Everything you need. Nothing you don't.
No dashboards to learn. No tiers to upgrade. Just reliable monitoring that lives on your machine.
Real-time status, no refresh
Each site is pinged on its own interval. The status dot updates the moment something changes - no refresh, no polling the page, no clicking around.
Multi-channel alerts
Popup, email, webhook, Telegram, or run a local app. Toggle independently. Mix and match.
Local-first
All data stays on your machine. No account, no cloud, no telemetry - ever.
Advanced HTTP
Any verb, custom headers and body, basic auth, expected status codes, follow-redirects toggle, per-site timeouts.
Instant
Native Windows app, not Electron. Tiny install, instant startup, near-zero memory footprint.
Uptime history
Every status transition is recorded so future charts can show per-site and global uptime over time.
Local status page
Opt-in HTTP server exposes a localhost status page with live auto-refresh. Password-protect it if you like.
Free, forever
No paid tier, no trial countdown, no upsell. The whole thing is free.
Your watchlist, in your AI assistant.
Ask Claude, Cursor or VS Code which sites are down, what changed overnight and how long it was out. UpWatchr answers from its own history - and, once you allow it, adds, pauses or re-checks sites for you.
- Off until you turn it on, and read-only until you allow more.
- Removing a site always asks you in UpWatchr first.
- API keys, passwords and bot tokens are never shared with the assistant.
- One-click setup for Claude Desktop, Cursor, VS Code, Windsurf and Gemini CLI.
What went down while I was asleep?
Two things. staging-api was offline from 03:12 to 03:40 - 28 minutes of 502s. The NAS admin panel timed out twice and recovered both times. Everything else stayed up.
Check staging-api now.
It's back: 200 OK in 184 ms.
Notify me - but only how I want.
Every channel is independent. Want a Telegram nudge plus a desktop popup? Done. Want webhook-only with no popups? Done.
Popup
Native Windows toast with site name, URL, HTTP code, and latency.
Gmail, Outlook, or any SMTP server. Rich HTML body with the full request context.
Webhook
POST JSON or GET querystring with siteId, method, status code, latency, and error.
Telegram
Paste a bot token, hit Connect, done. Chat ID is auto-detected.
Local app
Run a script or executable with siteId, status, HTTP code, latency as args.

Your watchlist, in a browser.
Flip a toggle in settings and UpWatchr starts a tiny HTTP server on localhost. Open the URL in any browser to see the live status of every site you're monitoring. Matches your desktop theme.
