Nippy is a fast, mature serialization library for Clojure, serving as a high-performance drop-in alternative to the Clojure reader for freezing and thawing data. It supports all standard Clojure data types, optional LZ4/Zstandard compression, AES128 encryption, and extension to custom types.

Use cases

• serialize clojure data structures to bytes for storage
• fast serialization for caching clojure values in redis
• compress and encrypt clojure data before writing to a database
• replace slow clojure reader-based serialization
• persist long-lived clojure data with forward compatibility
• serialize custom clojure types

When to choose

• you need high-performance serialization of Clojure data at scale
• you want optional compression and encryption built into serialization
• you need guaranteed readability of serialized data across future versions
• you're building on libraries like Carmine, XTDB, or Datalevin

When to avoid

• you need language-agnostic serialization like JSON or protobuf
• you're not working in Clojure or on the JVM
• you need human-readable data formats
