WebDriver BiDi for Python — talk to any browser via W3C standard

bidiwave

WebDriver BiDi for Python — talk to any browser via W3C standard.

Features

• W3C WebDriver BiDi — standard, not proprietary CDP
• Cross-browser — Chrome, Firefox, Edge (Safari when BiDi support lands)
• Async-first — native async/await with asyncio
• Event streaming — console logs, navigation, network, contexts in real time
• Input simulation — clicks, keyboard, scroll, drag & drop via input.performActions
• Network interception — block, modify and mock HTTP requests
• Type-safe — Pydantic v2 models, type narrowing with match
• Lightweight — no Selenium, no Playwright required

Install

pip install bidiwave

Quick start

import asyncio
from bidiwave import BiDiClient, StringValue

async def main():
    async with await BiDiClient.connect("ws://localhost:9222/session") as client:
        await client.session.new()

        async with await client.browsing.open("https://example.com") as page:
            # Evaluate JS
            result = await page.evaluate("document.title")
            match result:
                case StringValue(value=title):
                    print(f"Title: {title}")

            # Screenshot
            screenshot = await page.screenshot()
            with open("screenshot.png", "wb") as f:
                f.write(screenshot)

asyncio.run(main())

Console log monitoring

async with await BiDiClient.connect(url) as client:
    async def on_log(entry):
        print(f"[{entry.level}] {entry.text}")

    client.on("log.entryAdded", on_log)
    await client.session.subscribe(["log.entryAdded"])

    async with await client.browsing.open("https://example.com") as page:
        await page.evaluate("console.log('hello!')")
        await asyncio.sleep(2)

Input simulation

async with await BiDiClient.connect(url) as client:
    async with await client.browsing.open("https://example.com") as page:
        ctx = page.context

        # Click at coordinates
        await client.input.click(ctx, x=100, y=200)

        # Type text
        await client.input.type_text(ctx, "Hello, world!")

        # Press Enter
        await client.input.press_key(ctx, "Enter")

        # Scroll down 500px
        await client.input.scroll(ctx, delta_y=500)

        # Drag and drop
        await client.input.drag_and_drop(ctx, 100, 100, 300, 300)

Network interception

async with await BiDiClient.connect(url) as client:
    # Block all requests to ads
    intercept = await client.network.add_intercept(
        phases=["beforeRequestSent"],
        url_patterns=["*ads.example.com*"],
    )

    async with await client.browsing.open("https://example.com") as page:
        await asyncio.sleep(2)

    await client.network.remove_intercept(intercept.intercept_id)
