OpenWrap is PubMatic's header bidding wrapper for publishers. It was released in April 2016, expanded in 2017 into a Prebid.js-based hybrid client- and server-side wrapper, and later extended to mobile apps and OTT/CTV. In July 2026 PubMatic shelved the web version (OpenWrap Web), with a sunset planned for December, and named Playwire its recommended migration partner; the in-app OpenWrap SDK continues.
