linkerd vs seneca: What are the differences?

Developers describe linkerd as "Twitter-Style Operability for Microservices". linkerd is an out-of-process network stack for microservices. It functions as a transparent RPC proxy, handling everything needed to make inter-service RPC safe and sane--including load-balancing, service discovery, instrumentation, and routing. On the other hand, seneca is detailed as "A Micro-Services toolkit for Node.js". Seneca is a toolkit for organizing the business logic of your app. You can break down your app into "stuff that happens", rather than focusing on data models or managing dependencies.

linkerd and seneca can be categorized as "Microservices" tools.

Some of the features offered by linkerd are:

• Adaptive load-balancing
• Fine-grained instrumentation
• Abstractions over service discovery

On the other hand, seneca provides the following key features:

• pattern matching: a wonderfully flexible way to handle business requirements
• transport independence: how messages get to the right server is not something you should have to worry about
• maturity: 5 years in production (before we called it micro-services), but was once taken out by lightning

linkerd and seneca are both open source tools. It seems that linkerd with 5.01K GitHub stars and 501 forks on GitHub has more adoption than seneca with 3 GitHub stars and 1 GitHub forks.
