Show HN: Valet – Self-Hosted Cloud Agents with Computers

self-hosted cursor cloud agents / amp orbs / etc

• linux server or mac with docker engine 24+ and compose v2
• claude/codex sub or anthropic/openai api key
• github token for private repositories and pull requests (optional)

git clone https://github.com/dropalltables/valet
cd valet
cp .env.example .env   # set POSTGRES_PASSWORD, VALET_SECRET_KEY (openssl rand -base64 32), VALET_PASSWORD
docker compose --profile sandbox build
docker compose up -d --build

open http://localhost:3000 and add accounts under settings: a claude setup-token, a codex sign-in or api key, a github token. every env var is documented in .env.example.

on a domain: reverse proxy port 3000 with websockets, set VALET_BASE_URL, and point *.valet.example.com at the box with a wildcard cert. services live on those subdomains.

1. docker compose resource from this repo. leave the domain field empty
2. env: VALET_BASE_URL ,VALET_SERVICE_DOMAIN ,VALET_PROXY_NETWORK (the app's uuid),VALET_CERT_RESOLVER (a dns-challenge resolver you add to the proxy config)
3. turn off "escape special characters in labels"

• .valet/setup : runs once after clone
• .valet/resume : runs on every wake
• .valet/services.yaml : processes to keep running

services:
  web:
    command: npm run dev -- --port $PORT
    browser: true     # shows in the services tab
    health: /
  api:
    command: uv run uvicorn app:app --port $PORT
    port: 8000        # default: assigned

inside the sandbox: valet service start|list|logs|restart|remove, valet url <port>.

bun install && docker compose up -d db
VALET_DOCKER_NETWORK=valet_valet VALET_REPOS_VOLUME=valet_repos bun run dev:core
bun run dev:web

core holds the docker socket; only web publishes a port. agents have sudo in their container, so treat a sandbox as untrusted beyond its repo. on cloud hosts block metadata: iptables -I DOCKER-USER -d 169.254.169.254/32 -j DROP.
