DeepLens

High-performance "Search Everywhere" for VS Code and Visual Studio 2026

DeepLens provides a powerful, unified search experience across your entire workspace, powered by a high-performance standalone search engine. Quickly find types, symbols, files, and even API endpoints with lightning-fast fuzzy matching and activity-based ranking.

🌟 Key Features

🔍 Search Everywhere

The ultimate navigation tool. Access everything in your workspace from a single dialog. Shift-Shift to open.

• Classes & Types: Find classes, interfaces, and enums instantly.
• Methods & Symbols: Search for functions, methods, and variables.
• Files: Locate any file by name or relative path.
• Text Search: Instant full-text search across your entire codebase with high-performance exclusion rules.
• Commands: Execute VS Code commands directly from the search bar.
• API Endpoints: Specialized search for ASP.NET and web API endpoints.

⌨️ Slash Commands & History

DeepLens features an intuitive command-line style interface within the search bar.

• Filter with ease: Type /t for types, /f for files, or /txt for text search.
• Quick History: DeepLens remembers your recent searches and frequently visited files, making it easy to jump back into context.
• History Management: Easily clear your search history directly from the search interface.

💎 Rider-style CodeVision

DeepLens brings professional IDE features to VS Code with integrated CodeLens counts.

• Reference Counting: See exactly how many times a class, method, or property is used directly above its definition (Shift+F12).
• Implementation Tracking: Quickly see how many classes implement an interface or override a virtual method (Ctrl+F12).
• Quick Navigation: Click the counts to peek or jump to references/implementations.
• Smart Filtering: Configurable to hide counts for simple items to reduce noise.

🌐 Specialized Endpoint Search

DeepLens automatically extracts and indexes API endpoints (like GET /api/users) from your code, allowing you to navigate to the controller or handler responsible for a specific route.

⚡ Smart Matching Engine

• Fuzzy Search: Type partial matches like usebas to find useCallback.
• Ranking: Results are ranked based on match quality, item type, and your personal usage patterns.

🎯 Premium UI/UX

• Integrated Filters: Toggle between search scopes (All, Types, Symbols, Files, Endpoints, Text) with a single click or keyboard shortcut.
• Live Statistics: See real-time counts of files and symbols as they are indexed via the status bar.
• Activity Ranking: DeepLens learns which files you work on most and boosts them in search results.
• File Icons: VS Code–style file icons in search results, matching the Explorer visual style.

🚀 Performance First

• Tree-sitter Powered: Uses native Tree-sitter parsers for C#, TypeScript, JavaScript, Python, Go, Java, and more for near-instant indexing.
• Git Aware: Automatically respects your .gitignore and detects branch switches to keep the index fresh.
• Persistence: Caches indices across sessions for instant startup.
• High Concurrency: Tuned for multi-core systems to index large repositories in seconds.

    "deeplens.enableTextSearch": true,

    // Show reference/implementation counts above definitions (Rider-style)
    "deeplens.codeLens.enabled": true,

    // Show implementation counts above classes, interfaces and methods
    "deeplens.codeLens.showImplementations": true,

    // Minimum number of references to display code lens (0 = show all)
    "deeplens.codeLens.minRefsToShow": 0,

    // Number of files to scan in parallel during text search
    "deeplens.searchConcurrency": 60,
