The short version

  • Each has a real cost: Convoy the default deployment is self-hosted, so you operate Convoy plus Postgres and Redis and carry the on-call burden for the system that delivers your customers' events.; Zeplo zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
  • They diverge on capability: Convoy covers Inbound and outbound, Zeplo covers URL prefix interface.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Convoy

  • A fintech that cannot route customer webhook traffic through a third-party SaaS for compliance reasonsnot Zeplo
  • A high-volume platform for which per-message webhook pricing costs more than the flat premium licencenot Zeplo
  • A team that also receives webhooks from many providers and wants ingestion, verification and deduplication in the same gatewaynot Zeplo
  • An engineering group that wants webhook delivery driven directly from an existing Kafka or SQS topicnot Zeplo

Zeplo

  • A Vercel or Cloudflare Workers application that needs retried background jobs without deploying a separate always-on workernot Convoy
  • A team that wants a webhook receiver protected by a concurrency limit so a burst does not overwhelm a downstream APInot Convoy
  • A small product needing cron jobs against HTTP endpoints without adding a scheduler to its infrastructurenot Convoy
  • A developer adding idempotent retries to an unreliable third-party API call with a one-line URL changenot Convoy

Where each one falls short

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

Convoy

  • The default deployment is self-hosted, so you operate Convoy plus Postgres and Redis and carry the on-call burden for the system that delivers your customers' events.
  • Frain Technologies is a small startup, and putting customer-facing delivery infrastructure on it means accepting real vendor continuity risk on a component that is hard to swap out quickly.
  • The premium tier at a flat 999 US dollars a month is poor value below substantial volume, while the community edition omits the portal, transformations and RBAC that most production deployments end up wanting.
  • The hosted cloud trial is capped at one project and 100 events a day, which is too small to properly evaluate the service before committing.
  • Documentation and the third-party ecosystem are thinner than the established webhook services, so unusual configurations often mean reading the Go source.

Zeplo

  • Zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
  • The free Developer tier includes only 500 requests a month and one team member, so it is a demonstration allowance rather than a usable free plan for anything real.
  • Overage on the Developer tier is 20 US dollars per 100,000 requests, two hundred times the marginal rate on the Company tier, so exceeding the free allowance without upgrading is expensive.
  • Team members cost 15 US dollars each beyond the plan allowance, which is an odd charge on an infrastructure product billed by request volume.
  • Log retention is 30 days on both published tiers, so anything requiring longer audit trails on job execution has to be logged separately.

Answered from the vendors’ own pages

Convoy: Is Convoy really open source?

Yes, the community edition is open source and self-hostable, covering both inbound and outbound webhooks with retries.

Zeplo: How does Zeplo work?

You prefix your endpoint URL with zeplo.to and add query parameters for retries, delay, cron or concurrency. No SDK or broker is needed.

Convoy: What does premium cost?

A flat 999 US dollars a month, self-hosted, regardless of message volume.

Zeplo: What does it cost?

Free for 500 requests a month; 39 US dollars a month for a million requests, then 10 dollars per additional million.

Convoy: Does it receive webhooks as well as send them?

Yes, inbound ingestion with verification and deduplication is a first-class feature, unlike most webhook services.

Zeplo: Is it suitable for critical jobs?

It is a small vendor in your execution path with no published SLA below Enterprise, so weigh that against the convenience.

Convoy: Do I have to self-host?

No, there is a hosted cloud, but the trial is capped at 100 events a day and self-hosting is the primary model.

Zeplo: Does it work with serverless platforms?

Yes, that is its main use, covering Vercel, Cloudflare Workers, Netlify and similar environments that lack long-running workers.
