CRED has open source Propeller, its real-time communication platform designed to optimize communication between mobile apps and backend services.
“We initially built Propeller to optimize the UPI payment flow, where every millisecond matters,” said Swami Sitharaman at CRED. “Traditional polling approaches mean we either overwhelm our servers with requests or keep users waiting unnecessarily.”
Propeller has transformed the way CRED members engage with the app, providing 95% faster updates for UPI transactions and instant notifications for rewards, cashback, and CRED win reward confirmations, the company said in a statement.
“Our new architecture built on gRPC bi-directional streaming enables transaction status updates to be almost instantaneous, which is important for members who have come to expect frictionless experiences from CRED,” added Sitharaman.
The platform ensures that members receive immediate feedback for successful or failed transactions, significantly reducing processing delays and increasing user confidence in digital payments.
India ranks second globally when it comes to open source contributions, according to GitHub, a developer platform owned by Microsoft.
Open source refers to software or any other type of work whose source code or design is made publicly available so that it can be modified and redistributed.
Such projects attract developers from all over the world, bringing different perspectives, skills and experiences to the table. A large pool of contributors can significantly speed up development, leading to faster bug fixes, new features, and improved performance.
Sometimes companies open source their projects to attract skilled developers and engineers interested in the technology rather than monetizing them. By contributing to the open source pool, companies can showcase their technical expertise and attract top talent.
