Automate with Playwright

5.0.0

Added

  • Engine: accountless mode is now supported, so profile launch is available without creating an account
  • GUI: OIDC-based login and registration flow
  • SDK: we now bundle the pw-bridge executable with the SDK. Use the new JunglefoxHelper static helper class when using the Junglefox kernel (for Firefox profiles) with Playwright. See Playwright integration (Junglefox)
  • Engine: fails to start with a fatal error if legacy Email/Password authentication parameters are set; use PAT (Personal Access Token) authentication instead. See Getting started
  • Engine: a default Chroma profile is created after the first app login
  • GUI: web/Docker mode — Kameleo Desktop app-only features (export, import, log folders) are hidden or disabled when running in a browser
  • SDK: new method to verify that the Kameleo Engine is running before any other interactions: KameleoLocalApiClient.verifyEngineReady() (JS) / VerifyEngineReadyAsync() (C#) / verify_engine_ready (Python)
  • API: user-info endpoint includes the app version in the response
  • GUI: global HTTP error interceptor with per-request suppression support
  • GUI: added Huawei vendor and renderers to WebGL list

Changed

  • SDK: user-info endpoint now returns running profile counts in a clearer structure: remove redundant runningTeamProfiles, and expose runningProfiles.user and runningProfiles.tenant instead. See Concurrent browsers
  • API: replace email/password with PAT (Personal Access Token) authentication, so API token-based auth is used instead of username/password
  • Kameleo.CLI is being renamed to Kameleo.Engine
    • Kameleo.CLI executable -> Kameleo.Engine
    • macOS Kameleo.app/Contents/Resources/CLI directory -> Kameleo.app/Contents/Resources/Engine
  • fingerprint search has smarter defaults for the best masking results: it prefers fingerprints for the host OS (Windows/macOS/Linux), desktop over mobile, and Chrome over other browsers. See Filter browser fingerprints
  • GUI: profile creation now uses the engine's host OS as default instead of the GUI app's OS
  • Integrate VNC viewer into Kameleo web GUI
