We’re also able to indicate whether a connector was built with the Meltano SDK! Checkout https://hub.meltano.com/targets/yaml for an example of what that looks like in the UI. Behind the scenes it’s a simple

meltano_sdk: true

key on the YAML definition. If you’ve made a connector that’s listed on the Hub with the SDK, let me know and we can get it updated (or you can make an MR to add the key 🙂 )
