What abtest is
abtest is a web service for testing YouTube thumbnails and YouTube titles. It uses a freemium model with a free Hobby plan and paid access from $10 a month. Hobby allows three tests at a time, limits each test to one week, and keeps a history of ten tests. The Personal plan costs $10 a month when billed monthly and supports ten tests at a time, with a maximum duration of two weeks. The service is available on the web. Its listed testing scope covers YouTube thumbnail tests and YouTube title tests. abtest does not provide server-side testing, a mobile SDK, audience targeting, or feature flags. These plan limits make the service primarily about managing concurrent YouTube experiments and their allowed durations, with test-history details specified for Hobby.
