🚗 Roadlog

A self-hosted vehicle expense tracking system. Track fuel fill-ups, other expenses, and monitor consumption across all your vehicles.

Why Roadlog?

I've long liked the idea behind self-hosted vehicle trackers, but a handful of annoyances (some I hit with tools like Hammond) kept bugging me — so I built my own take and fixed those rough edges the way I wanted. The other driver was EVCC: I run it at home for solar charging, so first-class EVCC integration was something I wanted baked in from the start.

It's a single self-hosted container (Go + embedded frontend + SQLite) — nothing external to run. Not trying to replace anything; just a scratch-my-own-itch project that others might find useful. PRs and suggestions are very welcome.

Features

• Multi-vehicle support — petrol, diesel, LPG, CNG, electric, hybrid, plugin hybrid
• Plugin Hybrid — choose fuel or electric per fill-up
• EVCC integration — auto-import home charging sessions with solar %, actual cost from dynamic tariffs, and savings vs grid
• Vehicle lifecycle — mark vehicles as inactive (won't appear in new entries) or hide from stats
• Smart fill-up form — pre-fills last odometer, price, and station (configurable), plus per-station price memory (remembers the last price you paid at each saved station)
• Saved stations — per fuel type, with autocomplete suggestions
• Other expenses — insurance, service, repair, tires, parking, tolls, etc.
• Dashboard — grouped per-vehicle bars (side-by-side comparison), Cost/Distance view, per-month or per-day buckets, cost-type breakdown (fuel/expense), clickable per-vehicle legend, and period filters
• History — a single filterable log of all fill-ups and expenses across every vehicle: filter by type, car, station, period, price and volume
• Per-vehicle charts — consumption and price trends, plus an EV solar/grid monthly charging chart, all with a month/day toggle
• Multi-user — shared vehicles, user management
• CSV import — with smart column mapping and auto-guess
• CSV export & full backup/restore, plus scheduled auto-backup to WebDAV/local
• Responsive UI — mobile layout or a desktop sidebar, with a manual view toggle
• Theme — light, dark, or auto (follows the OS)
• Configurable units & formats — currency (EUR, USD, GBP, CZK, PLN…), volume (L, gal), distance (km, mi), and date format (DD/MM/YYYY, MM/DD/YYYY, YYYY-MM-DD…)
• Single container — Go backend + embedded frontend, SQLite database

EVCC Integration

Automatically import EV charging sessions from EVCC with full solar/cost data.

Setup:

1. Go to your EV's edit page → EVCC Integration section
2. Enter your EVCC instance URL (e.g. http://192.168.x.x:7070)
3. Click "Connect & Discover" — select vehicle and loadpoint
4. Set a label (e.g. "Home"), sync-since date, and optionally enable daily auto-sync
5. Set a fallback price for sessions without tariff data (estimates cost using solar %)

What gets imported:

• Charged energy (kWh)
• Actual cost (from dynamic tariffs, accounting for solar share)
• Solar percentage per session
• Odometer reading
• Savings vs full grid price

Deduplication: Sessions are tagged with their EVCC session ID — re-syncing never creates duplicates.

Multiple sources: You can add multiple EVCC instances per vehicle (e.g. home + parents' house).

Automatic Backup

Roadlog can automatically back up your data to WebDAV (Nextcloud) or a local path on a configurable schedule.

Configure in Settings → Automatic Backup.

Schedule Options

• Daily — runs at a specific time (default 03:00)
• Weekly — runs on a chosen day of the week at a specific time
• Monthly — runs on a chosen day of the month (1–28) at a specific time

WebDAV (Nextcloud) Setup

1. In Nextcloud, create a folder for backups (e.g. Backups/Roadlog)
2. Go to Settings → Security → Devices & sessions
3. Enter a name (e.g. "Roadlog") and click Create new app password
4. Copy the generated token

In Roadlog settings:

• Type: WebDAV (Nextcloud)
• URL: https://your-cloud.com/remote.php/dav/files/YOUR_USERNAME/Backups/Roadlog/
• Username: your Nextcloud username (found in Settings → Personal info)
• Password: the app password token from step 3

💡 Use an app password instead of your main password — it bypasses 2FA and can be revoked independently.

Local Path

Set a directory path (e.g. /backups/roadlog). Mount a volume to that path in Docker:

volumes:
  - ./data:/data
  - /mnt/nas/backups/roadlog:/backups/roadlog

Roadlog will write timestamped JSON backups and auto-clean old ones based on your retention setting.

Options

You can also click Run Now to trigger a backup manually.

Quick Start

Unraid

1. In Unraid, go to Docker → Template Repositories
2. Add: https://github.com/stomko11/roadlog
3. Click Add Container, select the Roadlog template
4. Click Apply — done!

Data is stored in /mnt/user/appdata/roadlog by default.

Docker Compose

services:
  roadlog:
    image: stomko11/roadlog:latest
    container_name: roadlog
    ports:
      - "3000:3000"
    volumes:
      - ./data:/data
    restart: unless-stopped

docker compose up -d

Open http://localhost:3000

Default credentials: admin@roadlog.local / roadlog

⚠️ Change the default password after first login.

Alternative registries

• Docker Hub: stomko11/roadlog:latest
• GitHub Container Registry: ghcr.io/stomko11/roadlog:latest

Environment Variables

Build from Source

Requirements: Go 1.22+

cd backend
go mod tidy
go build -o roadlog .
DATA_DIR=. ./roadlog

Open http://localhost:3000

Tech Stack

• Backend: Go, Gin, GORM, SQLite
• Frontend: Vanilla JS (embedded single HTML file)
• Container: Alpine Linux (~20MB)

Development

cd backend
DATA_DIR=. go run main.go

The frontend is embedded in backend/static/index.html. Changes require rebuilding the Go binary.
