URL Editor Pro

Edit URL parameters, switch environments, decode JWT/Base64, run regex rewrites, and strip trackers — fully offline.

URL Editor Pro is a developer-focused toolkit for inspecting, editing, and rewriting URLs in your browser — without leaving the page or sending data to a server. Built for engineers, QA, marketers, and anyone who works with URLs every day. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT YOU CAN DO ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📝 Edit any URL parameter inline • Type-aware editing: numbers get a stepper, booleans a toggle, dates a calendar, lists a tag editor • Auto-detects JWTs and Base64 in parameter values • Add, remove, or rename parameters and apply with one click • Live diff view showing exactly what changed before you navigate 🧹 One-click URL sanitizer • Strip utm_source, utm_medium, utm_campaign, fbclid, gclid, msclkid, ttclid, igshid, mc_cid, dclid, and 25+ other tracking parameters • See exactly which params got removed before applying 🌐 Environment switcher (dev → staging → prod) • Define groups of equivalent domains (e.g., localhost:3000, staging.api.io, api.io) • Switch the active environment from the popup; matching URLs are automatically rewritten across the entire browser • Works for subdomains too — *.staging.api.io rewrites to *.api.io 🔍 Regex rules engine (declarativeNetRequest-powered) • Append, replace, or remove URL parameters via regex matchers • Replace whole URLs with backref support (\1, \2, …) • Up to 5,000 dynamic rules per profile • Test rules against any URL before saving • Built-in presets: Force HTTPS, Remove UTM, Reddit Sort by New, Replace Domain • Export and import rules as JSON to share with your team 🔐 JWT & Base64 inspector and builder • Auto-decode JWTs and Base64 found in URL parameters • Inspect JWT header, payload, expiry, and signature segment • Build new JWTs with real HS256, HS384, or HS512 signing (uses Web Crypto) • Encode and decode arbitrary Base64 (UTF-8 safe) 🧾 QR code generator • Single QR for the current URL or any custom URL • Batch mode: paste a list, get a ZIP of SVGs back • Color customization (foreground & background) • Optional center logo overlay • Live URL preview, adjustable size 📒 Annotations • Attach notes to specific URL parameters or domains • Built-in glossary of 30+ tracking and analytics parameters • Sees what tag, fbclid, gclid, irclickid, ttclid, etc. actually mean ⚡ Power-user features • Cmd+K / Ctrl+K command palette — every action one keystroke away • URL history panel — restore any of the last 25 URLs you visited or edited • Optional cross-device sync via your Chrome account (rules and environments) • 5-language support: English, Spanish, Japanese, Korean, Chinese ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY-FIRST DESIGN ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ URL Editor Pro runs entirely offline. We do not have a server. We do not send your URLs, rules, JWTs, annotations, or any other data anywhere. • No account, no signup, no telemetry • No ads, no trackers • Your data lives in chrome.storage on your own device • Optional sync uses Chrome's built-in account sync — never our infrastructure • Open about every permission we request — see the manifest ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Backend & full-stack developers debugging API calls and OAuth flows • QA engineers running the same test across environments • Affiliate marketers inspecting and cleaning campaign URLs • Privacy-minded users who want share-clean URLs • Anyone who has ever wished they could just edit a query parameter ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEYBOARD SHORTCUTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Cmd+K / Ctrl+K — Open the command palette from any tab • Esc — Close any panel or palette ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PERMISSIONS — WHAT EACH ONE DOES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • declarativeNetRequest — runs your regex rules inside Chrome's rule engine. We never see the URLs that match • declarativeNetRequestFeedback — surfaces rule matches in the dev console (debugging only, unpacked builds) • storage — saves your rules, environments, annotations, and history locally • tabs — reads the URL of the active tab so you can edit it • webNavigation — re-applies rules to URLs served from the back/forward cache • <all_urls> — required by Chrome so your rules can match any site you visit. We never read page contents We do NOT use: ✗ scripting (no content scripts, no page injection) ✗ contextMenus (no right-click items) ✗ identity, cookies, history, browsingData, or any other privacy-sensitive API ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT'S NEW IN 1.4.0 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Real HMAC-SHA256/384/512 JWT signing via Web Crypto • One-click URL sanitizer (strip 30+ tracking parameters) • Live parameter diff view • URL history with one-click restore • Cmd+K command palette • Rule export/import as JSON • Batch QR codes with color, logo, and ZIP download • Cross-device sync of rules and environments • Settings panel • Localized for English, Spanish, Japanese, Korean, Chinese • Hardened security: sender validation, scheme checks on navigation, ReDoS guard on user regex, CSP ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Made by dealsgroup®.
