Turnkey offline-first PWA for custom vehicle build provenance & field triage.
B-Pillar is an offline-first Progressive Web App (PWA) built for custom automotive restomod shops, chassis fabricators, and overland upfitters. It solves the costly "orphan build" problem by locking bespoke donor parts, torque tolerances, and fluid capacities into an immutable digital ledger accessible via door-jamb QR data plates. Why Buy This Asset? Custom builders assemble six-figure vehicles with non-OEM drivetrains and custom routings. Once sold, records disappear, resulting in endless unbillable support calls years later. B-Pillar provides a complete, turnkey solution that a buyer or digital agency can re-sell directly to a custom shop or productize as a niche automotive SaaS. Core Features: 30-Second Autoplay Simulation: Interactive landing demo that demonstrates the full lifecycle from fabrication to field triage without friction. Shop Mode (In-Bay Logging): PIN-secured entry for mechanics to log donor SKUs, casting numbers, fluid specs, and torque tolerances. SHA-256 Cryptographic Handover: One-click generation of an immutable digital certificate of build provenance for auctions and private sales. Zero-Login Field Triage: End-users or trail mechanics scan the physical B-pillar QR tag for instant offline access to cross-reference numbers (Gates, NAPA). Includes one-tap "Trail Recovery" filtering for belts, seals, and filters. Physical Asset Generation: In-app vector export (.svg / .png) sized for laser-etching physical aluminum data plates. Tech Stack & Codebase Quality: Built with React, Tailwind CSS, and Lucide Icons. Pure zero-login, client-first PWA architecture with zero PII exposure and complete offline persistence. Clean, unencumbered codebase: zero legacy strings, completely decoupled, ready for standalone Vite/React hosting (or continue on Base44). What's Included in the Sale: 100% full unencumbered IP ownership and source code repository. Vector asset templates (.svg) for physical laser-etched B-pillar tags. Complete technical documentation and build provenance dossier templates. Direct repository transfer with zero ongoing dependencies or obligations.
Next step: <p>1. Direct Builder Sales: Package and resell the system directly to boutique custom restomod shops (ICON, Singer, overland fabricators) for $5,000–$15,000 as a premium customer handover feature.</p><p>2. B2B SaaS Rollout: Wrap multi-tenant user accounts with a backend to charge shops $49–$199/month for fleet build logging and digital certificate hosting.</p><p>3. Turnkey Physical Tag Fulfillment: Partner with a laser-etching vendor to dropship custom anodized aluminum B-pillar plates with every digital build pack ($150–$300 per vehicle tag package).</p><p>4. Auction Integration: Partner with boutique automotive auction platforms (Bring a Trailer, Cars & Bids) to offer verified cryptographic provenance dossiers.</p><p>```[cite: 22]</p>
