Building Reliable Multi-User Editors: The CRDT vs OT Algorithm Decision

Choosing between CRDT and OT collaboration algorithms fundamentally shapes your editor's architecture—affecting offline behavior, metadata overhead, and long-term maintenance costs. Understanding the trade-offs between transform-first (OT) and merge-first (CRDT) approaches is essential for teams building modern collaborative tools, as wrong algorithm choices often lead to months of edge-case fixes or persistent scalability issues.
