Show HN: Linux and iPhone Continuity (iMessage / SMS) https://bit.ly/4wGX6mi

Show HN: Linux and iPhone Continuity (iMessage / SMS) After switching to 100% Linux a couple of years ago there was basically only one thing I missed about macOS and that was what Apple calls "Continuity". It's where you get texts, notifications, clipboard sync, file transfer (to/from) the iPhone from the Mac desktop. Especially that thing where OTP codes via text autofilled into the browser form I was waiting on. It took about 4 months of work: - reverse-engineering Apple/iOS Bluetooth behavior - MAP / OBEX - Bluetooth LE + Wi-Fi working together - iMessage through the iPhone's own cellular/iMessage stack - iOS app, Linux daemon, GTK app, Thunderbird/Firefox extension - no Mac involved But it is now something I'd love to show people. Contributions/bugs/feedback welcome! https://bit.ly/4wFJzvb August 20, 2026 at 05:53AM

Show HN: Mail client optimized for self-hosted email across multiple domains https://bit.ly/4qs7GvS

Show HN: Mail client optimized for self-hosted email across multiple domains As someone with a clean IP range and ADHD, I manage my inbox by splitting across a variety of accounts for a variety of domains. I’ve never really found a client that scratches all my itches, so I spent some time making one and it’s now become my daily driver. It’s optimised to be visually simple and highly configurable for things like colour, folders/subfolders, sorting and tweaking the search query function to better match what you search for often. There’s also some little nice-to-haves like a purpose-built PWA, bulk domain onboarding, MCP and dark mode. It’s fully self-hostable, open source and free of any AI bloat/VC fodder. Not trying to sell anything but rather make something un-shitified and simple to use, would love some feedback if you’ve given it a try! :~) https://bit.ly/4xdIHPw August 20, 2026 at 02:55AM

Show HN: A new way to read books, magnifying in and out https://bit.ly/4quXtyL

Show HN: A new way to read books, magnifying in and out After watching The Odyssey, I thought it would be cool to check out some scenes from the source in detail, but I don't have time to read the whole book. So I came up with a sort of zoom/microscope, that allows to see the whole book at a glance and then zoom in (by pinching) on the part I'm interested in. I can do so down to the actual source text and get the authentic feel the author intended, at the same time I better understand where am I in the text and also the character and places are clickable so I can quickly orient myself on the context. Moreover each character has relationships listed and a map of relationships can be opened from there https://bit.ly/4qthZzF https://bit.ly/4qtw1Bq August 19, 2026 at 11:21PM

Show HN: Draw.city – geography game where you circle the target population [US] https://bit.ly/4gfdV1d

Show HN: Draw.city – geography game where you circle the target population [US] The core idea is, you draw a circle on a satellite view map and it tells you the population inside + more info. The home page is a daily challenge, I've backfilled some "past challenges" so there's more than just the past couple of days to play, and there is also a free-draw mode that tells you population + some census demographic info & points-of-interest data from OpenStreetMap. In most cases, the data comes from taking the census blocks w/ centroids contained in your circle and summing their population. Demographic info is slightly more complex as it's not sourced on blocks, so we allocate population-weighted fractions of a source territory's published census values into the drawn territory. Happy to answer any questions about the data or the technical side. The game/app only covers US areas at the moment, I'd like to add international data in the future! I am re-submitting this as a proper "Show HN", as I left the 'Show HN' text out of the title the last time I submitted https://bit.ly/46dVKUY August 18, 2026 at 11:14PM

Show HN: AI-generated music box version of any song (for baby) https://bit.ly/4g5aX0G

Show HN: AI-generated music box version of any song (for baby) title basically covers it. project #2 from my paternity leave. My partner & I got frustrated with hearing Brahm's Lullaby and Wheels On The Bus repeatedly. I also stand by that babies can enjoy adult music just as easily as they can enjoy "kids music". But most adult music is too dense/complex for babies to understand, so I created this to generate baby-friendly, slowed down versions of songs that we like to play for our baby & sing along with. Uses BS-roformer for stemming out the input audio + spotify Basic Pitch for transposing to midi. Still needs some work, kinda sounds like a drunk little music box version of the original but very fun. https://bit.ly/3Sfk5GE August 18, 2026 at 12:14AM

Show HN: Classifier and browser extension to detect rule violating HN comments https://bit.ly/4ielCav

Show HN: Classifier and browser extension to detect rule violating HN comments I love HN, but lately I have been sick of reading the same dismissive criticisms over and over again. Along with political arguments that have been litigated to death, people's issues with smooth scrolling on blogs, etc. Many of these comments do not get flagged for whatever reason. So I made a service to automatically classify whether comments violate (a modified form of) the HN guidelines automatically. In addition there's a Chrome extension to collapse these comments (if they violate your score thresholds) so you don't have to read them too. You can also just watch guideline violating comments as they are posted on the home page. Here's more info on how it works: https://bit.ly/4ifpatb https://bit.ly/4zpdGtk August 17, 2026 at 05:04PM

Show HN: A visual ping utility that is pretty As a network engineer, I use ICMP every day. The default ping utility is ugly, I used a prettyping instead. But it got some bugs, isn't configurable and need bash. So I made my own. I hope it will help some other IT guy.

Show HN: PageSieve, a web scraping browser extension https://bit.ly/45rF6B8

Show HN: PageSieve, a web scraping browser extension PageSieve[1] is a browser extension for scraping data from different websites from within your browser. Currently it's Firefox only but I am open to porting it to other browsers if that's something people want. My original motivation for this started with a desire to improve the capabilities of the selectorgadget[2] bookmarklet to support extracting as well as finding selectors. The ideal use case is when some data you need is useful but you don't want to spend the effort of writing a one-off script to extract it especially nowadays when a lot of websites need an entire JavaScript environment to load correctly which complicates scraping. Using this extension means you only need to maintain the selectors for extracting the data and don't need to worry about managing dependencies. As long as the website can be opened in your browser you should be able to scrape data from it using the extension. I have a lot of features planned as well as some rough edges that need smoothing. I use this extension nearly everyday and I hope it can make somebody else's work easier. Take a look and let me know what you think.

Show HN: Mocktail – Free, open-source mock API server with a built-in dashboard https://bit.ly/3RQ70DN

Show HN: Mocktail – Free, open-source mock API server with a built-in dashboard Hi HN, I built the first version of Mocktail years ago. I recently came back to the project, and after a pretty substantial rebuild, v4 is now out. Mocktail is a free and open-source, self-hosted mock API server with a built-in dashboard and database, packaged as a single ~25 MB binary. You can run it locally or on your own infrastructure — no account or hosted service required. You can define endpoints and responses, generate realistic data per request, customize headers, status codes and latency, and inspect incoming requests in real time. With v4, I also added MCP support, so coding agents can create and manage mocks directly, along with an optional built-in AI assistant using your own API key. Both are completely optional. It’s been fun coming back to something I built years ago and bringing it up to date. I’d love to hear what you think, especially anything you’d change or add. https://bit.ly/4ws1Iwg August 14, 2026 at 09:20PM
