the xtarter ecosystem

Two tools, one standard

Start from a template, or bring an existing repo up to standard. Both land on the same conformance baseline.

scaffolding CLI

create-xtarter-app

New project, fully configured, in one command.

Pick a stack and start from the baseline.

Start with a template

conformance CLI

xtarterize

Bring any project up to standard without overwriting your files.

It detects the stack, plans the fixes, and writes nothing until you approve.

Conform your project

why conformant

Standards that hold their shape

Configs drift when enforcement lives in someone's head. This baseline lives in the repo instead.

Reviews that read themselves
Biome and strict TypeScript run from the first commit. Reviews cover features, not formatting.
CI that stays green
GitHub Actions runs the same configs your editor enforces, so local and CI cannot disagree.
Agent-ready by default
Agent skills ship with every config, so AI assistants follow the same standard you do.

Starter templates

Five starters. Each ships Biome, strict TypeScript, CI, VS Code settings, and agent skills before your first commit.
