Update repository metadata and README to ManagedCode Playwright.Stealth by KSemenenko · Pull Request #2 · managedcode/playwright_stealth

KSemenenko · 2026-02-03T20:03:53Z

Motivation

Remove references to the original AtuboDad/playwright_stealth project and point package and repo metadata to the ManagedCode branded repository.

Description

Updated Directory.Build.props to set RepositoryUrl and PackageProjectUrl to https://github.com/managedcode/Playwright.Stealth and edited README.md to remove the explicit AtuboDad attribution and reflect ManagedCode usage.

Testing

No automated tests were run because this change only updates documentation and package metadata.

+// For whatever weird reason loops don't play nice with Object.defineProperty, here's the next best thing:
+addProxy(WebGLRenderingContext.prototype, 'getParameter')
+addProxy(WebGL2RenderingContext.prototype, 'getParameter')


Guard WebGL2 proxy when WebGL2 is unavailable

This line unconditionally references WebGL2RenderingContext. In browsers or contexts where WebGL2 is disabled or unsupported, that global is undefined and this will throw a ReferenceError during init script evaluation, aborting the rest of the stealth script and potentially surfacing errors in the page. Consider checking typeof WebGL2RenderingContext !== 'undefined' before calling addProxy so the script remains safe on WebGL2‑less environments.

+console.log(opts)


Console.log statement in production code can expose debugging information and potentially reveal the presence of stealth automation. Consider removing this line.

Suggested change

+            }
+            return 'cannot_run'


The function name getDetails is duplicated for both getIsInstalled (line 57) and runningState (line 63). While this doesn't affect functionality due to how they're assigned as object properties, it's confusing and should be corrected to use the appropriate function names for better code clarity and debugging.

+# ManagedCode.Playwright.Stealth (.NET)


The PR description states this change "only updates documentation and package metadata" and mentions removing references to "AtuboDad/playwright_stealth". However, this appears to be a completely new repository with all new files, not just metadata updates. The description should be updated to accurately reflect that this is an initial repository setup for ManagedCode.Playwright.Stealth, not just metadata changes.

+    window.chrome.csi = function () {
+        return {
+            onloadT: csi_timing.domContentLoadedEventEnd,


The variable csi_timing is used but not defined. This should likely be window.performance.timing instead of window.performance.csi_timing. The Navigation Timing API v1 uses window.performance.timing, not window.performance.csi_timing.

+if (!('csi' in window.chrome) && (window.performance || window.performance.timing)) {
+    const {csi_timing} = window.performance
+
+    log.info('loading chrome.csi.js')


The variable log is referenced but never defined, which will cause a runtime error. Either define log or remove this line, or replace it with console.log if logging is intended.

Suggested change

log.info('loading chrome.csi.js')

console.info('loading chrome.csi.js')

+        window.outerHeight = window.innerHeight + windowFrame
+        console.log(`new window outer height ${window.outerHeight}`)


Console.log statements should typically be removed from production code, especially in stealth scripts where the goal is to avoid detection. These logging statements could reveal the presence of stealth automation.

Suggested change

console.log(`current window outer height ${window.outerHeight}`)

window.outerHeight = window.innerHeight + windowFrame

console.log(`new window outer height ${window.outerHeight}`)

window.outerHeight = window.innerHeight + windowFrame

+      try {
+        // Forward the call to the defined proxy handler

This use of variable 'arguments' always evaluates to true.

Suggested change

return handler[trap].apply(this, arguments || [])

return handler[trap].apply(this, arguments)
