It takes flag definitions and rules, then evaluates them against user context to determine which flags are enabled and what configuration values apply. The engine is written in plain Python using Marshmallow schemas for data validation and serialization, making it lightweight and portable.\n\nThis package is the computational heart of Flagsmith's flag resolution logic. Rather than a full feature-flag management platform, it's the evaluation component\u2014useful if you're integrating Flagsmith's flag logic into your own systems or running a custom deployment where you need the flag engine as a library. It depends on jsonpath-rfc9535 for JSONPath queries, semver for version comparisons, and typing-extensions for type hints.","worth_installing":"Yes, if you need Flagsmith's flag evaluation logic as a library component. The low install friction, active maintenance, permissive license, and zero known vulnerabilities make it safe to adopt. However, verify first whether you need the full Flagsmith platform or just this engine\u2014it is a specialized component designed primarily to power the main Flagsmith API rather than a standalone feature-flag client."},"id":"flagsmith-flag-engine","links":{"html":"https://skillfed.io/packages/flagsmith-flag-engine","md":"https://skillfed.io/packages/flagsmith-flag-engine.md","pypi":"https://pypi.org/project/flagsmith-flag-engine/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-06-09","license_spdx":null,"license_treatment":"permissive","name":"flagsmith-flag-engine","python_support":"unspecified","summary":"Flag engine for the Flagsmith API."},"popularity":{"monthly_downloads":1019299,"position":4496,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"10.2.0"}
