## What it is
SBJson is an Objective-C framework providing a strict JSON parser and generator with stream/chunk-based operation. It lets you parse JSON incrementally, calling a block per root-level document or array entry as data arrives.

## Use cases
- parse JSON incrementally as it downloads over a slow connection
- parse very large JSON documents without loading them fully into memory
- generate JSON from Objective-C objects
- process a stream of multiple JSON documents
- strict JSON parsing in iOS or macOS apps

## When to choose
- you are developing in Objective-C for Apple platforms and need streaming/chunked JSON parsing
- you need to parse huge JSON files with low memory usage
- you want to reduce perceived latency by parsing before a download completes

## When to avoid
- you are using Swift and prefer native JSONSerialization or Codable
- you need actively developed software with frequent updates
- you need non-strict or lenient JSON parsing

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, serialization
- domain: parsers, developer-tools, mobile-development
- platform: cross-platform
- tags: objective-c, streaming-parser, chunk-based, carthage, cocoa, ios, macos
