The short version

  • Each has a real cost: Caddy smaller ecosystem than Nginx, so third-party guides and modules are fewer; 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.
  • They diverge on capability: Caddy covers Automatic HTTPS, Convoy covers Inbound and outbound.
  • 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.

Caddy

  • Sites and services where expired certificates have caused outages beforenot Convoy
  • Small deployments where Nginx configuration is more effort than the problem warrantsnot Convoy
  • Reverse proxying internal services with TLS without a certificate workflownot Convoy

Convoy

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

Where each one falls short

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

Caddy

  • Smaller ecosystem than Nginx, so third-party guides and modules are fewer
  • Adding plugins means rebuilding the binary rather than loading a module
  • Under very high throughput Nginx generally still benchmarks ahead
  • Automatic certificate issuance needs outbound internet access, which complicates air-gapped deployments

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.

Answered from the vendors’ own pages

Caddy: Is Caddy free?

Yes, open source under the Apache 2.0 licence, free for commercial use.

Convoy: Is Convoy really open source?

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

Caddy: What does automatic HTTPS mean?

Caddy obtains certificates from Let’s Encrypt or ZeroSSL on first request and renews them before expiry, with no cron job or configuration.

Convoy: What does premium cost?

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

Caddy: Caddy or Nginx?

Caddy is dramatically simpler to configure and removes certificate management. Nginx has the larger ecosystem and better peak throughput.

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.

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.
