The speed test grew a lab bench

The page speed test now reads like a report you would keep. A grade dial, the page weight, the load time, and the request count sit on one navy board. The four vitals each carry a budget: good, needs work, or poor. The phone frame is the page as our browser saw it. The waterfall still times every request on one shared line.

The other free tools share that bench. Same form, same progress, same panels. Pica still gets the last line on every report. She does not round up.

Hack Check now fetches the page as a crawler first, then opens it in a browser, and compares the two. A script only one of them received is cloaking. Contact is now Support. The owner and Pica read every email.

Hack Check cries wolf less, and notices more

A free Hack Check used to call a site worth a closer look whenever it met a script it did not recognize. A custom CDN, a small analytics host, a tag from a tool we had not named: all of that raised the verdict. Those hosts are still listed, and still marked Unknown. They no longer change the answer.

A hop from the bare domain to www, or to a subdomain of the same site, is no longer treated as leaving the site. A hop to a different site is worth a closer look. It is not the same as a malware listing. Flagged stays for a reputation hit or a host on the known-bad list.

The visit now also notices a hidden link that points off the site, a base tag that rewrites the page's links through another host, a packed script built with fromCharCode, and a script loaded from a bare IP or a throwaway ending such as .tk or .zip.

Report cards, comparisons, and the watch on the dashboard

The top 100 websites each have a Site Health Report Card. Four checks, weighted the same: speed, security, reputation, and whether the site lives in a good neighborhood. Pica writes the note. The directory is at /sitehealthcheck, and each card has its own address.

The dashboard opens with Pica's read of the site, then the traffic, then the tables. A compare control sets the range against the previous period, the same day last week, last month, or last year. The change lands on the headline numbers and as a dashed line on the chart. She only writes a note when a number actually moved.

Uptime, speed, and security sit in one panel under that verdict. Uptime keeps the recent peeks. Speed shows the daily score, the paints, and the weight. Security shows what the last look found. Each column opens its free tool with the site already filled in.

Homepage redesign: monitoring-focused positioning

The homepage got a major redesign focused on monitoring and analytics. The HERO section stayed the same, but the dashboard under the headline is now the real product layout, with a link to the live one-click demo. Who this is for (founders, marketers, SEOs, publishers, agencies) sits under the headline before you scroll.

Every visit is still written the way it always was, so nothing already collected moves or disappears. Fields that did not fit get a second copy beside that row, using the same site, session, and counts.

The live dashboard opens on a phone again

The public Tarsier dashboard was showing a loading error for visitors without a session. Its data calls now open for the public demo, while other sites still require sign-in and ownership.

The homepage's little portraits no longer download full-size photos. Inter and Outfit come from our own server. Sharing the homepage or live dashboard now shows a proper preview image.

Cloudflare returns 522 when this Worker asks to check itself from inside the house. That is not a visitor outage. Our own health now says so plainly; while other sites still get real peeks.

Six free tools, one hub

Page Speed Test, Hack Check, Uptime Check, Tracker Check, Built With, and TTFB Check. Each answers a question people actually search for, each is free without an account, and each ends at the same place: put Tarsier on it. They live under Tools, with /tools tying them together.

/monitor rebuilt for 50 sites

The monitor was a mile of cards. Now it is a wide board of compact rows: status, uptime bars, score, speed, security, checked-ago. Search, All/Napping/Needs-a-look filters, and napping-first sorting keep fifty sites manageable. Folders still organize everything.

Site Speed Analysis replaces Lighthouse

Google is out of the loop. Once a day, our own browser opens the page on a phone-sized screen and times it: LCP, FCP, page weight, and whether the page got heavier overnight. The score, the vitals, and the change all live on /monitor and the health strip.

A brief look at the page

Once a day, Pica opens the homepage and a few links. She notices a new script, a hidden frame, a strange redirect, or a host on a short public list. She does not call the site clean. A plugin can look further in, later.

Jev is on the stack

Pica's notes will ask Jev whether a change is worth saying. Jev returns a decision, not a sentence. The name is on the stack now. The full set of notes, the longer list of templates, and the weekly letter come later. She is still getting to know the site.

A watch for the site itself

/monitor is Pica's watch. She peeks at the site, not the visitors. Pictures, when she feels like taking one.

Watch my website starts an account

That button goes to signup. A new account adds a site before the dashboard opens, so there is nothing empty to 404 on.

An account, not only a shared password

Sign up makes an organization. The session carries that org. Sites still belong to the org in KV. The shared operator password still opens the Tarsier account.

A page that is just David

/davidkrug is a link page. No site nav. The letter, Tarsier, the notes, the docs, the changelog, and where to find him.

The measuring engine is Tarsier's

A visit, an event, and a ping are defined in one place. Writes and queries both use that list. The slots did not move, so old rows still count.

One read for the dashboard

The dashboard asks once. The widgets still exist, so paging and the old routes keep working. The nightly extract skips a day it already saved.

Hot memory, then cold

Analytics Engine still answers the last 89 days. A queue folds each pageview into a daily file in R2, so the year does not vanish when the hot window does. Dashboard reads older than today are cached at the edge.

A long note about Cloudflare

How I fell in love with Cloudflare is up. Servers, Workers, and why Tarsier lives where it does.

The code is called Tarsier

Packages are @tarsier. The snippet id is tarsier-script. Older embeds still report. The worker, the public site id, and the stored history stay where they are.

A letter, when there is news

The newsletter page is live. An address is stored. Nothing is sent until there is something worth saying.

A price, said out loud

$11.11 a month, or $111 for the year. 100,000 pageviews and 50 sites. Same product either way. Higher bands wait until they are real.

The person building this

The about page names David Krug. Manila, two kids, one amazing partner, and the build on X. No stock headshot.

A note you can read in four minutes

A field note on the stack. Short on purpose. The links stay on the about page, where a list belongs.

The stack, named

The about page now says what Tarsier is built on, and who helped write it. OpenCode, with Muse 1.3, Grok 4.7, and North Mini Code. No mystery, no fake team page.

The first chapter, said out loud

The about page now says the true thing. Tarsier is at the beginning. The job is already clear: you should not have to become an analytics person.

No invented customer wall. The proof is the live dashboard, and Understand and Tell me stay marked Soon until they exist.

Serious software. Enormous eyes.

The homepage now says who this is for before you scroll: founders, marketers, SEOs, publishers, and agencies. The dashboard under the headline is the real layout, and the live one is one click away.

Every visit is still written the way it always was, so nothing already collected moves or disappears. Fields that did not fit get a second copy beside that row, using the same site, session, and counts.

Stories, a live count, and a globe

The homepage now opens with named tarsiers, a live count of who is here, and a line that says what this is: your website has a story. Tarsier watches it.

The dashboard grew up with it. Our own site is public. Yours is not. The live card is a real rotating earth you can drag, and visitor countries flash coral.

Know where visits start and end

Every session now has a front door and a back door. Entry pages show where visits begin; exit pages show where they leave. Both are computed per session, both are click-to-filter, and both live right under Pages and Referrers where they belong.

The same update adds quick actions to the top of the dashboard — add a site, copy the tracker URL, jump to the live feed — and a Traffic share card that shows where your visitors come from at a glance.

Documentation goes live

Tarsier finally has docs worth linking to: installation, the snippet, and events and goals — written from the actual code, including the parts where the old README disagreed with it.

The footer sitemap grew up alongside: company, resources, and legal columns, with honest Soon badges on anything that does not exist yet.
