The short version

  • Only Hookdeck has a free tier, so it costs nothing to try first.
  • Each has a real cost: Hookdeck pricing meters delivered events, so fan-out multiplies the bill: one inbound event routed to four services counts as four deliveries.; Lambda no free tier or trial, requiring immediate commitment for testing
  • They diverge on capability: Hookdeck covers Ingest and persist, Lambda covers Superclusters.
  • Prices and features above were last checked on 31 August 2026.

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.

Lambda

  • No free tier or trial, requiring immediate commitment for testing
  • Single-tenant Superclusters require custom pricing discussions
  • Pricing complexity across multiple GPU types and cluster sizes
  • Less suitable for experimentation or small teams with tight budgets

Questions people ask

Is Hookdeck or Lambda better?
Neither clearly leads. Hookdeck starts at Free and Lambda at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Hookdeck or Lambda?
Hookdeck has a free tier; the other does not. Paid plans start at Free for Hookdeck and On request for Lambda.
Does Hookdeck or Lambda run on more platforms?
Hookdeck runs on Web, Linux, macOS, Windows. Lambda runs on Cloud.
Can I use Hookdeck for free?
Yes. Hookdeck has a free tier, so you can try it without paying. Lambda starts at On request.
What is Hookdeck best used for?
Hookdeck is most often used for a payments integration where losing a stripe event during a deploy causes an order to go unfulfilled, fanning one provider webhook out to several internal services without each subscribing separately, debugging a partner integration by replaying the exact failing payload after shipping a fix, receiving production-shaped webhooks on a developer laptop without running a public tunnel. Of those, a payments integration where losing a stripe event during a deploy causes an order to go unfulfilled and fanning one provider webhook out to several internal services without each subscribing separately are not what Lambda is typically brought in for.
What can Hookdeck do that Lambda cannot?
Hookdeck covers Ingest and persist, Automatic retries, Filters and fan-out, Transformations. Lambda covers Superclusters, 1-Click Clusters, On-demand instances, Liquid cooling.

Answered from the vendors’ own pages

Hookdeck: Is there a free plan?

Yes, ten thousand events a month with three-day retention and one user.

Lambda: What makes Lambda's infrastructure different?

Lambda offers single-tenant Superclusters with exclusive GPU access, liquid cooling, and NVIDIA Quantum-2 InfiniBand networking. The company is 100% focused on AI infrastructure with co-engineering support from teams who built infrastructure for major AI labs.

Source
Hookdeck: How is usage counted?

By delivered events, so a single inbound webhook fanned out to three destinations counts as three.

Lambda: How does pricing work for large clusters?

1-Click Clusters pricing ranges from $5.54-$9.86 per GPU/hour depending on GPU type and cluster size, with volume discounts for 256+ GPUs. Reserved capacity is available at custom pricing for 1-year+ commitments.

Source
Hookdeck: Can I replay a failed webhook?

Yes, individually or in bulk from the console, with the original payload.

Lambda: Which GPU types are available?

Lambda offers NVIDIA B200, H100, A100, and Tesla V100 GPUs. Individual instances range from V100 at $0.79/hour to B200 SXM6 at $6.69/hour. Newer models like Vera Rubin are available in Superclusters.

Source
Hookdeck: Does it work for outbound webhooks too?

Yes, the same queueing, retry and observability applies to webhooks you send.
