In building sizuq, I’m hosting the Next.js side on Vercel and keeping the PostgreSQL database on Neon. My free Supabase tier was already used up on an existing project, so I decided to try Neon, which has similar features. When I looked into how many total posts and users Neon’s free plan can handle, the answer was that for text-based posts without images, it can hold up to 30,000–100,000 posts and several thousand to 10,000 users. It sounds like there are also issues of uptime and data transfer, not just data volume, but for a hobby project it seems more than enough for now. Everything I used to build sizuq was Claude Code. Personally, I much prefer the design feel, the server-side rendering, and the 0.35s transition between screens to X, note (a Japanese blogging platform), Instagram, Threads, and the like (which is obvious, since I’m the one who directed Claude to make it) and that makes me happy.
