Most A/B tools need traffic, a growth team, and weeks of setup. Mutatr just needs a sentence. Tell it what to optimize and it autonomously suggests tests, implements variants in your actual codebase, and scores them against synthetic customer personas — complete with attention heatmaps, per-metric scorecards, and ship-or-iterate recommendations. When a variant wins, push it as a PR directly to your repo in one click. Zero traffic required. Results in minutes. All from your desktop.
