ddpc

The Garage OS

A platform for people who actually care about their vehicles. Not another mileage tracker or reminder app. A full operating system for your garage. Fuel economy that reveals real patterns. Maintenance history that builds trust. Build documentation that tells the story of what you've created. An AI that knows your vehicles as well as you do.

The Problem

Car people keep everything in their heads. Fuel logs in a notes app. Maintenance records in a glovebox folder. Mod lists on forum threads. Service history scattered between three shops that don't talk to each other. When it's time to sell, there's no way to prove the care you've put in. When something breaks, there's no timeline to trace back through.

The tools that exist are either glorified spreadsheets or insurance company data grabs. Nothing built by someone who actually spends weekends in the garage.

ddpc is what I wanted to exist and couldn't find.

What It Does

Everything your garage needs in one place. Built for enthusiasts, not insurance companies.

Fuel Tracking

Log every fill-up. See your real cost per mile, consumption trends over time, and how driving habits or modifications actually affect efficiency. No more guessing — just data.

Vehicle Health Insights

Maintenance schedules, full service history, and intelligent reminders based on your actual mileage and driving patterns. Know what your vehicle needs before it tells you the hard way.

Build Tracking

Document every mod, every part, every project. Track what you installed, when, and what it cost. Your build history lives in one place — not scattered across forum posts and receipts.

Shop Trust

Transparent service records that connect owners and shops. Shops build reputation through documented work. Owners get verified history they can trust. Both sides win.

Private Sale Confidence

A documented vehicle history — fuel logs, maintenance records, mod list — gives buyers real confidence and gives sellers the premium their care deserves. Trust built on data, not promises.

Garage Keep — Your AI

An in-app AI assistant that knows your vehicles, your service history, and your build plans. Ask it anything — from torque specs to maintenance intervals to what that dashboard light means.

Under the Hood

ddpc is a full-stack application. Designed, built, and operated by one person. The frontend, the backend, the database architecture, the AI integration, the email pipeline, the payment system, the data products. Every layer.

This isn't a weekend project or a template with a logo on it. It's a production platform handling real user data, processing shop emails into structured service records, running an AI assistant that understands vehicle specifications across 100K+ records, and managing a shop network that connects owners with the businesses that service their vehicles.
