Pricing
RAG Engine is included in the AppXen Platform appliance. You pay AWS Marketplace for the appliance and AWS for the resources it runs on, in your own AWS account.
What the appliance costs
RAG Engine is part of the AppXen Platform appliance (MCP Gateway Pro, RAG Engine, Agent Orchestrator and the console). It has no price of its own. The appliance is sold through AWS Marketplace at:
- $0.149 per instance-hour, or $949 per year, on the large instance types (
t3.largeis the default, thent3a.large,m6i.largeandm6a.large) - $0.199 per instance-hour, or $1,299 per year, on the xlarge instance types (
t3.xlarge,t3a.xlarge,m6i.xlargeandm6a.xlarge)
The annual price is one yearly charge for one instance, in place of the hourly rate.
AWS Marketplace bills this on your AWS bill.
Your own AWS usage
The appliance runs in your own AWS account, so the AWS resources it uses are billed to you by AWS, separately from the Marketplace price:
- The EC2 instance (
t3.largeby default) - The encrypted gp3 root volume (50 GiB by default)
- An Elastic IP
- Five DynamoDB tables
- Three S3 buckets
- An SQS queue and its dead-letter queue
- Amazon Bedrock tokens. Bedrock usage is extra: AWS bills it to your account, and it is not in the estimate below
- Amazon Textract, if you ingest images (the RAG Engine reads their text with it)
AppXen does not meter requests, storage or tokens and never sees your data.
A monthly estimate for the default configuration
For the default configuration (t3.large, 50 GiB root volume, us-east-1, running all month, priced 2026-09-29), the AWS infrastructure comes to about $70.11 a month. With the Marketplace price on top, before any Bedrock usage:
| Line | Basis | Monthly |
|---|---|---|
EC2 t3.large | 730 hours | $60.74 |
| gp3 root volume | 50 GB-month | $4.00 |
| Elastic IP | 730 hours | $3.65 |
| DynamoDB, on-demand | 1,000,000 writes and 5,000,000 reads | $1.26 |
| S3 Standard | 20 GB-month | $0.46 |
| SQS | 1,000,000 requests (inside the AWS free tier) | $0.00 |
| AWS infrastructure | $70.11 | |
| Marketplace, hourly | $0.149 x 730 hours | $108.77 |
| Total at the hourly rate | before Bedrock | about $178.88 |
| Marketplace, annual | $949 per year, as a monthly equivalent | $79.08 |
| Total at the annual rate | before Bedrock | about $149.19 |
These are the large-type prices. On an xlarge type the Marketplace price is $0.199 per instance-hour (about $145.27 a month) or $1,299 per year (about $108.25 a month), and the instance itself costs more at AWS's own rate.
This is an estimate, not a quote. Another instance type, another Region, your discounts and your real usage all change it. Add your Amazon Bedrock usage on top: see the Amazon Bedrock pricing page for the per-token prices of the models you use.
When you stop using it
Deleting the CloudFormation stack removes the instance and the rest of what the stack built, with these exceptions:
- The five DynamoDB tables, the three S3 buckets and the SQS queue pair are retained. They stay in your account, and AWS keeps billing you for what they hold, until you delete them yourself when you no longer need them.
- The Postgres RAG index lives on the instance's root volume and is deleted with it. Only the S3 backups under
postgres/survive, and they expire after 30 days. - The AWS Marketplace subscription is managed in AWS Marketplace, in your AWS account.
