Capabilities

Five browser automation capabilities in one, from simple clicks to complex crawlers.

Capability 1: Web Data Scraping

Scraping Types	Type	Characteristics
Static Pages	HTML direct output	Articles/news/documents
Dynamic Rendered	JS-generated content	SPA apps/infinite scroll
Authenticated	Login-required access	Personal data/backends
Paginated	Multi-page aggregation	Lists/search results
File Downloads	PDF/Excel/images	Reports/attachments/assets

Scraping Pipeline

Target Analysis — URL structure, page type, data location, anti-scrape measures
Strategy Selection — API interception vs DOM parsing vs visual recognition
Selective Extraction — Only fetch needed fields, avoid over-requesting
Data Cleaning — Dedup/format/type conversion
Structured Output — CSV/JSON/Database/direct file write

Anti-Anti-Scrape Strategies

Randomized request intervals (human reading speed simulation)
User-Agent rotation
Cookie/Session persistence
CAPTCHA solving (OCR integration/third-party services)
IP rotation (proxy pool)
Behavior humanization (random scrolls/mouse movement/dwell times)

Capability 2: Web Interaction Automation

Form Filling — Auto-detect field types and fill (text/select/date/file upload)
Click Navigation — Links/buttons/Tabs/menus/dropdowns
Keyboard Operations — Shortcuts/text input/combo keys
Drag & Drop — Sort/slider verification/file drag
Popup Handling — Alert/Confirm/modal/new window
File Operations — Upload/download/save

Capability 3: UI Testing & Regression

Visual Regression — Page screenshots + pixel-level diff comparison
Element Assertions — Element exists/visible/clickable/text content validation
Flow Recording — Record steps into replayable scripts
Multi-Browser Testing — Chrome/Firefox/Safari/Edge compatibility
Responsive Testing — Layout verification at multiple resolutions
Performance Metrics — Load time/FCP/Core Web Vitals

Capability 4: Anti-Detection Strategies

Detection Dimension	Countermeasure
Browser Fingerprint	UA/resolution/timezone/language consistent spoofing
Behavioral	Human-like mouse paths, random pauses, non-linear scrolling
Rate Limiting	Exponential backoff intervals, concurrency control
TLS Fingerprint	Real browsers, not pure HTTP clients
JS Detection	Disable webdriver flag, patch navigator properties
CAPTCHA	Image recognition/third-party solving/human fallback

Capability 5: Multi-Instance Management

Multi-tab Parallelism — Operate multiple pages simultaneously
Multi-Browser Sessions — Isolated context environments
Task Queues — Serial/parallel execution modes
State Persistence — Session save/restore
Resource Monitoring — Memory/CPU/network usage

Workflows

Mode A: Data Collection Task

"Scrape XX data from XX website" → Analyze page → Plan strategy → Scrape → Clean → Deliver

Mode B: Automation Workflow

"Automate XX operation daily" → Record/write script → Schedule execute → Result notification

Mode C: UI Testing

"Check if XX page looks correct at different resolutions" → Multi-res screenshots → Diff comparison → Issue report

Mode D: Anti-Detection Crawling

"XX site has anti-scrape measures, bypass them" → Analyze defenses → Build counter-strategy → Stable collection
