Composer vs Hyperledger Fabric: What are the differences?
Developers describe Composer as "Dependency Manager for PHP". Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you. On the other hand, Hyperledger Fabric is detailed as "An open source initiative to advance blockchain technology". It is a collaborative effort created to advance blockchain technology by identifying and addressing important features and currently missing requirements. It leverages container technology to host smart contracts called โchaincodeโ that comprise the application logic of the system.
Composer and Hyperledger Fabric are primarily classified as "Package Managers" and "Blockchain" tools respectively.
Composer and Hyperledger Fabric are both open source tools. It seems that Composer with 20.5K GitHub stars and 5.56K forks on GitHub has more adoption than Hyperledger Fabric with 8.62K GitHub stars and 4.9K GitHub forks.
Walls.io, Zumba, and Infoshare are some of the popular companies that use Composer, whereas Hyperledger Fabric is used by FairVentures, Figure, and IntellectEU. Composer has a broader approval, being mentioned in 138 company stacks & 246 developers stacks; compared to Hyperledger Fabric, which is listed in 9 company stacks and 9 developer stacks.
