Captures real-time execution traces of running code including HTTP calls, SQL queries, exceptions, I/O operations, and data flow, then visualizes this data as sequence diagrams, flame graphs, dependency maps, and trace views. Works by instrumenting code execution within the VS Code environment without requiring code modifications, storing AppMap data snapshots that feed into AI analysis. The extension integrates with the debugger/test runner to passively record application behavior during development and testing sessions.
Unique: Integrates execution tracing directly into VS Code IDE with zero-code instrumentation, capturing application behavior at runtime and converting it into AI-queryable structured data without requiring developers to add logging or modify code. Combines runtime observability with LLM-powered analysis in a single chat interface.
vs alternatives: Differs from traditional debuggers by capturing full execution traces as queryable data structures that feed into AI analysis, and differs from APM tools by operating locally within the IDE rather than requiring external infrastructure.
Provides AI-generated explanations of code behavior by combining static code analysis with captured runtime execution traces. Activated via the `@explain` chat mode, this capability uses the Navie AI assistant (after authentication) to answer questions about what code does, why it behaves a certain way, and what data flows through it. The AI synthesizes information from the current file, project scope, git branch context, and recorded AppMap execution data to generate contextually accurate explanations.
Unique: Combines runtime execution traces with static code analysis to provide explanations grounded in actual application behavior, not just code structure. The `@explain` mode integrates captured AppMap data (HTTP calls, SQL queries, exceptions, data flow) into the LLM context, enabling explanations that answer 'what actually happened' rather than 'what the code says'.
vs alternatives: Provides runtime-informed explanations unlike generic code explanation tools, and integrates directly into the IDE chat interface unlike external documentation tools or standalone debugging platforms.
Identifies security vulnerabilities and issues in code through the `@review` mode and general code analysis, leveraging the LLM's security knowledge combined with codebase context. The AI analyzes code patterns, dependencies, and data flows to detect common vulnerabilities such as injection attacks, insecure authentication, exposed credentials, and unsafe data handling. Results are presented as actionable security findings with context about where issues occur in the codebase.
Unique: Integrates security analysis into the code review workflow using LLM reasoning combined with codebase context, rather than relying solely on pattern matching or static analysis rules. Can incorporate runtime execution traces to detect data flow-based vulnerabilities.
vs alternatives: Provides LLM-powered security analysis integrated into the IDE workflow, unlike external SAST tools or manual security reviews, though less comprehensive than dedicated security scanning platforms.
Identifies performance bottlenecks and optimization opportunities by analyzing recorded execution traces (flame graphs, execution timings) combined with code analysis. The AI examines where code spends the most time, identifies inefficient patterns, and suggests optimizations. This capability is enhanced when AppMap execution traces are available, providing concrete data about actual performance characteristics rather than theoretical analysis.
Unique: Combines execution trace analysis (flame graphs, timings) with LLM reasoning to identify performance bottlenecks and suggest optimizations based on actual application behavior, rather than theoretical analysis. Integrates performance analysis into the IDE chat workflow.
vs alternatives: Provides runtime-informed performance analysis unlike static code analysis tools, and integrates analysis into the IDE workflow unlike external profiling or APM platforms.
Evaluates code maintainability and identifies technical debt through code analysis and review workflows. The AI examines code complexity, duplication, adherence to design patterns, test coverage, and documentation completeness to assess maintainability. Technical debt is identified through patterns like overly complex functions, missing abstractions, inconsistent naming, and insufficient testing. Results are presented with specific recommendations for improvement.
Unique: Provides LLM-powered assessment of code maintainability and technical debt integrated into the IDE workflow, combining static code analysis with AI reasoning about design patterns and best practices. Contextualizes assessment to the specific codebase's patterns and conventions.
vs alternatives: Provides holistic maintainability assessment unlike metrics-only tools, and integrates assessment into the IDE workflow unlike external code quality platforms.
Manages user authentication and workspace context to enable personalized AI assistance. Users can sign in via email, GitHub, or GitLab credentials to unlock the Navie AI assistant and access personalized features. The extension maintains workspace context including the current file, project scope, git branch information, and recorded AppMap traces. Authentication state and workspace context are used to customize AI responses and enable features like branch-aware code review.
Unique: Integrates authentication and workspace context management directly into the VS Code extension, enabling personalized AI assistance without requiring external account management. Supports multiple authentication methods (email, GitHub, GitLab) and maintains workspace context across chat sessions.
vs alternatives: Provides IDE-integrated authentication unlike external authentication services, and maintains workspace context automatically unlike tools requiring manual context specification.
Performs AI-driven code reviews by analyzing differences between the current branch and base branch, using the `@review` chat mode to identify security issues, maintainability concerns, logic errors, and performance problems. The extension accesses git context to compare code changes and applies the selected LLM to generate review feedback. Reviews can be enhanced with runtime execution traces if AppMap data has been recorded for the changed code.
Unique: Integrates git branch awareness directly into the chat interface, allowing reviews to be scoped to specific changes rather than entire files. Can optionally incorporate runtime execution traces to identify logic errors and performance issues that static analysis alone would miss.
vs alternatives: Provides local, IDE-integrated code review without requiring external CI/CD systems or PR platform integrations, and can enhance reviews with runtime data unlike traditional static analysis tools.
Generates detailed implementation plans for coding tasks using the `@plan` chat mode, which breaks down requirements into actionable steps. The AI analyzes the current codebase context, project structure, and existing patterns to create plans that align with the application's architecture. Plans are generated as structured text that developers can follow sequentially to implement features or refactor code.
Unique: Generates implementation plans that are contextualized to the specific codebase by analyzing project structure, existing code patterns, and architecture, rather than providing generic implementation advice. Integrates planning directly into the IDE chat workflow.
vs alternatives: Provides codebase-aware planning unlike generic project management tools, and integrates planning into the development workflow unlike external documentation or specification tools.
