Playfast - Lightning-Fast Google Play Store Scraper

Playfast ⚡

Lightning-Fast Google Play Store Scraper

Playfast is a high-performance Google Play Store scraper built with Rust + PyO3, delivering 5-10x faster performance with true parallel batch processing.

✨ Features

• 🚀 Blazingly Fast: Batch API is 5-10x faster than sequential
• ⚡ True Parallel: Rust core completely releases GIL
• 🦀 Pure Rust: HTTP + parsing all in Rust for maximum performance
• 🔒 Type Safe: Full Pydantic validation and type hints
• 💾 Memory Efficient: Only 1.5 KB per app, linear scaling
• 🌍 Multi-Country: 247 countries, 93 unique Play Stores
• 📦 Batch API: High-level functions for easy parallel processing

📊 Performance

Batch Processing makes bulk operations 5-10x faster through true Rust parallelism!

Method	Time	Speedup
Batch API	~3s	6-8x 🚀
RustClient + ThreadPool	~3-4s	6-7x
AsyncClient (concurrent)	~3-5s	5-7x
Sequential	~20-30s	1x

Benchmark: Fetching 3 apps across 3 countries (9 requests total)

🚀 Quick Start

Installation

Using pip (traditional):

pip install playfast

Using uv (recommended - faster):

uv add playfast

Using poetry:

poetry add playfast

Option 1: Batch API (Recommended - Easiest & Fastest)

from playfast import fetch_apps

# Fetch multiple apps across countries (parallel!)
apps = fetch_apps(
    app_ids=["com.spotify.music", "com.netflix.mediaclient"],
    countries=["us", "kr", "jp"],
)
print(f"Fetched {len(apps)} apps in ~3 seconds!")

Option 2: RustClient (Maximum Performance)

from playfast import RustClient

client = RustClient()

# Get app information (GIL-free!)
app = client.get_app("com.spotify.music")
print(f"{app.title}: {app.score}⭐ ({app.ratings:,} ratings)")

# Get reviews
reviews, next_token = client.get_reviews("com.spotify.music")
for review in reviews[:5]:
    print(f"{review.user_name}: {review.score}⭐")

Option 3: AsyncClient (Easy Async)

import asyncio
from playfast import AsyncClient


async def main():
    async with AsyncClient() as client:
        app = await client.get_app("com.spotify.music")
        print(f"{app.title}: {app.score}⭐")


asyncio.run(main())

🏗️ Architecture

Playfast uses pure Rust for both HTTP and parsing:

┌─────────────────────────────────────┐

Three Client Options

Method	Speed	Ease	Best For
Batch API	⚡⚡⚡	⭐⭐⭐	Multiple items
RustClient	⚡⚡⚡	⭐⭐	Single items
AsyncClient	⚡⚡	⭐⭐	Async code

🌍 Multi-Country Optimization

Playfast optimizes global data collection:

from playfast import get_unique_countries, get_representative_country

# Instead of 247 countries, use 93 unique stores (2.7x faster!)
unique = get_unique_countries()  # 93 unique Play Stores

# Get representative for any country
rep = get_representative_country(
    "fi"
)  # Finland → Vanuatu store (shared by 138 countries)
