On September 9, 2026, Shopify Inc. announced it had acquired Tailwind Labs Inc., the company behind the open-source Tailwind CSS framework, with Tailwind Labs stating on its blog that existing customers of Tailwind Plus and ui.sh will retain access, while sign-ups for new customers are closing so the team can focus on Tailwind CSS at Shopify. Osler's own representative-work page states that on September 9, 2026, Shopify announced its acquisition of Tailwind Labs, and the acquisition secures a stable, long-term home for Tailwind, where it will continue to be actively maintained. Ottawa-based Shopify acquired Tailwind Labs, the Canadian company behind the popular, free, open-source web development framework Tailwind CSS, with the financial terms of the deal not disclosed. Trade coverage has noted that the announcement's wording, "joining Shopify," leaves the structure of the transaction undefined, since "joining" can cover an acquisition, an employment agreement for the team, an investment, or a commercial partnership, and the available announcement does not establish a purchase price, equity terms, or the ownership and governance of Tailwind CSS. Osler, Hoskin & Harcourt LLP advised Shopify, with a team of three lawyers in its Toronto office. The deal follows a sharp contraction at Tailwind Labs: in January 2026, Tailwind Labs had laid off 75 percent of its engineering team after revenue fell nearly 80 percent and documentation traffic declined 40 percent over two years.
