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!

Hey everyone, A couple years ago, I got into programming and fell down the rabbit hole of open-source software. I started realizing a lot of the commercial software I used had open-source alternatives. In 2020, those alternatives were good but not perfect replacements. With LLMs entering the scene, there are even more open-source alternatives now and they're narrowing the gap between proprietary options. LLMs also got me thinking: will people continue using proprietary or opensource applications in the future when they can build their own personal application tailored specifically for their…

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,…

A 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…

Hey HN, I am proud to show you guys that I have built an open source alternative to Azure OpenAI services. Azure OpenAI services was born out of companies needing enhanced security and access control for using different GPT models. I want to build an OSS version of Azure OpenAI services that people could self host in their own infrastructure. "How can I track LLM spend per API key?" "Can I create a development OpenAI API key with limited access for Bob?" "Can I see my LLM spend breakdown by models and endpoints?" "Can I create 100 OpenAI API keys that my students could use in a classroom…

Hey people! I have been compiling a database of opensource alternatives and I'm super proud of it so far. It serves as a searchable directory for high-quality opensource. After tons of hours I've managed to compile a database of 1000+ opensource software. I've seen other sites which have the same premise and all the GitHub Awesome Lists, but they lack in showing if the repo is active, abandoned, experimental, buggy/unstable, has a restrictive license or corporate influence like this does. Thanks for your time, if you have any recommendations for features/additions I'd love to hear.

Hey HN, we're a YC startup building an open-source, privacy-first alternative to Perplexity Comet. No invite system unlike bunch of others – you can download it today from our website or GitHub: https://github.com/browseros-ai/BrowserOS --- Why bother building an alternative? We believe browsers will become the new operating systems, where we offload much bunch of our work to AI agents. But these agents will have access to all your sensitive data – emails, docs, on top of your browser history. Open-source, privacy-first alternatives need to exist. We're not a search or ad…

Hey HNs: This is Vincent from the ILLA team. I'm sure you guys see tons of "Open-source" and "Alternative to Retool" these days. I won't deny Retool is a great product, and so are many open-source competitors such as Appsmith, Budibase, Tooljet etc. However, what makes ILLA so special? What advantages does ILLA have that allow users to choose ILLA instead of others? Well, I would like to answer those questions to all folks at HN one by one. First, we are similar to Retool, or Appsmith but we have many different our own features. We are a true open-source project all the folks here can check…
