Everything's better with friends
summary
Claims that real-time collaborative apps become practical by pushing sync to the edge and using process-isolated documents. Uses Cloudflare Durable Objects and a small platform called pikit to wire websockets/Yjs into per‑document isolates (about 30–40 concurrent users each) with ~128MB RAM limits. Builds a shared counter, a TLDraw demo and a crowd music prototype; counter and drawing work, demos hit platform limits and the music demo fails on iPhones.
