№ 01 — From vibe to live

Built an app with Claude?
Share it.

You made something with AI, now it’s stuck on your screen. Backlit puts it on a live link with sign-in and saved data, set up by your assistant in the same chat. No servers, no setup. The AI builds it; Backlit hosts it.

Nothing AI runs in the live app. That’s what keeps it fast, private, and $2.50 a month.

Built for the apps you make with Claude ChatGPT

№ 02 — The moment

You built it. Now how do others use it?

It happens every time: the app works on your screen, and the next thing you ask is “how do I get this to the people who’ll actually use it?” That’s the wall: hosting, a login, somewhere to save the data. Backlit is the answer your assistant reaches for, without you leaving the chat.

For your people

  • A wedding game guests play to guess your future, with a digital guest book they leave a note in.
  • A personalised birthday game instead of a card.
  • A “how well do you know us” quiz for a couple, a trip, or the family pets.
  • A shared habit tracker where everyone sees only their own streaks.

For work

  • A client spreadsheet turned into a real app with sign-in.
  • A team noticeboard where staff post and everyone sees the same updates.
  • A price list or event schedule anyone can read but only you edit.
  • A contact or sign-up form that collects responses in one place.

№ 03 — How it works

Three steps to lit.

01
CONNECT
Point it at the MCP server
One URL, nothing to install. Now your assistant can publish for you, right in the chat.
mcp.backlit.run/mcp
02
BUILD
Build like you already do
Start fresh or bring an app you already made. Sign-in and saved data wire in as you talk.
ASSISTANT · BACKLIT

03
IGNITE
Get a link to share
Ask your assistant to publish. It goes live on its own link, with the right people on the allowlist.
→ bright-ledger.backlit.run

№ 04 — Starters

Not sure what to build? Choose a starter.

Pick a starter, tell your assistant to use it, and you get your own copy on a live link. Change the questions, the colours, the characters, or leave it exactly as it is.

№ 05 — The distinction

Built with AI, hosted by Backlit

Two different jobs. The AI builds your app; Backlit is the home it lives in once it’s built. Backlit isn’t another AI bolted into your app, thinking on every visit. Nothing AI runs in the live app. That’s what keeps it fast, private, durable, and $2.50 a month, not a per-visit AI bill.

№ 06 — Security

The hard part, handled

Apps built fast with AI keep getting hacked, almost always at the login. Backlit owns that part: sign-in, an allowlist, per-user data isolation, and private-by-default access are built into the platform, not left for you to hand-roll. You focus on the app; we’ve got the hard, risky bit covered.

№ 07 — Features

Everything a glow needs to shine.

LENS
Sign-in, handled
Magic link, Google, and Microsoft sign-in. Allow exact emails or a whole domain, with viewer, member, and admin roles. Private by default.
window.backlit.auth.user()
EMBER
Data that saves itself
Four stores, no backend: shared data everyone reads, a private per-user silo, a shared collection people can post to and read, and a write-only store for form captures. Region-pinned.
window.backlit.data.get(k)
ACCOUNTS
Public & Accounts glows
Open a glow to anyone with no sign-in, an anonymous session minted per visitor. Or switch on Accounts: still public, but visitors can register and sign in themselves, starting as a viewer.
auth_mode: public · accounts
DEPLOY
Deploy, or roll back
Every publish is an immutable version. Roll back to any prior version with one call. No downtime.
POST /v1/glows/{id}/rollback
REGIONS
Pinned where you put it
Served from Australia and the US. Your users’ data is pinned to one region and never crosses.
region: au · us
PRISM
A name of your own
Free glows get a friendly adjective-noun address. Paid plans unlock a custom subdomain or your own domain.
yourname.backlit.run

№ 08 — Your data, both ways

Put data in. Get it back out.

Your app saves data, and because it’s reachable through Backlit’s MCP, you can query it straight from Claude: ask for a summary, export it to a spreadsheet, or push it into Notion, in plain language. Most hosts hand you a database to query yourself. Backlit closes the loop. You own the HTML too, so nothing traps you: take the app and its data to another host whenever you like.

№ 09 — Pricing

Start free. Stay cheap.

Ship a private app for free on Spark. Brand it and grow your allowlist on Beam at $2.50/mo. Go public and scale on Flood. Add storage by the pack with Amp. Prices in USD.

For AI agents

Agents deploy without asking

Backlit is built for both surfaces. A documented MCP server and REST deploy API let AI agents discover the platform, create glows, push HTML, and manage allowlists, entirely on a user’s behalf. See the agent surface →
