SignalServer was created for companies with different business models, including teams working with traffic acquisition and large portfolios of mobile applications.
We do not create unnecessary onboarding bureaucracy or ask questions that are irrelevant to providing push infrastructure.
We care about technical compatibility, infrastructure requirements, and reliable delivery, not about forcing every customer into the same business model.
Different businesses need the same reliable infrastructure.
