Has anyone used hook.io as an alternative? I have only built toy projects with it, nothing substantial, so I can't speak to important things like error handling, but so far I really like it and find it substantially easier to use than Lambda.
We haven't had any recorded incidents of lost data. We did have an issue after a security upgrade where older accounts did need to be migrated with new access tokens. If you lost any data drop me an email and I'd be glad to find it.
The internal datastore is mostly for development purposes. We generally recommend persisting data to an external database like DynamoDB.
If it would make you more inclined to try the platform, I'm glad to adjust the tone of the copy. I get easily excited!
