Why webQsee

DevTools shows what's happening. webQsee gives you a copy.

Chrome DevTools is great for live inspection, but the moment you reload the tab or close the panel, the evidence is gone. webQsee turns ephemeral browser activity into permanent, shareable artefacts, searchable, filterable, exportable, replayable.

  • Selective export. Pick exactly the requests, console messages or WebSocket frames you want to share, DevTools forces you to export everything.
  • Session replay. Re-watch the visual flow alongside the underlying traffic. Skip the "can you reproduce?" loop.
  • Rule-based error detection. Codify what a 5xx with this stack trace means once, surface it for everyone forever.
  • Two cloud modes. Start free on webQsee-provided S3 (7-day trial); upgrade to bring your own bucket on Amazon S3 or min.io with full data residency control.
  • Imports too, not just exports. Drop in a .har from DevTools, Charles or Postman, or a colleague's webQsee capture, and analyze it as if you had recorded it.

What you can do with webQsee

Capture every signal a tab gives off, without leaving it.

Network, console, WebSocket, Server-Sent-Events, video, screenshots, cookies, environmental data, all in one panel, all selectable, all exportable to HAR, Excel or webQsee's own session-replay format.

Network & Console Analyzer

HTTP, WebSocket, Server-Sent-Events and console output, grouped by domain, type and status, with multi-column sorting and per-row filters.

Inside the Analyzer

Behavior Reports / Session Replay

A replayable video of a tab plus all the traffic and console output that happened on it, like a flight recorder for your web app.

Event Snapshots

Our richer alternative to HAR: network + console + screenshot + cookies + environment, in a single shareable .esa file.

HAR vs Event Snapshot

Screenshots, Screencasts & Videos

Full-page screenshots that beat sticky headers, plus tab/window/display screencasts with audio, microphone and Dashcam-Mode (keeps the last 30-60s).

Capture options

Screenshot Editor

Crop, annotate, blur and highlight directly in the extension, no detour through external image apps.

Editor tools

Customizable Error Detection

Write reusable rules that flag known issues (stack traces, status codes, log patterns) so junior engineers spot what seniors already know.

Rule engine

Cloud Gallery, two modes

Free 7-day trial on webQsee-provided S3 (you pick the AWS region), or bring your own Amazon S3 / min.io for full data residency control. Captures go directly to S3, metadata only on our servers.

How storage works

Cloud Sharing

Temporary links that need no account on either end, or permanent public and team-private links. Recipients view in-browser at view.webqsee.com, no install required.

Sharing channels

Export & Import Anywhere

HAR (all / selected / filtered), Excel, MHTML, cookies, plus our own Behavior Archive (BAR) and Event Snapshot (ESA) formats.

Cloud Gallery

Your captures. Your storage. Your team's URL.

webQsee's Cloud Gallery is "bring your own storage" by design. Connect an Amazon S3 bucket (or any S3-compatible target like self-hosted min.io) and the browser extension talks to it directly. We never see the payload, only the metadata required to render a gallery.

Share a capture and your teammates open it at view.webqsee.com, the web mode of webQsee. They get the full analyzer experience without installing anything.

In four steps

From "this is broken" to "here's the recording".

1 · Install

Add webQsee to Chrome or Edge in one click. No account required for capture.

2 · Click record

Pick Behavior Report, Event Snapshot, Screenshot or Screencast. webQsee handles the rest.

3 · Analyze

Group, sort and filter every event by domain, type and status. Apply your team's error-detection rules.

4 · Share

Copy a link or export to HAR / Excel / ESA / BAR. Recipients open it at view.webqsee.com, no install, no account.

Privacy by design

Local-first. EU backend. You pick where captures live.

  • Captures live in your browser's IndexedDB until you choose to upload them.
  • Cloud Gallery is either webQsee-provided (you pick the AWS region) or your S3 bucket. webQsee's backend only ever stores titles, descriptions and status.
  • webQsee's account and metadata backend runs in the European Union (Frankfurt).
  • Manifest V3 from day one, works with Chrome's modern extension model.
