Actual Budget
Local-first envelope budgeting with an official Node API package and CLI.
Free · PikaPods managed hosting (third party): $2 per month
- I want a budget my agent can post transactions into and read balances from, with the file on my own machine
- I am moving off YNAB and want an app I can script
- Custom reports and dashboards
- Personal budgeting; no invoicing, clients or tax reporting
- The API opens the budget file directly and should not run against the same file the desktop app has open in some setups; read the API docs on sync
- A finished product: the Customization surface is deployment only
Fungible
Keyboard-first personal finance TUI with Plaid sync and a built-in MCP server and HTTP API.
Free
- I live in the terminal and want Claude to tidy my transactions and answer 'how much did I spend on travel'
- I want a local finance dataset my agent can query without a cloud budgeting service
- Import CSV statements
- Dedup review of CSV vs Plaid
1 more job is undetermined.
- The desktop GUI does not start the MCP or API servers; use stdio MCP with the GUI
- Installers are un-notarized: Gatekeeper and SmartScreen warnings on first launch
- Deleting ~/.fungible/key means re-linking every bank
Ray Finance
Local-first AI financial advisor CLI over Plaid or Bridge bank data, bring your own model.
Bring your own keys · Pro (managed keys): $10 per month
- I want a money advisor that knows my situation and runs on my laptop with a model I choose
