validate-pyproject-schema-store
A plugin set for validate-pyproject and schema-store.
Decision gist · record as of 2026-08-14
Yes, if you use validate-pyproject and want stable, pinned schema validation. The low install friction, active maintenance, permissive license, and lack of known vulnerabilities make it a straightforward addition to validation workflows. The limitation on nested schemas is documented and unlikely to affect most pyproject.toml validation use cases.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires validate-pyproject to be installed separately (or use the [all] extra); nested schemas are not yet supported and are replaced with "type": "object".
- Low install friction with a single runtime dependency (fastjsonschema).
- Active maintenance with a release on 2026-08-14 and support for current Python versions (3.9 through 3.15).

What it is and what it does
validate-pyproject-schema-store is a companion package that bundles a versioned snapshot of SchemaStore schemas for use with the validate-pyproject tool. It allows you to pin a stable set of schema files rather than relying on dynamic schema resolution, which is useful for reproducible builds and pre-commit hooks. The package depends on fastjsonschema for schema validation and supports Python 3.9 through 3.15.
The package is designed to work in two modes: as an injected dependency alongside validate-pyproject (useful for pipx or pre-commit workflows), or as a standalone entry point that can be run directly. Nested schemas are not yet supported—they are currently replaced with generic object types—but the package is actively maintained and receives regular updates.
Use it for
- Pin schema versions in pre-commit hooks to ensure consistent validation across team members and CI/CD pipelines.
- Use with pipx to run validate-pyproject without managing a separate Python environment.
- Validate pyproject.toml files in build systems where schema updates should be controlled and versioned.
- Integrate into CI/CD workflows where reproducible schema validation is required.
