Owl20
Owl20 is a browser extension bridge between Beyond20 and Owlbear Rodeo. It is built for D&D Beyond users and Owlbear Rodeo groups who want dice rolls from a character sheet to appear in the Owlbear Rodeo room for the whole table, including attacks, saves, damage, crits, and other roll types Beyond20 can send.
The setup is split by role. On the player side, Owl20 is a lightweight browser extension; on the DM side, it uses an official verified Owlbear Rodeo extension. The site says player setup takes about five minutes and DM setup about three minutes. It also includes step-step guides for players and DMs, troubleshooting help, and a technical deep dive that mentions CustomEvents, postMessage, MutationObserver, and Manifest V3.
Owl20 is distributed for Chrome, Edge, and Firefox, and it is also available on the Firefox Add-ons store. The project describes itself as open source on GitHub, with both the browser extension and the Owlbear Rodeo extension in the repository. It is listed at $0 and has no premium tier. The site also says it has no accounts, no analytics inside the extension, and no server in the middle, with roll data traveling directly from the browser tab into the Owlbear Rodeo room and disappearing when the session ends.
