Alternatives
Products that do what Octosphere, a tool to decentralise scientific publishing does
Hey HN! I went to an ATProto meetup last week, and as a burnt-out semi-academic who hates academic publishing, I thought there might be a cool opportunity to build on Octopus (https://www.octopus.ac/), so I got a bit excited over the weekend and built Octosphere. Hopefully some of you find it interesting! Blog post here: https://andreasthinks.me/posts/octosphere/octosphere.html

I have been working on Octelium for quite a few years now but it was open sourced only by late May 2025. Octelium, as described more in detail in the repo's README, is simply an open source, self-hosted, unified platform for zero trust resource access that is primarily meant to be a modern alternative to corporate VPNs and remote access tools. It can operate as a remote access/corporate VPN (i.e. alternative to Twingate, Tailscale, OpenVPN Access Server, etc...), a ZTNA/BeyondCorp platform (i.e. alterntive to Cloudflare Access, Teleport, Google BeyondCorp, etc...), and it can also…

Hi HN - My name is Andrew, and I'm a high school student. This is a write-up on StratoSpore, a payload I designed and launched to the stratosphere. The goal was to test if we could estimate physical altitude based on algae fluorescence (using a lightweight ML model trained on the sensor data). The blog post covers the full engineering mess/process, including: - The Hardware: Designing PCBs for the AS7263 spectral sensor and Pi Zero 2 W. -The biological altimeter: How I tried to correlate biological stress (fluorescence) with altitude. - The Communications: A custom lossy compression…

Sup HN, So I got tired of bouncing between Flightradar, MarineTraffic, and Twitter every time something kicked off globally, so I wrote a dashboard to aggregate it all locally. It’s called Shadowbroker. I’ll admit I leaned way too hard into the "movie hacker" aesthetic for the UI, but the actual pipeline underneath is real. It pulls commercial/military ADS-B, the AIS WebSocket stream (about 25,000+ ships), N2YO satellite telemetry, and GDELT conflict data into a single MapLibre instance. Getting this to run without melting my browser was the hardest part. I'm running this on a laptop…

Hi, Piotr here I was collecting nice open-source companies for quite some time now. Mostly to take some inspiration and learn from their code. Last week, I though it would be fun to learn this Astro thing everyone's talking about. So I thought building a directory website out of this collection was pretty good idea. After 2 days of building, OpenAlternative was born. It's a community driven list of open source alternatives to proprietary software and applications. Enjoy and thank you for your support!

In the last few years I've been doing a lot of technical writing, both for my own programming blog and others, and I've noticed there is a lack of good tools for this kind of writing. Whether that was a programming blog post or documentation, I always had to move back an forth between different editors, and sometimes even other apps for content management and the actual content publication. A lot of copy-pasting, and wasted time. Based on this experience I decided to try and build a tool that could provide a good experience for this kind of content from writing to publishing. This (I call it…

Hello HN, I've been working solo on Octelium for the past 5+ years now, (yes, you just read that correctly :|) along with a couple more sub-projects that will hopefully be released soon and I'd love to get some honest opinions from you. Octelium is simply an open source, self-hosted, unified platform for zero trust resource access that is primarily meant to be a modern alternative to corporate VPNs and remote access tools. It is built to be generic enough to not only operate as a ZTNA/BeyondCorp platform (i.e. alternative to Cloudflare Zero Trust, Google BeyondCorp, Zscaler Private…

Earlier this year, we released our open-source game engine [0] built with Rust, WebAssembly, and WebGPU. Today, we’re happy to announce the Ambient platform, which brings web deployment, server hosting, and more to the runtime. With Ambient, you can make a game, deploy it to the browser in one command, share your URL and instantly play with others, no downloads or installs needed. Our WASM use is innovative; it is being used as both a sandboxed runtime for user code, and as a way to run the entire Ambient runtime in the browser. This, paired with our ECS data model, enables a highly modular…

Over the last two years, we’ve seen just how quickly science can move when it’s conducted out in the open, and the focus is on content rather than the publishing process. We’ve built a new way for researchers and scientists to communicate and share their findings with the world - rethought from first principles, with a lot more coming soon. Free to use, and available now for anyone with a university email address. We’re whitelisting organizations that conduct and publish research on a rolling basis. Please forward feedback and thoughts to [email protected] or comment here!

I'm building Octo because I needed a tool that combined Figma’s collaboration with Illustrator and Photoshop’s tooling. As a developer, I wanted something that supports both the technical and creative sides of UI/UX design. Octo is cross-platform and built to simplify workflows for people who code and design.

We're two college students building an XR(AR/VR) native Operating System with a custom kernel. We're also Open Source so feel free to check our GitHub Repository- https://github.com/manaskamal/XenevaOS . The journey hasn't exactly been easy, we've been criticized by a lot saying that whatever we're doing is impractical and that we're too ambitious. Regardless, we've been committed to reach our goal. Here to answer all questions and doubts. Answering one question beforehand because we know someone is going to ask it - Q: Why use your own kernel/ Why don't you use…
