OPEN-SOURCE LOCALHOST SANDBOX & CLOUD DEPLOYER β€’ Β© 2026 SRP Hub (srphub.in)

Check it on localhost before it goes to cloud.

Build, harden, smoke-test, and inspect line-by-line code diffs in an isolated ephemeral sandbox without ever polluting your source folder with node_modulesβ€”then push to GitHub and stream Cloudflare Pages builds in one click.

Engineered for Zero-Footprint Local Testing

Built from the ground up to keep your source repositories clean, catch runtime bugs before deployment, and manage multi-account cloud releases effortlessly.

πŸ”’

100% Read-Only Source Protection

Keep your project folders inside Google Drive, OneDrive, or local Git repos without ever installing 15,000+ node_modules files inside them. Packages are cached inside your isolated sandbox drive and linked in 0.05 seconds via Windows Junctions.

πŸ“

Rolling Baseline & Line-by-Line Diff

Automatically snapshots your working code state without requiring Git. Inspect exact red/green line-by-line code changes between builds, and automatically promote your current state to the new baseline when a cloud deployment succeeds.

πŸ›‘οΈ

Pre-Flight Guard & Route Smoke Tester

Scans for exposed API keys, tokens, merge conflict markers (<<<<<<< HEAD), and debugger; statements before compilingβ€”then crawls every built HTML page to verify all local scripts, stylesheets, and images resolve cleanly.

πŸ“₯

AI-Ready .md Diagnostic Exporter

Captures compiler error blocks, live preview JavaScript stack traces, unhandled promise rejections, missing 404 assets, and bundle size audits into a structured Markdown report ready to drop into any AI coding assistant.

πŸ”

DPAPI-Encrypted Multi-Project Vault

Work across multiple repositories, GitHub accounts, and Cloudflare Pages projects seamlessly. Each project's credentials are encrypted locally using Windows Data Protection API (ProtectedData) bound to your OS login.

☁️

Live Cloudflare Stream & 1-Click Retry

Push to GitHub and stream real-time Cloudflare Pages build stages directly inside the Studio window. If a transient cloud build fails, trigger an immediate Cloudflare API deployment retry or export the cloud failure log as .md in one click.

Up and Running in 60 Seconds

Use the modular open-source repository or generate a single self-contained portable .bat file to carry to any Windows PC.

STEP 1

Launch & Pick Your Sandbox

Double-click Launch-Studio.bat (or the Portable single-file edition). On first boot, choose your isolated Sandbox folder and optional Desktop / Start Menu shortcuts.

STEP 2

Run a Local Dry Run

Click any detected repository card or drag-and-drop a project folder. Test responsive Desktop, Tablet, and Mobile viewports while the Studio monitors for runtime JS or 404 errors.

STEP 3

1-Click Cloud Deploy & Auto-Wipe

Switch to Cloud Deploy to push to GitHub and track Cloudflare Pages live. When finished, click Close & Wipe to clean up all temporary build files automatically.
