Knock alternatives
Providers that compete with Knock on at least one of: Notifications
Notification infrastructure with workflow engine.
Switching as early-stage startups
At an early stage the deciding factors are what the free tier actually covers, what the first paid invoice looks like, and how much of a founding engineer's week the setup costs. Feature depth that only matters at a million sends a month is noise until it is not.
Knock does not cover operating track record, and none of the alternatives below close that gap either. If it is a hard requirement, the shortlist has to widen beyond this category.
