grindr.rs

Unofficial async Rust client for the Grindr API, powering Open Grind client.

[!Important] This is an unofficial library, not affiliated with or endorsed by Grindr. It is provided for research and interoperability. Automating access may violate Grindr's Terms of Service. You are responsible for how you use it.

Features

• Async, clonable client built on tokio and wreq
• Fingerprint matching Grindr's official Android APK's network lib: TLS (JA3/JA4), HTTP/2 (frames, pseudoheaders), required headers
• Session handling — tokens are refreshed automatically
• Background WebSocket with automatic reconnect and states callback
• Device identities spoofing — store DeviceInfo along session token to decrease the chance of triggering Cloudflare block pages

This crate is a transport: it handles authentication, fingerprinting, connection, but does not ship typed models for every endpoint. You choose the path and deserialize the body yourself.

Installation

[dependencies]
grindr = "0.1"
tokio = { version = "1", features = ["macros", "rt-multi-thread", "sync"] }
serde_json = "1"

Versioning

This crate's version is <lib version>+<Grindr APK version>. For example, 0.1.0+26.9.1.163471 is library 0.1.0 targeting APK 26.9.1.163471. The +<apk> suffix is SemVer build metadata: informational only, and ignored by Cargo when resolving versions. Retargeting the APK is treated as a breaking change, so it bumps the minor, requiring manual upgrade. The targeted version is also exposed as grindr::APP_VERSION.

Quick start

use grindr::{DeviceInfo, GrindrClient, Method};

#[tokio::main]
async fn main() -> Result<(), grindr::GrindrError> {
    let device = DeviceInfo::generate();
    let client = GrindrClient::new(device, None)?;

    let me = client.login("m@example.com", "yourpassword").await?;
    println!("logged in as profile {}", me.profile_id);

    // URL must start with `/`
    // Session token is added automatically
    // API reference: <https://opengrind.org/grindr-api/>
    // Dev tool: <https://git.opengrind.org/open-grind/grindr-api-dev-tool>
    let resp = client
        .request_authenticated_raw(Method::GET, "/v3/me/profile", None)
        .await?;
    println!("status {}", resp.status);
    let profile: serde_json::Value = serde_json::from_slice(&resp.body).unwrap();
    println!("{profile:#?}");

    Ok(())
}

Sessions & device identity

// Load `device` and `saved` from disk
let client = GrindrClient::new(device, saved)?;

// Persist session whenever it changes
let mut sessions = client.session_receiver();
tokio::spawn(async move {
    while sessions.changed().await.is_ok() {
        // Option<Session>
        let current = sessions.borrow().clone();
        // Serialize to disk and store securely
        save_session(&current);
    }
});

WebSocket

The realtime WebSocket is opt-in, REST works without it. Call client.connect().await once to start the shared background socket, which then connects as soon as a session exists. Subscribe to events and send commands:

use grindr::WsCommand;

// Subscribe to events
let mut events = client.ws_receiver();
tokio::spawn(async move {
    while let Ok(event) = events.recv().await {
        println!("event {}: {}", event.event_type, event.payload);
    }
});

// Send a command
client
    .ws_sender()
    .send(WsCommand {
        r#type: "chat.v1.typing".to_owned(),
        ref_id: "1".to_owned(),
        payload: serde_json::json!({ "conversationId": "abc" }),
    })
    .await
    .ok();

The background task is never started for you. client.connect().await is the only thing that starts it, and it's idempotent and shared across clones. Until you call it, no socket is opened and ws_receiver() produces nothing. Watch the connection with GrindrClient::connection_state, and observe failed background token refreshes via GrindrClient::auth_event_receiver.

GrindrClient

Types

• DeviceInfo — device identity, build with DeviceInfo::generate() or DeviceInfo::default()
• Session — session token and other secrets
• SessionKind — Email or Google
• LoginResult — { profile_id }, returned by the auth methods
• RawResponse — { status: u16, body: Vec<u8> }
• WsCommand — websocket command { type, ref_id, payload }
• WsEvent — websocket event { event_type, payload }
• WsConnectionState — Connected / Disconnected
• AuthEvent — { message, unauthorized } from background refreshes
• GrindrError — the crate error type (Http, Auth, Api, Unauthorized, InvalidRequest); GrindrError::from_response(status, body) maps a non-success RawResponse the same way the typed methods do
• Method — re-exported wreq::Method for request_authenticated_raw
• Bytes — re-exported bytes::Bytes for request_authenticated_bytes

Low-level helpers

For building your own wreq::Client with an identical fingerprint:

• probe_emulation() -> wreq::EmulationProvider — tls/http2 emulation profile
• build_user_agent(device, tier) -> String — User-Agent value
• build_device_info_header(device) -> String — L-Device-Info value
• GrindrHeaders::build(device, ua, authorization, roles) — full and correctly ordered headers list

Examples

Observe TLS session resumption:

cargo run --example warm_probe

Assert the emulated fingerprint:

cargo run --example fingerprint_check

The fingerprint_check example verifies JA3/JA4, the Akamai http/2 fingerprint and header ordering against tls.peet.ws. Pass --all flag to check both http/2 and http/1.1 (websocket) clients.

Minimum supported Rust version

Rust 1.80.
