# Browser and device support

> The browsers, operating systems, frameworks and server runtimes Fingerly SDKs support, and how privacy-focused browsers are handled.

Last updated: 2026-09-17

## Browsers

The browser SDK supports every browser that runs ES2020 with `fetch` and `AbortController`.

| Browser | Supported | Tested on |
| --- | --- | --- |
| Chrome and Chromium browsers | Current versions | Chrome 151 |
| Edge | Current versions |  |
| Firefox | Current versions, including strict tracking protection | Firefox 154 |
| Safari on macOS | Current versions | Safari 26.5 |
| Safari on iOS and iPadOS | Current versions | iOS 26 |
| Brave | Current versions | Brave with Shields |
| Tor Browser | Current versions, all security levels | Standard and Safest |

Serve pages over HTTPS. The SDK runs on insecure pages, but several signals are only available in a secure context. `localhost` counts as secure during development.

## Privacy-focused browsers

Browsers that resist fingerprinting are still identified where they allow it, and scored either way. When a browser gives too little to identify anyone, the response has `identifiable: false`, the `fingerprint_suppressed` signal fires, and the request costs less. The SDK never triggers a permission prompt in these browsers either.
