beta
BAY-tuh
/ˈbeɪtə/
A pre-release version of software distributed to a limited group of external users for real-world testing.
Beta software is mostly complete and functional, but it is expected to have bugs. It is the final testing phase before the software is released to the general public.
The story behind the word. In the mid-20th century, IBM pioneered a testing sequence. 'Alpha' was the first phase of internal testing. 'Beta' was the second phase, where the software was sent to external clients to see how it performed in the wild.
Word relationships
- trial version: A trial version is often a fully finished product with a time limit, whereas a beta is an unfinished product undergoing active testing.
- stable release: A stable release is the final, fully tested version of software made available to all users.
Commonly confused with
- alpha: Alpha testing is done in-house by developers, while beta testing involves external users in real-world environments.
Word family
- tester (noun): A person who tests beta software.
Collocations
- beta test
- beta version

Example sentences

Memory hook
Beta is the 'B' version—the second step after the 'A' (Alpha) version. B is for Beta, the second phase of testing.
When not to use
Do not use beta to describe the very first, highly unstable draft of a program; that is the 'alpha' phase.
Fun facts
- Gmail famously stayed in 'Beta' status for over five years, from 2004 to 2009, despite having millions of active users.
