Easy Local Storage Manager - IndexedDB Viewer & Editor

Edit localStorage, cookies & IndexedDB as JSON. Lock keys, track changes, switch profiles. AI agents can now edit it over MCP.

Easy Local Storage Manager is a developer tool that lets you view and edit localStorage, sessionStorage, cookies and IndexedDB for any site as a searchable JSON tree — no more squinting at the default Application panel. WHAT'S NEW IN 3.2.7 — YOUR AI AGENT CAN NOW WORK WITH REAL STORAGE This release ships an MCP (Model Context Protocol) bridge, so any MCP-capable AI coding agent can read and write the storage of the tab you are working on. No more pasting storage dumps into chat. 🤖 Connect in one command — npx -y @elsm/mcp, paired with a token from the sidebar's Agent Access page. Step-by-step setup for every client: https://easylocalstorage.dev/docs 👥 Connected Agents screen — every agent that has called in, with last used, total calls and last action. Block or revoke one in a click. 🧾 Full audit trail — every agent write lands in the change log alongside its stack-trace entry, exactly like a page write. 🔒 Local-only by design — the bridge listens on 127.0.0.1 only, every connection must present the pairing token first, and cookie values stay redacted until you explicitly allow raw values. 📋 Clear plan limits — agents can read on the Free plan (50 calls a day); writing or deleting through an agent requires Pro. Also improved in 3.2.7: edits made from the sidebar now travel through the same lock-aware write channel as the page itself, so your per-key locks and the change log capture extension-originated edits instead of bypassing them. WHY DEVELOPERS CHOOSE EASY LOCAL STORAGE MANAGER: 🚀 Smart JSON Editor — Stop parsing raw strings manually. View and modify LocalStorage, SessionStorage, Cookies, and IndexedDB as structured JSON/Tree objects. Edit keys and values with syntax highlighting and validation. 🔒 Per-Key State Locking — Lock any localStorage or sessionStorage key to prevent accidental writes. Perfect for protecting critical configuration values, feature flags, or authentication tokens during development. 🕵️ Change Tracking with Stack Traces — See exactly who changed a value and where in your code. Every mutation to localStorage, sessionStorage, and cookies is logged with the full call-site stack trace - invaluable for debugging unexpected state changes. 👤 Store User Profiles Locally — Save and switch between multiple user profiles with different storage states. Test different user scenarios, permissions, or configurations instantly without manual setup. ☁️ Cloud Sync (Pro) — Seamlessly sync your storage data across multiple devices. Keep your development environment consistent between work and home machines. Sync is optional and uses End-to-End Encryption to ensure your sensitive tokens remain private. 🔐 JWT Toolkit — Debug authentication flows faster. Decode, verify, and inspect JWT headers, payloads, and signatures directly within the extension—no need to paste tokens into external websites. 🔍 Deep Search — Find exactly what you're looking for. Instantly search for keys or values buried deep within complex nested JSON objects. 📂 Import & Export — Never lose your setup. Backup your entire storage state to JSON files or restore them later to reproduce bugs and share configurations with your team.
