Snippit - Snippet Injector

Inject JS, CSS, HTML, JSON, TypeScript, YAML, XPath etc. and custom scripts into any website for testing and debugging.

Snippit is a developer tool for injecting and testing code snippets directly on any webpage — without leaving the browser. Write JavaScript, CSS, HTML, JSON, GraphQL, fetch requests, and more in a built-in editor, then run them on the current tab in one click. Built for QA engineers, frontend developers, and anyone who debugs live sites. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY SNIPPIT? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Test fixes and experiments on production-like pages instantly • Override styles, inject mock data, and probe DOM behavior safely • Keep a personal library of reusable snippets with tags, search, and favorites • No separate app, no account required — your data stays in your browser ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CORE FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ EDITOR & INJECTION • Multi-language tabs: JS, CSS, HTML, JSON, TypeScript, GraphQL, Fetch/API, YAML, XPath, JWT, CSV, SQL, Regex, Userscripts, and custom languages • Syntax highlighting, find/replace, format, minify, undo/redo, and word wrap • Inject into this tab or all tabs on a domain with URL pattern matching • Per-tab undo stack — revert your last injection • Live CSS preview and destructive-action warnings before risky injects • 370+ built-in templates for audits, mocks, ecommerce, and debugging DEBUGGING & CONSOLE • Dockable console panel (bottom, left, or right) with resize handle • Filter logs by level (error, warn, log) and search console output • Copy or export console output • Element picker — click any element to get CSS, XPath, Playwright, and Cypress selectors • Fetch & GraphQL runners with request history and tab cookies support • Fetch mock runtime and auto-inject triggers (element visible, fetch match) LIBRARY & WORKFLOW • Save snippets with name, description, tags, and version history • Pin, archive, duplicate, and share snippets via clipboard • Injection history with load, copy, and re-inject • Quick picker (Ctrl+Shift+K) to find and run saved snippets fast • Run ordered sequences with per-step delays; export to Playwright .spec.js • Git-friendly export (.snippit/ bundle) and full workspace backup/import TEAM & LOCAL GOVERNANCE (no cloud account) • Org library export/import for sharing snippet packs offline • Approved-snippet gate and local audit log (export/clear) • Sync pack backup reminder — all storage is local unless you export files yourself ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ USEFUL KEYBOARD SHORTCUTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Ctrl+Shift+J — Toggle Snippit panel • Ctrl+Shift+K — Quick picker (snippets & templates) • Ctrl+Shift+I — Inject current snippet • Ctrl+Shift+Y — Re-inject last snippet • Ctrl+Enter — Inject from editor (Mac: use Command instead of Ctrl) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IS THIS FOR? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Snippit is intended for developers and testers working on their own sites, staging environments, or with explicit permission.
