Most "best video hosting" lists are written for someone else. They rank Vimeo and Wistia for everyone and move on. That is fine if you are building a portfolio. It is the wrong advice if you buy cold traffic and send it to a video sales letter, because neither of those tools is built to score a split test on sales or fire a watch-depth pixel back to your ad account. For direct response, that is the whole game.
VSLBench looks at the same tools through a direct-response lens. We read what long-term users report on Reddit, Hacker News and review sites, we read each vendor's own docs and pricing, and we check the numbers that decide your return: whether a player can measure how many viewers start, how many hold to the pitch, and how many of those actually buy. Then we say plainly which tool wins, which loses, and who each one is wrong for.
