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.
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.
Read uarpie.app/ai and put my app online.$npx uarpieWorks with Claude Code, Cursor, Codex and any AI that can run a command for you.
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.
Paste one line into your AI's chat, or run npx uarpie in the app's folder. Either way, it is one line.
That is your app, on any phone or computer. Until you keep it, only the device that opened it can get in.
It stays for good. Name it, invite people, and look after it from a page that speaks plain English.
Reading uarpie.app/ai. Putting it online now.
It is online. Open this on the phone or computer you will use it from:

Put online what you have made, and offer it in other languages. Soon, build something new and open it on your phone.
One command puts your app online, private from the first minute and fast on every connection.
About hostingAn app for your computer. Say what you want, watch it being made, and put it online with one button.
About BuilderOpen any phone app on Uarpie by its code. It runs full screen, like any app on your phone.
About the appOffer your site in up to 30 languages. Nobody sees a word until you have read it.
About languagesThe deploy reads the app and sets up what it uses. Nobody fills in a form: not you, and not your AI.
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.
Uploads large and small, kept safe and handed out from the edge nearest each visitor.
A private app is told who is signed in, so it can greet them by name. No login to build.
Each update is a new version, and the last ten are kept ready. Going back is one click, and nothing is rebuilt. Try it.
Use a domain you own, on any paid plan. The certificate is done for you.
Offer your site in up to 30 languages. You read every translation before anybody else sees it.
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.
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.
deploy.json, where you can change it.logs, versions and rollback from the command line.--json output and MCP tools.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.
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.
less to download when a visitor comes back. Measured on a client's site running on Uarpie.
quicker uploads on a slow line. Pages squeeze what they send.
830 ms became 217 msquicker files and photos, sent from the edge nearest the visitor.
859 ms became 123 ms, from LondonMeasured 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.
Only the people you invite can open your app. Nobody else can even find it, until you decide to make it public.
Try it: invite someone, or take Sam off.
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.
Three apps. All of them are fine.
A sketch of the dashboard. Press an app and a decision rises as a sheet.
Starting from nothing? Soon, Uarpie Builder will make one from your own words.

Their app is theirs. Nothing of ours is on it.
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.

Try it. One app, kept for as long as you use it.
Your own apps, online for good, on your own web address.
More room for the apps a household shares.
For a club, a school or a small business, with room for real traffic.
Slipstream, private links, versions, a database and email support are on every plan. Compare the plans
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.
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.
No. Deploy the app and open the private link. You only give an email when you decide to keep it.
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.
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.
Paste the line to your AI, or run the command yourself. That is the whole set-up.
