Summary
The Retool app editor has suddenly become extremely slow and effectively unusable, even after clearing cache, deleting components, stopping queries, checking internet speed, and restarting the machine — despite working fine the prior week.
AI Response
Sudden editor slowness like this most often traces back to one of two things on Retool Cloud. First, try closing/collapsing the Graph (dependency) pane in the editor — an accepted community solution resolved identical slowness this way. Second, transient Cloud latency has produced this exact 'came out of nowhere' behavior for others and cleared on its own within hours. Since these are the confirmed patterns, collapsing the Graph pane is the fastest thing to try right now, and if load times are purely spinner-based, monitoring for a short period may show it self-resolve.
