This is a repackaged open source software product wherein additional charges apply for image hardening, maintenance, and support. Caddy web server on Amazon Linux 2023, security-hardened for production: minimal package set, SSH key-only access, IMDSv2-only, runs as a non-root user, firewall pre-configured for HTTP/HTTPS, and continuously patched images.
Overview
Caddy (Hardened) on Amazon Linux 2023 is a production-ready, security-hardened image of the Caddy web server and reverse proxy, maintained and supported by Derek Coleman & Associates Inc.
This is repackaged open-source software. Caddy is developed by the Caddy project community and is distributed under the Apache License 2.0. This listing is not endorsed by or affiliated with the Caddy project. This product builds Caddy from unmodified upstream source with the current patched Go toolchain (so known standard-library vulnerabilities in prebuilt binaries are absent) on a hardened Amazon Linux 2023 base; the charges associated with this listing are for image hardening, continuous patching, vulnerability scanning, and business-day support - not for the underlying open-source software, which remains free.
Hardening baseline: minimal package footprint, SSH key-only access (password authentication disabled), IMDSv2 enforced, Caddy running as a dedicated non-root user with only the bind capability, host firewall exposing only web ports, and no default credentials anywhere. Automatic HTTPS activates once you configure a real domain in the Caddyfile. Images are rebuilt, scanned for HIGH and CRITICAL vulnerabilities, and republished on a regular cadence so that new launches start current. Configure sites in /etc/caddy/Caddyfile and manage the service with systemd: sudo systemctl restart caddy.
Highlights
- Production-ready: systemd-managed Caddy 2.11; automatic HTTPS once you point a domain at your Caddyfile.
- Security-hardened at build time: minimal packages, key-only SSH, IMDSv2-only, non-root service user, firewall enabled with only web ports open.
- Continuously patched: rebuilt, vulnerability-scanned, and republished on a regular cadence.

Pricing
Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
Dimension | Cost/hour |
|---|---|
c7i.xlarge Recommended | $0.46 |
c7i.4xlarge | $1.84 |
c7i.2xlarge | $0.92 |
Dimensions summary
You pay by the hour for the instance size you run. All three options bill the same hardened Caddy image; only the compute size differs. The c7i.xlarge gives you 4 vCPU and 8 GiB memory. The c7i.2xlarge gives you 8 vCPU and 16 GiB. The c7i.4xlarge gives you 16 vCPU and 32 GiB. Software charges cover image hardening, patching, and business-day support. AWS infrastructure charges are separate and billed by AWS. There is no subscription and no minimum. Charges stop when you terminate the instance.
Top-of-mind questions for buyers
The software charge covers image hardening, continuous patching, vulnerability scanning, and business-day support. The underlying Caddy software stays free under its open-source license. You pay for the security-hardened build, regular rebuilds, and launch support, not for the web server code itself.
Software charges accrue per running hour. When you terminate an instance, charges stop. There is no subscription and no minimum. Note that AWS may still bill for storage on a stopped instance's EBS volume, since that is separate infrastructure billed by AWS.
A single instance uses one EC2 instance and one gp3 EBS volume. No other AWS resources are created. Your hourly software charge covers the hardened image; AWS bills the compute and the EBS volume separately on your AWS invoice.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
[Security] Refreshed image: rebuilt on the latest hardened Amazon Linux 2023 baseline; all OS packages current at build.

- Edit /etc/caddy/Caddyfile to define your sites (replace the placeholder :80 block with your domain to enable automatic HTTPS), then: sudo systemctl restart caddy.
- Verify: curl -I http://<public-ip> returns a response, or: sudo systemctl status caddy.
- Sensitive data: there are no passwords or secrets anywhere in this product. Logs under /var/log may contain client IPs - treat as personal data.
- Backup: snapshot the EBS volume (it contains all configuration and data).
