Manhwa Agent Bot
Python · FastAPI · Playwright
Overview
An automated offline-first dashboard that tracks personalized reading lists from Asura Scans. Uses a Playwright-based browser emulation layer to detect new unread chapters and displays them in a Flet desktop widget. An n8n workflow orchestrates 6-hourly scans with Docker containerization, automatically opening new chapters in the browser.

Impact
- 01Architected 3-tier containerized system: Playwright/FastAPI scraper + n8n orchestrator + Flet desktop GUI
- 02Implemented anti-bot bypass with headless Chromium, User-Agent spoofing, and 4-second rate-limit throttling
- 03Designed 12-node n8n automation workflow with dual-trigger (6-hour schedule + on-demand webhook)
- 04Engineered base64 image pipeline to bypass CDN hotlink protection on Cloudflare-protected sources
Features
01
Offline-First Dashboard
Self-hosted with Docker Compose — fully air-gapped operation with no external service dependencies
02
Browser Emulation
Playwright-based headless Chromium scraper with User-Agent spoofing and 4-second rate-limit throttling to avoid detection
03
n8n Automation
12-node n8n workflow with dual-trigger (6-hour cron schedule + on-demand webhook) for tracking reading list updates
04
Flet Desktop Widget
Cross-platform desktop GUI built with Python Flet — real-time reading list updates with one-click chapter launch
05
CDN Bypass Pipeline
Base64-encoded image pipeline to circumvent Cloudflare hotlink protection while maintaining visual previews
06
3-Tier Architecture
Scraper tier (Playwright/FastAPI) → Orchestrator tier (n8n in Docker) → Presentation tier (Flet desktop app)
Architecture
Three-tier containerized architecture: (1) Scraper tier — Playwright headless Chromium controlled via FastAPI REST API scrapes Asura Scans for chapter updates, bypasses Cloudflare with User-Agent rotation and rate-limit throttling. (2) Orchestrator tier — n8n automation platform running in Docker with 12-node workflow triggered every 6 hours or via webhook; compares current chapter list against stored state and triggers notification on new chapters. (3) Presentation tier — Flet desktop app displays reading list with chapter status (read/unread/new) and one-click browser launch.

Manhwa tracker with containerized scraping
Automation-heavy manga/manhwa tracker with containerized scraping and persistent state handling. It tracks all my manhwas and gives me one app with direct links to them across multiple sources. It improved my quality of life.
