Tier lists

Pick your job. Get the meta.

Every list ranks real tools for one specific job on our public 100-point rubric.

⚠ Preliminary, based on public research, hands-on test pending. These scores come from a desk review of public sources (official pricing pages, docs, changelogs), linked on each tool page. Rex hasn't run the hands-on tests yet, so tiers shown are projected. Under our rubric, a tool's official tier is capped at B until it's tested.
