FOCUS ON YOUR CODE

From one function to a project you understand.

Tools for reading, exploring and maintaining C/C++ projects.

Unfold call relationships

Explore callers and callees while keeping the current function in place as branches expand.

Learn more

Choose the right parsing approach

From zero-setup lexical indexing to clangd semantics, four modes fit different projects.

Learn more

Index your project. Navigate faster.

Recursively scan C/C++ sources and headers, then find your way with symbols, outlines and function navigation.

Learn more

Workspace status at a glance

See indexing progress, tune CPU usage and inspect logs to understand background work.

YOUR PROJECT. YOUR PARSER.

Four parsing modes. One familiar workflow.

No need to configure everything at once. Start reading, then add richer semantic capabilities as you go.

Recommended

Automatic choice, balancing speed and precision

Keeps a Tag index and any available Compiler service, automatically choosing a parser per file based on compilation-command coverage.

  • Per-file selection
  • Tag without a database
  • Semantics enabled as configured
settings.json
{
  "hornet-cpp.mode": "hybrid"
}

Browse out of the box; semantic features need clangd and a valid compilation database.

FROM FIRST LOOK TO DEEP DIVE

Every expansion keeps you centered.

Keep the current function in place as new branches expand around it. Trace call relationships without the view jumping around.

  • Navigate calls in both directions
  • Hover over edges to trace call direction
  • Double-click nodes to jump to source
