Good question! With Encore, your application code is actually more portable than with Terraform because you are defining infrastructure semantically (eg. "I need a Postgres database"), not with cloud-specific config. The same code deploys to AWS, GCP, or even locally with Docker so no Terraform rewrite is needed when switching clouds.

As for the language support; we support Go and TypeScript today. We're focusing on making these rock-solid first, but more languages are on the roadmap. Python is the likely next candidate.
