Qatorika — Browser QA Toolkit

A local-first browser testing toolkit for QA engineers.

Qatorika brings practical manual and exploratory testing tools into one local-first browser workspace. Open tools from the extension or from a nested right-click menu on the page, selected text, link, image, or editable field. Inspect the selected element, test temporary CSS changes, copy stable selectors, review forms, generate test data, compare JSON, decode JWTs, and prepare reproducible bug reports. For deeper diagnostics, Qatorika can capture network requests and console errors, replay authorized requests, manage cookies and web storage, configure environments, mock responses, test viewports, annotate screenshots, and record structured test sessions. Highlights: - CSS inspector with hover highlighting, click-to-select, font, color, size, spacing and selector details - Network Inspector and Error Hunter with clear failure highlighting - API client, request replay and response mocking - Form Inspector and Form Fuzzer - JSON formatter/diff, URL tools, JWT decoder and data generators - State Manager for cookies, localStorage and sessionStorage - Bug Report Builder, screenshot annotation and test-session export - Russian and English interface Privacy by design: working data is processed locally in the browser. Qatorika has no analytics, ads, accounts or remote backend. Page access and recording begin only after an explicit user action.
