The short version

  • Each has a real cost: Beam Cloud free tier limited to $30 monthly credits with 5 GPU containers; Caddy smaller ecosystem than Nginx, so third-party guides and modules are fewer
  • They diverge on capability: Beam Cloud covers Sub-second cold starts, Caddy covers Automatic HTTPS.
  • Prices and features above were last checked on 29 August 2026.

What people use each for

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

  • Large-scale batch processing across thousands of concurrent tasksnot Caddy
  • Cost-effective inference serving with bursty workloadsnot Caddy
  • Multi-cloud AI deployments with global low-latency accessnot Caddy
  • Serverless AI development for rapid experimentationnot Caddy

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

Where each one falls short

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

Beam Cloud

  • Free tier limited to $30 monthly credits with 5 GPU containers
  • Massive parallelization complexity may require DevOps expertise
  • Per-millisecond pricing model requires careful cost monitoring
  • Smaller team relative to established cloud providers

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

Answered from the vendors’ own pages

Beam Cloud: What is included in the Developer plan?

The Developer plan includes $30 monthly free credits, 5 GPU containers, 30 CPU containers, and community support. No upfront commitment is required.

Source
Caddy: Is Caddy free?

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

Beam Cloud: How fast are the cold starts?

Beam Cloud achieves sub-second cold starts through memory snapshots that restore GPU containers 35x faster than traditional cold boots.

Source
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.

Beam Cloud: Can I deploy across multiple cloud providers?

Yes, Beam Cloud supports multi-cloud deployment across AWS, GCP, Azure, Hetzner, and other providers with 30+ global regions available.

Source
Caddy: Caddy or Nginx?

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