This is what every seenbase user sees about their visitors.

populated server-side

The card on the right is filled with your own session — the same fields that arrive every time someone opens a tracked file.

Nothing is reconstructed from a profile. There's no profile to reconstruct. Each row is the raw observation a single pixel call produced.

Every pixel you create captures the same fields, from any document or page where you place it.

§ 04 / In practice

How teams use seenbase.

example workflows, not testimonials
Sales / SDR
"I sent a proposal and I have no idea if they read it."

See the open within sixty seconds of it happening — and whether they came back to it later. Multiple opens from different IPs at the same company means the committee is reviewing.

Proposal tracking 101 →
Job seeker / Recruiting
"I'm job hunting. LinkedIn says 'viewed by 4 recruiters' — useless."

See which company opened your CV, when, and whether they passed it to a colleague. Repeat opens from the same network are the signal — one open is noise.

How to track CV opens →
Marketing / EU compliance
"Our marketing team needs GA-style analytics, but legal won't allow cookies in the EU."

Hashed IPs, no cookies on the tracked surface. You still need a lawful basis for your recipients — see the Privacy Policy.

Indie / OSS maintainer
"I want to know if my README badge or Notion page actually gets traffic."

Drop a tracking pixel anywhere an image fits. Free for the first 1,000 opens a month — enough for most side-projects forever.
