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 ~46 days Recently: every ~83 days Total 55 Last Release 54d ago Major Versions v2.5.1 → v3.0.12022-03-13 v1.1.13 → v2.5.22022-05-30 v2.5.2 → v3.0.22022-05-30 v2.5.3 → 3.2.x-dev2023-04-27 v2.5.4 → v3.4.32024-09-25 PHP version history (7 changes)v1.1.1PHP ^7.1.3 v2.0.0PHP ^7.2.9 v2.0.1PHP ^7.2.5 v2.1.2PHP >=7.2.5 v1.1.9PHP >=7.1.3 v3.0.0PHP >=8.0.2 v3.1.0PHP >=8.1 ### Community Maintainers ![](https://avatars.githubusercontent.com/u/47313?v=4)[Fabien Potencier](/maintainers/fabpot)[@fabpot](https://github.com/fabpot) --- Top Contributors [![nicolas-grekas](https://avatars.githubusercontent.com/u/243674?v=4)](https://github.com/nicolas-grekas "nicolas-grekas (89 commits)")[![fabpot](https://avatars.githubusercontent.com/u/47313?v=4)](https://github.com/fabpot "fabpot (31 commits)")[![derrabus](https://avatars.githubusercontent.com/u/1506493?v=4)](https://github.com/derrabus "derrabus (23 commits)")[![kbond](https://avatars.githubusercontent.com/u/127811?v=4)](https://github.com/kbond "kbond (9 commits)")[![xabbuh](https://avatars.githubusercontent.com/u/1957048?v=4)](https://github.com/xabbuh "xabbuh (5 commits)")[![chalasr](https://avatars.githubusercontent.com/u/7502063?v=4)](https://github.com/chalasr "chalasr (2 commits)")[![StevenRenaux](https://avatars.githubusercontent.com/u/59167761?v=4)](https://github.com/StevenRenaux "StevenRenaux (2 commits)")[![andersonamuller](https://avatars.githubusercontent.com/u/1681800?v=4)](https://github.com/andersonamuller "andersonamuller (2 commits)")[![lyrixx](https://avatars.githubusercontent.com/u/408368?v=4)](https://github.com/lyrixx "lyrixx (2 commits)")[![mbessolov](https://avatars.githubusercontent.com/u/2725121?v=4)](https://github.com/mbessolov "mbessolov (1 commits)")[![Neirda24](https://avatars.githubusercontent.com/u/7036794?v=4)](https://github.com/Neirda24 "Neirda24 (1 commits)")[![Nyholm](https://avatars.githubusercontent.com/u/1275206?v=4)](https://github.com/Nyholm "Nyholm (1 commits)")[![OskarStark](https://avatars.githubusercontent.com/u/995707?v=4)](https://github.com/OskarStark "OskarStark (1 commits)")[![reedy](https://avatars.githubusercontent.com/u/67615?v=4)](https://github.com/reedy "reedy (1 commits)")[![rosier](https://avatars.githubusercontent.com/u/117380?v=4)](https://github.com/rosier "rosier (1 commits)")[![stof](https://avatars.githubusercontent.com/u/439401?v=4)](https://github.com/stof "stof (1 commits)")[![thewilkybarkid](https://avatars.githubusercontent.com/u/1784740?v=4)](https://github.com/thewilkybarkid "thewilkybarkid (1 commits)")[![ValentineBoineau](https://avatars.githubusercontent.com/u/34517639?v=4)](https://github.com/ValentineBoineau "ValentineBoineau (1 commits)")[![wouterj](https://avatars.githubusercontent.com/u/749025?v=4)](https://github.com/wouterj "wouterj (1 commits)")[![mateuszsip](https://avatars.githubusercontent.com/u/1377075?v=4)](https://github.com/mateuszsip "mateuszsip (1 commits)") --- Tags contractphpservicesymfonysymfony-contractstandardsinterfacesinteroperabilitycontractsabstractionsdecoupling ### Embed Badge ![Health badge](/badges/symfony-service-contracts/health.svg) ``` [![Health](https://phpackages.com/badges/symfony-service-contracts/health.svg)](https://phpackages.com/packages/symfony-service-contracts) ``` ### Alternatives [symfony/event-dispatcher-contracts Generic abstractions related to dispatching event 3.4k756.5M424](/packages/symfony-event-dispatcher-contracts)[symfony/contracts A set of abstractions extracted out of the Symfony components 3.9k64.6M103](/packages/symfony-contracts)[symfony/translation-contracts Generic abstractions related to translation 2.6k698.7M432](/packages/symfony-translation-contracts)[symfony/cache-contracts Generic abstractions related to caching 2.4k308.9M198](/packages/symfony-cache-contracts)[symfony/http-client-contracts Generic abstractions related to HTTP clients 2.0k402.7M267](/packages/symfony-http-client-contracts) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
