Uptime Monitor

Monitor specific URLs and auto-recover stalled pages — with site-aware actions like reload or close-and-reopen.

🌐 Uptime Monitor — Keep selected web pages responsive Keep selected web pages responsive — automatically, locally, and under your control. Uptime Monitor is a lightweight Chrome extension that helps you keep important browser tabs running smoothly. It watches only the pages you choose and automatically restores them if they freeze or stop responding. Everything runs locally in your browser — no data ever leaves your device. 🟢 Main features URL-based monitoring Select which websites or apps you want to keep active. Uptime never touches other tabs or pages. Automatic recovery Detects stalled pages and reloads them safely. Some sites, such as ChatGPT, can use tailored recovery (close-and-reopen) for better stability. Custom profiles per site Fine-tune how Uptime behaves for each domain — choose between “Safe,” “Standard,” or “Fast recovery” modes. Privacy-first design No account, no login, no tracking. All settings and logs are stored locally inside your browser. Lightweight & reliable Built to run quietly in the background with minimal resource use. Full control via an Options page and context-menu actions. 💡 How it works Open any page you want to keep responsive. Right-click and select “Monitor this URL.” Uptime adds the site to your monitored list and recovers it automatically if it freezes. You can review recovery logs, customize thresholds, or remove sites anytime from the Settings page. 🔒 Privacy-first permissions Uptime Monitor only requests access when you explicitly choose to monitor a site. It does not collect, transmit, or analyze your browsing history. All data, settings, and logs remain stored locally in your browser. Optional permissions are requested per site, and only when required for monitoring or recovery. This ensures full transparency and control over which sites are accessible. ❤️ Support development Uptime Monitor is completely free and works without registration. If you find it helpful, you can support future updates through an optional donation link in Settings. 📝 Notes & attribution Uptime Monitor is an independent tool and is not affiliated with or endorsed by OpenAI. “ChatGPT” is a trademark of OpenAI. All monitoring is performed locally; no chat content, prompts, or personal data are ever collected.
