Breaking News
With $60,000 in funding from Grad Capital, we're accelerating our work to build a new class of developer tools that reduce cognitive load and make complex codebases easier to understand.
Built to Simplify Complex Codebases.
We build tools that solve real developer pain, making large, complex codebases easier to explore, understand, and improve. Every feature is designed to bring clarity, speed, and confidence to the way you read and reason about code.
Call Trace
Visualize every function call and its entire chain of dependencies. Debugging becomes faster, dependency analysis clearer, and modifying complex pipelines feels effortless.
Smart Graph
See your entire codebase organized into semantic layers. Lumyst groups related components and displays them in a clear, hierarchical graph that reflects your system's true structure.
Code Tour
Take a guided walkthrough of your codebase. Watch as Lumyst dynamically builds feature-localized graphs, revealing how modules connect and evolve in real time.
Code-Bound Graphs
Every graph is directly tied to your source code. Click any node to open the exact file beside it, with accurate live context and no hallucinated output.
Built for Developers. By Developers.
We know that for a tool to be truly useful, it has to earn its place in your workflow. That's why we've engineered every part of our system with a developer's core priorities in mind: security, privacy, and zero friction.
Lumyst lives inside VS Code so you never have to switch tabs or open another app. Everything happens right where you write your code.
Your codebase never leaves your machine. All heavy-duty static analysis and graph construction happen 100% locally. Only few code-snippets go to LLMs.
We send only minimal, necessary code snippets to our LLM provider, which operates under a strict zero-data retention policy. Your code is never stored or logged.
Use your own LLM API keys to ensure maximum security and full control over the AI pipeline.
We never store or access your code. Everything stays securely on your device, giving you full privacy and ownership.
Generate analysis once and share it with your team. Others can import it locally without rerunning the full analysis.
