Rooted in Your Code. Designed for Your Reality

OpenAPI Explorer takes your OpenAPI spec and brings it to life. It doesn’t just render your API; it understands your codebase. By leveraging advanced LLMs layered on top of MCP and LSP protocols, OpenAPI Explorer dives deep into your local repository. It reads, interprets, and thinks in the structure of your actual code, providing insights that generic tools can only dream of.

Core Features: Unlock Unprecedented Clarity & Efficiency

Go beyond surface-level analysis. OpenAPI Explorer gives you the power to truly understand and master your backend.

Visual map of endpoints and service interactions
See your entire backend at a glance. Instantly understand relationships, dependencies, and data flow between services and endpoints, transforming abstract code into a clear, interactive diagram.
Inline code explanations and function summarization
Demystify complex logic. Get plain English explanations of functions, trace logic flow step-by-step, and understand intricate code segments without hours of manual deciphering.
Complexity scoring
(space/time)
Write more efficient code, proactively. OpenAPI Explorer analyzes your code and provides scores for complexity and readability, helping you identify potential bottlenecks and areas for optimization.
Regression comparison between versions
Catch bugs before they hit production. Intelligently compare changes between commits or versions to detect regressions and understand the impact of new code with unparalleled precision.
Documentation
auto-generation
Keep your documentation effortlessly up-to-date. Generate comprehensive, accurate, and context-aware documentation directly from your codebase, saving valuable developer time.
Custom LLMs trained for your backend code
Get hyper-relevant insights, not generic advice. Our LLMs are trained and fine-tuned on your specific codebase, understanding its unique patterns, Naming conventions, and architectural nuances.

More Than Just Another AI Tool.
