For apps you build with Claude & ChatGPT

Three promises
Three things nobody else will promise you.
Add people once. You pick who sees what.
Add the people you trust once — staff, family, friends. Then choose who can open which apps: some shared with everyone, some just for you. Croft handles the sign-in, so there's no login page to build and no passwords to manage. Someone leaves? Remove them once and they're out of everything.
You own the ground it stands on.
Every croft is a real private server with your name on it. Your apps and your data live there — not in someone's shared cloud. Want to leave someday? Take it all with you — every app, its data, and its code. It was always yours.
One flat price. No credit anxiety.
Croft charges for the ground, not the ideas. Build one app or 15 — the price doesn't move. The AI is your own Claude or ChatGPT subscription, so there are no tokens, no credits, and no surprise bill because you prompted too enthusiastically on a Tuesday.
On purpose
Built small on purpose.
Croft apps top out at the number of people you actually know. That's not a limitation we're working on — it's the whole idea. Because your apps will never need to "scale", they can live on a small server that doesnt cost a lot to run. The price stays flat forever. Nothing is public unless you make it public. And your software can be exactly as scrappy, personal, and particular as your business is.
Building the next Airbnb? Genuinely, sincerely: we are not for you. There are excellent tools for that. Croft is for the software in between — the financial model, the quote calculator, the plant database, the thing you currently do in a spreadsheet that deserves better.
How it works
From idea to "here's the link" in one conversation.
Get your croft.
Sign up, pick a name. Two minutes later your private server exists, with your login page and your empty apps list.
Connect Claude.
Paste one link into Claude's settings. Now Claude can build straight onto your croft — from the app, your desktop, or your phone. How to connect
Describe the app.
"Build me a cash-flow forecast the three of us can update." Claude writes it, deploys it, and hands you the link — live, HTTPS, behind your login.
Invite your people.
Add them by email. They tap the link, sign in with a passkey (no password to forget), and they're in. Add someone once, then pick which apps they can open.
Examples
Small software, real work.
The platform
You build the apps. Croft is the platform they run on.
Croft isn't a software company — it's the hosting and single sign-on your AI-built apps run on. The unglamorous, essential parts — security, logins, backups, rollbacks — handled for you, so a clever prototype becomes software you can actually rely on.
Security, built in
Every app sits behind your login before a single line of its code runs — it can't ship a broken login page, because it doesn't contain one. HTTPS everywhere, passkeys instead of passwords, updates applied for you.
One login for everyone
Add your people once. They sign in with a passkey — nothing to remember — and every app they're allowed to use already knows who they are. No per-app accounts, no password resets.
You decide who sees what
Share some apps with everyone, keep others just for you. Access is yours to set, app by app. Someone leaves? Remove them once and they're out of everything, instantly.
Backups you can count on
Every app's data is backed up continuously to separate storage — and we practise restoring it. A backup nobody has tested is just a hope, so we test ours.
Roll back in one click
An update from your AI not right? Put any app back the way it was a moment ago with a single click. Every deploy is reversible — nothing stays broken.
Your AI can fix its own bugs
When something breaks, Croft gives Claude or ChatGPT the tools to read the app's logs on your croft, find the bug it wrote, fix it, and redeploy — often before you've noticed.
Stake out your croft.
Your team's first app could be live before lunch.
