“Being a small team Kuzzle plays an important role in our stack. It has allowed us to focus on developing our clients’ business logic. The permission system, search capabilities and extendability has helped us keep both our mobile apps and websites backends simple.
To get up and running quickly I recommend hiring the Kuzzle team for training. It gave us what we needed to build our first proof-of-concept in a week.”
