If you want to test an idea, create a proof of concept (POC) or a minimum value product (MVP), or even start a project, then Hyperledger Composer can help you do so quickly and easily. You can test your business network with a web application named Composer Playground. With some clicks and a good use case, you can also create a business networking integrated into your systems. Another option is to create a frontend application to use your smart contract.
