## プロジェクトの歴史と使われ方

flamebearer is a JavaScript CPU trace analysis CLI for Chrome DevTools performance recordings and Node `.cpuprofile` files. The current README positions it as a compact text-summary tool rather than an HTML flame-graph renderer.

### プロジェクトの歴史

The official GitHub repository was created in 2018 and was formerly available under Mapbox; GitHub now redirects the Mapbox URL to mourner/flamebearer. The README says version 1 generated an HTML flamegraph for Node traces, then the project lay dormant after 2018.

In 2026 the project was revived with a new purpose: a CLI-oriented analyzer for performance optimization loops, especially useful for agents and humans reading CPU traces without opening a GUI.

### 採用の歴史

The package's adoption niche is Node and browser performance work. It can be installed globally with npm, used through `flamebearer-node` to profile a script, or pointed at Chrome trace and Node CPU profile files.

Its README explicitly leaves GUI flamegraph browsing to Speedscope and instead optimizes for one-page terminal summaries, drill-down flags, source-map support, hot source lines, and long-task visibility.

### 使われ方

Typical commands include `flamebearer-node bench.js`, `flamebearer profile.json.gz`, and `flamebearer CPU.*.cpuprofile`. Drill-down flags restrict stacks, threads, row counts, and time ranges.

The tool does not document a persistent config file or credentials file; usage is command-line and profile-file driven.

### パッケージ好きにとっての重要性

flamebearer is interesting because it changed identity without abandoning the package: from a Node HTML flamegraph generator inspired by earlier profiling tools into a fast textual trace summarizer aimed at modern command-line workflows.

It sits in the flamegraph family tree but intentionally chooses a terminal-first UX, which makes it attractive for CI logs, scripted profiling runs, and automated performance investigations.

### タイムライン

- 2018: Official repository created.
- 2018: Version 1 era generated HTML flamegraphs for Node traces, according to the README.
- 2026: Project revived as a CLI CPU trace analysis tool for agents and humans.

### Related projects

- Brendan Gregg's FlameGraph is credited for the flamegraph concept.
- 0x is credited as the original inspiration for the project.
- Speedscope is named as the GUI flamegraph viewer that flamebearer does not try to replace.
