Is there a way to list all resources in AWS

You can use the Tag Editor.

1. Go to AWS Console
2. In the TOP Navigation Pane, click Resource Groups Dropdown
3. Click Tag Editor

Here we can select either a particular region in which we want to search or select all regions from the dropdown. Then we can select actual resources which we want to search or we can also click on individual resources.

Yes. Use the Tag Editor.

Set "Regions" to "All Regions", "Resource Types" to "All supported resource types" and then click on "Search Resources".

I think this may help! Here, you need to enter the region name and you have to configure AWS CLI before try this.

aws resourcegroupstaggingapi get-resources --region region_name

It will list all the recourses in the region by the following format.

- ResourceARN: arn:aws:cloudformation:eu-west-1:5524534535:stack/auction-services-dev/*******************************
  Tags:
  - Key: STAGE
    Value: dev
- ResourceARN: arn:aws:cloudformation:eu-west-1:********************
