This is a landscape, not a mandate — nothing here is a requirement, an endorsement for hire, or a paid placement. No affiliate links: every link points at the vendor's own site, unadorned, and we earn nothing from a click or a purchase. Entries marked ⚠ carry an unverified cost tier or platform — confirm on the vendor's page before relying on them. A tool's absence means nobody here has used it, not that it is bad.
