DeckSketch vs Trex Deck Designer
Trex's free browser-based 3D deck designer that lets homeowners lay out a deck, pick Trex products and colors, and export a materials shopping list, a rough cost estimate, and a permit-ready blueprint.

What Trex Deck Designer does well
- Completely free with no account required to start, backed by a major decking manufacturer
- Real 3D visualization with actual Trex product colors and railing styles
- Auto-generates a materials shopping list plus a rough cost estimate (with or without labor)
- Produces a downloadable blueprint you can hand to a contractor or planning office
Where DeckSketch wins
- No structural engineering — you can pick lumber size/species, but no automated joist/beam/footing sizing
- No code span calculations, so the framing is not verified against building code
- Cost estimate is Trex-product-oriented and rough, not a live itemized quote
- Desktop-only and centered on Trex products rather than neutral material choices
Pick Trex Deck Designer if…
- You're a homeowner who wants to visualize a deck and compare Trex colors for free
- You've already chosen Trex composite and want a shopping list and rough budget
- You need a simple blueprint to start the permit conversation
Pick DeckSketch if…
- You need framing auto-generated and sized against code span tables, not just a lumber picker
- You want a complete itemized BOM plus instant pricing that stays in sync as you edit
- You're a contractor who needs a repeatable design-to-estimate workflow
