Knock Pricing (2026)

Knock charges based on messages sent — a pure usage-based model where you're paying for notification volume, not seats. Notably, bounced or failed messages don't count toward billable usage, which is a developer-friendly touch that reduces billing anxiety.

AI Pricing Analysis

Pricing Model

Tier Strategy

The free Developer tier is clearly a sandbox for individual devs or early-stage products getting notification infrastructure off the ground. Teams hit the ceiling when they need production-scale volume, SLA guarantees, or compliance requirements — that's when $250/mo Starter or a custom Enterprise deal becomes the conversation.

Competitive Positioning

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.

Growth Lever

HIPAA compliance is hard-walled behind Enterprise, which is a smart forcing function for any healthtech customer. Beyond compliance, expansion is driven by raw message volume — as a product's user base grows, so does the bill, making this a natural land-and-expand play tied directly to customer success.
