Show HN: React.js LLM Agent (open-source)

I've been working in the couple of months on an experiment, trying to make GPT-4 much more useful for web development / React, writing production code that is relevant to any repository without copy pasta from ChatGPT or having small snippets of auto-complete from Copilot that are not in your context.<p>The agent is taking a user story text and generating and composing multiple react components to generate the relevant screens, based on atomic design principles, with Typescript, TailwindCSS and RadixUI.<p>Is is still experimental but very interesting results, I would like to get your feedback on it! It is completely open-sourced, looking for contributors!

Show HN: Kaizen, music updated over time like software

Hi, I'm co-founder and CTO of Kaizen.<p>The project started as just a weekend project with me and a music producer friend. It has since grown into a community of artists looking to share their music more frequently and engage with their fans more consistently.<p>We've just launched on ProductHunt: <a href="https://www.producthunt.com/posts/kaizen-3" rel="nofollow">https://www.producthunt.com/posts/kaizen-3</a><p>We would love any thoughts or feedback!

Show HN: Infinity Whiteboard, Designed for Teachers

I've created a whiteboard which I use every lesson when teaching maths, though it can be used for anything. It currently has a few hundred teachers using it daily. It's designed for use with touch-screen interactive whiteboards in classrooms, and stays in sync with your phone/tablet/whatever without signup/login.<p>You can also find me on Twitter where I post updates etc: <a href="https://twitter.com/jakegmaths" rel="nofollow">https://twitter.com/jakegmaths</a><p>Some features and cool things:<p><pre><code> * Sync devices without signup - offline by default, just hit 'sync devices' and use the same code on multiple devices to sync * Touch-first - 1 finger draws; 2 finger pan/zoom; 3 finger gestures like changing pen colour * Add images - when teaching, this is usually photos of student work taken on my phone and auto-sync'd to the whiteboard at the front of the room * Add PDFs - when teaching, these are usually past paper exams which I then annotate over with the class * Zen mode - 3 finger tap or hit the ∞ icon to hide the UI; something I use every lesson so students can focus on the actual maths (there's also a fullscreen button when not on iOS) * Visualiser - often when teaching we'll work on paper with a webcam aka 'visualiser' pointing down at it; this projects that to the main whiteboard, with optional cropping, freeze-frame and snapshots * Screencast - many teachers use eg PowerPoint to teach; instead, I'll use PowerPoint in edit/design mode rather than slideshow mode, with a locally-cast cropped portion of that on the main whiteboard at the front of the room. This enables me to eg edit my PowerPoint as I go and use all the PowerPoint tools not available in slideshow mode * Instant replay - hit the play button to play back all the scribblings currently showing on the screen * Magnet mode - when sync'd with another device, use the magnet icon so the other device follows you. Most of my teaching is now via a tablet-with-stylus anywhere in the room, and as I pan/zoom around with the tablet the main whiteboard comes with me... but only when I want it to by activating the magnet * Student mini-whiteboards (MWBs) - if my students have devices and I want them to use them, I 'sync devices' then enable student MWBs and each student has a live copy of the whiteboard, and I can see what they write and can showcase any student instantly on the main board * PWA support - install as a PWA and you can download whiteboards as .iwb files which can then be double-clicked to open/edit on desktop * Free - I have no plans to charge for this </code></pre> Other things you may find interesting from a tech perspective:<p><pre><code> * The client is a single <5,000 lines HTML file, with JS, CSS, SVG-favicon all inlined (plus PDF.js lazily loaded if you add a PDF) * This is vanilla Javascript with no frameworks or libraries (except PDF.js) and no minification or build scripts - just view-source and check out how ugly all my code is! * 77.6kB for everything (except PDF support)... the size of 'modern' websites frankly disgusts me * The server is just a single ~500 line Javascript file and runs on Deno (also ported to Bun but unstable for now) and really just serves some static files, deals with websockets and temporarily stores images people add * Costs ~£5/month on Heroku * There's no database or any long-term persistence - Heroku servers restart every 24h and nothing is saved beyond that; it's all ephemeral</code></pre>

