Devise vs Elasticsearch: What are the differences?
Developers describe Devise as "Flexible authentication solution for Rails with Warden". Devise is a flexible authentication solution for Rails based on Warden. On the other hand, Elasticsearch is detailed as "Open Source, Distributed, RESTful Search Engine". Elasticsearch is a distributed, RESTful search and analytics engine capable of storing data and searching it in near real time. Elasticsearch, Kibana, Beats and Logstash are the Elastic Stack (sometimes called the ELK Stack).
Devise can be classified as a tool in the "User Management and Authentication" category, while Elasticsearch is grouped under "Search as a Service".
Some of the features offered by Devise are:
- Is Rack based
- Is a complete MVC solution based on Rails engines
- Allows you to have multiple models signed in at the same time
On the other hand, Elasticsearch provides the following key features:
- Distributed and Highly Available Search Engine.
- Multi Tenant with Multi Types.
- Various set of APIs including RESTful
"Reliable" is the primary reason why developers consider Devise over the competitors, whereas "Powerful api" was stated as the key factor in picking Elasticsearch.
Devise and Elasticsearch are both open source tools. It seems that Elasticsearch with 42.4K GitHub stars and 14.2K forks on GitHub has more adoption than Devise with 20K GitHub stars and 4.76K GitHub forks.
Uber Technologies, Instacart, and Slack are some of the popular companies that use Elasticsearch, whereas Devise is used by StackShare, Accenture, and Movielala. Elasticsearch has a broader approval, being mentioned in 2001 company stacks & 976 developers stacks; compared to Devise, which is listed in 56 company stacks and 30 developer stacks.
