We are Neighbourhoodie Software, and we specialise in web technology consulting and application development.

We're a group of experienced web technology experts with a strong focus on the human side of software. We can help your company or project with our knowledge and skills, either hands-on with code or in consultation workshops. We're especially versed in the design and implementation of Offline First web apps, package management and release automation with npm, as well as all aspects of CouchDB.

“We recently built a new product with Neighbourhoodie Software. They did a fantastic job and are an amazing team to work with.”

The Company

Together, we know a lot about web technologies, from compelling user experience design and frontend development to the intricacies of distributed databases. Let us help you plan, kickstart, build or even salvage your projects.

Our Expertise

Our core passions are Offline First, noBackend and CouchDB, but we’re also versed in rapid prototyping and working on Open Source projects:

Offline First

We think web apps should just work, whether you’re connected to the internet or not. We can advise on architecture and app design, as well as the novel challenges of designing offline-capable web apps.


Our company manages and develops the Open Source project Hoodie, a new, more human-friendly approach to building web apps. This has provided us with an incredible amount of experience in designing client libraries, server and database setups, testing, release management, API design and community work.


Apache CouchDB is the database that syncs, and we’re using it to power Hoodie. Jan, our CEO, has been a core developer since 2007, and provides unrivalled expertise. We offer a wide range of professional services related to CouchDB.

Rapid Prototyping

Hoodie, our Open Source web app development stack, not only simplifies work, but also accelerates it. Together with our experience with modern frontend frameworks such as Ember, Riot, amd React(Native), we can build functional software prototypes for you in record time.

Open Source Development

As maintainers of and contributors to several large Open Source projects, we can safely say that we know our way around. Do you depend on a package that needs work, or would like to Open Source some of your own software, for your own benefit as well as that of the public? We can help you with all of that.

Release automation and Dependency Management

Running our own products and releasing our own Open Source modules has led us to optimising and automating these processes to a high degree, culminating in the semantic-release, an Open Source tool for fully automated package publishing, as well as Greenkeeper, our service for managing npm dependencies. If you need help in either of these fields, we’re the ones to ask.

We’d love to work with you, so please don’t hesitate to contact us!

The Hoodie Open Source Project

Hoodie The Hoodie Open Source Project

Project Scope: Our team comprises the inventors of Hoodie and members of its core community. Hoodie is a web server that provides user authentication, data persistence and offline-sync out of the box, and can easily be extended using plugins. Its front-end friendly APIs empower User Experience Designers & Developers to build entire applications, without being limited by backend constraints. Hoodie pioneered Offline-First design principles on the web. We designed and built the project while fostering an Open Source community that now helps to drive the project forward.

Past Projects

Our past clients range from very small companies over medium-sized agencies to big NGOs, all of them with high standards and requirements. And don’t worry if you’re not based in Berlin, like us: we’re well versed in working with remote clients, also across different time zones and cultural backgrounds.

Avalanche Barrier Maintenance Application

Client: pitsch-ing.ch engineering, Switzerland Avalanche Barrier Maintenance Application

Project Scope: In order to support a national initiative to transition the avalanche barrier maintenance in the Swiss Alps away from paper-based maps, we developed a prototype for digital map support which would help the barrier maintenance teams improve their work. The prototype includes offline maps and a digitalised version of all avalanche barriers. Maintainers can add photos and comments to each barrier while doing their checkup, data is being synchronised back to the server as soon as their devices are back online.

Ebola Response: Consulting

Client: eHealth Africa, Nigeria Ebola Response: Consulting

Project Scope: In 2014, our team joined the African-American NGO eHealth Africa that is working with West African governments, as well as international organisations like WHO, UNICEF, CDC and various other NGOs, on the response to the Ebola outbreak. We worked on various applications based on AngularJS, PouchDB and Apache CouchDB. These apps were used in call centers, for contact tracing, nutrition surveys, biometric registration and reporting systems in Liberia, Guinea, Somalia, Sierra Leone, Mali and Madagascar. All apps are in full operation in various environments with challenging network connectivity. We were responsible for UI and UX improvements, design and implementation of new features, as well as major performance and security improvements and software rollouts. We also took over project management and team lead and helped grow the team from eight to 27 people.