Show HN: AI SQL Copilot LogicLoop – AI to Generate, Optimize and Debug SQL

Hey folks!<p>I’m the founder of LogicLoop AI SQL Copilot. If you’re familiar with querying data, you’ve probably spent quite some time manually writing and debugging SQL queries. If you’re a non-technical business user, you will often need to wait and ask engineers to help you write the SQL to pull the data you need. If you’re an engineer, you might be overwhelmed by all these data pull requests from business users.<p>With LogicLoop's AI SQL Helper Suite, you can ask your data questions using natural language. Ask AI to discover patterns, suggest, write, fix and optimize SQL queries directly on your custom data schema. You can get results on your own data instantly. Once you have your results, you can visualize them on a dashboard or set up recurring alerts and automations. AI makes data more accessible for business users, and faster to work with for engineers/analysts.<p>Some ways LogicLoop's AI SQL Helper Suite has helped early users: - Business operations teams can find top customers to email and automate outreach - Risk analysts can discover gaps in their fraud monitoring rules to flag more bad actors - Data engineers can fix and optimize long queries to reduce costs<p>We don’t think this is a panacea that can replace data analysts, but we think this will make data analysis faster and more accessible to more people. Would love for you to give it a try and share any feedback. Thank you.

Show HN: Oneleet – Penetration Testing for SOC 2 and beyond

Hello HN,<p>Over the past months at Oneleet (YC S22), our team has been building <a href="https://app.oneleet.com">https://app.oneleet.com</a>, a compliance-focused pentesting-as-a-service platform. It allows companies to easily schedule and manage penetration tests, designed for both compliance and security enhancement.<p>We collaborate exclusively with top-tier vetted penetration testers based in NATO countries, ensuring superior quality results. Competitors like Cobalt work with just about anyone, of which they put multiple on a single engagement to ‘average out’ the quality. Despite their efforts, it is still hit-and-miss.<p>By being very selective about who we work with (many Cobalt pentesters don’t make the cut), we are very consistent in the level of insight and quality we provide.<p>Our team puts a lot of work into making sure that pentest results can be leveraged beyond security improvements. We are fully aware that with the current SOC 2 craze[1] most companies are just looking to tick their compliance and control boxes[2][3], but that doesn’t mean you can’t have both that box ticked and fundamentally improve your app’s security. Which is why we make sure our pentests serve both purposes: Present technical detail at a deep level but also provide documentation that is meant to be a sales and trust-building tool.<p>Some of the things I used to hate when I worked as a pentester myself was seeing how common it had become for pentesters to just take Nessus findings, slap a pentest report title page on it and then proudly proclaim how they found these critical ‘SSL’ and ‘HTTP Header’ findings. Not to mention how much trouble it can get you in with your auditor when they see all those criticals they don’t understand the nature of. When those auditors then require you to fix all those criticals, you quickly find yourself going down a rabbit hole of unnecessary engineering effort.<p>Great pentesters, on the other hand, use those exact same tools but know what to do with the information that they generate. Take a tool like Burp Suite, which is known among pentesters as the go-to tool for manual web app pentesting. Despite it primarily being used for manual testing, it also has ‘auto scanning’ functionality built in that is mostly useless without a human guiding the tool. More than once I heard both pentesters and clients state: “We already do Burp Suite scanning, so we have that covered.”<p>Don’t get me wrong.. there are plenty of tools that provide a lot of insight without needing human guidance. Running Nuclei[4] frequently on your web-facing hosts is a great way to spot low-hanging fruit-type vulnerabilities, but it will require you to at least have some basic understanding of what the reported findings entail, and whether the associated severities are accurate or not (CVSS scores can be very random, so using them as a yardstick can be a terrible idea).<p>This is why we’re strict about not allowing testers to inflate the severity of findings, or to revert to reporting boilerplate findings that many automated tools spit out by default.<p>If you’re interested in having a pentest performed, you can get started by going to <a href="https://app.oneleet.com">https://app.oneleet.com</a>. After registration, you will be guided through an onboarding flow after which you can schedule a call with the founding team and a pentester.<p>We’d love to get your feedback and answer any questions you might have!<p>References: [1] <a href="https://latacora.micro.blog/2020/03/12/the-soc-starting.html" rel="nofollow">https://latacora.micro.blog/2020/03/12/the-soc-starting.html</a>] [2] <a href="https://news.ycombinator.com/item?id=32018066" rel="nofollow">https://news.ycombinator.com/item?id=32018066</a> [3] <a href="https://news.ycombinator.com/item?id=32039828" rel="nofollow">https://news.ycombinator.com/item?id=32039828</a> [4] <a href="https://github.com/projectdiscovery/nuclei">https://github.com/projectdiscovery/nuclei</a>
