Questions & Answers

As answered by people managing SignalDB and Diffyn.

What's the story behind your product?

SignalDB's answer

The creator of SignalDB, Max Nowack, was inspired by his past experiences working with Meteor.js, which offered a seamless developer experience, particularly in handling real-time data synchronization and reactivity. Over time, as he explored other frameworks and tools like Apollo/GraphQL, FeathersJS, Firebase, Appwrite, Supabase, and RxDB, he found that none of them matched the Developer Experience of Minimongo and Meteor on the frontend side. The discovery of signals in SolidJS led him to grasp its connection to the reactivity he had previously worked with in Meteor, which eventually inspired the creation of SignalDB to bring Meteor-like reactivity to modern JavaScript frameworks.
