pathfinder

Blazingly fast, lightweight CLI to map & track your codebase.

Examples

Below I ran pathfinder on this codebase with the -R flag to recursively scan all subdirectories. Image was taken at 2025-08-30 3:08 PM EST.

Then I ran the same command, but instead on my installed Go libraries and packages in WSL to benchmark performance. Image was taken at 2025-08-30 3:08 PM EST.

You can see that it found 73,103 files, 18,219 directories, and 44,858,625 total lines.

> time ./bin/pathfinder ../../../go/ -R

# time output (as of 2025-08-30 3:08 PM EST)
./bin/pathfinder -p ../../../go/ -R  5.88s user 8.15s system 281% cpu 4.995 total

This only took 4.995 seconds (on my machine), utilizing 281% of the CPU. This is because pathfinder uses goroutines for concurrent file reading and processing.

I then ran it again on the same directory:

> time ./bin/pathfinder ../../../go/ -R

...

# time output (as of 2025-08-30 3:08 PM EST)
./bin/pathfinder -p ../../../go/ -R  4.69s user 2.97s system 686% cpu 1.117 total

This time it took only 1.117 seconds to run, utilizing 665% of the CPU. The second run is much faster because the OS caches file data in memory, reducing I/O overhead and allowing goroutines to utilize more cores efficiently.
