AtalaiaYour servers, from the corner of your screen.
A small watchtower that keeps an eye on the servers you care about — and only speaks up when one of them is really down.
Everything answering: a dot, a name, the last few minutes and the latency.
The window
Every server in one list: its state, its last few minutes and its latency. Each dot answers as its check comes back.
It does not cry wolf
- A dropped check is not an outage. It turns the server amber and brings the next check forward. Nothing is raised.
- An outage has to last. Down means failing for the whole confirmation window — 30 seconds by default — on several checks in a row.
- Is it them, or is it you? When nothing answers, Atalaia first asks whether your own connection is up, and never blames your servers for it.
- Coming back takes two answers. A server that flaps does not flood you with down-and-back notifications.
What it checks
What it refuses to do
- Nothing to install on your servers. Every check is made from your machine, the way you would make it yourself.
- No history on disk, no telemetry. The last day lives in memory for the charts, and nothing is sent anywhere. A report goes only when you write one and send it.
- No dashboard. A glance at a corner of the screen, not one more window to keep open.
Questions
How does it know my own connection dropped?
When a server fails and no other server has answered since, Atalaia asks two
well-known addresses — 1.1.1.1 and 8.8.8.8, on port 443 —
whether this machine can reach the internet at all. If it cannot, the overlay says
your connection is down, your servers are held rather than blamed, and every clock
starts again when the connection returns.
Waking from sleep gets the same courtesy: failures in the first seconds after the lid opens never count.
Why only the Microsoft Store?
Because there Microsoft signs Atalaia, and Windows trusts what Microsoft signed at once. Offered as a download from this page, the same program was unsigned, and Windows' SmartScreen and now and then an antivirus warned about it, as they warn about any new program nobody has signed. For a watchtower, a false alarm costs the trust it lives on.
The Store also installs Atalaia and brings its updates; Atalaia looks for none itself. A copy installed from this page before keeps working and no longer updates itself: install Atalaia from the Store, and it offers to take the old copy out, keeping your servers.
Does Atalaia send anything anywhere?
No telemetry, no analytics, no account, no logs on disk. Atalaia contacts two kinds of address: your own servers, as you configured them; and the two reference addresses above, only while a server is failing with nothing else answering — a TCP handshake and nothing more. It never looks for a newer version of itself: a copy from the Microsoft Store is updated by the Store.
Report…, in About, sends a problem or an idea to whoever makes Atalaia, and only when you press Send, having seen all that goes: what you wrote, the version and, unless you switch them off, the Windows version and a few facts about this Atalaia, such as its language and how many servers of each kind it watches. What Atalaia adds never includes a server's name or address, a path or a file.
A webhook posts to a Slack or Discord channel only if you add one, and only to the address you pasted: an outage or a return of the servers you point there, Atalaia starting and stopping, and a test when you ask. Each message says which server, what failed and for how long; its address and latency go only if you switch them on.
How do I move the overlay, or change its order?
The overlay ignores the mouse so it can sit over anything. Choose Unlock to move in the tray menu, drag it anywhere on any screen, and press Lock on it. It remembers the nearest corner, so a longer list grows away from the edge you put it against.
The order is the list in Atalaia's window: drag a server up or down there, and the overlay and the tray menu follow.
Can I copy my server list to another machine?
Everything lives in one readable JSON file, and About says where it is. Copy it across, or generate it — hand edits are welcome while Atalaia is closed, and anything out of range is brought back into it.
Which systems and languages are supported?
Windows 10 and 11, x64. TCP, ping and HTTP checks, from every 5 seconds to every 5 minutes.
English, Português, Español, Deutsch, Français, Italiano, Polski, Русский, 中文, 日本語 and 한국어, following your Windows display language, with a choice in the preferences. Linux is next: the monitoring core already runs there.
Atalaia is free. If it has earned its corner of your screen, a donation helps keep it that way.
