Graph Shortest Path Lab
Build a graph and replay Dijkstra, A*, or Bellman-Ford step by step in your browser.
About this tool
Create a weighted graph and visualize deterministic Dijkstra, A*, and Bellman-Ford shortest-path steps locally. Graph Shortest Path Lab runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- Graph Shortest Path Lab is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
