CoffeeScript vs. Hubot vs. JavaScript vs. Riemann Comparison Chart

Hubot is your friendly robot sidekick. Install him in your company to dramatically improve employee efficiency. Today's version of Hubot is open source, written in CoffeeScript on Node.js, and easily deployed on platforms like Heroku. More importantly, Hubot is a standardized way to share scripts between everyone's robots. We ship Hubot with a small group of core scripts: things like posting images, translating languages, and integrating with Google Maps. We also maintain a repository of community Hubot scripts and an organization of community Hubot packages that you can add to your own robot. The real fun happens when you add your own scripts. Be sure to personalize your Hubot, too; your company's robot should be a place full of inside jokes, custom integrations, and general merriment.

Riemann aggregates events from your servers and applications with a powerful stream processing language. Send an email for every exception in your app. Track the latency distribution of your web app. See the top processes on any host, by memory and CPU. Combine statistics from every Riak node in your cluster and forward them to Graphite. Track user activity from second to second. Riemann provides a low-latency, transient shared state for systems with many moving parts. Riemann streams are just functions that accept an event. Since Riemann's configuration is a Clojure program, its syntax is concise, regular, and extendable. Configuration-as-code minimizes boilerplate and gives you the flexibility to adapt to complex situations. Riemann can tell you as much or as little as you want. Throttle or roll up multiple events into a single message. Get emails about exceptions in your code, provider downtime, or latency spikes. You can also integrate with PagerDuty for SMS or phone alerts.
