ReviewSX

ReviewSX — share prototypes, get feedback fast

The 4 P's of product building: Prototype → Publish → Position → Procure feedback.

You built a prototype. Now the hard part: getting your boss, your client, or your team to actually look at it and tell you what they think — without making them clone a repo, run a dev server, or install anything.

ReviewSX turns any running prototype into a shareable link with a built-in feedback overlay. Reviewers open it in a browser, follow the guided tour you authored, and click any element to leave a pinned comment. You see every comment back in VS Code.

The 4 P's


🧩 Prototype	Build it however you like	Static HTML, React/Vite, Next.js — anything that runs in a browser
🚀 Publish	One click to a shareable link	GitHub Pages, or a live tunnel link for a quick "can you look at this?"
🎯 Position	Author a guided tour	Walk reviewers through exactly what to look at, in order
💬 Procure feedback	Pinned comments, back in your editor	Reviewers click elements to comment; you triage in the sidebar

Why it's different

Zero install for reviewers. They get a link. That's it. No account, no repo, no IDE.
Works on any device. Your reviewer can be on their phone in an airport.
In-context feedback. Comments are pinned to the actual UI element, not lost in a chat thread.
No style collisions. The overlay renders in a Shadow DOM — it never touches your prototype's CSS.

Who it's for

🚀 Startups & solo builders

You pushed a prototype to a public GitHub repo and it runs on localhost. Your boss is travelling and doesn't have VS Code. Publish to GitHub Pages, send the link, and feedback flows into the free hosted inbox — and into your sidebar.

🏢 Mid-market & enterprise

Private repo, busy reviewers who want a company-hosted link, real IP sensitivity. Self-host the ReviewSX inbox on your own AWS/Azure (Docker Compose, bring your own Postgres). Data never leaves your network; your reviewers just get a link.

Quick start

Open your prototype folder in VS Code.
Click the ReviewSX icon in the activity bar.
Start with overlay → your prototype opens in the browser with the toolbar.
Position: click the ⚙ gear to author a guided tour.
Publish: click Publish to GitHub Pages, or the broadcast icon to share a live tunnel link.
Procure: reviewer feedback appears in the sidebar, grouped by open / resolved.

Method	When	Reviewer sees
GitHub Pages	A stable link for async review	`username.github.io/repo` (needs a public repo, or GitHub Pro for private)
Tailscale Funnel / Cloudflare tunnel	A quick "look at this now" while it runs on your machine	A temporary public URL to your live localhost

Feedback inbox

Option	Best for
ReviewSX hosted inbox (free)	Indie builders & startups — `inbox.reviewsx.app`, each project isolated
Self-hosted	Enterprises — Docker Compose on your own infra, your own Postgres
Per-browser	Quick solo look — no inbox; feedback stays in the reviewer's browser

Configure via the Set up shared inbox button in the sidebar.

Commands

Command	What it does
`ReviewSX: Start prototype with overlay`	Serve the prototype with the overlay injected
`ReviewSX: Share via Tailscale Funnel`	Open a public URL to the running prototype
`ReviewSX: Publish to GitHub Pages`	Static-export + publish for async review
`ReviewSX: Set up shared inbox`	Choose hosted vs self-hosted feedback storage
`ReviewSX: Edit tour`	Author the guided walkthrough

Privacy & data

Your prototype's tour and your own local notes live in .protofeedback/ in your repo. The published copy embeds the tour so reviewers see it without an inbox, and those local files are never published.

Where reviewer feedback is stored depends on the inbox you choose:

Inbox	Where feedback lives
ReviewSX hosted (default, free)	On ReviewSX-operated servers (Fly.io), isolated per project by a unique key. Convenient, zero setup.
Self-hosted	Entirely on your own infrastructure (your AWS/Azure/Docker host + your Postgres). Nothing leaves your network. Best for private repos / IP-sensitive work.
No inbox	Only in the reviewer's own browser — it never leaves their machine (and never reaches you).

If you need full control over where reviewer feedback is stored, self-host the open-source inbox — see the repo's deploy/ folder.
