Palanteer is a visual nanosecond profiler and logger for C++ and Python programs, with a single-header C++ instrumentation library and mostly automatic Python instrumentation. It provides interactive timeline, flame graph, and histogram views, plus Python-scriptable remote commands for deep testing.
Use cases
- profile a C++ application with nanosecond timing
- find memory leaks with a memory profiler
- visualize multithreaded execution on a timeline
- automatically instrument Python functions and allocations
- script remote commands to test a running program
- generate flame graphs from recorded events
- log efficiently with printf-style nanosecond logging
When to choose
- you need low-overhead profiling for C++ or Python
- you want visual timeline and flame graph analysis
- you need combined profiling, logging, and scripted testing in one tool
- you want automatic instrumentation without code changes in Python
When to avoid
- you need a distributed-systems tracer like OpenTelemetry
- you only want a simple sampling profiler with no instrumentation
- you need a license-permissive tool for strict compliance (license is custom)
