For more information on extending the Spryker SDK by implementing the interfaces defined in these contracts please refer to Installation ------------ [](#installation) Usually, installation is not necessary on project level as the dependencies using this will have it as a dependency in their "require" section. But you can install it using Composer as follows: ``` composer require spryker-sdk/sdk-contracts ``` ### Health Score 33 — LowBetter than 74% of packages Maintenance30 Infrequent updates — may be unmaintained Popularity24 Limited adoption so far Community21 Small or concentrated contributor base Maturity51 Maturing project, gaining track record Bus Factor3 3 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window. **Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores. **Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement. **Maturity (30%)** — Project age, version count, PHP version support, and release stability. ### Release Activity Cadence Every ~67 days Recently: every ~108 days Total 12 Last Release 856d ago PHP version history (4 changes)0.1.0PHP >= 8.0 0.2.0PHP >= 7.4 0.4.0PHP >=7.4 0.5.0PHP >=8.0 ### Community Maintainers ![](https://avatars.githubusercontent.com/u/10738957?v=4)[Spryker Bot](/maintainers/spryker-bot)[@spryker-bot](https://github.com/spryker-bot) --- Top Contributors [![vol4onok](https://avatars.githubusercontent.com/u/5063777?v=4)](https://github.com/vol4onok "vol4onok (44 commits)")[![sergeyspryker](https://avatars.githubusercontent.com/u/100715007?v=4)](https://github.com/sergeyspryker "sergeyspryker (28 commits)")[![Kyrylo-Meretskyi](https://avatars.githubusercontent.com/u/86324025?v=4)](https://github.com/Kyrylo-Meretskyi "Kyrylo-Meretskyi (22 commits)")[![pavelmaksimov25](https://avatars.githubusercontent.com/u/82393959?v=4)](https://github.com/pavelmaksimov25 "pavelmaksimov25 (20 commits)")[![newLoki](https://avatars.githubusercontent.com/u/461574?v=4)](https://github.com/newLoki "newLoki (16 commits)")[![dereuromark](https://avatars.githubusercontent.com/u/39854?v=4)](https://github.com/dereuromark "dereuromark (7 commits)")[![miroshnikov-logema](https://avatars.githubusercontent.com/u/90911422?v=4)](https://github.com/miroshnikov-logema "miroshnikov-logema (5 commits)")[![DmytroKlymanSpryker](https://avatars.githubusercontent.com/u/111562890?v=4)](https://github.com/DmytroKlymanSpryker "DmytroKlymanSpryker (3 commits)")[![miroshnikov-spryker](https://avatars.githubusercontent.com/u/94458630?v=4)](https://github.com/miroshnikov-spryker "miroshnikov-spryker (1 commits)")[![spryker-release-bot](https://avatars.githubusercontent.com/u/26904324?v=4)](https://github.com/spryker-release-bot "spryker-release-bot (1 commits)") ### Code Quality Static AnalysisPHPStan Type Coverage Yes ### Embed Badge ![Health badge](/badges/spryker-sdk-sdk-contracts/health.svg) ``` [![Health](https://phpackages.com/badges/spryker-sdk-sdk-contracts/health.svg)](https://phpackages.com/packages/spryker-sdk-sdk-contracts) ``` ### Alternatives [phpdocumentor/type-resolver A PSR-5 based resolver of Class names, Types and Structural Element Names 9.2k719.5M166](/packages/phpdocumentor-type-resolver)[pimple/pimple Pimple, a simple Dependency Injection Container 2.7k130.5M1.4k](/packages/pimple-pimple)[league/container A fast and intuitive dependency injection container. 86387.8M342](/packages/league-container)[stella-maris/clock A pre-release of the proposed PSR-20 Clock-Interface 7947.5M2](/packages/stella-maris-clock)[wptrt/wpthemereview PHP\_CodeSniffer rules (sniffs) to verify theme compliance with the rules for theme hosting on wordpress.org 217736.5k29](/packages/wptrt-wpthemereview)[inpsyde/modularity Modular PSR-11 implementation for WordPress plugins, themes or libraries. 54383.3k3](/packages/inpsyde-modularity) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
