Supabase Storage has been launched, but Functions are not available yet. Instead, Supabase is building Workflows, an orchestration engine that coordinates and executes existing functions in response to database events or HTTP calls. This tool will be built with Elixir and integrated with Postgres for deep integration with databases. It will have a Zapier-like interface for prototyping and version control with Git. Workflows are designed to be stateless, persistent, and transient, allowing developers to rapidly develop microservices without worrying about servers.
