Workflows vs events
Knock is built around workflows — visual pipelines that define how notifications flow, batch, delay, and branch. It's powerful for complex notification logic.
Sendivent is built around events. You emit an event, we route it to channels. Less powerful, but simpler.
The price difference
Knock's entry price is $250/month. Sendivent has a free tier and lower paid tiers.
For early-stage products, that difference matters. You might not need workflow complexity yet.
When workflows matter
Complex notification logic benefits from Knock's approach:
- Batching multiple events into digests
- Conditional branching based on user preferences
- Sophisticated delay and scheduling
When simplicity wins
For straightforward notification needs:
- User signs up → send welcome email
- Order ships → send SMS + email
- Team invite → send Slack + email
A simpler model is faster to implement and maintain.
Bottom line
Knock is for teams who need sophisticated notification workflows. Sendivent is for teams who want to ship notifications quickly without the workflow overhead.
