FreeBSD is an advanced computer operating system used to power modern servers, desktops, and embedded platforms. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive networking and storage devices.
FreeBSD is an operating system used to power servers, desktops, and embedded systems. Derived from BSD, the version of UNIX developed at the University of California, Berkeley, FreeBSD has been continually developed by a large community for more than 30 years. FreeBSD's networking, security, storage, and monitoring features, including the pf firewall, kernel TLS, the Capsicum capability frameworks, the ZFS filesystem, and the DTrace dynamic tracing framework, make FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage systems.
Highlights
FreeBSD provides access to over 34,000 third-party applications via the ports tree and binary packages.
FreeBSD's widely-recognized stability and reliability and lengthy support for stable branches makes it ideal for building long-lived services.
Between Capsicum, Jails, and support for multiple firewalls, FreeBSD provides an unsurpassed security feature set.

See AWS Free Tier for more details. If you created an AWS account before July 15th, 2025, and qualify for the Legacy AWS Free Tier, Amazon EC2 charges for Micro instances are free for up to 750 hours per month. See Legacy AWS Free Tier for more details.
You pay nothing for the FreeBSD/amd64 15 (UFS) software itself — it is a free, open-source operating system. Pricing here is organized entirely by EC2 instance type, and each option is billed hourly. Every dimension names a specific instance (for example, t3.large, r5.4xlarge, or m8i.metal-96xl). The dimensions are not feature tiers; they map to compute sizes and families. You choose the instance that fits your workload, and your hourly cost scales with the instance you select, since the software carries no license charge.
Top-of-mind questions for buyers
What does one hour of billing cover, and am I charged when the instance is stopped?
Each dimension bills per hour that the chosen EC2 instance runs. The software carries no license charge, so the hourly rate reflects the instance you select. A fully stopped instance stops accruing hourly charges, though AWS storage fees for the volume may still apply.
How do I choose between the many instance dimensions, and what changes my cost?
Each dimension maps to a specific EC2 instance size and family, not a feature tier. You pick the instance that matches your compute, memory, or storage needs. Larger instances cost more per hour. Since FreeBSD is free and open-source, only the instance choice drives your hourly cost.
Does switching to a different instance type change my software cost or require a new license?
No license is involved. FreeBSD is distributed under the permissive BSD License at no cost. Moving to another instance changes only your hourly compute rate, which follows the new instance's size and family. You can select any listed instance without a separate software fee.

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.

Usage instructions
This AMI launches with sshd running and the SSH public key you provide at launch time allowed to log in as ec2-user with passwordless "su" to root. To use this AMI, ensure that your EC2 security group allows SSH (tcp/22) from your location, and then "ssh ec2-user@<Instance IP address>".
