B-FAST Inspector

Ultra-fast B-FAST binary protocol inspector, JSON decoder, and bandwidth optimizer proof-card generator for DevTools.

⚡ B-FAST Inspector — Official Chrome DevTools Extension for the B-FAST Binary Protocol Eliminate "DevTools blindness" when working with ultra-fast binary payloads. B-FAST Inspector lets you inspect, decode, visualize, and benchmark B-FAST responses in real time directly inside Chrome DevTools. ══════════════════════════════════════════════════════════════ 📦 COMPATIBILITY & ECOSYSTEM (Python & TypeScript) ══════════════════════════════════════════════════════════════ B-FAST Inspector works seamlessly with the official B-FAST libraries: • Python (Backend): Available on PyPI (pip install b-fast) Native Rust-powered engine with drop-in integrations for FastAPI, Django, Flask, and Starlette. • TypeScript / JavaScript (Frontend): Available on NPM (npm install bfast-client) Zero-allocation client decoder with WebAssembly acceleration and TanStack Query support. ══════════════════════════════════════════════════════════════ 🚀 10-SECOND QUICKSTART ══════════════════════════════════════════════════════════════ Backend (FastAPI / Python): from fastapi import FastAPI from b_fast.fastapi import BFastMiddleware app = FastAPI() app.add_middleware(BFastMiddleware) # Automatically serves binary to compatible clients Frontend (Browser / TypeScript): import 'bfast-client/auto'; // Automatically handles negotiation and transparent decoding // Your standard fetch calls now transparently receive B-FAST binary! const res = await fetch('/api/telemetry'); const data = await res.json(); Open Chrome DevTools (F12), click the "⚡ B-FAST" tab, and watch your requests appear with real-time compression metrics! ══════════════════════════════════════════════════════════════ 🌟 KEY FEATURES ══════════════════════════════════════════════════════════════ 1. 🔍 Zero-Config Network Interception: Automatically intercepts all HTTP/HTTPS requests returning application/x-bfast headers without requiring any manual setup. 2. ⚡ Sub-Millisecond In-Browser Decode: Decodes binary B-FAST compressed payloads instantly into native JavaScript objects using the high-performance B-FAST engine, with real-time microsecond-level timing benchmarks. 3. 🌳 Interactive JSON Tree Viewer: Browse deeply nested objects and arrays just like native DevTools. Features instant live search, key/value filtering, and one-click expand/collapse. 4. 🔬 Raw Hex Dump Inspector: Inspect byte-level structures, verify endianness, examine metadata headers, and validate bytes. 5. 📸 The Optimization Proof Card Generator: Generate high-impact, 16:9 retina social proof cards (1200x675) showing your real bandwidth savings (-80% to -92%) and client decode latency. Ready to copy directly to your clipboard or download as PNG for sharing with team members, PRs, Twitter/X, and LinkedIn. 6. 🧪 Built-in Demo Sandbox: Test all features without needing a local backend running by clicking "⚡ Demo Request" in the top bar. ══════════════════════════════════════════════════════════════ 🔒 PRIVACY & ZERO DATA COLLECTION ══════════════════════════════════════════════════════════════ • 100% Client-Side: All decoding and rendering happen entirely inside your local DevTools panel. • No External Tracking: Zero analytics, zero telemetries, zero third-party scripts. • No Injected Scripts: Does not inject content scripts or modify webpage DOM contexts. • Minimal Footprint: Requests zero elevated permissions. ══════════════════════════════════════════════════════════════ 🔗 OFFICIAL LINKS & ATTRIBUTION ══════════════════════════════════════════════════════════════ Created by Marcelo Markus.
