Open Source Serverless Projects
Serverless is a cloud computing model in which a provider manages the underlying servers and runs application code on demand. Workloads often respond to events, such as web requests, scheduled tasks, or messages, and scale automatically as demand changes. This can reduce infrastructure management and costs for intermittent workloads, while introducing considerations such as execution limits, cold starts, and dependence on provider-specific services.
Open source tools in this area include deployment frameworks, runtime platforms, local emulators, and services for routing events or managing data. When choosing one, consider its maturity, license, maintenance activity, runtime and infrastructure requirements, integrations, observability, and portability. These tools can help developers and operations teams build, test, and run event-driven applications, whether they are adopting managed cloud infrastructure or seeking more control over deployment.
