Browser-Bookmark Checker

Cross-platform desktop application for merging and deduplicating browser bookmarks with intelligent URL canonicalization and fuzzy title matching.

✨ Features

• Multi-Format Support: Import Netscape HTML and Chrome/Chromium JSON bookmark files
• Intelligent Deduplication: URL canonicalization removes tracking parameters and normalizes URLs
• Fuzzy Matching: Optional fuzzy title matching within same domain using RapidFuzz
• Cross-Platform: Runs on Windows, macOS, and Linux
• Dual Interface: Modern PyQt6 GUI with drag & drop, plus full-featured CLI
• Multi-Language: i18n support for 11 languages
• Privacy-First: Fully offline, no telemetry, no network calls

🚀 Quick Start

# 1) Install
pip install -r requirements.txt

# 2) Run GUI
python -m bookmark_checker

# 3) Or use CLI
python -m bookmark_checker --input bookmarks.html --out merged.html

💿 Installation

See docs/installation.md for platform-specific steps.

Prerequisites: Python 3.11 or higher

# Clone the repository
git clone https://github.com/VoxHash/BrowserBookmarkChecker.git
cd BrowserBookmarkChecker

# Install dependencies
pip install -r requirements.txt

# Optional: Install in development mode
pip install -e ".[dev]"

🛠 Usage

GUI Mode

Launch the graphical interface:

python -m bookmark_checker

Workflow:

1. Click Import Files or drag & drop bookmark files
2. Adjust Similarity slider (0-100, default 85)
3. Click Find & Merge to deduplicate
4. Review results in the table
5. Click Export Merged to save HTML and CSV reports

CLI Mode

python -m bookmark_checker \
    --input file1.html file2.json \
    --out merged_bookmarks.html \
    --similarity 85

Options:

• --input, -i: Input bookmark files (HTML or JSON), multiple files allowed
• --out, -o: Output HTML file path (default: merged_bookmarks.html)
• --similarity, -s: Similarity threshold for fuzzy matching (0-100, default: 85)
• --no-fuzzy: Disable fuzzy title matching

See docs/usage.md and docs/cli.md for detailed documentation.

⚙️ Configuration

Setting	Description	Default
Similarity Threshold	Minimum similarity score (0-100) for fuzzy matching	85
Fuzzy Matching	Enable fuzzy title matching within same domain	Enabled
Export Format	Output format (HTML, CSV)	HTML + CSV

Similarity Threshold Guide:

• 85 (default): Balanced between strict and lenient
• 100: Only exact title matches
• 0-50: Very lenient (may merge unrelated bookmarks)

See docs/configuration.md for full configuration reference.

📚 Examples

• Basic Deduplication — Merge Chrome and Firefox bookmarks
• Programmatic Usage — Use the Python API
• More examples: docs/examples/

🧩 Architecture

Browser-Bookmark Checker follows a modular architecture:

Input Files → Parsers → Normalization → Deduplication → Merge → Exporters → Output Files

Key Components:

• Parsers: Parse Netscape HTML and Chrome JSON formats
• URL Canonicalization: Remove tracking parameters, normalize URLs
• Deduplication: Canonical URL matching + optional fuzzy title matching
• Merging: Select representatives and organize by domain
• Exporters: Generate HTML and CSV outputs

See docs/architecture.md for detailed architecture documentation.

🗺 Roadmap

Planned milestones live in ROADMAP.md. For changes, see CHANGELOG.md.

Upcoming:

• Firefox .jsonlz4 format support
• Safari .plist format support
• Performance optimizations for large datasets
• Enhanced error messages and user experience
