1 prototype live right now

Shubhanshu ships small SaaS, one subdomain at a time.

First one up: a scheduler and AI composer for Bluesky and X. One queue, drafts written for you, and previews that match the real thing. It's a working prototype you can open right now — not a case-study PDF.

One apex, one subdomain — for now
Everything here is running software, not a mockup.
Shubhanshu founder, protoapp.xyz

I work on the unglamorous middle of the creator stack — drafting, scheduling, and the queue that actually gets a post out the door.

It started as a tool I needed myself, got rebuilt once it worked, and now runs as its own small SaaS. The next subdomain goes up when it's finished, not before. The design system it's built on lives at ui.protoapp.xyz. Longer write-ups and what I build with are on shubhanshu.dev.
