% of the time▲854

  Outlines is a Python library that focuses on text generation with large language models. Brandon and I are not LLM experts and started the project a few months ago because we wanted to understand better how the generation process works. Our original background is probabilistic, relational and symbolic programming. Recently we came up with a fast way to generate text that matches a regex (https://blog.normalcomputing.ai/posts/2023-07-27-regex-guide...). The basic idea is simple: regular expressions have an equivalent Deterministic-Finite Automaton (DFA) representation. We…
