Capistrano is an open-source remote server automation and deployment tool that is primarily used for deploying web applications to remote servers. It automates the process of code deployment, configuration updates, and other tasks related to managing web applications on remote servers.

Key features of Capistrano include:

1. Automated Deployment: Capistrano automates the deployment process by allowing users to define deployment tasks and workflows in a configuration file.

2. Version Control Integration: Capistrano integrates with version control systems like Git and Subversion to fetch and deploy specific versions of code from repositories.

3. Multi-Stage Deployment: Capistrano supports multiple deployment stages, such as development, testing, and production. This allows users to deploy to different environments with customized configurations.

4. Rollbacks: Capistrano provides the ability to rollback to a previous deployment version in case of issues, ensuring that the application can be quickly restored to a known working state.

5. Task Execution: Users can define custom tasks to perform various actions during deployment, such as migrating databases, clearing caches, or restarting services.

6. Parallel Execution: Capistrano can execute tasks in parallel on multiple servers, speeding up the deployment process for large applications.

7. Configuration Management: Capistrano allows users to manage server configurations and environment variables as part of the deployment process.

8. Plugin System: Capistrano has a plugin system that allows users to extend its functionality by adding custom tasks and features.

9. Community and Ecosystem: Capistrano has an active community that contributes to its development, provides support, and shares best practices for deployment automation.

Capistrano is especially popular among Ruby on Rails developers, as it was initially designed for deploying Rails applications. However, it can also be used to deploy other types of web applications and services. Capistrano simplifies the process of deploying code changes to remote servers, making it a valuable tool for maintaining and updating web applications in a controlled and automated manner.
