Show HN: I open sourced the QR designer from my failed startup
My designer is somewhat special, if I do say so myself, as it allows you to put arbitrary designs in the middle area of the QR while still being totally scannable.

Show HN: I built a gallary of 200 B2B SaaS pricing pages
I'm obsessed with pricing page design and optimization.<p>So I went ahead and made a collection of 200 B2B SaaS pricing pages so that other B2B founders can have an easy-to-use resource to go to for inspiration.<p>Hope someone finds it useful!
Show HN: Open-Source Alternative to DocSend
hey hn, i’m alana, founder of basecase and creator of docbase www.getdocbase.com<p>docbase is an open-source alternative to docsend, which lets you securely share documents and track engagement in real-time.<p>with docbase, you can upload any document, get a secure link (with or without a password or expiration date), and view who interacts with it and when. one main use case is for founders to send their memos/decks to potential investors. as a founder and investor myself, it’s a tool i use all the time to both send and receive pitch documents.<p>the idea came from a tweet [0], which immediately made me ping @kiwicopple with excitement. i raced to put together a very basic version 1.0 in a few days and launched it last night. luckily, it actually wasn’t too difficult using supabase for the database, authentication, and storage, next.js app router, shadcn ui [1], and vercel hosting.<p>i’m already working on some updates for version 2.0, like improving page load performance, adding notifications, and enriching analytics. it’s entirely open-source [2], so anyone can contribute and help me make it better.<p>i’d love your feedback, so hit me up on github or twitter with your thoughts!<p>[0] <a href="https://twitter.com/mfts0/status/1660980644065730561?s=20" rel="nofollow">https://twitter.com/mfts0/status/1660980644065730561?s=20</a>

Show HN: fastgron: A JSON to GRON Converter That's 40 Times Faster Than Gron
Hello HN! I want to introduce fastgron, my new project.<p>fastgron is a JSON to GRON converter, built to be incredibly fast – it's 40 times faster than Gron. GRON is a tool for making JSON greppable, but it can slow down with larger files. With fastgron, even a 200MB JSON file can be converted in just 1 second.<p>Key features include streaming conversion for memory efficiency and an optimized path reconstruction for faster operations. It leverages C++ and the simdjson and fast_io libraries for speed.<p>I welcome all feedback, suggestions, or questions. Thank you!

Codictionary: A newsletter that explain tech terms in plain, everyday language
Hey there! As a software developer, I've always wished that my clients, managers, directors, and stakeholders could get a better grasp of programming. I know they can't become coding gurus overnight, but wouldn't it be awesome if they could at least understand terms like APIs, caching, and variables? I think it would make communication a whole lot smoother and help us have more meaningful conversations.
I decided to create a newsletter that explains all these tech terms in super simple language!<p>At first, I tried to make a newsletter just for my clients. I wanted to bridge the gap between tech-savvy folks like me and those who aren't as familiar with the ins and outs of programming. But then it hit me—why not make it available to everyone who wants to understand the tech world without having to learn how to code? So, I revamped it to cater to anyone who's curious about technology.<p>Each edition of the newsletter focuses on a specific tech term or concept. We'll break it down, ditch the complicated jargon, and give you real-life examples that make it all crystal clear. My goal isn't to teach you programming (that's a whole different ball game). Instead, I want to give you the knowledge you need to have better conversations and a deeper understanding of the tech that shapes our world.<p>So, whether you're an entrepreneur who wants to connect better with your tech team, a project manager looking to understand what the developers are talking about, or simply a tech enthusiast who wants to dive into the digital world, hop on board and let's make tech simple together!

Show HN: A pixel art puzzle game for mobile using PixiJS
The idea for this pixel art puzzle game came from playing Triominos, and wondering what would happen if you replaced numbers with colors. A few mutations later, and it became a mobile game where you click a piece to turn it in place, to recreate pixel art.<p>I built the basic idea in just over an hour on Twitch.<p>Dev-wise, I used a homebrew Typescript game engine I created, called Booyah (<a href="https://github.com/play-curious/booyah">https://github.com/play-curious/booyah</a>). The graphics are all rendered using the awesome library PixiJS.<p>What do you think?

Show HN: HNRelevant – Show related HN submissions in an integrated sidebar
While browsing Hacker News, I wished for an easier way to find related submissions (instead of googling and going back and forth). So I made this small chrome extension that automatically shows relevant submissions on page load. It's intergrated as a sidebar right in the page (for ease & native look), with customization options for fine control.<p>It's based on HN algolia search API[1] and uses the submission title as its initial query with the ability to customize the query if you're not satisfied with the initial results.<p>Originally, I took it as an opportunity to try my hands at creating a browser extension, but I was quite satisfied with the result and so I decided to release it.<p>[1] HN algolia search API: <a href="https://hn.algolia.com/api" rel="nofollow">https://hn.algolia.com/api</a>

Show HN: Open Fire Serverless CI
Hello, HN community, I'm really excited to show you Open Fire a serverless CI, how does it work? relying on serverless technologies (firecracker) we can spin up a new VM in less than 200 ms running in a more powerful and newest CPU on the market, just change 1 line of code on your GitHub Actions Workflow and you're up and running!
You can see our use case, where we implemented Open Fire in the NextJS repo taking down build time from 1 hour 17 minutes to 26 minutes which is a 66 % of improvement without any engineering effort! [1]<p>The value of a CI/CD Pipeline is inversely proportional to how long the pipeline takes to run and is a limiting factor for companies to release quickly and often.<p>For a little bit of background, I have been working in the CI/CD space for the last 9 years in small startups, my own CI/CD startup for mobile games, and big enterprises like PayPal and Binance, and you see the same pattern emerges<p>In today's life developers are pretty good when they're building new features on their local machines, they have top-edge hardware like MacBooks with tons of core and RAM, but when they push and need to run all CI/CD steps building (multi-arch x86, x86_64, ARM), unit testing, e2e they start to feel very frustrated with the state of the art of their CI/CD pipeline because those will be running on some cloud provider crappy VM that has between 2vCPU 4 GiB to 4 vCPU 8 GiB of RAM, is in that place when they see that their local workflow from 2 minutes build time will become something in the range of 30 minutes to 1 hour! And if you want to migrate to self-hosted CI you will get:<p>High cost of idle infrastructure waiting to pick up jobs to run.
Big queues for accessing the resource to run your pipelines, because everyone is working at the same time frame the high demand overlaps and you can't scale your self-hosted solution that fast without building a team of ~ 20 people.
Spent all day installing and updating all the dependencies of the VM and now have to maintain the software packages installed on that machine
Companies tend to have 3 different kinds of CI/CD platforms inside them, legacy systems using Jenkins and for new systems GitHub or GitLab, and Buildkite, so you need to create and maintain new runners for all these CI/CD systems, pre-install software for all the build pipelines that may run in your runner
Now you have a new platform to develop, update and support every day for the whole company.
And the list goes on<p>[1] - <a href="https://open-fire.notion.site/Open-Fire-Serverless-CI-7884796e00e84dd082b523f66df04155" rel="nofollow">https://open-fire.notion.site/Open-Fire-Serverless-CI-788479...</a><p>Thanks for reading, if you want to try us, want to say high, or give us some feedback just ping me jean _at_ open-fire.dev<p>- Jean
