What Pharos is

Updated 2026-09-08 · Pharos 0.5.10

Pharos is a self-hosted status page that runs its own checks. It polls HTTP endpoints and TCP ports, listens for heartbeats from jobs it cannot see from outside, and sets component status without anyone pressing a button. A failing check opens an incident and posts the first update; a recovered check closes it and posts the closing update. It speaks the Cachet 2.x API shape on purpose, so scripts written against Cachet keep reading it unchanged.

Pharos public status page showing overall status, a 90-day uptime bar, three services and two incidents — **The public status page.** Overall headline, a 90-day uptime bar, services with their components, and incidents grouped by day. Every section is a switch you control — the data here is a demo.

PHP	8.3 or newer
Database	SQLite (default) or MySQL
Extensions	`pdo_sqlite` (plus `pdo_mysql` for MySQL), `mbstring`, `openssl`, `sodium`, `zip`, `curl`, `fileinfo`, `tokenizer`, `xml`, `ctype`, `json` — the installers check every one before writing anything. HTTP checks need `allow_url_fopen` on.
Web server	Serve only the public files. The web installer copies them into the existing document root; SSH/manual installs point the root at `public/`. Apache needs `mod_rewrite`; nginx needs equivalent routing.
Runs on	A compatible host with PHP 8.3+, required extensions, writable storage, outbound HTTPS and cron — cPanel, DirectAdmin, Plesk or a plain VPS — or Docker

A health endpoint is available at /up.
