Git inside your repo.
Paste a GitHub repo and get an interactive system design diagram, built by parsing the code. Break it down from services to functions, and trace a request from page to database.
Parsed, never guessed
Every box and arrow comes from the code and links to its source line. The same commit always gives the same diagram.
Services down to functions
Break any service down in place: modules, files, then the functions inside.
Follow a request
Trace a request from the page that sends it to the route, the database, and the APIs it calls.
Gaps stay visible
A call the analyzer can't pin down is drawn as unresolved, with the reason, instead of a guessed line.
