Github Actions vs Heroku CI: What are the differences?

1. Integration with platform: GitHub Actions is tightly integrated with GitHub repositories, allowing seamless automation of workflows within the same ecosystem. On the other hand, Heroku CI is specifically designed for continuous integration and deployment on the Heroku platform, providing native support for deploying applications to Heroku.

2. Pricing: GitHub Actions offers a generous free tier for public repositories and limited usage on private repositories, with additional costs based on usage beyond the limits. In comparison, Heroku CI is an addon service provided by Heroku, with pricing based on the number of test runs and parallel test instances required.

3. Scalability: GitHub Actions provides scalable workflows that can be easily customized and managed for projects of any size, with the ability to run parallel jobs concurrently. Heroku CI, being a platform-specific tool, is more limited in scalability compared to GitHub Actions.

4. Customizability: GitHub Actions allows for extensive customization using YAML-based configuration files, offering flexibility in defining workflows, triggers, and actions. Heroku CI, while providing some customization options, may be more restrictive in terms of configuration compared to GitHub Actions.

5. Environment support: GitHub Actions supports a wide range of operating systems, programming languages, and tools, allowing developers to build and test applications in diverse environments. In contrast, Heroku CI is primarily focused on supporting applications deployed on the Heroku platform, which may limit the scope of environments that can be tested.

6. Deployment capabilities: While both GitHub Actions and Heroku CI enable continuous integration and deployment workflows, GitHub Actions can be used to deploy applications to various platforms beyond just Heroku, providing more flexibility in deployment options compared to Heroku CI.

In Summary, GitHub Actions and Heroku CI differ in terms of platform integration, pricing, scalability, customizability, environment support, and deployment capabilities.
