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)
