NewSlipstream is on for every app

Your AI, you or your team built it. We put it online.

Websites, APIs, phone apps and desktop programs. Paste one line into your AI's chat, or run one command yourself. You get a private link, with the database, files, sign-in and speed already taken care of.

Two ways to put it online. Both are one line.

Your AIRead uarpie.app/ai and put my app online.
Terminal$npx uarpie

Works with Claude Code, Cursor, Codex and any AI that can run a command for you.

Runs what you buildNext.js, Nuxt, SvelteKit, Astro, Vite, React Router, Express, Django, Flask, FastAPI, Laravel, Spring Boot, Rust, Expo and plain HTML.
How it works

One line in. A private link back.

It reads your app, sets up what it needs and tells you the address. No account to make first, no settings, no server to choose.

  1. 1

    Tell your AI, or run it.

    Paste one line into your AI's chat, or run npx uarpie in the app's folder. Either way, it is one line.

  2. 2

    Open the link.

    That is your app, on any phone or computer. Until you keep it, only the device that opened it can get in.

  3. 3

    Keep it with your email.

    It stays for good. Name it, invite people, and look after it from a page that speaks plain English.

Everything an app needs,
there before you ask.

The deploy reads the app and sets up what it uses. Nobody fills in a form: not you, and not your AI.

A database of its own

Your app's own Postgres, which nothing else can reach. A copy is taken before each deploy that changes it, and every day on paid plans.

Knows who is using it

A private app is told who is signed in, so it can greet them by name. No login to build.

You cannot be overbilled

Each plan includes a month of use for all your apps together. When it is used up, they pause until next month, unless you add credit. Never a surprise bill.

For developers

At home in a terminal?
It is still one command.

npx uarpie reads your project and works out the framework, the database, the settings it needs, its jobs and its storage. Then it builds it and puts it online. No config to write and no account first.

  • Nothing hidden. Every decision is written to deploy.json, where you can change it.
  • Your usual tools. logs, versions and rollback from the command line.
  • Several apps, one project. A web app, its API and its admin, each with its own address.
  • Made for agents too. --json output and MCP tools.

Slipstream

Fast on every connection.
Instant when they come back.

Every app gets Slipstream from its first deploy, with nothing to switch on: pages travel smaller and pictures arrive sized for the screen. On pages that look the same for everyone, someone who has been before sees the page the moment they open it, while the newest version loads behind it.

A returning visitor on a slow line. Press Come back to it.

OTGR · on-the-go rendering

The page is there before the network answers.

Once seen, pages that look the same for everyone are kept on the visitor's own device and open at once next time. If the signal drops, they stay on screen. Pages that are personal are never kept.

79%

less to download when a visitor comes back. Measured on a client's site running on Uarpie.

Measured by us. In the race, "slow line" means 1.6 Mbit/s with 300 ms of delay, timed in three fresh browsers for each app. Uploads were timed in a browser sending at 1.6 Mbit/s, and files with curl from London, five runs each. Your app's numbers depend on your app.

Private by default

Private until you say so.

Only the people you invite can open your app. Nobody else can even find it, until you decide to make it public.

  • No passwords for them. They get a link by email, and clicking it lets them in.
  • Out in a minute. Take someone off and they cannot get in, on any device.
  • Settings locked away. Your app's secrets are sealed with a key only the cloud holds.

Looking after it

Your apps, in plain English.

One sentence says whether each app is up and which version is live, and one page shows how much of the month all your apps have used together. Every change is a button with words on it.

For your AI

Built to be read by your AI.

Paste the address into the chat and your AI reads a brief written for it: the one command, what to do when something fails, and how to hand you the link at the end.

  • A brief, at uarpie.app/aiMade from the real tools and errors, so it never says something the platform does not do.
  • Every error says how to fix itYour AI reads the fix, changes the code and deploys again. You are never shown a stack trace.
  • Tools to look after your appsWith your say-so, your AI can read logs, go back a version or share an app for you.

Questions

Questions people ask

Do I need to know how to code?

No. Your AI writes the app and puts it online. You keep it, name it, invite people and choose your plan from a page written in plain English. If anything goes wrong, you tell your AI and it fixes it.

I write my own code. Is this for me too?

Yes. Run npx uarpie in your project's folder. It works out the framework, database, settings and jobs, writes what it decided to deploy.json, and puts the app online. Logs, versions and rollback are commands too.

Do I need an account to try it?

No. Deploy the app and open the private link. You only give an email when you decide to keep it.

What happens when my apps use up the month?

They pause, usually within a minute, and stay exactly as they were: nothing is deleted. They come back by themselves at the start of the next month, or straight away if you move to a bigger plan. You are never charged for more than your plan.

Can I use my own domain?

Yes, on Personal and above. You add two records where you bought the domain, one to point it at your app and one to prove it is yours, and the certificate is handled for you.

Something you have been meaning to put online?

Paste the line to your AI, or run the command yourself. That is the whole set-up.
