0x is a single-command Node.js profiling tool that generates interactive flamegraphs from stack traces. It wraps any Node process, captures CPU stacks, and produces a self-contained flamegraph.html visualization.

Use cases

• profile a node.js app and generate a flamegraph
• find cpu bottlenecks and hot paths in my code
• load test a server and profile it in one command
• visualize stack traces of a node process
• profile a production node server
• generate flamegraphs on any platform node runs on

When to choose

• you need quick, zero-config CPU profiling of Node.js v20+ processes
• you want interactive flamegraphs viewable in Chrome with a single command
• you need to profile under load using tools like autocannon via the --on-port flag

When to avoid

• you need heap/memory profiling rather than CPU stack sampling
• you are profiling non-Node.js runtimes or languages
• you require continuous production A-style profiling rather than on-demand capture
