Bebop is a high-performance data interchange format designed for fast serialization and deserialization.

// Example Bebop Schema
struct Person {
  string name;
  uint32 age;
// Generated TypeScript Code
new Person({
    name: "Spike Spiegel",
    age: 27
Write concise and expressive schemas with Bebop's intuitive syntax. Using a generated class to persist data.
