Competitor positions are our reading of Sweep, Watershed and Greenly public product material as at August 2026. Vendors name things differently, so rows are matched on capability rather than label, and their wording is noted where it differs. Partial means the capability exists in a narrower or adjacent form. Nothing here is published pricing, and none of these vendors publish token allowances.
