twitter.com@nerdburnIt’s fun, feels lightweight, and really quick to spin up user auth and a few tables. Almost too easy! Highly recommend.

x.com@patrickcVery impressed by @supabase's growth. For new startups, they seem to have gone from "promising" to "standard" in remarkably short order.

x.com@Aliahsan_sfvOkay, I finally tried Supabase today and wow... why did I wait so long? 😅 Went from 'how do I even start' to having auth + database + real-time updates working in like 20 minutes. Sometimes the hype is actually justified! #Supabase

x.com@yatsiv_yuriySupabase is the best product experience I've had in years. Not just tech - taste. From docs to latency to the URL structure that makes you think "oh, that's obvious" Feels like every other platform should study how they built it @supabase I love you

x.com@adeelibr@supabase shout out, their MCP is awesome. It's helping me create better row securities and telling me best practises for setting up a supabase app

x.com@TyronBacheReally impressed with @supabase's Assistant. It has helped me troubleshoot and solve complex CORS Configuration issues on Pinger.

x.com@MinimEditorI’ve always used Supabase just as a database. Yesterday, I helped debug a founder’s vibe-coding project built with React + React Router — no backend server. The “backend” was entirely Supabase Edge Functions as the API. First time using Supabase this way. Impressive.
