Sieťový monitor zachytáva a zobrazuje každú sieťovú požiadavku vykonanú aktuálnou stránkou v reálnom čase.
Panel Network vo Chrome DevTools je výkonný, ale ťažkopádny — zaberá výrazný priestor na obrazovke, resetuje sa pri navigácii a núti vás odbočiť od obsahu stránky. Network Monitor poskytuje základné funkcie na sledovanie siete v ľahkom plávajúcom paneli, ktorý sedí priamo nad stránkou.
Zachytáva XHR a Fetch požiadavky a sleduje načítavanie zdrojov cez Performance API, pričom zobrazuje každú sieťovú požiadavku v reálnom čase. Pri každej požiadavke vidíte URL, HTTP metódu (GET, POST, PUT, DELETE), stavový kód (farebne odlíšený: zelená pre 2xx, žltá pre 3xx, červená pre 4xx/5xx), veľkosť odpovede v bajtoch a trvanie v milisekundách. Kliknutím na ktorúkoľvek požiadavku rozbalíte jej detaily: hlavičky požiadavky, hlavičky odpovede, telo požiadavky, náhľad tela odpovede a rozpis časovania.
Zachytávajú sa aj požiadavky odoslané cez Beacon API (bežne používané na analytické signály posielané tesne pred opustením stránky), ktoré je za normálnych okolností ťažké sledovať, keďže sa spúšťajú počas navigácie. Ide o samostatný nástroj oddelený od WebSocket Inšpektora — Network Monitor sa zameriava na HTTP komunikáciu typu požiadavka/odpoveď, zatiaľ čo WebSocket spojenia a ich rámce pokrýva dedikovaný nástroj WebSocket Inšpektor, takže každý panel zostáva prehľadný a čitateľný namiesto miešania dvoch veľmi odlišných typov prevádzky do jedného zahlteného feedu.
Every network request appears in the panel as it happens — page loads, API calls, lazy-loaded resources, and background fetches. The feed updates in real-time with no manual refresh needed.
Click any request to see full details: request URL, method, headers, payload (for POST/PUT), response headers, response body preview (JSON auto-formatted), status code, size, and timing breakdown.
Filter requests by type: XHR/Fetch (API calls), JS (scripts), CSS (stylesheets), IMG (images), Font (web fonts), or All. Isolate API traffic from resource loading to focus on what matters.
Status codes are color-coded for instant recognition: green for 2xx (success), yellow for 3xx (redirects), red for 4xx (client errors) and 5xx (server errors). Failed requests are immediately visible.
Each request shows the response size (in KB) and total duration (in milliseconds). Identify slow API calls, oversized resources, and unnecessary requests that impact page performance.
A summary bar shows total request count and combined size for all captured requests. Filter the summary to see totals per type — how much bandwidth is spent on scripts vs images vs API calls.
Watch XHR/Fetch requests to verify your frontend is calling the correct API endpoints with the right parameters. Click to inspect request payloads and response bodies — catch mismatched data formats instantly.
Red 404 and 500 entries immediately highlight broken resources or failing API calls. See which URLs are failing, when they fail, and what error response the server returns.
Sort by duration to find the slowest requests. Sort by size to find the largest resources. The summary totals show the full bandwidth picture — is the page making too many requests or downloading too much data?
See what network requests the page makes in the background — analytics pings, heartbeat calls, polling requests, lazy-loaded resources. Understand the full network activity beyond what's visible to the user.
Filter requests and check which domains are being contacted. Identify third-party scripts making unexpected network calls — tracking pixels, data collection, or external API calls you didn't know about.
Open the DevSuite Pro floating dock and click the Network Monitor icon. A panel opens and begins capturing network requests immediately.
Use the page normally. Every network request appears in the feed as it's made — API calls, resource loads, and background fetches are all captured.
Click the type filters (XHR, JS, CSS, IMG, Font) to narrow the view. Show only API calls to debug data fetching, or only images to check asset loading.
Click any request row to expand its details: URL, headers, payload, response body, status code, size, and timing.
Red status codes (404, 500) indicate failed requests. Slow durations flag performance bottlenecks. Large sizes suggest resources that need optimization.
