1. Version Control System Integration: Capistrano primarily integrates with Git for version control, while Shipit supports a wider range of version control systems such as Git, Mercurial, and others.

2. Configuration Language: Capistrano uses Ruby for configuration, making it more flexible but also potentially more complex for non-Ruby developers. Shipit, on the other hand, uses YAML which is simpler and more universally understood.

3. Parallel Deployment: Capistrano deploys sequentially by default, meaning it handles deployments one at a time. Shipit, however, offers the option for parallel deployment, allowing multiple tasks to be executed simultaneously.

4. Plugin Ecosystem: Capistrano has a more extensive plugin ecosystem compared to Shipit, providing a wider variety of extensions and integrations with other tools and services.

5. Error Handling: Capistrano provides more robust error handling capabilities, including the ability to rollback deployments in case of failures. Shipit, while capable of handling errors, may not have as advanced rollback features.

6. Community Support: Capistrano has been around for longer and has a larger and more established community compared to Shipit. This can result in better documentation, support, and resources available for Capistrano users.

In Summary, Capistrano and Shipit differ in their version control system integration, configuration language, parallel deployment capabilities, plugin ecosystem, error handling, and community support.
