PromQL Formatter

Prettify PromQL queries locally in your browser — VictoriaMetrics & Prometheus backends, no data leaves your machine.

PromQL Formatter prettifies dense, hard-to-read PromQL queries into a clean, multi-line form — right from your browser toolbar. No servers, no sign-in, and nothing ever leaves your machine. Features • One-click formatting from the toolbar popup — paste, click Format, copy. • Two formatting backends: – VictoriaMetrics (metricsql) — the default, MetricsQL-aware prettifier. – Prometheus — a parser-based formatter with Grafana $variable support. • 100% local: all processing runs in your browser via WebAssembly. • No data collection, no telemetry, no accounts. • Free and open source (Apache-2.0). How it works The formatting engine is compiled from Go to WebAssembly and runs entirely inside the extension. The same engine is available as a standalone CLI and Go library: https://github.com/xhinliang/promql-formatter-cli Source code: https://github.com/XhinLiang/promql-formatter
