AWS Kinesis Local Mock

kinesis-local provides a mock API for AWS Kinesis, enabling developers to simulate Kinesis data streams for local testing and development environments without incurring AWS costs or requiring an internet connection. The current stable version is 0.5.2, with releases occurring periodically to address bug fixes, update dependencies, and improve underlying infrastructure. It is primarily built on Scala, with recent significant updates including an an overhaul from Scala 2 to Scala 3 and an upgrade to Node.js 25 for its Docker image, introduced in v0.5.0. This tool differentiates itself by offering a fully functional local Kinesis endpoint, allowing for comprehensive integration testing of applications that interact with Kinesis, including producers (KPL) and consumers (KCL), directly on a developer's machine.
