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.

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,…

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!

I got tired of collecting open source projects in my chrome bookmarks so I decided to compile a curated list of: - Recently active projects on GitHub - Mostly dev tools (but also productivity, analytics) - Projects which are "Alternative to X software" My bookmarks are finally empty:D If you have a great open source tool you use, I'd be glad to hear your suggestions. Also, any feedback is greatly appreciated.

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…

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.

I work on R00M 101, a Reddit-based OSINT profiler. While building it, I realized most open-source intelligence (OSINT) tools are scattered across GitHub, outdated blog posts, or random Discords. So I put together a public-facing directory of 100+ OSINT tools used by analysts, journalists, and security folks, free, filterable, and categorized by risk, platform, and use case. The idea was to make something useful and no-friction. Built with static HTML + SQL backend + a lot of caffeine. Would love feedback on how to improve the UX or tool curation. If anyone wants to contribute tools or help…

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…

Several months ago, I built a "stealth" feature that I could use. It hasn't been advertised, and I've been the only user. As I find it useful for myself, I believe others (software developers) may like it too. So, this is the first public post about it, and if it gets any positive feedback, I may put some time into promoting it more. In essence, given that you've opened a GitHub repo (there are ~225k of the more popular ones indexed as of now), you can replace "github" with "libhunt" within the URL, and you will find the top alternatives and related projects. For example, here are three…

Hi HN, We’re Brendan and Michael, the creators of Sourcebot (https://github.com/sourcebot-dev/sourcebot). Sourcebot is an open-source code search tool that allows you to quickly search across many large codebases. Check out our demo video here: https://youtu.be/mrIFYSB_1F4, or try it for yourself on our demo site here: https://demo.sourcebot.dev While at prior roles, we’ve both felt the pain of searching across hundreds of multi-million line codebases. Using local tools like grep were ill-suited since you often only had a handful of codebases…
