Snap4City is an official platform of FIWARE which you can use for free. It’s open-source and doesn’t require any licenses so that it can be integrated into your business without any hassle. You can also install the platform by using Dockers and/or Virtual Machine Appliances that you find at https://www.snap4city.org/471.
Snap4City uses FIWARE and the NGSI protocol for IoT and is compliant with a large number of protocols, more than 50. https://www.snap4city.org/drupal/node/65
Snap4City also produces several FIWARE NGSI devices: Snap4All IoT Button, Snap4City Arduino IOT device, IOT Edge Snap4City, LoraWAN Gateway IoT Edge, etc.
Snap4City provides many open-source tools that are not FIWARE registered and can be used with FIWARE devices.
Snap4City has produced a mutual authentication model and secure communication compliant with NGSI and IOT Orion Broker.
You will find the details about compliance/interoperability on https://www.snap4city.org/drupal/node/283.

Snap4City started since Km4City former tool. A number of partners and companies have developed tools and processes. All those that have been accepted in the platform and are Open Source are posted on the GITHUB/DISIT, so that you can contribute directly on GITHUB or contacting us as you like.
The main partners are those of Snap4City: UNIFI, UNIMI and Snap SRL, Effective Knowledge, plus also former partners of Sii-Mobility for some aspects of Km4City. The whole activity is coordinated by DISIT Lab, a not for profit research lab (which is in place since 1994) of the University of Florence which is in place since 1300.
The rules for contributing to Snap4City are very simple. One can contribute with:
a new tool and the new tool can be integrated if it respects rules regarding: quality of the code, usability, interoperability with the rest of the platform, security, GDPR compliance, scalability, robustness, documentation in terms of test cases, responsiveness, etc.
You can propose a tool as External Service and in that case the requirements are strongly relaxed. Tools providing functionalities which are already present in other tools of the resent version can be also accepted.
New functionalities improving the present tools, for example starting from the source code on GitHUB and working on the source code. The improved version and new features can be proposed by posting them on Github as branches and presenting them via email email@example.com with a short document, slide and the possibility of testing them from some place.
Bug solving can proposed by proposed by posting them on Github as branches and presenting them via email firstname.lastname@example.org with a short note on the bug solved.
Dashboards, iot Applications, ETL, data analytics, etc. can be freely proposed and shared on both GITBHUB/DISIT and Resource Manager.
There are several cities in a trial/deploy modality, at different stages, the most of them with a new Organisation activated inside the platform: Florence, Tuscany (several cities, including Prato with two pilots, and Pisa), Lonato Del Garda, Sardinia (including the Cagliari metropolitan area), Helsinki, Antwerpen, Modena, Santiago de Compostela, etc. (20-10-2019).
You may register each user to only one Organisation at a time.
The registration is moderated since the private data of the Organisations can be there, and they may adopt different policies for data access and user registration. On the other hand, you can also register using DISIT Organisation to see the tools working on open data regarding Tuscany (many cities such as Firenze, Pisa, Lucca, Massa, Prato, Pistoia, Arezzo, Grosseto, Massa, etc.)
There are also on-premise IoT installations at several companies.

Snap4City sustains itself by selling services over the platform.
The platform is a commodity, and services are:
Consultancy on setting up the smart city, data discovery and aggregation, data identification, living lab set up and management, data agreement, GDPR, etc.
Consultancy on technical aspects of the infrastructure design for the smart city, technical integration with the legacy solution, etc.
customization of the platform with new modules and plugins that, as a rule, will be released open-source (with possible exceptions)
customization of the platform with changes on the code that will be released open-source according to the license model of the tool
smart city as a service (see also EOSC marketplace): hosting data, providing services, etc., with the integration of all the above points
on-premise or cloud installation of the platform
maintenance of an installed Snap4City solution: on our cloud; on any other cloud; on-premise
Training operative personnel to use the platform, create dashboards, IoT Applications, install the platform, etc. This action can be personalized or cumulated in training days and weeks with other customers: it can be on our location or at your premises.
Extra help desk support on all the above aspects that exceed the onboarding already included.
Developing data analytics over those that are freely provided and/or setting up data analytics that needs learning phases at your premises.
Snap4City mobile Apps, web app, and MicroApplications have support in different languages: German, French, Italian, English, Finnish, Spanish.
English is the prevalent language on the development side (user interface, training, and technical documentation).

For problem reporting:
Registration on Snap4City is free. Each user may be registered/login to only one Organisation at a time. You may try multiple registrations to different Organizations using different email addresses and multiple logins.
The registration at the Organization may be moderated since the Organization may load private data and tools and may thus autonomously decide the policies to data access and registration.
We suggest, as a test, registering for Snap4City by selecting DISIT Organization to get access to the tools working on open data for several Tuscany public organizations (among them, cities such as Florence, Pisa, Lucca, Massa, Prato, Pistoia, Arezzo, Grosseto, Massa).
Snap4City is 100% open source.
The table with licenses and the links to access the source code on GITHUB is accessible from https://www.snap4city.org/drupal/node/7.
