Browser support and system requirements

Supported browsers, devices, and network requirements for using CVViZ smoothly.

Supported browsers

CVViZ targets modern evergreen browsers. The build configuration covers the latest two versions of any browser with more than 1% market share, and explicitly excludes Internet Explorer 10 and older.

This means CVViZ runs reliably on:

  • Google Chrome (recommended — the in-app welcome notice flags Chrome explicitly, and the CVViZ Chrome extension is only available there).
  • Mozilla Firefox
  • Microsoft Edge (Chromium-based)
  • Apple Safari

Internet Explorer is not supported. Older versions of any browser may work but are not officially tested.

Operating systems

CVViZ is a web app and runs anywhere a supported browser runs:

  • Windows
  • macOS
  • Linux
  • ChromeOS

Mobile devices

The app is responsive and works in mobile browsers. Most-used flows — reviewing candidates, submitting interview feedback, replying to messages, checking the dashboard — display well on phones and tablets.

  • iOS — Safari on a recent iOS version.
  • Android — Chrome on a recent Android version.

Network

  • Stable broadband connection (a few Mbps is enough for normal use).
  • Calendar and inbox integrations require connectivity to your email provider's APIs (Google or Microsoft).

Firewall and proxy notes for IT teams

If your network has strict outbound filtering, CVViZ requires HTTPS access to https://app.cvviz.com and its CDN endpoints. If you use Gmail / Outlook integrations, the relevant Google and Microsoft endpoints also need to be reachable from your users' browsers.

Browser settings

  • Cookies — must be enabled for app.cvviz.com.
  • JavaScript — required.
  • Pop-ups — allow pop-ups so OAuth sign-in flows (Google, Microsoft for SSO and email integrations) and external job-board posting flows can open in new windows without being blocked.

Cleaning up if something feels off

If pages load oddly or features look out of date, try in this order:

  1. Hard reload — Ctrl/Cmd + Shift + R.
  2. Clear cookies and cache for app.cvviz.com.
  3. Try in an incognito / private window — rules out extension conflicts.
  4. Disable browser extensions one at a time — ad blockers and script blockers occasionally break OAuth or file uploads.

Why we recommend Chrome specifically

  • The in-app welcome modal explicitly recommends Chrome.
  • The CVViZ Chrome extension (used for sourcing candidates from LinkedIn, GitHub, and other web pages) is only available on Chrome.

Tech stack (FYI)

CVViZ is built on React 18 and Ant Design 5, served via the Umi.js framework. Issues with very old browsers usually trace back to missing modern JS features that the build does not polyfill.
