Envoy vs Trailblazer: What are the differences?
Developers describe Envoy as "C++ front/service proxy". Originally built at Lyft, Envoy is a high performance C++ distributed proxy designed for single services and applications, as well as a communication bus and “universal data plane” designed for large microservice “service mesh” architectures. On the other hand, Trailblazer is detailed as "A new architecture for Rails". Trailblazer is a thin layer on top of Rails. It gently enforces encapsulation, an intuitive code structure and gives you an object-oriented architecture. In a nutshell: Trailblazer makes you write logicless models that purely act as data objects, don't contain callbacks, nested attributes, validations or domain logic. It removes bulky controllers and strong_parameters by supplying additional layers to hold that code and completely replaces helpers.
Envoy can be classified as a tool in the "Load Balancer / Reverse Proxy" category, while Trailblazer is grouped under "Frameworks (Full Stack)".
Envoy and Trailblazer are both open source tools. Envoy with 10.5K GitHub stars and 1.64K forks on GitHub appears to be more popular than Trailblazer with 2.92K GitHub stars and 131 GitHub forks.
According to the StackShare community, Envoy has a broader approval, being mentioned in 23 company stacks & 29 developers stacks; compared to Trailblazer, which is listed in 3 company stacks and 11 developer stacks.
