Wikipedia, Khan Academy, CK-12 and science simulations, reachable from any phone or laptop in the school with no internet at all: one small server makes it happen, and carries the school platform and the backups too.
What it costs, roughly: a complete seat from about €184 with a reused screen, the whole-school server about €319, a full 25-computer lab about €9,000. The software is free and open source. Plan it for your school →
Every KUBO lab runs on one server. It serves the offline library and tools to every seat, and backs up critical data to the cloud whenever there is a connection, even a weak one. It starts on a Raspberry Pi and scales up to whatever hardware a school's needs call for.
The offline lessons, reference libraries and classroom tools run from the server to every seat, so a class never waits on the internet.
When a connection is available, the server syncs critical data to the cloud, so the things that matter stay safe and recoverable.
Begin with a single Raspberry Pi. As needs grow, move the server to bigger hardware, and nothing else in the lab has to change.
A library most schools with internet would envy, fully offline and reachable from any device with WiFi: the lab's desktops, a laptop, a tablet, a phone. Straight in the browser, nothing to install. Your school picks what fills its server:

children's booksServed by the two leading open-source projects for offline learning:
Kolibri, Learning Equality's offline learning platform, integrated with our school platform's Learn module.
Kiwix, which puts entire reference libraries offline, from Wikipedia to Project Gutenberg.
The world map builds on OpenStreetMap. Logos and content belong to their respective projects.
The server comes with the KUBO school platform pre-configured, just a click to activate. It is the software that runs the whole school: grades, term reports, timetables, attendance and health records, with a login for everyone, from the head teacher to each student.

The server is designed around one assumption: the connection is the exception, not the rule. Everything a school needs on a normal day runs locally, and the rare moments of connectivity are used well.
Lessons, the library and the school platform run on the school's own network, reachable from any device with WiFi and a browser. Nobody at school notices whether the internet is up.
When a connection appears, the server syncs grades, reports and records to the cloud, then carries on alone. The library itself needs no backup, because it can always be filled again.
The first server draws just a few watts, small enough to run from solar. When the school's needs grow, it moves to stronger hardware and the rest of the lab keeps working unchanged.
Every lab joins our private zero-trust overlay network: nothing stands open to the internet, each machine sees only what it needs, and we can reach the devices we care for. Over that line travel updates, the record backups and a heartbeat with the server's health, and when something misbehaves we debug it remotely. The machines stay yours: open source, full access for your own team, and running entirely without us stays possible.
The IT Lab, Offline Server and School Platform each work on their own and are strongest together. Here are the other two parts.
