DeckCalc is a deck calculator that counts deck boards, joists and screws, picks a joist size from the IRC span table and estimates the materials cost — with no account.
It was built to be fast and private. There are no accounts and no uploads; every calculation happens in your browser. The site may be supported by unobtrusive advertising, which never appears inside the tool itself.
