The current free version of the Liveblocks plugin for Bubble (https://bubble.io/plugin/liveblocks-by-lunch-pail-labs-1717457909317x496158240134922200) enables presence tracking and live cursors—perfect for basic real-time collaboration.
We’re considering a paid, full-featured version with advanced features like comments, notifications, and text editors (check out examples here: https://liveblocks.io/examples). Pricing would likely be $129 one-time (with a subscription option for those who prefer).
