Norwich earned their second point of the season, but failed to take advantage of a host of chances to punish a below-par Brighton at Carrow Road.
Still searching for their first Premier League win of the season, the Canaries could not find a knockout punch despite their energy and industry ruffling the visitors.
American striker Josh Sargent squandered Norwich's best two chances and as the openings ebbed away so did his confidence.
Brighton move up the table to fourth, climbing above Manchester United - who lost to Leicester - and Everton, who play West Ham on Sunday.
