Overview
Repstance transforms "Complex to Simple and Difficult to Easy". Repstance is an innovative and extremely versatile, Enterprise Class data Facilitation tool. By "Facilitation" we mean that, by using Repstance you are able to deploy, distribute, change and use your most valuable asset - your Data - in ways that are either, not available or are cost prohibitive when compared with other solutions, as well as performing the more basic Migration and ongoing Replication functions, whether that be on your own premises or "In the Cloud". Repstance is extremely easy to deploy and use via a simple, interactive and highly intuitive GUI but also has an interactive CLI (Command Line Interface) for those users who are more accustomed to this environment.
- Repstance is currently listed on the AWS platform and currently supports: Oracle 10G through 19C - using either LogMiner, Redo-logs or ASM as the Data Capture method. The last 2 significantly reduce any loading on an Oracle DB when it is used as the Source. Any version of MSSQL Server that permits the use of CDC (Change Data Capture) as Source DB's Oracle10G - 19C, SQL Server as Target DB's. Repstance is ideally suited for the following Use Case Scenarios: Migration. Replication. Blue/Green upgrade strategies. Zero Downtime Migrations and upgrades. Disaster Recovery and "Hot Standby" provisioning. Multi node, Multi Cluster for "Load Balancing provision", "High Availability" and "Always On" scenarios. Offloading of BI reporting functionality. Data Warehousing and Data Lake provisioning. Cross Vendor Platform redundancy. Plus many other Topologies and requirements.
- Repstance has DDL replication as part of the standard feature set out of the box, which permits it to include DDL and DML objects automatically into the replication process without needing additional user input.
- Repstance Capture and Apply processes are mutually independent, so that it is possible, not to have target databases continuously available, as long as the Capture processes on the source database continues to be run and is generating the required Trail files.
- Repstance can, represent itself as an MS SQL replication Agent - which allows it to simulate SQL Server replication behaviour.
- Repstance can start replicating data from any desired timestamp.
- Repstance is possibly the fastest Replication, Migration and Deployment solution currently available.
- Repstance supports Multi-Master replication in all forms of topology with ability the to ignore data produced by itself (loopback control), thus providing "True" Bi/Multi-Directional replication, therefore ensuring all instances are equal and continuously synchronised, any changes made in one node will be propagated (replicated) into the other nodes.
Highlights
- Oracle, SQL Server, CDC, Replication, Transformation, Migration
- Consistent Data Integrity, Reliability and Exceptional Speed

Dimensions summary
You pay by the hour based on the EC2 instance size you run Repstance on. The ten options span two instance families (m4 and m5) in sizes from xlarge up to 24xlarge. Pricing scales with the compute capacity you choose: larger instances carry more CPU and memory and bill at a higher hourly rate. You pick the size that fits your replication or migration workload, then run it as long as you need. There is no upfront commitment; charges accrue per hour of use.
Top-of-mind questions for buyers
The hourly rate covers the Repstance software running on your chosen EC2 instance. The underlying AWS compute, storage, and data transfer bill separately through your AWS account. You pick an m4 or m5 size to match your replication workload, then pay per hour the instance runs.
Software charges accrue per hour the instance runs. When you stop the instance, software metering pauses. Stopped instances may still incur AWS storage fees for attached volumes, but the Repstance software bills only for running time. Start the instance again when you need to resume replication.
Some setups use two Repstance instances — one to capture data from the source and one to apply changes to an isolated target, communicating through S3. Each running instance bills separately at its hourly rate. Distributed topologies also use multiple instances, so plan for the total compute hours across all instances.

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
Version 6.0.0018. Security: fixes CVE-2026-111497 (Brotli). Faster apply. Faster Oracle capture. Minor bug fixes. The large instance types are no longer offered.

Usage instructions
Repstance is ready right after launch.
- Open the Web UI: https://<Public DNS of this instance>:3000 (the certificate is self-signed: accept the browser warning).
- Log in as "repstance". The password is the Instance ID of this instance (i-xxxxxxxxxxxxxxxxx, shown in the EC2 console). The same Instance ID is the token of the REST API.
- Command line: ssh -i <your-key>.pem ec2-user@<Public DNS>, then run: sudo repcli status
- Add your source and target databases in the Web UI (Getting Started: https://repstance.com/help ). Notes
- The instance must reach your source and target databases (security groups, routes).
- Data comparison and asyncredo need an instance with at least 32 GB RAM (m5.2xlarge or larger). Replication runs on smaller instances.
- Open ports 22 and 3000 only to your own address range. The Web UI does not need port 8797 (REST API).
- Repstance is billed hourly through AWS Marketplace. No license key is needed.
- Update the software: sudo dnf update repstance Support: support@repstance.com
To connect to the operating system, use ssh client. The username is "ec2-user".
In order to successfully use the product go https://repstance.com/help for the details.

Review from a verified AWS customer
We are using this product which runs on AWS for the SQL Server RDS migration on blue green upgrade. Earlier we where using SSIS packages to migrate data from blue to green to support Zero Down Time upgrades. But we ran into big issues with large customers and data was not migrating fast enough. Then we tried using Repstance and it so easy to use and really powerful. The data migration ran 20 times faster than our SSIS packages. And then we replaced our custom SSIS tool with repstance and works perfectly fine.
