SuperDev Pro

One extension that replaces all your browser tools — inspect, design, modify, capture, scrape, automate, and more in a sidebar.

SuperDev Pro packs 50+ developer, designer, marketer, and power-user tools into a single keyboard-driven sidebar. Stop hoarding one-off extensions — open one sidebar, get everything. ⌨️ Open with Ctrl+Shift+E (Cmd+Shift+E on Mac). Hit Ctrl+Shift+S for the command palette and jump straight to any tool. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ INSPECT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • CSS Inspector — live styles + computed values, copy any rule • Layout Tools — box model, flex/grid overlays, parents/children • Ruler & Measure — click two points: distance, angle, ΔX/ΔY • Color Picker — eyedrop + history + HEX/RGB/HSL • Color Palette — extract every color used, highlight where it appears • Site Stack — detect frameworks, CMS, analytics, CDN, server • SEO Meta — full on-page audit: meta, social, headings, images, links • Page Speed — Core Web Vitals, resources, page weight • Accessibility — contrast, alt text, ARIA, headings, labels • AI Assistant — BYOK chat over any OpenAI-compatible API with page context ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ DESIGN & MODIFY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Font Changer — pick element, 50+ Google Fonts, live preview • List Fonts — detect every font on the page, highlight usage • Pattern Background — 8 patterns, presets, copy CSS • Dark Mode — force dark on any site, per-domain control • Code Injection — JS / CSS / HTML per-domain with snippet library • Live Text Editor — click to edit, track changes, export HTML • Image Replacer — drop file or URL, persists across reloads • Move / Delete Element, Page Outliner — surgical DOM tweaks ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CAPTURE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Screenshot — visible, area selection, or full-page (JPG / PNG) • Save as PDF — live preview, A4 / Letter, custom margins • Table Capture — every table on the page to CSV / TSV / JSON / Markdown • Export Element — pick any element, send HTML + matched CSS to CodePen ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ DATA ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Web Scrape — auto-detect lists & tables, scrape, export • API Tester — any origin, CORS-free, request history • URL Opener — bulk-open URLs with pause / stop control • Extract Images — img + background + SVG + favicon + og, bulk download • Broken Link Checker — parallel HEAD checks, live progress, CSV • Webpage → Markdown — page / main / picked element to GFM • Stripe Analytics — charges, MRR, refunds, breakdowns • Subreddit Insights / User Analyzer / Cross-Post Finder — full Reddit toolkit ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WORKFLOW ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Todo — per-site task list • Sticky Notes — drop notes anywhere, drag, 6 colors, per-site persist • Tab Manager — list, filter, bulk close / copy / move • UTM Builder — campaign URLs with templates and custom params ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ BROWSER ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Cookie Editor — list, search, add, edit, export cookies • Clear Browsing Data — this site or all, 11 categories, time-range • Redirect Path — trace full chain with status + headers ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ UTILITY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Currency Converter — live FX, detect amounts on page, 30+ currencies • Email Finder — scan text, mailto, obfuscated, group by domain • QR Code — URL, vCard, Wi-Fi, custom color, embedded logo • JSON Formatter — format, minify, sort keys, validate • Encoder / Decoder — Base64, URL, HTML, hex, Unicode, MD5 / SHA • World Clock — multi-timezone with floating widget ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Everything runs locally in your browser.
