This listing is free to use, with no software charge. You pick one of four AWS EC2 instance types to run the software: t3a.large, t3.medium, t2.large, or t3.small. These options are not feature tiers. They differ only in compute size and the AWS infrastructure cost you pay for the instance you choose. Larger instances offer more CPU and memory for heavier workloads, while smaller ones suit lighter use. You run the software in your own environment, so your automation and credentials stay under your control.
Top-of-mind questions for buyers
What resources do I get with each hourly instance option like t3a.large or t3.medium?
Each option maps to an AWS EC2 instance type with a set amount of CPU and memory. Larger types like t3a.large and t2.large give more compute for heavier automation runs. Smaller types like t3.medium and t3.small suit lighter workloads. You pay the AWS infrastructure cost for the type you run.
Am I charged when my chosen instance is stopped or paused?
The software itself is free, so there is no software charge. You pay AWS infrastructure cost only while the instance runs. A stopped instance stops accruing compute charges, though AWS storage fees for the attached volume may still apply. Restarting resumes the hourly compute cost.
Do I run this software in AWS or on my own servers?
You run it in your own AWS environment on the EC2 instance type you pick. The software is self-hosted, so your automation and credentials stay under your control. You install it as a single binary, a container image, or a Kubernetes deployment.

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
Improved project runners UX, added support for tags and limits for Ansible templates.
