Network+

About

Network+ is a custom DevTools Network panel for developers who feel the built-in one is cramped. It runs alongside the standard panel — you switch to "Network+" inside DevTools and get:

  — CLEAN URL COLUMN
    Strip the page origin and your own per-type prefixes (separated by spaces) so the URL column shows only the part you care about.

  — SMART FILTERS
    Filter by type, by HTTP method (click the letter in the row), by URL substring. Alt+click to exclude. Group identical requests with a "×N" badge and group-hover.

  — JSON-AWARE EVERYTHING
    Response, Payload and WebSocket frames are rendered as a real collapsible JSON tree with full-text search (▲/▼ navigation, hide-non-matches mode, ← to refocus the search input).

  — SIDE-BY-SIDE DIFF
    Ctrl/Cmd+click any row to compare it with the previously selected one. Two diff modes: line diff and semantic JSON diff. Swap sides with one click.

  — ON-PAGE OVERLAY
    Request details render as a draggable, resizable overlay on the inspected page itself — your request list stays at full width. Sections (Headers / Payload / Response / Timing / WS frames) can be reordered by drag.

  — WEBSOCKETS DONE RIGHT
    Each frame on its own line with auto-detect of JSON payload, the same JSON tree + search inside. Heartbeats hidden by one toggle. Send arbitrary WS frames into a live connection from the panel, save reusable templates that
  survive DevTools restarts.

  — MOCKS WITH ERROR SUPPORT
    Intercept fetch / XHR with synthetic responses, including 4xx/5xx with custom body and headers. "Mock from response" creates a rule in one click from any captured response. Editor with Beautify / Compact for JSON bodies.

  — RESPONSE DELAY
    Delay future requests for selected URLs by N ms; clock badge in the row + accurate time accounting.

  — PERSISTS BETWEEN SESSIONS
    Filters, prefixes, mocks, delays, WS templates and UI preferences are saved per-profile and survive DevTools restart.

  — UI YOU CAN TUNE
    Alt+= / Alt+− / Alt+0 to scale the font; Alt+H opens a bilingual (English / Russian) help overlay listing every shortcut.

  NO BACKEND. NO BUILD STEP. NO TRACKING.
  All logic runs in your browser. The extension does not transmit any captured data anywhere.
