shardx 0.1.11

Self-contained Rust SDK for the ShardX anti-detect browser — downloads the engine + Widevine + fingerprint library on first use, launches isolated profiles.
Documentation

shardx — Rust SDK

Self-contained Rust SDK for the ShardX anti-detect browser by the ProxyShard team. Same surface as the Python and Node SDKs: on first use it downloads the engine, Widevine CDM, and the bundled fingerprint library from the ProxyShard CDN into a per-user cache dir, then launches isolated profiles with the exact spoofing flags the desktop launcher uses.

Supported hosts: macOS arm64, Windows x64, Linux x64. On macOS/Linux the system unzip is used for extraction (preserves symlinks and exec bits) — install it with brew install unzip / apt install unzip.

Install

Quickstart — launch and drive the browser

session() launches the engine and attaches a chromiumoxide CDP browser in one call (the Rust equivalent of patchright in the Python/Node SDKs). It's behind the default control feature.

use shardx::{ShardX, ShardXOptions, LaunchOptions};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let sdk = ShardX::new(ShardXOptions::default())?;

    // Create a persistent profile from a library template (or None for a
    // random one): enriches a COPY with randomized hw/platform_version and
    // freezes it under a unique id — the fingerprint library is read-only and
    // never launched directly. Do this once per profile.
    let profile = sdk.create_profile(Some("win-rtx4060")).await?;

    // Launch it through a proxy and get a driven browser. randomize: false
    // keeps the frozen fingerprint stable; cookies/cache persist across runs.
    let session = sdk
        .session(
            profile.clone(),
            LaunchOptions {
                proxy: Some("socks5://user:pass@host:1080".into()),
                randomize: false,
                ..Default::default()
            },
        )
        .await?;

    println!(
        "pid={}  quic={}  webrtc={:?}",
        session.engine.pid, session.engine.quic_enabled, session.engine.webrtc_mode,
    );

    // Drive it with chromiumoxide.
    let page = session.new_page("https://example.com").await?;
    println!("title: {:?}", page.get_title().await?);
    // `session.browser` is the full `chromiumoxide::Browser` for anything else.

    session.close().await?; // disconnect + stop the engine
    Ok(())
}

Pass None to create_profile for a random template. To launch your own fingerprint, build a Profile (Profile::from_file(path) or Profile::new(serde_json::json!({ ... }), None)) and hand it to session — launch/session only take a Profile, never a raw library id.

Without a driver (lighter build)

If you don't want the CDP client, disable the feature (shardx = { version = "0.1", default-features = false }) and use launch (no CDP) or launch_cdp (exposes session.cdp_url for your own client):

let profile = sdk.create_profile(None).await?;
let mut engine = sdk.launch_cdp(profile, LaunchOptions::default()).await?;
println!("CDP: {:?}", engine.cdp_url);
engine.stop().await?;

Persistent profiles

list_profiles() / random launches hand back library templates — launch one and it re-reads the same template every time. For a profile you can return to (same fingerprint and cookies/cache) or delete, create a saved profile: it freezes a template (or a random one) with randomized hardware/platform_version under a fresh unique id in its own folder <cache>/profiles/<id>/, exactly like the desktop launcher's "create profile".

use shardx::{ShardX, ShardXOptions, LaunchOptions};

let sdk = ShardX::new(ShardXOptions::default())?;

// Create once (random template, or Some("win-rtx4060")).
let mut profile = sdk.create_profile(None).await?;
println!("{}", profile.id);
println!("{:?}", sdk.list_saved_profiles()?);          // ["<id>", ...]

// Launch it — randomize: false keeps the frozen fingerprint stable; cookies /
// cache persist in the profile's folder across runs.
let session = sdk.session(
    profile.clone(),
    LaunchOptions { randomize: false, ..Default::default() },
).await?;
// ... drive it, then session.close().await?; ...

// Later — even another process — reopen by id: same fingerprint + state.
let profile = sdk.open_profile(&profile.id)?;

// Remove the profile and all its state when you're done.
sdk.delete_profile(&profile.id)?;

Saved profiles never touch the bundled S3 library: templates stay read-only in <cache>/fingerprints/*.json, saved profiles live in <cache>/profiles/<id>/ (holding profile.json + the browser's user-data-dir).

Anti-fingerprint noise

Per-vector noise (canvas / WebGL / audio / DOMRect / sensors / fonts) is off by default. set_noise(...) is declarative — exactly the vectors you list are enabled (with soft defaults), every other one is turned off:

profile.set_noise(&["canvas", "audio", "webgl"]); // only these three on
profile.set_noise(&["canvas"]);                    // audio + webgl now off again
profile.set_noise(&[]);                            // all off
sdk.save_profile(&profile)?;                        // persist the choice

Seeds are derived per-profile at launch — stable across runs, unique per profile — so two profiles with the same vectors enabled still produce different canvas/audio/WebGL fingerprints. Soft defaults: WebGL intensity 0.0005, DOMRect max_offset 1.

Validate a proxy before binding it

let res = sdk.check_proxy("socks5://user:pass@host:1080").await?;
println!(
    "udp={:?}ms  quic={}  webrtc={:?}  exit={} ({})",
    res.udp_ms, res.would_enable_quic, res.would_set_webrtc,
    res.geo.ip, res.geo.country_code,
);

The same SOCKS5 UDP_ASSOCIATE probe the launcher runs decides whether QUIC is enabled and whether WebRTC is forced to tcp_only.

What launch does for you

Before spawning the engine the SDK reproduces the launcher's pre-flight:

  • auto-resolve — fills "auto" timezone / language / geolocation from a live geo lookup through the bound proxy ([resolve_auto_fields]).
  • screen strategy — CapToHost on macOS, UseHost on Win/Linux ([apply_screen_strategy]); override via LaunchOptions::screen_mode.
  • UDP probe — decides QUIC + WebRTC policy from a live relay probe.

Lower-level building blocks

Everything the façade uses is public and reusable:

use shardx::{Runtime, FingerprintLibrary, parse_proxy, probe_udp, geo_check_via,
             randomize_hardware, host_screen_size};

Runtime (download/cache/extract), FingerprintLibrary + Profile, parse_proxy / proxy_to_arg / probe_udp, geo_check_via, randomize_hardware / randomize_platform_version, host_* probes, and the screen / auto_resolve helpers.
