You vibe-coded the app. Now let your users catch the bugs.
blocFeed adds in-app bug reporting to any web app with one NPM package. Users click the broken element, describe what went wrong, and submit an annotated screenshot with full technical context. You get structured, actionable bug reports — not vague Slack messages.
npm install blocfeed
// Add to your app — that's it
import { BlocFeedWidget } from 'blocfeed'
<BlocFeedWidget
blocfeed_id="your-project-id"
/>The problem
Bug reports without context are just noise
Your users find real bugs. But when they report them through Slack, email, or support tickets, you get vague messages that create more questions than answers.
Which page? Which element? What browser?
No screenshot. No URL. No device info.
More time asking questions than fixing bugs.
The difference
Same bug, two very different outcomes
User reports: "checkout button broken"
You ask: which page? what browser?
User replies (28 min later): "the one after cart"
You ask for a screenshot
User: "on my phone now, ill send later"
Screenshot never arrives
Result: No screenshot. No selector. No browser info. Can't reproduce.

Trust & Transparency
Ship fast, stay safe
Vibe coding means moving fast. Adding a bug reporting script shouldn't slow you down — or compromise your users. Here's how we keep it clean.
Zero runtime overhead
The widget loads asynchronously and adds nothing to your critical path. No performance penalty, even on AI-generated code with large bundles.
Bug reports stay in your project
Every report is encrypted, scoped to your project, and never shared. We don't sell data, don't train models on your submissions, and don't run background analytics.
No tracking, period
No cookies. No fingerprinting. No session recordings. The widget only activates when a user clicks the bug report button — nothing runs in the background.
Free NPM package
One install, zero cost. The blocFeed package is lightweight (~8 KB), has no peer dependencies, and works with React, Vue, Svelte, and Angular.
Why we built this
“I was building apps with Cursor and shipping fast — but my users kept finding bugs I couldn't reproduce. They'd say 'it's broken' and I'd spend 20 minutes asking which page, which button, which browser. I built blocFeed so one click gives me everything I need to fix it.”
Mihir Kanzariya
Founder, blocFeed
Testimonials
What developers are saying
“I shipped a Next.js app with Cursor in a weekend. Monday morning, users found 3 bugs I couldn't reproduce. Added blocFeed, and every report came with the exact element selector and a screenshot. Fixed all 3 in an hour.”
Raj P.
Indie Developer
“We used to spend stand-ups clarifying bug reports. Now they land in the dashboard with the CSS selector, page URL, and browser info. Our average time-to-fix dropped from 2 days to 4 hours.”
Lena M.
Engineering Lead, SaaS Startup
“The AI clustering is what sold me. 12 reports about the same checkout button got grouped into one issue automatically. I didn't have to read each one — I just fixed it.”
