Gem Comparison

We reviewed many other gems and we encourage you to check them out to see if they meet your needs better than Chamber does. Here are our candidates:

Here are the breakdowns of their features. Hover over any item for a more detailed explanation.

Note on Namespaces: When you see the word "namespaces" in the table below, and you've never used Chamber before, you may be a little confused. It simply means a way of segregating the same settings keys between different use cases. The most common of these is environment. For example your API key for Stripe may be one thing in test and another thing in production.

All other settings libraries focus on the environment. While this is the most common, there are other use cases such as a namespace for CI or a namespace for a dev's local computer. In Chamber these are first class citizens. So while the libraries below may get a checkmark for a namespace row, know that Chamber's namespacing is much more powerful.

Comparison Matrix

I've made every attempt to be as accurate as possible. If I'm incorrect on any of these, please let me know via an issue.
