In general, questions that are a search request or asking for a product recommendation are off-topic almost everywhere on the Stack Exchange network.
The basic principle behind search requests is that we're here to provide our expertise, not help you find that expertise somewhere else.
Product recommendation questions are off-topic because they are highly-opinionated and attract spam answers.
