Mirror allows you to listen to offchain events or poll offchain resources & mirror that data to other chains
We use the Transaction Cloud to broadcast data to target chains. Sign up here for a free account.

Currently we run this service in Cloud Run with min instances set to 1 so the service will never spin down. The code is unopinionated and does not use external resources such as a database or a memcache & is easy to deploy to other cloud providers such as Render, fly.io, Heroku, etc. The main thing to keep in mind is you want this service to always be on so you are always listening for data.
