# Choosing the right SDK

## Integrate with a cheqd supported SDK

cheqd has integrated into a suite of SDKs to enable third parties to create DIDs and DID-Linked Resources; and, issue and verify Verifiable Credentials, using cheqd DIDs.

## Choose a software stack to suit your needs

cheqd is continually integrating into different software development kits to suit the needs of different partners and their clients.

Below is a comparison between our supported SDKs, including: Credo, ACA-Py, Veramo SDK plugin and Walt.id's Community Stack.
