Phoenix + Absinthe GraphQL + Ecto Starter
Phoenix, PostgreSQL, Ecto SQL, Absinthe GraphQL, Phoenix Channels, and ExUnit form a backend service configuration where the generated project is centered on a backend service. Better Fullstack can scaffold this exact compatibility-checked selection.

Compatibility notes
Compatibility checked against Better Fullstack types version 2.8.0.
The generated record has 0 graph issues and 0 disabled selected options. This is a compatibility check, not a claim that this exact scaffold received a runtime smoke verification.
- Elixir Auth is intentionally set to none.
- Elixir Jobs is intentionally set to none.

Questions
Is this combination supported?
It passes the repository's compatibility analysis, selected-option checks, stack graph validation, project schema parsing, and virtual generation. That result is described here as compatibility checked.
Does it generate one app or separate parts?
The generated project is centered on a backend service. The actual generated output uses a single-directory layout.
How can I customize the selection?
Open the generated builder link above. Its query parameters reproduce this selection, and the builder can change compatible options before generating a new command.
