Snap4City - scalable Smart aNalytic APplication builder for sentient Cities

  CLICK for NEWS  Smart Cities need to set up a flexible Living Lab to cope with the city evolution in terms of services and city users’ needs and sustainability. Snap4City solution  ( provides a flexible method and solution to quickly create a large range of smart city applications exploiting heterogeneous data and enabling services for stakeholders by IOT/IOE, data analytics and big data technologies. Snap4City applications may exploit multiple paradigms as data driven, stream and batch processing, putting co-creation tools in the hands of: (i) Smart Living Lab users and developers a plethora of solutions to develop applications without vendor lock-in nor technology lock-in, (ii) final users customizable / flexible mobile Apps and tools, (iii) city operators and decision makers specialized / sophisticated city dashboards and IOT/IOE applications for city status monitoring, control and decision support. Snap4City satisfies all the expected requirements of Select4Cities challenge PCP and much more, and it is 100% open source, scalable, robust, respects user needs and privacy; provides MicroServices and easily replaceable tools; compliant with GDPR; provides a set of tools for knowledge and living lab management, and it is compliant with more than 60 protocols including end-to-end encrypted communication. Snap4City is an official platform of FiWare, an official library of JS Foundation Node-RED, registered on E015, present on EOSC marketplace, and BeeSmartCity MarketPlace, etc.  


Snap4City improves city services, security and safety by offering a sustainable solution for smart city and Living Lab, thus attracting industries and stakeholders. Snap4City is capable to keep under control the real time city evolution: reading sensors; computing and controlling key performance indicators, KPI; detecting unexpected evolutions; performing analytics; taking actions on strategies and alarms. Snap4City supports the city in the process of continuous innovation on services, infrastructures, with control and supervision, tools for business intelligence, predictions, anomaly detection, early warning, risk assessment, whatif analysis, also setting up strategies for increasing city resilience with respect to unexpected unknown events. Thanks to knowledge base support, Snap4City provides flexible solutions to get immediate insights and deductions of the city status and evolution, exploiting ultimate artificial intelligence, data analytics and big data technologies, activating sentient solutions collecting, and exploiting heterogeneous data of any kind, from any data source (open and private; static, real time, event driven, streams, certified and personal). Please perform a free registration. if you are interested on testing by selecting "DISIT" as preferred organization, on which you can find a large number of data accessible. Snap4City provides services and data of several cities/Organizations as: Firenze, Helsinki, Antwerp, Pisa, Prato, Pistoia, Lucca, Arezzo, Grosseto, Livorno, Siena, Massa, Modena, Cagliari, Venezia, etc.; and from regions as Tuscany, Garda Lake, Sardegna, Belgium, Finland, Emilia Romagna, etc. Snap4City is open to your contributions, using Snap4City tools and contributing in improving them, adding more tools and features, etc. Please join the community on this portal and on GitHub/disit

Snap4City is 100% open source, secure encrypted, scalable, modular and flexible, managed by DISIT Lab of University of Florence, in collaboration with other institutions and companies accepting to work on open source model; it can be used to set up Living Lab and smart city solutions satisfying a large range of requirements of city officers, citizens, and tourists to developers, companies and researchers. It can be easily integrated with in place solutions to provide from data, factors and causes, predictions, anomalies, optimizing resources and understanding social contexts and meanings of facts from data. It can be installed on cloud and on premise. This capability is obtained by enforcing the new functionalities of Snap4City tools/modules on your premise and/or exploiting them from cloud. Snap4City is based on Km4City knowledge base and smart city API, a suite of open source technologies for developing smart cities big data aggregators and analytics adopted in TRAFAIR CEF, REPLICATE EC H2020, RESOLUTE EC H2020, Sii-Mobility SCN MIUR, WEEE Life, Green Impact, 5G with Wind 3G and Estra, MOSAIC, SmartBed, SODA, and others. Snap4City added to Km4City the flexibility to set up Living Labs and co-working environments for IOT/IOE (internet of things/everything) in smart cities and industry 4.0; to use a large range of IOT devices, IOT Edge, IOT Buttons, IOT Gateways, PAXCounters, mobiles, OBU (on board unit, vehicular kit for bikes, cars and busses), social media and satellite data, and it is open to all standards and custom models. Some of these devices are also produced by Snap4City as Open hardware and Open Software.
