A high-performance Swift framework for serializing and deserializing model objects to/from JSON, designed for REST APIs.
Serpent is a Swift framework for serializing and deserializing model objects (structs and classes) to and from JSON. It provides a protocol-based approach to handle encoding and decoding, supporting complex data types like nested objects, enums, URLs, and dates. It solves the problem of tedious boilerplate code when consuming REST APIs by offering high-performance parsing and seamless Alamofire integration.
iOS, macOS, tvOS, and watchOS developers building apps that consume REST APIs and need efficient JSON mapping for model objects. It's particularly useful for teams prioritizing performance and reduced boilerplate.
Developers choose Serpent for its exceptional parsing speed, comprehensive type support, and tight Alamofire integration. Its compatibility with the Model Boiler app drastically reduces manual coding, making model creation quick and error-free.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Benchmarks show up to 4x faster JSON decoding than similar libraries, ideal for performance-critical apps handling large payloads.
Out-of-the-box parsing for enums, URLs, Dates, UIColor, and nested objects reduces custom code, as demonstrated in the School/Student example.
Includes responseSerializable extension for one-liner API calls that auto-parse responses into models, streamlining network layer code.
Integration with Model Boiler app auto-generates boilerplate serialization code, cutting model creation time significantly.
The repository is archived with no future updates, risking compatibility with newer Swift versions, iOS releases, and security patches.
Each model requires explicit encodableRepresentation and init methods, adding complexity even with Model Boiler, unlike Swift's native Codable.
Relies on Objective-C's NSDictionary for serialization, which is less Swift-idiomatic and may introduce bridging performance overhead.
Best features depend on Nodes' tools like Model Boiler and Cashier, creating vendor dependency that complicates switching.
