Is Caddy or DeepInfra better?

Neither clearly leads. Caddy starts at Free and DeepInfra at $0.08/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Caddy or DeepInfra?

Caddy has a free tier; the other does not. Paid plans start at Free for Caddy and $0.08/month for DeepInfra.

Does Caddy or DeepInfra run on more platforms?

Caddy runs on Linux, macOS, Windows, Docker. DeepInfra runs on web, api.

Can I use Caddy for free?

Yes. Caddy has a free tier, so you can try it without paying. DeepInfra starts at $0.08/month.

What is Caddy best used for?

Caddy is most often used for sites and services where expired certificates have caused outages before, small deployments where nginx configuration is more effort than the problem warrants, reverse proxying internal services with tls without a certificate workflow. Of those, sites and services where expired certificates have caused outages before and small deployments where nginx configuration is more effort than the problem warrants are not what DeepInfra is typically brought in for.

What can Caddy do that DeepInfra cannot?

Caddy covers Automatic HTTPS, Caddyfile, Reverse proxy, Single binary. DeepInfra covers Open model hosting, Pay-per-token pricing, Long context support, DeepCluster.

The short version

Only Caddy has a free tier, so it costs nothing to try first.
Each has a real cost: Caddy smaller ecosystem than Nginx, so third-party guides and modules are fewer; DeepInfra focuses on inference hosting rather than fine-tuning or full training pipelines that competitors like Fireworks AI offer.
They diverge on capability: Caddy covers Automatic HTTPS, DeepInfra covers Open model hosting.

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

DeepInfra

Focuses on inference hosting rather than fine-tuning or full training pipelines that competitors like Fireworks AI offer.
Model selection is limited to what DeepInfra chooses to host, unlike self-managed platforms.
No published free tier; usage is billed from the first token.

Answered from the vendors’ own pages

Caddy: Is Caddy free?

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

DeepInfra: Is there a free tier on DeepInfra?

No free tier is published; usage is billed pay-as-you-go from the first token, though a credit card or pre-payment is required before you can send requests.

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.

DeepInfra: How is usage priced?

Language models are billed per million input/output tokens, other models by inference execution time, and audio models per minute of audio processed, with no minimum commitment.

Source

Caddy: Caddy or Nginx?

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

DeepInfra: What are the Standard, Priority, and Flex tiers?

Standard is default best-effort pricing at 1x, Priority costs 1.5x for faster time-to-first-token during peak demand, and Flex costs 0.8x for non-production or asynchronous workloads.

Source

DeepInfra: How does billing scale with spend?

Accounts advance through usage tiers as cumulative payments cross $20, $100, $500, $2,000, and $10,000 thresholds, with invoices generated monthly or at each threshold.

Source

DeepInfra: Is there a limit on concurrent requests?

Yes, accounts are limited to 200 concurrent requests by default, though spending limits can also be configured to prevent unexpected charges.
