Any ideas for a Solidarity City App?


With I startet a web application to find places where you can participate in city life without papers and / or money.

The most fruitflully database is of course OSM. At the moment the following tags are processed:

Camping and caravan site with no fees: ["tourism"~"caravan_site|camping_site"][fee=no]
Drinking water: [amenity=drinking_water]
Fitness stations: [leisure=fitness_station]
Librarys: [amenity=library]
Parks: [leisure=park]
Showers: [amenity=shower]
Toilets: [amenity=toilets]
WLAN Access Points: [amenity=shower]

I am thinking about the following other tags:
Food: [“social_facility”~“soup_kitchen|food_bank”]
Goods: [“amenity”=“public_bookcase”]
Goods: [“social_facility”=“clothing_bank”]

Any other ideas are welcome!

Please feel free to use the derived WMS services (daily) under the usual conditions (CC-BY-SA (C) OpenStreetMap-Contributors) :

The following other “Databases” are used:
Other ideas?

If you like to contribute please get in contact, there is an editor available to map places which do not fit into the other databases.

Hello Martin

Thanks for this inspiring map. It makes me happy to see that others have a similar focus.

Maybe the Suspended Coffee Concept is interessing for you. You can find a source with many places at this website I don’t know if they have an open api.

An other project is for free sharing of household items. I also don’t know if they have an open api.

I created a map that shows free facility and offers based on OSM data:
Over the info button (i) you can find the OSM tags and the overpass query I use. Perhaps there is something that matches your focus.

Best regards,


Interesting concept. I’m quite irritated by the overlay when clicking a POI. Don’t make it fullscreen and make it a least a bit transparent, because now it punches you in your face.

Another thing i noted “Translated by google” - not a big fan of that, but i understand it might be easy to use. Why not translating it manually via strings and with contributions? Transifex or or something like that? :slight_smile:

Thanks for your work!

Hi Markus,
Thanks a lot for the inspiring links, especially for your great priceless application. There are a lot of amazing project out there in the sense of a Solidarity City (predominant on a local level). I tried to do a link collection here and added your project:
Best regards,

Hi Negreheb,
„Don’t make it fullscreen and make it a least a bit transparent“
The webapplication is yet only optimized for mobiles, I will put this on the TODO list.
Manually translations are possible with the editor. If you like to contribute please send me a PM for an account. Translations are also possible for languages which are not supported by Google, e.g. Central Kurdish (Sorani) – ckb and Southern Kurdish (Pehlewani)- sdh.
Best regards,

This is very cool! But now I don’t know if I should use or, or which one to recommend to others. Shouldn’t you work together? :slight_smile:

Sorry for the late reply. But I do not see any competition between the web applications, as the focus is quite different. I like & use priceless a lot, and it is definitely the better choice for viewing OSM data. The focus of the SolidaryCityMap is more on „events“, like medical care for free & all. But unfortunately there is not so much input from the communities at the moment.

Thanks a lot for your input! Now the following data is now integrated: - suspend or get o coffee (or whatever on the menu) - a sharing community
OSM Food:
• [amenity=baking_oven]
• [amenity=bbq]
• [amenity=food_sharing]
• [social_facility=food_bank]
• [social_facility=soup_kitchen]
• [social_facility=food_sharing]
OSM Goods:
• [amenity=bicycle_repair_station]
• [amenity=compressed_air]
• [amenity=give_box]
• [amenity=device_charging_station]
• [amenity=toy_library][fee=no]
• [amenity=public_bookcase]
• [amenity=charging_station][fee=no][parking:fee!=yes][authentication:none=yes]
• [amenity=piano][!shop]
• [musical_instrument=piano][!shop]
• [musical_instrument:piano=yes][!shop]
• [repair=assisted_self_service]
• [social_facility=clothing_bank]
• [shop=charity][payment:none=yes]
• [shop][charity=yes][payment:none=yes]
• [shop=second_hand][payment:none=yes]
• [shop][second_hand=yes][payment:none=yes]
• [shop=charity][fee=no]
• [shop][charity=yes][fee=no]
• [shop=second_hand][fee=no]
• [shop][second_hand=yes][fee=no]

Other ideas for datasets are welcome!
