Bottom line
OpenTweet is the pick for developers automating X content with API, MCP and feed connectors. PostFast fits creators managing several networks better, and it reaches Instagram and Facebook among others, which OpenTweet doesn't.
A verified price comparison requires the same billing term, currency and eligible workload. See each pricing section for the published terms. PostFast adds a social inbox that OpenTweet leaves out.
