Any differences from the AWS one: https://github.com/aws-cloudformation/custom-resource-helper

Instead of either that or particular library or this one for custom resources, I would suggest that it's now much better to create a resource provider than to use a custom resource Lambda function. Resource providers become proper CloudFormation types, and the AWS-provided resource provider framework is much more robust and capable of handling things like long-running operations that go beyond the 15-minute timeout for Lambda functions.
