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.

Bug reports without context are just noise
Same bug, two very different outcomes
Without blocFeed
“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”
Result: No screenshot. No selector. No browser info. Can't reproduce.
With blocFeed
Find bugs users report — and the ones they don't
Element-level bug capture, session replays, and passive behavioral detection. One platform for explicit feedback and silent UX issues.
Click any element to report
Users click the broken element, describe the issue, and submit an annotated screenshot with CSS selector, page URL, and viewport context.
AI triage and issue clustering
Every report is categorized, prioritized, and clustered into issues and themes. Spot spiking trends without reading every entry.
Session replays with AI summary
Connect PostHog to link every feedback item to its session replay. AI summarizes what the user did, where they struggled, and what broke.
Behavioral signals, zero effort
Rage clicks, dead clicks, JS errors, and form abandonment — detected passively. Correlated with feedback to surface issues nobody reported.
Slack, Linear, Jira & PostHog
Spike alerts and weekly UX digests in Slack. One-click issue creation in Linear or Jira, pre-filled with full context.
One package, two minutes
A lightweight NPM package. No iframes, no browser extension, no performance overhead. Behavioral tracking runs passively in the background.

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.”
