TLDR
-
A founder reflects on lessons from building a multiplayer browser at startup sail/muddy, aimed at builders exploring ambitious shared interfaces.
Key Takeaways
-
Multiplayer browsers attempt to synchronize browsing state across users in real time, a fundamentally hard coordination problem.
-
sail/muddy was a startup explicitly working on shared, collaborative browsing as a product, not a side experiment.
-
The lessons are framed as durable takeaways for anyone building new interface paradigms, not a postmortem on a single failed feature.
-
The timing of the post is deliberate: the author sees renewed relevance as AI changes what ambient, shared interfaces can look like.
