Which one is cheaper?: Courier is the cheaper option, starting at $0/mo vs $250/mo for Knock.
Can I use either one for free?: Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.
How do they charge?: Both use a usage-based model, so the comparison is straightforward — it comes down to features and limits at each price point.
Which one is a better deal?: Depends on what you need. Knock: At $250/mo for Starter, Knock is positioning itself as a serious infrastructure layer — not a budget tool, but not absurdly expensive for what it replaces (building in-house notification systems). They're going after product teams at growth-stage companies who've outgrown DIY but aren't ready to negotiate six-figure contracts. Courier: Half a cent per send is a low-friction entry point designed to undercut the complexity of competitors like Twilio or Iterable that layer on channel costs and seat fees. They're going after dev-led teams who want predictable, simple pricing without a sales call.
