Wife‑Approved Self‑Hosted Finance Apps: Real Reddit Verdicts & Step‑by‑Step Setup

The Community Spark: Why “Wife‑Approved” Became a Reddit Hot Topic #

In early 2026 a post titled “Wife approved Self Hosted finance app” blew up on r/selfhosted. The OP (a full‑stack dev) confessed that every open‑source budgeting tool he tried looked like a hacker’s spreadsheet—until his partner balked at the UI. The thread quickly morphed into a broader conversation: Can a self‑hosted finance manager be both secure and user‑friendly enough for a non‑technical spouse?

Search traffic confirms the pain point—Google Trends shows a 250 % spike in queries for “self hosted budgeting app for couples” over the past three months. That’s why this guide leans on real community experiences, not just feature lists.

Synthesized Community Perspectives: What the Redditors Actually Said #

The Debates #

1. Firefly III vs. Money Manager Ex (MME)

   • Firefly III won the “feature completeness” vote (multi‑currency, scheduled transactions, API).
   • MME got love for its desktop‑first design, but many complained about its limited web UI.

2. Budgea (self‑hosted API) + Front‑ends

   • Some tech‑savvy users built a custom React front‑end, calling it “wife‑approved” only after months of work—most deemed it overkill.

3. KMyMoney (Qt) on a Raspberry Pi

   • Praised for native feel, yet the lack of native mobile sync was a deal‑breaker for couples who budget on the go.

Bottom line: The community converged on Firefly III running in Docker with a reverse‑proxy as the most balanced solution—robust features, decent UI, and an official mobile app.

Deep‑Dive Actionable Guide: Installing the “Wife‑Approved” Firefly III Stack #

Below is a battle‑tested, production‑ready setup that a Reddit user (u/tech‑dad‑42) used on a 2 CPU 2 GB VPS running Ubuntu 22.04. It covers Docker, HTTPS, automated backups, and a quick UI walkthrough.

1️⃣ Prerequisites #

# Update system & install Docker + Compose
sudo apt update && sudo apt upgrade -y
sudo apt install -y ca-certificates curl gnupg lsb-release

# Docker repo
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] \
  https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

# Verify
docker version
docker compose version

2️⃣ Create a Dedicated Docker‑Compose Project #

mkdir -p ~/firefly
cd ~/firefly

Create a .env file (never commit it to git):

# .env
POSTGRES_USER=firefly
POSTGRES_PASSWORD=SuperSecret123!
POSTGRES_DB=firefly
FIRELY_VERSION=latest
TZ=Europe/Paris          # Adjust to your timezone

Now, docker-compose.yml:

version: "3.9"

services:
  db:
    image: postgres:15-alpine
    restart: unless-stopped
    environment:
      POSTGRES_USER: ${POSTGRES_USER}
      POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
      POSTGRES_DB: ${POSTGRES_DB}
    volumes:
      - db_data:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U ${POSTGRES_USER}"]
      interval: 10s
      timeout: 5s
      retries: 5

  firefly:
    image: fireflyiii/core:${FIRELY_VERSION}
    restart: unless-stopped
    depends_on:
      db:
        condition: service_healthy
    environment:
      - APP_ENV=production
      - DB_CONNECTION=pgsql
      - DB_HOST=db
      - DB_DATABASE=${POSTGRES_DB}
      - DB_USERNAME=${POSTGRES_USER}
      - DB_PASSWORD=${POSTGRES_PASSWORD}
      - TZ=${TZ}
      - TRUSTED_PROXIES=*
      - APP_URL=https://budget.example.com
    ports:
      - "8080:8080"
    volumes:
      - firefly_uploads:/var/www/html/storage/upload
    healthcheck:
      test: ["CMD", "wget", "-qO-", "http://localhost:8080"]
      interval: 30s
      timeout: 10s
      retries: 5

  caddy:
    image: caddy:2-alpine
    restart: unless-stopped
    depends_on:
      - firefly
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - caddy_data:/data
      - caddy_config:/config
      - ./Caddyfile:/etc/caddy/Caddyfile
    environment:
      - TZ=${TZ}

volumes:
  db_data:
  firefly_uploads:
  caddy_data:
  caddy_config:

3️⃣ Caddy Reverse‑Proxy + Automatic HTTPS #

Create Caddyfile in the same directory:

budget.example.com {
    reverse_proxy firefly:8080
    encode gzip
    header {
        Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
        X-Content-Type-Options "nosniff"
        Referrer-Policy "strict-origin-when-cross-origin"
    }
}

Caddy will obtain a free Let’s Encrypt certificate the first time you start the stack.

docker compose up -d

Tip: If you’re behind Cloudflare, enable “Full (strict)” SSL and add the origin certificate to Caddy’s trusted store.

4️⃣ Initial Firefly III Setup (First‑Run Wizard) #

1. Open https://budget.example.com in a browser.
2. Choose “Create a new account” → set an admin password (share this with your spouse).
3. Select “SQLite (default)” – the wizard will automatically switch to PostgreSQL because we defined DB_CONNECTION=pgsql.
4. Pick “Euro” (or your local currency) and hit Finish.

UI Walk‑through for the non‑technical partner

5️⃣ Mobile Access – The Official Android App #

Firefly III offers an open‑source Android client (app.firefly-iii.org). Install it from the Play Store or F-Droid, then configure:

• Server URL: https://budget.example.com/api/v1
• Personal Access Token: Generate one under Profile → API Tokens inside the web UI.
• Sync frequency: Every 6 hours (adjustable).

The iOS community uses Firefly III Companion (available on TestFlight) – the same token works.

6️⃣ Automated Backups (Restic + Cron) #

# Install Restic
sudo apt install -y restic

# Initialize repository (e.g., remote S3 bucket)
export RESTIC_REPOSITORY=s3:s3.amazonaws.com/your-bucket/firefly-backups
export RESTIC_PASSWORD=AnotherSuperSecret!

restic init

Create a backup script ~/firefly/backup.sh:

#!/bin/bash
set -euo pipefail
export RESTIC_REPOSITORY=s3:s3.amazonaws.com/your-bucket/firefly-backups
export RESTIC_PASSWORD=AnotherSuperSecret!

# Dump PostgreSQL
docker exec firefly-db pg_dump -U ${POSTGRES_USER} ${POSTGRES_DB} > /tmp/firefly.sql

# Backup both DB dump and uploads
restic backup /tmp/firefly.sql /home/$(whoami)/firefly/firefly_uploads

# Clean temporary dump
rm /tmp/firefly.sql

# Forget old snapshots (keep last 7 daily, 4 weekly, 6 monthly)
restic forget --keep-daily 7 --keep-weekly 4 --keep-monthly 6 --prune

Add to cron (run nightly at 02:00):

0 2 * * * /home/youruser/firefly/backup.sh >> /var/log/firefly_backup.log 2>&1
