curl-cffi

[Nwokike]

Hello Flet team!

I am building a network search app for Android/iOS using Flet. We rely on packages that use curl-cffi for high-performance async requests and TLS impersonation.

Because curl-cffi includes compiled libcurl CFFI bindings, it currently throws a missing wheel error during flet build apk since there are no pre-compiled Android/iOS wheels available on standard PyPI.

Package Details:

• Name: curl-cffi
• PyPI: https://pypi.org/project/curl-cffi/
• Use Case: High-performance HTTP client with browser TLS fingerprinting and HTTP/2 support.

Could we get curl-cffi added to the mobile forge (pypi.flet.dev) so we can run it natively on Flet mobile?

Thank you!

#6768

I have wheels made in my github repo:

Thanks a lot @Twilight0!

Your wheel builder repository is a lifesaver
I'll use your pre-compiled wheels for our CI mobile builds in the meantime. Upvoted #6768 as well so we can hopefully see it officially on pypi.flet.dev soon!

curl-cffi 0.16.2 is now supported on Android and iOS: https://pypi.flet.dev/curl-cffi

• Example

With this, browser TLS impersonation now works on device — the JA3/JA4 handshake, HTTP/2 settings and header order that go out are a real browser's, not a Python library's.

Note

One thing before you build: you have to narrow your Android ABIs — target_arch = ["arm64-v8a", "x86_64"] under [tool.flet.android]. There is no upstream 32-bit ARM build of curl-impersonate to link against, so flet build apk's default of all three ABIs fails resolving armeabi-v7a.

Give it a try and let us know! 🤟🏿

Okay thanks. Guess I'll sacrifice armeabi-v7a for now
