NanoLog - The zero-bloat changelog, roadmap & feedback widget for SaaS

Hey Product Hunt! 👋 I'm Aaron, the solo technical founder behind NanoLog. As an engineer, I care deeply about performance and realistic pricing. Whenever I wanted to add a release notes or feedback widget to SaaS projects i have worked on in the past, I was forced to compromise or be shook by the addons and costs. The incumbent tools in this space are incredibly feature-rich, but they usually come with massive, bloated JavaScript bundles that tank Lighthouse scores. Worse, their stylesheets almost always conflict with the host app's global CSS, leading to embarrassing visual bugs. On top of that, founders usually end up having to stitch together and pay for 3 different tools just to handle release notes, roadmaps, and feedback separately. I engineered NanoLog from the ground up to solve this. It’s a unified 3-in-1 platform built specifically for speed, privacy, and developers. Here’s what makes NanoLog different under the hood: 🛡️ Style Safety and Isolation: The widget is a native Web Component. Your host styles can't bleed in, and our styles can't leak out. Zero visual bugs, guaranteed by using the Shadow DOM. ⚡ Ultra-Lightweight: The entire dependency-free bundle is under 17KB (gzipped). It won't hurt your SEO, Core Web Vitals, or page speed. 🎯 JSON Cohort Targeting: Only show specific release notes to specific users based on their data payload (e.g., show "Enterprise Patch" updates to admins only). 🔐 Privacy-First Visual Feedback: Users can attach screenshots to bug reports. Our widget uses client-side HTML5 canvas processing to automatically blackout PII (emails, phone numbers, passwords) before the image ever leaves their browser. 🤝 Secure HMAC Voting: Enterprise-grade signature verification so malicious users can't spoof votes on your roadmap. 🐛 Auto-Diagnostics: When users report a bug, we automatically capture their OS, Browser, Viewport, and JS Console Errors. No more asking "what browser are you on?" We are replacing separate, expensive subscriptions with one lightweight, highly-engineered tool. We have a generous free tier, and to celebrate our launch today, we’re opening up a limited "Founders Tier" which gives you 6 months of Pro for a single $49 upfront fee. There is a live interactive sandbox on our landing page where you can play with the CSS isolation and cohort targeting right now. P.S. I’m based in the UK and heading into my day job right now! 🇬🇧 I'll be reading everything on my breaks, but I will reply to every single comment and question the second I clock out tonight - try my hardest not to crash over the inevitable feedback loop. I would love to hear your feedback, feature requests, or answer any technical questions you have about how it was built! Let's chat! 👇🙌
