Visual themes, Live/Dev safety indicators, per-node coloring, and canvas customization for n8n. Your n8n, your canvas. 🎉 UPDATE v2.22.0 - The Compatibility & Security Update Full n8n v2.22.0 Support: Completely patched all visual regressions and layout breaks caused by n8n's newest native update. Brand New Name: We are officially now n8n Prime Playground! Security First: We completely removed the tabs permission. n8n Prime Playground is the only Chrome extension that adds visual themes, UI customization, and a production safety system to n8n — the open-source workflow automation platform. Transform your n8n interface from a flat grey editor into a fully customized visual environment. Change themes, fonts, colors, node styles, canvas wallpapers, and execution state indicators — all from a single extension popup. ────────────────────────────────────── 🚨 n8n PRODUCTION SAFETY INDICATOR ────────────────────────────────────── The most important feature in n8n Playground isn't visual — it's protective. When you open an n8n workflow that is Published and Active, the extension immediately fires a hard red border across the entire n8n interface with a "🔥 LIVE MODE 🔥" banner. You will never accidentally edit a live, running n8n workflow without knowing it. Draft and unpublished n8n workflows display a calm blue DEVELOPER indicator. Switch between environments instantly and always know exactly what state your workflow is in. After every n8n workflow execution, connector lines turn green for successful paths and red for errors — visual debugging directly on the n8n canvas, no logs required. ────────────────────────────────────── 🎨 n8n THEMES — NINE VISUAL ENVIRONMENTS ────────────────────────────────────── Nine hand-crafted n8n themes that simultaneously restyle every surface of the n8n UI: the overview dashboard, workflow canvas, project cards, execution statistics, sidebar, and animated insight circles. n8n Theme List: - Black & White — Monochrome n8n UI (FREE) - Warm Glow — Amber-toned n8n interface (FREE) - Cyberpunk — Neon pink-purple n8n dark theme (PRO) - Radiation Reactor — Toxic green n8n theme with animated orbital stat rings (PRO) - Sea Side Dev — Aqua and cyan n8n canvas (PRO) - Aurora Synth — Deep purple n8n dark mode (PRO) - Crimson Velvet — Deep red n8n dark theme (PRO) - Gold Dawgs — Warm amber n8n UI (PRO) - Pink Rose — Magenta-rose n8n interface (PRO) Switch n8n themes in one click.
