});Works seamlessly with your existing Git workflow
Documentation goes stale the moment you merge. VizRepo keeps diagrams in sync with every scan — no Confluence pages to maintain, no Mermaid files to hand-craft, no README updates to forget.
Stop pinging engineers every time you need to understand “what happens when a user checks out.” Browse the visual flow yourself — in plain English steps, with decision points and error paths clearly labelled.
Stop spending hours reading code to figure out what it does. VizRepo gives you the full picture instantly.
Automatically finds all REST API endpoints across your codebase — GET, POST, PUT, PATCH, DELETE — with full route context.
Each endpoint gets its own interactive flowchart showing decision branches, error paths, and happy paths at a glance.
Trace the full request lifecycle — service calls, DB queries, third-party integrations — rendered as clean sequence diagrams.
Scan specific branches or commit SHAs to diff diagram changes over time and understand how logic evolved.
Live scan progress with automatic polling — watch your diagrams appear as the engine processes your files.
Connect via personal access tokens or OAuth apps. Credentials are encrypted and never stored in plain text.
Paste your repo URL and authenticate with a personal access token or OAuth. Works with GitHub, GitLab, Azure DevOps, Bitbucket, and self-hosted Git servers.
Click scan or set up automatic scanning on push. The engine clones your repo, parses the AST, and extracts all endpoint logic — no config files needed.
Browse every endpoint with its auto-generated flowchart and sequence diagram. Share links with teammates. Keep docs in sync with code, forever.
Join developers who stopped reading thousands of lines of code and started visualizing logic instead.
