Secret/hidden internal pages exist across Chromium-based browsers and are accessed with `chrome://` (Chrome/Brave) or `edge://` (Microsoft Edge). These pages expose diagnostics, experiments, performance tools, and troubleshooting utilities that aren't always visible in standard settings.



> **Authoritative Lists:**  

> - Chrome/Brave: `chrome://chrome-urls` (alias: `chrome://about`)  

> - Edge: `edge://edge-urls`

## Legend / Notes



- **[Stable]**: Generally available in current desktop builds.

- **[Legacy]**: Still present, but tied to features being deprecated.

- **[Build/Flag-gated]**: May require a specific OS/build/channel or a feature flag; may be hidden by enterprise policy.

- **[Deprecated]**: Removed or non-functional in current Chrome; keep for historical context with a pointer to replacements.



> ⚠️ **Enterprise**: Admin policies can hide or disable some internal URLs.  

> 🧭 **Per-version variability**: Items can move, be renamed, or vanish between releases. Always verify on your installed version via `chrome://chrome-urls` / `edge://edge-urls`.

## Quick Updates Since 2023



- **New:** `chrome://settings/performance` (Memory Saver modes, performance alerts).  

- **New-ish:** `chrome://privacy-sandbox-internals` (diagnostics for Privacy Sandbox features).  

- **Clarified:** `chrome://site-engagement` description (engagement scores influence certain heuristics like autoplay).  

- **GCM → FCM:** `chrome://gcm-internals` now references Firebase Cloud Messaging.  

- **Deprecated:** `chrome://net-internals` (use `chrome://net-export` + DevTools Network).

---



## Notes for Edge & Brave



- **Microsoft Edge**: `edge://edge-urls` lists internal pages. Many `edge://…` pages mirror Chrome’s (`flags`, `gpu`, `net-export`, etc.). Some legacy pages like `edge://net-internals` may still exist but are in the same deprecation path as Chrome’s.  

- **Brave**: Use `brave://chrome-urls`. The list often displays `chrome://` links but they map to Brave’s internals.



---



## Chrome Apps Deprecation (Context for “Legacy” rows)



Chrome Apps are being phased out: deprecation phases began in 2025 with **end-of-life in 2028** (on managed ChromeOS timelines). Keep `chrome://apps` / `chrome://app-service-internals` rows labeled **[Legacy]**; they’re largely irrelevant off-ChromeOS and will diminish over time.



---



## Handy Dev Workflows



- **Network debugging (modern):**  

  1) Live capture in **DevTools → Network**  

  2) Long-running or background capture: **`chrome://net-export`** → save NetLog → open in NetLog Viewer.  

- **Performance investigations:**  

  - **`chrome://settings/performance`** to tune Memory Saver modes and set always-active site exceptions.  

  - **`chrome://tracing`** (when available) for low-level traces; or use DevTools Performance panel.
