The current README positions it as a compact text-summary tool rather than an HTML flame-graph renderer. ### Project history 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. ### Adoption history 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. ### How it is used 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. ### Why package nerds care 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. ### Timeline - 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. ### Sources - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** flamebearer - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [node](https://www.automicvault.com/pkg/brew/node/) - Runtime dependency declared by Homebrew. - [flamegraph](https://www.automicvault.com/pkg/brew/flamegraph/) - Shares av.db curated category or tags: cli, developer-tools, flamegraph, performance, profiling. - [gprof2dot](https://www.automicvault.com/pkg/brew/gprof2dot/) - Shares av.db curated category or tags: cli, developer-tools, performance, profiling, visualization. - [cargo-flamegraph](https://www.automicvault.com/pkg/brew/cargo-flamegraph/) - Shares av.db curated category or tags: cli, developer-tools, flamegraph, performance, profiling. - [qcachegrind](https://www.automicvault.com/pkg/brew/qcachegrind/) - Shares av.db curated category or tags: cli, developer-tools, profiling, visualization. - [snakeviz](https://www.automicvault.com/pkg/brew/snakeviz/) - Shares av.db curated category or tags: cli, developer-tools, profiling, visualization. - [counts](https://www.automicvault.com/pkg/brew/counts/) - Shares av.db curated category or tags: cli, developer-tools, performance, profiling. - [memray](https://www.automicvault.com/pkg/brew/memray/) - Shares av.db curated category or tags: cli, developer-tools, performance, profiling. - [py-spy](https://www.automicvault.com/pkg/brew/py-spy/) - Shares av.db curated category or tags: cli, developer-tools, performance, profiling. ## Combined YAML source View the package source record on GitHub.
