Take control of your
Israeli finances

If you have multiple bank accounts or multiple credit cards in your household, things get complicated fast. You want to coordinate spending across all of them, set budgets, and understand how your bank accounts are going to look at a specific date after all pending credit card charges settle.

Nudlers gives you a single, unified view of all your accounts — even when you have several credit cards and bank accounts spread across the family. One dashboard, full visibility.

Nudlers uses the open-source israeli-bank-scrapers library. You provide your bank and credit card credentials, and the library logs into your accounts to fetch your transactions automatically. The scraping runs locally on your own machine — no third-party servers involved.

Nobody can see your data. Nudlers is a fully self-hosted, local-only application. Your financial data never leaves your machine. There are no cloud servers, no analytics, no external data transmission. It's your data on your hardware — period.

Your credentials are stored encrypted in the database using AES-256-GCM encryption. Nudlers uses a two-layer encryption model: a random master key encrypts your credentials, and that master key is itself encrypted by a key derived from your vault passphrase. Even if your database is compromised, credentials remain secure because the master key is never stored in plain form — only its encrypted version is.

The passphrase is never stored. Instead, it is used to derive a wrapping key (via scrypt, a memory-hard key derivation function) that encrypts the master key. The full chain looks like this:

Passphrase ──scrypt──▶ Wrapping Key
Wrapping Key ─AES-256-GCM─▶ Master Key (stored encrypted in DB)
Master Key ─AES-256-GCM─▶ Your credentials (stored encrypted in DB)

Once you unlock the vault, the master key is decrypted into server memory only — it is never written to disk. It is cleared automatically when the server restarts, requiring you to unlock again. If you forget your passphrase, the master key (and everything it protects) becomes permanently inaccessible.

No, the Gemini API key is optional. Gemini is used only for two features: chatting with AI about your own data in the app, and preparing the WhatsApp daily message. If you don't plan to use these features, you don't need an API key.

In the future, we will support other AI models. However, the recommended approach is to use Nudlers through MCP (Model Context Protocol), which allows AI tools like Claude to interact with your financial data directly.

Isracard has rate-limiting mechanisms that detect automated access. The scraper can fetch your transactions list, but to retrieve the category for each transaction, it needs to query them one by one. When you scrape a large date range, there are many transactions, and the category lookups can trigger rate limiting.

Tip: When you start seeing errors, minimize the date range you're scraping. Shorter periods mean fewer transactions and fewer category requests, which keeps you under the rate limit.

Nudlers also maintains a prefilled card that caches business-to-category mappings, so matching happens faster and reduces the number of requests needed over time.

Nudlers uses the whatsapp-web.js package. Under the hood, it runs a headless browser that connects to WhatsApp Web and utilizes your session to send messages. You scan a QR code once to link it, and then reports are delivered automatically.

It's just me, Eli Nudler. I built Nudlers to scratch my own itch managing finances across multiple Israeli bank accounts and credit cards. It's open source and free to use.
