It extends standard JSON reference resolution to work with OpenAPI's non-URI relative file paths, which standard JSON reference libraries do not support. The package provides two main parsing modes: ResolvingParser, which follows and resolves all JSON references into a flat specification dictionary, and BaseParser, which parses without resolving references.\n\nThe package includes a command-line interface for validating specs, compiling them into fully resolved output files, and converting older Swagger 2.0 specs to OpenAPI 3.0 format via an external web service. It depends on chardet, ruamel.yaml, requests, and packaging for core functionality, and delegates actual validation to pluggable backends (openapi-spec-validator, swagger-spec-validator, or flex) that you install separately.","worth_installing":"Yes, if you need to parse or validate OpenAPI/Swagger specs in Python. The package is actively maintained, has low install friction, and fills a real gap in reference resolution. Clarify the MITNFA license before use in proprietary contexts. Avoid the flex backend due to deprecated dependencies with known security issues."},"id":"prance","links":{"html":"https://skillfed.io/packages/prance","md":"https://skillfed.io/packages/prance.md","pypi":"https://pypi.org/project/prance/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-19","license_spdx":null,"license_treatment":"unclear","name":"prance","python_support":"supports_current","summary":"Resolving Swagger/OpenAPI 2.0 and 3.0.0 Parser"},"popularity":{"monthly_downloads":6194071,"position":1959,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"26.7.19.0"}
