Your website has a story.

Tarsier watches it.

Traffic changes. Pages slow down. Things break. Tarsier keeps watch, notices what matters, and tells you when something needs attention.

Traffic jumped. Mostly from Google.

Tarsier dashboard comparing the last day with the day before. Yesterday is the dashed line.
google.com Site Health Report Card, an A plus, with a note from Pica.Site Health Report Cards for one hundred sites, with the top of the class listed beside the count.

The public dashboard, compared with yesterday. Open it. Uptime, speed, and a security look share that screen, and a report card grades the site itself. See the grades. Our site is public. Yours stays private.

Before Tarsier

You should not need four tools for four questions.

Every site owner asks the same four things. Most end up paying four companies to answer them.

Is anyone here?

Visitors, pages, sources, and how that changed since yesterday. One place, not a second login.

Who is showing up, and where they came from.

Pages

The ones people love. And the ones written for nobody.

Campaigns

Which links actually bring people through the door.

Events

Signups, downloads, the button nobody clicks.

Trends

Today against yesterday, without a research project.

Is the site working?

A peek every five minutes, with a month of proof, beside the traffic. Down alerts when it is not.

Is it getting slower?

Once a day, our own browser times the page. The score sits next to uptime, and again on a report card.

Did anything matter?

A week of ordinary days first. Then a note on the chart, and once a week a short letter. A quiet Sunday stays quiet.

Pica noticedSample

Traffic jumped 64% yesterday.

Most of the increase came from Google.

Gets to know you

A week of ordinary days. Then a jump means something.

Notes on the dashboard

A line on the chart, and on the page that caused it.

A weekly letter

Once a week, a short note. A door back to the numbers.

Pica · text message · sample

Hey. You should probably see this.

The homepage was down for 4 minutes. It is back.

When the site goes down, or the traffic jumps, this is the message she sends.

How it works

Three steps. Then it watches.

No tag manager, no consent banner, no second afternoon.

  1. 01

    Add a site

    Name it in Settings. That is the account.

  2. 02

    Paste one script

    One tag in the head. No cookies, nothing to configure.

  3. 03

    See the first visitor

    Probably you. That is okay. We do not judge.

Questions

Before you install it.

Anything else, write to pica@usetarsier.com.

How much does Tarsier cost?

$11.11 a month, or $111 for the year. The year is two months free. Same features either way.

What do I get?

100,000 pageviews a month, across every site, and 50 sites. Uptime, a daily check, a security look, report cards, and Pica's Notes are included. Not a smaller product if you pay monthly.

Can this notify me if my site is down?

Yes. For a site you ask us to watch, Pica can reach you by email, text, or both when it goes down, or when traffic jumps or falls hard.

Does this replace my analytics provider?

It can. It can also sit beside the one you already have, and be the little guardian for the site itself.

How often does it check uptime?

Every five minutes. You get a status and a run of bars, not a second dashboard to babysit.

What is the daily check?

A Site Speed Analysis, timed by our own browser instead of Google, and a brief look at the page itself. Scripts, frames, redirects, and the Tarsier Threat Index. The same checks can be read as a report card. Not a promise the server is clean, and not every visitor's phone.

Need more sites or pageviews?

Write to pica@usetarsier.com. The listed price is 50 sites and 100,000 pageviews. Higher room is the same product, priced with you.

Does it use cookies?

No. Watching a website should not mean following its visitors around the internet.

What are Pica's Notes?

Pica gets to know the site first. Then her notes show up on the dashboard. Once a week she writes a short letter. Urgent news, like downtime, is separate from that letter.
