The documentation, readable before you buy

These are the exact files that ship in the repository. Published here so you can estimate the real cost of owning Vigil (deploying, upgrading, customizing) before spending a cent. What you read is what you get.

• Quick start, git clone to running instance in ~10 minutes
• Migration, importing the monitors you already have from fifteen monitoring systems, and what a move does not carry
• Deployment, production setup, env vars, reverse proxy, backups
• Upgrades, taking updates after you've customized the code
• Customization, rebranding and extending, upgrade-safely
• Security, the recovery safety model, SSRF posture, hardening & disclosure
• Notifications, 25 native provider types on one durable pipeline - Slack, PagerDuty, Jira Service Management, Matrix, Twilio, Web Push, Amazon SNS and the rest - plus a bridge to an Apprise server you run
• Remote probes and quorum, checks run from machines you own, and why a probe that did not answer is never a failure. The four outcomes it produces are recorded from a real run
• Changelog, every release, documented

Also public: the full license text, the architecture, and a click-through demo of the running app.
