See exactly where people click.
Pixel Click Tracker records clicks, taps, scrolls and more at 1-pixel resolution, then turns them into heatmaps you can pull from a simple REST API — no cookies, no vendor lock-in, self-hostable.
Built for teams who need real click data
Not sampled, not estimated — every click is recorded at the exact coordinate it happened.
Per-pixel accuracy
Clicks are stored as exact (x, y) coordinates — no bucketing, no fixed grid unless you ask for one.
Lightweight SDK
A single dependency-free script. Buffers events and flushes on an interval or on page unload via sendBeacon.
Simple REST API
Ingest events with one POST endpoint and pull aggregated heatmaps with one GET — JSON in, JSON out.
Framework-agnostic
Static HTML, React, WordPress — anything that can render a <script> tag can embed the tracker.
Self-hostable
Run it on your own infrastructure with Postgres as the store — your click data never leaves your servers.
Open source
The backend, SDK, and this site are all in one repo — read the code, fork it, self-host it.
Page-to-page flow
See how visitors move between pages with the User Flow report — built from an anonymous per-tab session id, not a cookie.
Three steps from embed to heatmap
Embed one script tag
Add the tracker to any page with a data-site-id attribute. No account or API key required to get started.
We capture interactions
Clicks, taps, scrolls, mouse movement, and focus/blur events are buffered client-side and flushed automatically.
Query your heatmap
Call the heatmap API for any page and render it yourself, or use the built-in Heatmap Viewer.
