the cloud for small software.
bring any coding agent. build the tool only your team needs — a tracker, a dashboard, a tiny internal app. then just say "deploy to host0". live in seconds, public at an unguessable url. lock it down like a doc when you want.

agents made it trivial to build software for one person or one team. deploying and sharing it is still stuck in the big-cloud era. host0 deletes that complexity — small software should be as easy to share as a google doc.
// how it works
from prompt to production in one sentence
connect
claude and mcp clients add host0 as a connector — one url, one login. every other agent with a shell grabs the host0 skill: one bash script plus an api key from an email code.
build
describe the tool you wish existed. your agent writes it right there — no repo, no build pipeline, no yaml.
deploy
say “deploy to host0”. your app is live on its own url in seconds — public at an unguessable slug until you share it, private when you want it locked.
paste this into your agent
it installs the skill, gets its own api key, and asks you what to publish. no account setup in a browser first.
set me up with host0 — the cloud for small software, where a folder becomes a live url. 1. install the host0 skill: save http://localhost:3000/skill.md as SKILL.md, and http://localhost:3000/publish.sh as scripts/publish.sh beside it, then chmod +x scripts/publish.sh. in claude code that folder is ~/.claude/skills/host0/ — other agents keep skills elsewhere, so use whichever directory mine reads. 2. read SKILL.md, then curl http://localhost:3000/api/v1 for the live contract. if the two disagree, trust the api. 3. get me an api key without making me run commands: ask for my email, POST it to http://localhost:3000/api/v1/auth/request-code, ask me for the 6-digit code host0 emails me, POST that to http://localhost:3000/api/v1/auth/verify-code, and save the returned key to ~/.host0/credentials with chmod 600. then ask me what i want to publish.
// small software
purpose-built. one team. zero compromise.
not every problem deserves a saas subscription. some deserve twenty minutes with an agent and a url of their own.
standup tracker
async standups that match how your team actually works.
kpi dashboard
the five numbers your team cares about. nothing else.
sprint board
your process, your columns — not what a pm tool decided.
on-call rota
who's on call, who's next, and one button to swap.
invoice mini-app
generate branded invoices from a form. for a company of one.
offsite rsvp
a one-page rsvp with dietary picks. alive for exactly one event.
// share it your way
share it like a doc,
not like a deployment
every app goes live at an url only you know. leave it public and unlisted, or make it private and invite teammates by email. revoke access instantly. no iam, no vpc, no security review to book.
- ✓public on an unguessable url — unlisted, never indexed
- ✓make it private and invite by email, exactly like google docs
- ✓bring your own domain when it graduates
your next internal tool is one sentence away
we're onboarding the first builders now. grab a spot — invites go out in order.
