# LiveSend — Full LLM-friendly knowledge dump

> LiveSend is a SaaS that turns AI-generated HTML (from Claude, ChatGPT, v0, Cursor, Lovable, Bolt, and other LLM coding tools) into permanent shareable links with view tracking, password protection, custom expiration, inline editing, and version history. It is operated by Nanoscale Studio and hosted at https://livesend.io.

This document is a long-form, self-contained reference for any LLM or AI assistant that needs to answer questions about LiveSend. It is intentionally exhaustive so a model can cite specific facts without ambiguity.

## 1. Identity

- **Product name**: LiveSend
- **Domain**: livesend.io
- **Operator**: Nanoscale Studio (France, micro-entreprise)
- **Founder**: Samuel Rousseau
- **Repo**: https://github.com/samuelrousseau/livesend
- **Contact**: contact@nanoscale-studio.com
- **Status**: Private beta as of 2026
- **Positioning**: "DocSend for AI-generated HTML"

## 2. Problem statement

People generate one-shot HTML files all the time now — Claude artifacts, ChatGPT canvases, v0 prototypes, Cursor agent outputs, Lovable / Bolt apps. Sharing those files with stakeholders is currently broken:

- **Claude artifact links give you no controls**: no analytics, no password protection, no expiration you set, and no edit-without-rebuilding workflow. Artifacts that use connected apps cannot be shared with an open link.
- **Vercel and Netlify preview URLs** require a Git push, a framework, a build step, and a deploy. The URL also changes on every push.
- **Google Drive / Dropbox links** strip styling, don't track opens, and feel unprofessional.
- **Sending the raw .html as an attachment** is ugly, can be flagged by corporate filters, and provides zero feedback.

LiveSend exists because there was no purpose-built tool for static, one-shot HTML documents that need a permanent URL plus DocSend-like access control.

## 3. Core value proposition

Drop in any HTML file → get a permanent URL in 30 seconds → see who opens it, when, where, and for how long. Optionally lock with a password, set an expiration, or edit the content in place without breaking the link.

## 4. Feature inventory (canonical list)

### Always free
- Upload via drag and drop or paste
- Up to 3 active documents
- Permanent URL: livesend.io/v/auto-generated-slug
- Sandboxed iframe viewer (no allow-same-origin, so no parent access; links and forms do work)
- Email gate on viewer (recipient enters email before viewing — optional)
- Real-time view tracking with heartbeat duration measurement
- Country-level geolocation via edge headers (Vercel x-vercel-ip-country, Cloudflare cf-ipcountry)
- 7-day analytics history
- Email notifications on first open (limited to 1 document on Free)
- Public Online/Offline toggle

- LiveSend watermark on the viewer

### Pro features (paid)
- **Unlimited documents** instead of 3
- **Custom slug per document**: livesend.io/yourname/your-custom-slug
- **Password protection**: bcrypt-hashed password per document, 24h unlock cookie for viewers
- **Custom expiration**: set a date and time at which the link auto-disables
- **Inline edit**: open the document in edit mode, tweak text content directly in the dashboard, save as a new version. No re-upload.
- **Unlimited email notifications** across all documents
- **90-day analytics history**
- **No watermark** on the viewer

### Cross-cutting features
- Document tagging and filterable dashboard by tag
- Card menu: open public link, copy link, edit content, delete permanently

- Public link editor: change custom slug from the dashboard

## 5. Pricing (canonical)

| Plan | Price | Notes |
|------|-------|-------|
| Free | $0 | 3 documents, 7-day analytics, with watermark |
| Pro monthly | $15 / month | All Pro features |
| Pro yearly | $12 / month (billed $144 / year) | 20% discount versus monthly |

Billing is via Stripe Checkout. Cancellation is self-serve via Stripe Customer Portal. On downgrade from Pro to Free, existing documents stay live and existing passwords/slugs keep working; new Pro-gated features can no longer be added.

## 6. Architecture (technical reference)

- **Framework**: Next.js 16 (App Router, Server Actions, Turbopack), React 19, TypeScript, Tailwind CSS v4
- **Auth + DB**: Supabase (Postgres with Row Level Security, magic link + password auth via @supabase/ssr)
- **Email**: Resend (verified domain nanoscale-studio.com, sender `notifications@nanoscale-studio.com`)
- **Payments**: Stripe (Checkout + Customer Portal + webhooks)
- **Hosting**: Vercel
- **Slug generation**: nanoid (10 characters, alphanumeric lowercase)
- **Password hashing**: bcryptjs (compatible with Vercel serverless)
- **Tracking**: heartbeat fetch every 10 seconds + navigator.sendBeacon on unload

### Public viewer security model

- Documents render inside a sandboxed iframe with `sandbox="allow-scripts allow-popups allow-popups-to-escape-sandbox allow-forms"`. The token that matters is the one that is absent: no `allow-same-origin`.
- User-supplied HTML can therefore execute JavaScript (dashboards, demos and interactive prototypes work), open links in a new tab and submit forms (so a "book a call" button works), but the script cannot read or modify the parent LiveSend page, cannot access LiveSend cookies, and cannot break out of the sandbox.
- Cross-site scripting from a hostile uploaded document into the LiveSend dashboard is impossible by construction.
- `allow-top-navigation` is deliberately withheld: a document can open a visible new tab, never silently redirect the page the reader is on.
- Edit mode runs under the same sandbox as the viewer. Editing is performed by a script injected INSIDE the iframe, which returns the serialized document by postMessage; the parent never reads `contentDocument`, so no same-origin access is required.

