Uptime Monitor – Keep Tabs Responsive

Keep selected tabs responsive with auto‑recovery when pages freeze or stall. All local, no account, no tracking.

Monitor only the pages that matter and keep them responsive — automatically, locally, and under your control. 💡 Why Uptime Monitor? Long-running web apps — AI chat tools, dashboards, and internal tools — can freeze or stop responding after a while. You reload, lose context (or unsent input), and repeat the same routine several times a day. Uptime Monitor quietly watches only the pages you explicitly opt in to and steps in when they stall. It can reload the page or, when enabled and appropriate, restart the tab for a clean recovery. This is a browser tab/page monitor, not a server uptime checker. Great for: - AI chat tools that tend to freeze or stop responding - Analytics dashboards (GA, Looker Studio, internal BI tools) - Admin panels and internal web apps that need to stay usable - Any page you can’t afford to get stuck or unresponsive 🟢 Key features Opt-in URL monitoring (no “watch everything”) Add only the pages you care about. Uptime Monitor never monitors other sites or pages you didn’t add. Automatic recovery (reload or tab restart) When a monitored page stalls, Uptime Monitor can recover it by reloading the tab. For stubborn cases, you can enable a stronger “tab restart” recovery (close + reopen). Site adapters (supported sites only) Some sites can use tailored detection and recovery defaults via an adapter. Currently, Uptime Monitor includes an adapter optimized for ChatGPT (chatgpt.com / chat.openai.com), with token-stall detection and a restart-focused recovery style. All other sites use a safe, generic baseline. Profiles per site Choose a built-in profile: - Safe (recommended) - Standard - Fast recovery (may interrupt long-running tasks) Or fine-tune thresholds and behavior per site to match how sensitive the page is. Designed to reduce false recoveries - Typing guard (avoids recovering while you’re actively typing) - Degraded-state detection (captcha / login / rate-limit screens) to avoid making things worse Privacy-first design No account, no login, no tracking. All settings and recent recovery logs are stored locally in your browser. Lightweight and focused Runs quietly with minimal overhead. Control everything from the Settings page and the right-click menu: “Keep this page responsive”. ⚙️ How it works 1. Open a page you care about (an AI chat tool, a dashboard, an admin panel, etc.). 2. Right-click and choose “Keep this page responsive”. 3. Uptime Monitor asks for the minimal permissions required (monitoring + access for that site) and adds the page to your monitored list. 4. If the page becomes unresponsive, Uptime Monitor recovers it automatically based on your selected profile and recovery method. You can review recent recoveries, adjust profiles, switch recovery methods, or remove sites at any time from the Settings page. 🔒 Permissions & privacy Uptime Monitor starts with no broad website access. It requests additional permissions only when you explicitly choose to monitor a site. Important note about Chrome’s permission wording: - Chrome may label the optional “Tabs” permission as “Read your browsing history”. Uptime Monitor uses this only to identify and manage the specific monitored tabs (matching your monitored URLs, observing navigation changes, and performing the recovery action you selected). It does not scan, store, or sell your general browsing history. Site access (optional, per-site): - When you add a site, Chrome asks you to grant access only to that site (e.g., https://example.com/*), not your entire browsing. - This access is used to run a small local helper on the monitored page to detect responsiveness signals (such as recent page activity, typing activity, and simple heuristics like captcha / login / rate-limit states), and to perform the recovery actions you enabled (reload or restart). All monitoring happens locally. No browsing data, prompts, or page content are uploaded or sent to a server. You can revoke site access at any time in Chrome’s extension settings, or simply remove the site from the monitored list. ❤️ Support development Uptime Monitor is completely free and works without registration. If it has rescued a stuck tab or saved you time, you can say thanks with a small tip via the optional “Buy me a coffee” link in Settings. It genuinely helps future improvements. 📝 Notes & attribution Uptime Monitor is an independent tool and is not affiliated with or endorsed by OpenAI or any other service provider.
