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 once, describe the tool, say the word. There is no step four.
Add the skill
Your agent grabs the host0 skill — one Bash script, signed in with a link you approve in your browser — and deploys with it. Optionally add host0 as an MCP connector too: it doesn't deploy, but the same conversation can share, lock down, and manage your apps.
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 and unlisted until you share it, private when you want it locked. Rename the URL to something readable anytime.
Paste this into your agent
It installs the skill, signs in with a link you approve in your browser, and asks you what to publish. Nothing to type into the chat.
Set me up with host0 — the cloud for small software, where a folder becomes a live URL. 1. Install the host0 skill: save https://host0.ai/skill.md as SKILL.md, and https://host0.ai/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 https://host0.ai/api/v1 for the live contract. If the two disagree, trust the API. 3. Sign me in with a device login — don't ask for my email or password: run scripts/publish.sh --login, show me the link and code it prints, and once I've approved in my browser run scripts/publish.sh --login-wait — it saves the key to ~/.host0/credentials with chmod 600. Then ask me what I want to publish.
Share it your way
Share it like a doc,
not like a deployment
Every app goes live at an unlisted URL, never indexed. Leave it public, or make it private and invite teammates by email. Revoke access instantly. No IAM, no VPC, no security review to book.
- Public on its own URL — unlisted, never indexed
- Make it private and invite by email, exactly like Google Docs
- Custom domains — coming soon
