Decks.com Deck Designer Alternatives (Real Limits Compared)
Decks.com Deck Designer is a solid choice, but people look for alternatives because of the fine print: Free to design and download plans plus a suggested material list after a free signup, but you cannot change the framing lumber sizes and the materials are a suggested list, not a guaranteed takeoff. On top of that, free account required to save and download. Strong options to compare include Trex Deck Designer and Lowe's Deck Designer. Below we line up the real free limits of each — what it exports, what it watermarks, and which platforms it runs on — so you switch for the right reason.
Alternatives at a glance

Free, brand-lockedCompletely free with no payment and no export paywall, but every board, railing and SKU it prices is a Trex composite product, so the shopping list only works if you actually buy Trex.
Lowe's Deck Designer
Free, brand-lockedFree with no purchase or account upgrade, but the material list and prices are pulled from Lowe's own inventory and the plans are not engineered or permit-ready.
