Bonk

Bonk is a personal accounting tool for understanding the state of your finances. At its core, it is a declarative language for recording financial transactions based on the idea of double-entry bookkeeping. Using this data, you can define queries and dashboards/visualizations to help you answer questions about your finances.

Bonk has many features such as...

• A web-based frontend for visualizing data with customizable dashboards
• The ability to import transactions via Plaid
• An LLM-powered query generator
• A snapshot-testing tool for your transaction data
• A static checker to catch some mistakes in your transaction data
• An LSP implementation and VS Code extension for the Bonk language

For example, a ledger may contain transactions like...

2023-01-01 "Salary Deposit"
  assets/my_checking 1000.0
  income/acme_corp

2023-01-02 "Lunch"
  liabilities/my_credit_card -15.0
  expenses/food

2023-01-03 "Paying my credit card"
  assets/my_checking         -15.0
  liabilities/my_credit_card

The example ledger contains a full example that ultimately looks like this:

Bonk is heavily inspired by ledger, hledger, and especially beancount and its fava frontend.

Disclaimer

Bonk is no where near done, and may never be. I created it for my own personal use and open sourced it in case someone might learn from it. You probably shouldn't use it! (...but if you do, let me know!)
