Vizb, from Goptics, is a command-line utility that converts raw benchmark output into visual reports for developers. It takes textual benchmark results and produces interactive browser-viewable charts that help investigate performance differences. The design emphasizes portability, developer-centric workflows, and visual comparison across runs. Performance engineers and CI-focused developers gain a pipeline-ready way to inspect and communicate benchmark findings quickly.

Vizb parses common benchmark outputs and organizes them for visualization

Input handling is file- and text-oriented: Vizb automatically detects and parses

• CSV files,
• JSON,
• raw CLI benchmark text

Vizb fits into developer pipelines via a CLI-first, pipe-friendly workflow

The tool is designed to be invoked from the shell and can be piped directly from benchmark commands, making it suitable for CI/CD reporting. It generates a single, portable HTML file that opens in a browser without a server or build steps, and it is available on Windows through the Windows Package Manager or as a standalone binary, with macOS and Linux support as well.

Vizb supports multi-dimensional comparison and run merging for side-by-side analysis

For comparative work, Vizb provides multi-dimensional grouping that supports 4D/5D-style exploration and a merging capability to combine multiple benchmark runs into one visualization. These controls let users group by workload, implementation, or test subject and compare execution metrics, memory footprints, and allocation information across environments or timeframes.

The tool assumes developer familiarity and benefits from open-source community backing

Because Vizb is CLI-centric, operators should expect a short learning curve to prepare and pipe benchmark output correctly; casual GUI users may need scripting help. The tool is produced by Goptics as an open-source project and is noted in developer circles and community lists, which helps with example workflows and community-contributed parsing snippets.

A practical, developer-focused reporting tool with a modest learning curve

Vizb is a practical option for developers and performance engineers who prefer CLI workflows and need shareable, offline visual reports integrated into pipelines. Expect some setup time to pipe and format benchmark outputs correctly; teams that document that step as part of CI artifacts gain reproducible visual snapshots for reviews and post-mortems.
