What is AppMap?
AppMap instruments your application to capture real-time snapshots of code execution, data flow, and behavior — every time your app runs, with zero effort and no code changes.
This gives AI tools like Navie, Copilot, and Cursor the runtime context they've been missing. Not just what your code is, but what it just did.
With this live understanding of your app's behavior, you get smarter suggestions, faster debugging, and fewer code defects, right in your code editor and CI.

"Probably one of the most powerful tools I have seen running in Visual studio code. their latest version includes a AI assistant that can feed from the appmaps + language models to build documentation, explanations, etc. in seconds."

Review code 125x faster, with 3x more review criteria.
Let AppMap perform a full-spectrum, runtime-aware review of your branch. Customize your review criteria or have AppMap compare your work to a technical specification. Then let it deliver clear, actionable feedback on exactly what was analyzed. No black boxes, just runtime-grounded insights.
Code Quality
Ensures your changes follow best practices and are easy to read and maintain.
Documentation
Verifies that public-facing code is well-documented and understandable.
Security
Surface vulnerabilities and unsafe behaviors before they reach production.
Runtime Flaws
Detect errors and unexpected behaviors that only manifest during execution.
Testing & Coverage
Analyze test depth, edge cases, and highlight where coverage should be expanded.
Compatibility
Verifies your change won't break downstream consumers or integrations.
Performance
Identify hotspots, resource use, and bottlenecks.
Design & Architecture
Confirms your implementation follows established patterns and fits the system's structure.

| Capability | AppMap Review | Static Code Review |
|---|---|---|
| Runtime-aware analysis | Records real execution data (code + DB + I/O) | Static diff only |
| Review domains (single pass) | Comprehensive coverage spanning critical domains and runtime data sources | General quality hints; no runtime checks |
| Missing-test detection | Detailed detection by dynamic analysis | Detection by LLM |
| Performance hotspots | Observes slow queries, function calls, and hotspots | Not included |
| Security insights | Detects auth gaps, insecure tokens, leaked secrets, and other runtime issues | Not included |
| Transparency | Shows exactly what was recorded & scanned | LLM output, often without context |
Your application runs. AppMap watches.
Whether you're onboarding, debugging, or modernizing code, AppMap shows how everything fits, without any guesswork.
AppMap watches your application in action, recording how APIs, functions, and services actually behave. AppMap depicts this information as interactive diagrams that you can search and navigate.
You can see how functions, web APIs, databases, security, I/O, and other services all work together when your application runs. AppMap is an extension to your code editor, so its information is always available when and where you code. Whether you are documenting your internal APIs or reverse engineering an old application, AppMap has the information you need to keep moving forward.
Missing context? Your copilot thinks so.
AppMap captures what static code can't: the real behavior of your application at runtime. This rich data gives AI tools (and humans) the insight they need to answer deeper questions and make smarter suggestions.
Now your LLM-backed tools can answer questions like "What just happened?" with real runtime context.
What AppMap records:
- Function calls, return values, exceptions
- HTTP requests and responses (status codes, headers, parameters)
- SQL queries and database behavior
- Security and auth events
- Background jobs and message handling
- Logging, serialization, and more
Runtime context In. Intelligence out.
AppMap powers Navie, your AI assistant designed specifically to understand and improve code based on how it actually behaves.
Navie uses static and runtime insights to help you:
- Debug complex issues
- Ask deep, contextual questions about unfamiliar code
- Make safer, more informed code changes
- Get precise answers grounded in real application behavior
- Perform runtime-aware code reviews
With flexible backend options (GitHub Copilot, OpenAI, Anthropic, Google or self-hosted), Navie supports secure, enterprise-ready AI development — with zero fine-tuning required.
