PLAIN PYTHON · ZERO RUNTIME DEPS
Choosing a Python validator
A task-based choice between small dict validation and broader validation tools.
Choose by the boundary you need
Zodify 0.6.0 is a fit for small plain-Python dict shapes, zero required runtime dependencies, and an explicit exact-type default. Its limited typing and interoperability surface is a tradeoff.
Pydantic v2 TypeAdapter validates types without requiring a BaseModel subclass and provides serialization and JSON Schema generation. Consider it when those capabilities or Pydantic-compatible types matter. A model class is not required for every Pydantic task.
For standards-based JSON Schema validation, choose an implementation of the required draft. For a tiny CLI, argparse alone may be enough. Compare your own accepted and rejected inputs before comparing timing.
No universal speed ranking
This is a capability selection guide, not a timed library comparison. Zodify examples are checked against the installed 0.6.0 wheel. Pydantic capability statements refer to its current v2 documentation, checked September 9, 2026; no competitor timing is claimed.
There are no invented adoption figures, maintenance rankings, or framework affiliations here.
