paradict
Streamable multi-format serialization
Decision gist · record as of 2026-08-14
Yes, if you need a multi-format dictionary serialization library with schema validation and support for rich datatypes. Install friction is minimal and the MIT license poses no restrictions. However, maintenance is dormant—the last commit was 2024-12-10 and activity is minimal—so consider this for stable, self-contained use cases rather than projects requiring active upstream support.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low friction: pure Python wheel with no runtime dependencies.
- Maintenance is dormant—last commit was 2024-12-10 and the repository has not been archived, but activity is minimal.

What it is and what it does
Paradict is a serialization library that converts Python dictionaries to and from textual or binary representations. It offers two textual modes—a data-mode for bidirectional mapping to binary, and a config-mode with lighter syntax for configuration files—making it a multi-format alternative to JSON, YAML, TOML, Protobuf, MessagePack, and CBOR. The library supports a rich set of datatypes including strings, binary data, integers, floats, complex numbers, booleans, dates, times, datetimes, and nested lists, sets, and dictionaries.
Paradict includes a validation mechanism where schemas describe expected keys and data types, optionally with custom checker callbacks for programmatic validation. The API is built on four fundamental classes—Encoder, Decoder, Packer, and Unpacker—for iterative serialization, plus bulk functions and utilities like pack_into and unpack_from for file I/O. An extension mechanism allows custom object builders to transform extension objects during deserialization.
Use it for
- Serialize application state or configuration to binary files with datetime and complex number support
- Validate incoming dictionary data against a schema before processing
- Read and write structured data files in a human-readable textual format with lighter syntax than JSON
- Stream large dictionaries incrementally using Encoder and Decoder classes
- Define custom types and objects that deserialize into domain-specific Python classes via object builders
