Compatibility Matrix

Check whether Better Fullstack options work with a selected baseline stack.

Better Fullstack validates stack choices before generation. The builder, CLI, and MCP server all rely on shared compatibility logic so invalid combinations are rejected or adjusted consistently.

Check a Stack Combination

Start from a default baseline, adjust the key fields, then inspect one option category.

Ecosystem

Baseline Stack

These fields affect compatibility for the selected category.

What This Checks

Whether an option is compatible with the selected baseline stack.
The shared disabled reason when a combination is blocked.
Any automatic adjustment notes from the same compatibility analyzer used by the builder.

How To Use It

Pick an ecosystem.
Adjust the baseline stack fields that matter to your question.
Pick a category to inspect.
Review which options are compatible and why any are blocked.

This is intentionally a practical matrix, not every possible pairwise combination. For full project validation, run the CLI or use the Stack Builder before scaffolding.

Compatibility Behavior

none disables optional categories when supported.
Some selections trigger automatic adjustments, such as Convex replacing backend-owned database/API choices.
Some frontend choices intentionally narrow API, UI, runtime, or deploy support.
Java, Rust, Python, and Go use ecosystem-specific categories instead of the full TypeScript stack surface.
