Clavis
The digital city rally for municipalities

You get to know a city on foot.

Teams walk from station to station and solve tasks on the spot, guided by a coordinator. Clavis is open source, accessible and runs on your own server.

For municipalities that bring people together

Integration work

Newcomers get to know their city by exploring it themselves. In teams, at their own pace, in their own language.

Education and youth work

School classes, holiday programmes, welcome classes. You maintain stations and tasks yourself, and no technical knowledge is needed for that.

City marketing and culture

Museums, monuments, local history. Every station carries its own tasks, and they are solved on site.

How a rally works

  1. Create the content

    A rally is made of stations with a place on the map and the tasks to solve there. Multilingual, if you want it.

  2. Start the run

    The coordinator starts the run and shares a join code. Anyone taking part joins with it, without an account and without an install.

  3. Out and about

    Teams work through the stations and submit their answers. If a team needs help, it pulls the coordinator into its chat.

  4. Score and close

    The coordinator scores as submissions come in and the leaderboard updates at once. At the end there is a result and anonymous feedback.

Three roles, one rally

Taking part

Phone out, code in, off you go.

Out and about, on a phone, often three people around one screen. So the view shows one thing at a time and needs no explaining.

Coordination

Every team in view, without chasing them.

One person at a laptop while twenty people walk the city. Everything they need is on one screen.

Editing

Place stations, write tasks, publish.

The work happens beforehand, at a desk, usually by someone without a technical background. So the editor looks like a form and not like a tool.

The rally editor: title and description of the rally, below it the list of stations with tasks, points and estimated duration.

What Clavis can do

  • Tasks in several forms

    Written, photographed or redeemed on the spot. Whatever can be scored automatically is scored automatically.

  • Joining without installing

    A link or a short code is enough. No account, no app store.

  • Multilingual

    Every organisation decides which languages its content appears in.

  • Guided while it runs

    Coordination reaches every team or just one. Whoever gets stuck gets help.

  • Results without rework

    Scoring happens as you go. At the end the result is there, with nobody adding it up.

  • Built accessible

    Keyboard, screen reader, contrast. The accessibility statement sets out what holds.

  • Data-sparing

    No location history, no data with third parties, fixed deletion periods.

To the roadmap · Everything in detail in the handbook

Runs on your server. Belongs to you.

Clavis is open source under the EUPL-1.2. You run it on a server of your own, or somebody runs it for you.

Common questions

Everything else is in the handbook.

What does Clavis cost?

The software costs nothing. It is licensed under the EUPL-1.2 and may be used, changed and passed on. Costs arise only for your own server and your own working time.

Who operates the software for us?

You do, or your IT provider. Clavis runs as a Docker stack on a server of your own. There is no vendor in between with access to your data.

What data is stored, and for how long?

Team names, answers and scores of a run. No location history, because there is no GPS tracking. Personal data is deleted automatically on fixed deadlines, and the deadlines are in the handbook.

Can several rallies run at the same time?

Yes. One organisation can run several rallies in parallel. Participants only ever see the run they joined.

Ready for the first rally in your city?

We will say honestly whether Clavis fits what you have in mind.
