Why Pack Tester?

Pack Tester is an efficient binary serialization format that's faster and smaller than JSON. But testing Pack Tester APIs can be challenging without the right tools.

Pack Tester bridges this gap by providing a modern, user-friendly interface for encoding, decoding, and testing Pack Tester-based APIs. Whether you're debugging production issues or developing new endpoints, our tool makes the process seamless.

Built with Next.js and modern web technologies, it runs entirely in your browser with no server-side dependencies. Your data stays private and secure.

// Example: Encode data to Pack Tester
const data = {
name: "John Doe",
age: 30,
active: true
}
const encoded = msgpack.encode(data)
// Binary data ready for API request
