# Fredy 🏡 – Your Self-Hosted Real Estate Finder for Germany

Finding an apartment or house in Germany can be stressful and
time-consuming.\
**Fredy** makes it easier: it automatically scrapes **ImmoScout24,
Immowelt, Immonet, eBay Kleinanzeigen, and WG-Gesucht** and notifies you
instantly via **Slack, Telegram, Email, ntfy, and more** when new
listings appear.

With a modern architecture, Fredy provides a **clean Web UI**, removes
duplicates across platforms, and stores results so you never see the
same listing twice.

## 🧩 Core Concepts

Fredy is built around three simple concepts:

### Provider 🌐

A **provider** is a real-estate platform (e.g. ImmoScout24, Immowelt,
Immonet, eBay Kleinanzeigen, WG-Gesucht).\
When you create a job, you paste the search URL from the platform into
Fredy.\
⚠️ Always make sure the search results are sorted by **date**, so Fredy
picks up the newest listings first.

### Adapter 📡

An **adapter** is the channel through which Fredy notifies you (Slack,
Telegram, Email, ntfy, ...).\
Each adapter has its own configuration (e.g. API keys, webhook URLs).\
You can use multiple adapters at once --- Fredy will send new listings
through all of them.

### Job 📅

A **job** combines providers and adapters.\
Example: "Search apartments on ImmoScout24 + Immowelt and send results
to Slack + Telegram."\
Jobs run automatically at the interval you configure (see
`/conf/config.json`).

------------------------------------------------------------------------

## Immoscout

Immoscout has implemented advanced bot detection. In order to work around this, we are using a reversed engineered version of their mobile api. See [Immoscout Reverse Engineering Documentation](https://github.com/orangecoding/fredy/blob/master/reverse-engineered-immoscout.md)

## Analytics

Fredy is completely free (and will always remain free). However, it would be a huge help if you’d allow me to collect some analytical data.
Before you freak out, let me explain...  
If you agree, Fredy will send a ping once every 6 hours to my internal tracking project (Will be open sourced soon).  
The data includes: names of active adapters/providers, OS, architecture, Node version, and language. The information is entirely anonymous and helps me understand which adapters/providers are most frequently used.</p>

**Thanks**🤘

## 🛠️ Development

### Development Mode

``` bash
yarn run start:backend:dev
yarn run start:frontend:dev
```
You should now be able to access _Fredy_ from your browser. Check your Terminal to see what port the frontend is running on.

### Run Tests

``` bash
yarn run test
```
