  • Only Hookdeck lists ingest and persist; only Linearity Curve lists vector editing.
  • Where Hookdeck falls short: pricing meters delivered events, so fan-out multiplies the bill: one inbound event routed to four services counts as four deliveries.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Hookdeck

  • Pricing meters delivered events, so fan-out multiplies the bill: one inbound event routed to four services counts as four deliveries
  • Free-tier retention is three days, which is shorter than the time it typically takes to notice a failing integration, so the payloads needed for a replay are often already gone
  • It becomes a single point of failure in front of every third-party integration, and an outage there means every provider webhook queues or fails at once
  • The transformation layer runs JavaScript in a constrained environment, so anything that needs a database lookup or an external call has to happen downstream instead
  • For a team already running Kafka or SQS the value is mostly the console and the replay UI, which is a hard cost to justify against infrastructure they already operate

Linearity Curve

  • Limited to Apple ecosystem (Mac, iPad, iPhone) with no Windows or Linux support
  • Requires annual or monthly subscription for commercial use, unlike competitors offering lifetime purchase options
  • Free plan is severely limited to only 3 Curve files and 5GB storage
