A directory of open source alternatives to proprietary software
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!
A directory of open source alternatives to proprietary software launched on March 8, 2024 with 156 votes, #345 of 4,270 launches that month and more than 95% of that year's launches. The site was not reachable when checked in September 2026.
In plain words
OpenAlternative is a community-driven directory that lists open source software alternatives to proprietary applications. Built with Astro, it serves developers and software users seeking free, open source replacements across various categories. The directory allows the community to contribute and discover alternatives, making it a crowdsourced resource for those looking to switch from commercial software to open source options.

Hi guys, I want to share the recent project i developed. I built AlternateOSS, a directory of free, open source alternatives and competitors to popular software. Currently, i have listed 200+ tools so far and organized them carefully based on their main functionalities. I ranked them based on its category relevancy and feature completeness. Some technical details & features: - fully static site built with Astro - View Transition API for smooth navigation - Instant/static search with Astro static endpoints If you have an open source project that can be an alternative to popular software,…
I'm building an open-source Amazon2022 · openship.org · ▲1,335A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…

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…
