Most of us who live in a terminal have something on the go: a tool other people use, or a product we’d like to turn into a business. Both run on knowing who reads what, and where they came from.
Sponsors want numbers. Show them real ones: a public page of your figures, an embed that follows your site’s light or dark, a view count anyone can ask for. Count every click on Sponsor. With hard mode, your banner can ask readers for support in your own words, as eza’s does:
“About 1,500 visits a month read this page”, under eza.rocks’s sponsor card, is a tidekeeper number.
Built it over a weekend? Find out who uses it. Funnels and revenue by source from your first day, on the first plan. Goals, events with their properties, real time. And when a number moves, one sentence says why:
Goals reached, how many finish a funnel, and what moved, on a phone. The sentence above and these figures are examples.
Most analytics is a tab you forget to open. tidekeeper shows the tide of all your sites in your browser, your terminal and Claude, in your pocket, on your wrist and on the TV across the room.

Pictures from the apps, the web and the terminal, and the conversation with Claude, with example sites and figures.
Start with one line on your site and nothing to ask your visitors. When it becomes a business, turn on hard mode. When you hire, bring the team. The same tool the whole way.

Thirty days give a spike time to happen. Nothing is charged before day 31, and cancelling before then costs nothing.
Then €9 a month, VAT included. Without a credit card, counting stops after 14 days, and your figures stay readable for 30 days more.
Launch sale until 30 November.What’s new in tidekeeper, and the day the apps land on Google Play. Your email, nothing else.
A confirmation mail first, then a letter now and then. Leave with one click in any of them. Privacy policyWith a credit card, Tide goes on at €9 a month, VAT included, and cancelling before day 31 costs nothing. Without one, nothing is charged: counting stops after the 14 days, and your figures stay readable for 30 days.
Every view is counted. A spike never stops tidekeeper and never costs extra on its own: only a site that stays over its plan is asked to move up.
In easy mode tidekeeper sets no cookie and keeps nothing on a reader’s device. When you need a banner, tidekeeper is there: hard mode, which needs one in most places, brings a banner in your own words and colours, and lets you see who comes back and what they do across visits.
Yes: from Plausible, Umami, GoatCounter or Matomo. The blog in the chart above came over from Umami, Hacker News day and all.
The counting script is under 2 KB gzipped (1,570 bytes on eza.rocks) and loads with defer, from tidekeeper or from your own domain. In hard mode, the banner that asks adds about 7 KB.
It reads your figures, and changes things only if you let it.
No. We’ve done a lot of open source, eza among it, and seen it taken by others; AI has made that easier. So tidekeeper is closed, and hosted by Point Free ApS in Denmark. What you get instead: every site downloads whole, as a zip of its figures, whenever you want.
Point Free ApS in Denmark: the company of Christina Sørensen, who maintains eza.

P.S. I maintain eza. eza.rocks runs on tidekeeper, and the line under its sponsor card comes from it. If you build something people use, I’d love you to see your own numbers. — Christina
