The 4 P’s of shipping a prototype

Get real feedback on your prototype — without making anyone install a thing.

You built something in a browser. Sharing it for review shouldn’t mean “clone the repo, run a dev server, install an extension.” With ReviewSX you send one link. Your reviewer opens it, clicks any element on the page, and leaves a pinned comment — which shows up right in your editor.

Sharing a prototype for review is broken

  • “Just pull the branch and npm install” — to a designer or a client.
  • Screenshots in a thread, with feedback like “the button, third one down.”
  • A staging deploy nobody can comment on — only about, elsewhere.
  • Feedback scattered across Slack, email, and sticky notes you re-type later.

ReviewSX is one link

  • Reviewers open it in any browser — no account, no repo, no IDE.
  • They click any UI element and drop a numbered, in-context comment.
  • An optional guided tour walks them through exactly what to look at.
  • Every comment lands back in your editor, pinned to the real element.

How it works

Four steps, one link

1

Prototype

Build whatever runs in a browser — static HTML, React/Vite, Next.js. ReviewSX wraps it; you don’t change your code.

2

Publish

One click turns it into a shareable link — a live tunnel to your machine, or a static deploy. No build pipeline to babysit.

3

Position

Author a quick guided tour so reviewers look at the right things, in the right order — even across routes and tabs.

4

Procure feedback

Reviewers pin comments to real elements. Threads, replies, resolve/archive — all flowing back into your editor.

Who it’s for

Two ways to run it

Startups & solo builders

You vibe-coded something great and your boss or client is travelling with no dev tools. Just send the link.

  • Free hosted inbox at inbox.reviewsx.app — nothing to run.
  • Share a live link straight from your editor.
  • Reviewers need zero setup; you get pinned feedback back instantly.

Mid-market & enterprise

Private repos, IP sensitivity, busy reviewers who want a company-hosted link. Keep everything on your own network.

  • Self-host the inbox on your own AWS/Azure via Docker Compose.
  • Bring your own Postgres; data never leaves your network.
  • The same one-link review flow, behind your own domain.
