Figma's approach to real-time collaborative editing continues to generate significant interest in the developer community, with discussions highlighting both the technical achievements and the evolving landscape of multiplayer synchronization tools. The design platform's decision to build a custom solution using CRDTs (Conflict-free Replicated Data Types) instead of traditional Operational Transformation has become a reference point for understanding modern collaborative software architecture.
The technical discussion reveals how Figma abandoned conventional approaches when building their multiplayer functionality four years ago. They rejected both standard stateful features and Operational Transformation, the popular multiplayer algorithm at the time, finding that OT prevented their design tool from being responsive while maintaining consistency. Instead, they chose CRDTs as a simpler solution for their specific problem space.
Current State of Real-Time Collaboration Technology
The community discussion reveals that building real-time collaboration remains challenging even today. However, the landscape has evolved significantly since Figma's initial implementation. Several new sync engines have emerged to tackle this problem, including Rocicorp Zero and Electric SQL, though the space is still not crowded with options. These tools aim to make collaborative features more accessible to developers who might otherwise struggle with the complexity of implementing CRDTs from scratch.
Some developers point to existing solutions that have been available for years. ShareDB and Racer, for example, provided synchronized snapshots, conflict resolution, diffs, and change tracking over a decade ago. Additionally, platforms like Liveblocks.io have been working to make multiplayer collaboration easy and accessible, with their core focus on multiplayer editing capabilities.
Framework-Specific Solutions and Emerging Tools
The discussion also highlights framework-specific approaches to real-time collaboration. Elixir's Phoenix LiveView combined with PubSub covers many collaborative bases out of the box, though developers note that broadcast functionality isn't the same as true synchronization, and LiveView isn't suitable for all applications. Phoenix has recently added Phoenix.Sync, a sync engine library specifically designed to address these limitations.
There are now a few sync engines that tackle this problem. Rocicorp Zero, Electric SQL, and one or two others. By no means a crowded space, but there are options now.
The community recognizes that while the fundamental technologies for real-time collaboration have existed for decades, the implementation and accessibility of these solutions continue to improve. This ongoing evolution suggests that what was once a highly specialized technical challenge is gradually becoming more approachable for a broader range of developers.

Community Perspectives on Figma's Impact
Interestingly, the discussion extends beyond pure technical considerations to examine Figma's broader impact on the design industry. Some community members express concern about Figma's influence on design patterns and user experience practices, suggesting that the platform's own interface has become a reference point for designers, potentially perpetuating certain design approaches.
The conversation also touches on the origins of Figma's technology, with some suggesting that the company was initially focused on developing a real-time collaboration JavaScript engine and later found design software as an ideal application for this technology. This perspective frames Figma's success as much about timing and market fit as about technical innovation.
The ongoing community interest in Figma's multiplayer technology demonstrates the continued relevance of their technical decisions and the broader challenge of building responsive, collaborative software that can handle multiple users editing the same document simultaneously.
