Alpha vs Beta Testing

Alpha testing is done by the developer or tester at the customer site which is mostly like performing usability testing. This is the type of Acceptance testing. This is done to take note of the problems faced by the user. The focus of this testing is to simulate real users by using BlackBox and WhiteBox techniques. It ensures that the user will get high-quality services in the form of complete functionalities and stability. 

Beta testing is done by a limited number of end-users before delivery and the defects reported at this phase would be fixed before the official release. This is also the type of Acceptance testing. The customer provides inputs into the functionality and usability of a product which is important for the success of the product. It also reduces product failure risks and provides increased quality of the product through customer validation. It is the final test before shipping a product to the customers.

Alpha testing is performed at the developer’s site. Alpha testing is performed at the end-user production environment
Reliability and Security Testing are not performed during Alpha Testing   Reliability, Security, Robustness are checked during Beta Testing  
Alpha testing may require a long execution cycle. Beta testing requires only a few weeks of execution.
Developers can immediately address the critical issues or fixes in alpha testing. Most of the issues or feedback collected from beta testing are scoped and implemented in future versions of the product.
Alpha testing requires a lab environment or testing environment Beta testing doesn’t require any lab environment or testing environment.
