where can use sandbox in InterSystems IRIS Data Platform 2025.3

You can use sandbox capabilities in the InterSystems IRIS Data Platform as an analytics sandbox. It provides a single tool for integration purposes, such as creating DataOps applications, BI tools, and analytical processes. InterSystems IRIS allows you to work with various programming languages including Java, Python, .NET, Node.js, and ObjectScript, and supports performing analytics and data visualizations directly within the platform [1].

You can spin up a container sandbox for playing with via Try IRIS:

Easiest way is with the community edition in a local docker container. Install docker and then run: 
 

docker run --publish 52773:52773 --publish 1972:1972 intersystems/iris-community:2025.3

You can also check out some of the dev templates which put this in a docker-compose file so you can clone a repo and run a working version with example code with just a couple of commands. You just have to make sure that in the Dockerfile it is pulling from version 2025.3 (or latest-cd).