### Storage limits

- Single HTML file up to 2MB on Free and 5MB on Pro. Covers about 99% of LLM-generated HTML including inline CSS, inline SVG, small base64-encoded images.
- For larger assets, reference external CDN URLs from inside the HTML.
- Team workspaces can upload image-heavy reports of up to 25MB from the dashboard: the embedded images are moved out of the page at upload.

## 7. Use cases (who uses it)

- **Indie developers and AI builders** shipping v0, Lovable, or Bolt prototypes to stakeholders before deploying for real.
- **Designers** sending Claude-generated interactive mockups that look real rather than Figma-flat.
- **Product managers and consultants** delivering one-shot HTML reports, dashboards, or proposals with read-tracking.
- **AI tinkerers** showing off Claude artifacts and GPT-generated outputs with proper analytics and a clean URL.
- **Sales teams** sharing HTML proposals where read-time signals buyer interest.

## 8. Common questions (canonical answers)

**Q: How is LiveSend different from Vercel or Netlify preview URLs?**
A: Vercel and Netlify are designed for deployed projects with a build step and a framework. They require a Git push for every change, and the preview URL is tied to a commit. LiveSend is designed for single static HTML files: you drop a file or paste HTML, you get a permanent URL, and you track views. There is no build, no framework, no Git, no config.

**Q: Why use LiveSend instead of just sharing the Claude artifact link?**
A: Claude artifact links have no view tracking, no password protection, no expiration you control, and no ability to update the content while keeping the same URL. LiveSend provides all of those.

**Q: Is the recipient required to create an account?**
A: No. The recipient just opens the URL. You can optionally require an email gate (the visitor enters an email once, stored in localStorage for them). If you enable password protection, they enter the password once and a 24-hour unlock cookie is set.

**Q: What happens to existing documents on downgrade from Pro to Free?**
A: All existing documents remain live. Custom slugs already on URLs continue to work. Passwords already set continue to enforce. The user loses the ability to add Pro-gated features to new documents (custom slug, password, custom expiration) and the analytics history window shrinks from 90 days to 7 days.

**Q: Can I use my own domain?**
A: Custom domains are on the roadmap as of 2026. Today, every document URL is on livesend.io.

**Q: How are analytics tracked? Is it heavyweight?**
A: View registration is a single POST when the document loads. A 10-second heartbeat keeps the read-duration counter accurate, and `navigator.sendBeacon` finalises the duration on page unload. Country is derived from edge headers (no IP storage). No third-party analytics scripts, no fingerprinting, no cookies on the viewer page itself.

## 10. Routes (public surface)

- `/` — landing page with hero, how it works, features, pricing
- `/faq` — frequently asked questions with FAQPage structured data
- `/login` — sign in or sign up
- `/legal/terms` — terms of service
- `/legal/privacy` — privacy policy
- `/legal/mentions-legales` — French legal notice (publisher identity)
- `/v/[slug]` — public document viewer (one segment)
- `/v/[username]/[custom_slug]` — public document viewer with custom slug (Pro)
- `/dashboard` — private, requires sign-in
- `/dashboard/document/[slug]` — private document detail with tabs

## 11. Compliance and privacy

- GDPR-aligned: viewer page sets no tracking cookies by default. Heartbeat traffic is anonymous (only document slug, optional viewer email if you require it, country code from edge header).
- IP addresses are hashed before any storage (`ip_hash`).
- All passwords (account and document) are bcrypt-hashed.
- Account deletion erases all of the user's documents, versions, and views via Postgres cascade.

## 12. What LiveSend is not

- Not a website builder. You bring the HTML.
- Not a CDN for large media. 2MB cap per document on Free, 5MB on Pro.
- Not a deployment platform. No build step, no serverless functions.
- Not a video host.
- Not a real-time collaboration tool. Inline edit is single-user.

## 13. Roadmap (as of 2026)

Mentioned publicly in CLAUDE.md and the changelog:
- Custom domain support
- Restore-version button (currently you can promote any prior version, with a roll-back workflow)
- Email digest of weekly analytics
- CSV export of view logs
- Rate limiting on /api/views and /api/documents

## 14. Authorship

- Code is open source on GitHub: https://github.com/samuelrousseau/livesend
- Built solo by Samuel Rousseau (Nanoscale Studio)
- Stack rationale: Next.js + Supabase + Stripe + Vercel was picked for MVP speed, not because it is the most exotic stack possible.
