Bytery is a schema-aware binary serialization format and reference library designed to replace JSON in transport and storage scenarios.

It aims to make structured payloads smaller and faster to encode and decode by combining:

• compact binary primitive encodings
• string table reuse
• date table reuse
• schema table reuse
• optional outer GZIP compression

Bytery Viewer

Below is a real Bytery payload being inspected by the built-in viewer.

The screenshot shows the full wire structure in a human-readable way: original JSON preview, optional headers, colorized hex dump, string table, date table, schema table, and the decoded data tree. This makes it much easier to debug the binary format and verify exactly how each value is represented on the wire.

In this example, the payload includes optional headers such as author and when, but headers are not required by the format.

Repository Purpose

This repository contains two related deliverables:

• the Bytery protocol specification
• the reference implementation and supporting experiments

Project Status

• Protocol status: draft v1.1
• Reference implementation: VB.NET
• Secondary implementation artifacts: TypeScript
• Compatibility note: the specification is stabilizing and may still receive clarifications before a first public stable release

Documentation

• Specification: docs/spec.md
• Full examples: docs/full-examples.md
• Benchmarks: docs/benchmarks.md
• Protocol status: docs/protocol-status.md
• Roadmap: docs/roadmap.md
• Browser example: examples/json-roundtrip.html

Quick Start

Primary implementation paths in the current repository:

• Bytery
• Test
• implementations/typescript

Published documentation paths:

• docs/spec.md
• examples/json-roundtrip.html

Design Goals

• Smaller payloads than plain JSON
• Faster encode and decode for repeated structured data
• Deterministic binary wire format
• Clear separation between protocol and implementation
• Friendly to future multi-language implementations

Publishing Guidance

If you are arriving from GitHub:

1. Read the protocol first in docs/spec.md.
2. Review the VB.NET implementation in Bytery/.
3. Review the TypeScript implementation artifacts in implementations/typescript/.
4. Use CONTRIBUTING.md before opening pull requests.
