Nostr relay infrastructure, deployable through AWS Marketplace in a couple minutes.
Overview
This product is a comprehensive Nostr relay server solution available on AWS Marketplace that enables you to quickly deploy and manage your own Nostr relay infrastructure. It provides automated deployment through CloudFormation, built-in SSL/TLS certificate management via Let's Encrypt, extensive monitoring capabilities, and a full test suite to validate functionality. The solution is designed for both individual relay operators and organizations looking to participate in the Nostr network while maintaining control over their infrastructure. It handles all the complex infrastructure setup and security configurations, allowing you to focus on operating your relay rather than managing infrastructure.
The Nostr Relay offers the following features:
- Optimized to run on ARM-based instances
- Built on nostr-rs-relay for optimal performance
- Docker-based deployment for consistency and isolation
- Automated Let's Encrypt certificate management
- Built using Amazon Linux 2023
- Automated backup integration with AWS Backup

Dimensions summary
You pay by the hour for the AWS Graviton instance type you choose to run the relay. Each dimension maps to a specific instance size, so pricing scales with the compute, memory, and storage you select. Smaller sizes like nano, micro, and medium suit light use, while larger sizes and metal options handle heavier workloads. Instance families differ by focus: compute-optimized (c-series), memory-optimized (r-series), general-purpose (m- and t-series), and storage-focused (i-series). You only pay for the hours your chosen instance runs, and you can switch sizes later.
Top-of-mind questions for buyers
One hour maps to one running AWS Graviton instance of the size you select. The charge covers the relay software fee layered on the underlying AWS compute, memory, and storage for that instance. You pay only for the hours the instance actually runs.
The hourly software fee meters running time only, so a stopped instance stops accruing that fee. Underlying AWS storage charges may still apply while data persists. If you change the instance type, a replacement instance deploys and billing follows the new size's hourly rate.
The hourly dimension covers the running relay instance. Daily backups are optional and run through AWS Backup, retaining copies for 30 days with KMS encryption. Any storage used by those backups is billed by AWS separately, not as part of the instance-hour fee shown in the table.

Delivery details
Single instance EC2 deployed with KMS and EBS
The CloudFormation template creates the following key resources:
- EC2 Instance running the Nostr relay software
- EBS volume for persistent data storage (size configurable)
- Elastic IP for stable public IP address
- Security groups allowing HTTP/HTTPS access
- IAM roles and policies for instance permissions
- KMS key for encryption of EBS volumes
- Optional Route53 DNS record pointing to the relay
- Optional AWS Backup plan for daily backups
- Optional SSH access if key pair and CIDR provided
The relay instance runs on an ARM-based t4g instance type (configurable size) and uses a custom AMI with the relay software pre-installed. The instance mounts an encrypted EBS volume for the Nostr database storage.
Security is enforced through IAM roles, security groups, and KMS encryption. The instance can be accessed via AWS Systems Manager Session Manager, with optional SSH access if configured.
CloudFormation Template (CFT)
AWS CloudFormation templates are JSON or YAML-formatted text files that simplify provisioning and management on AWS. The templates describe the service or application architecture you want to deploy, and AWS CloudFormation uses those templates to provision and configure the required services (such as Amazon EC2 instances or Amazon RDS DB instances). The deployed application and associated resources are called a "stack."
