Kakas
TypeScriptNext.jsRedis
Kakas replaces the spreadsheet I used to forecast my own cash flow. It keeps a dated ledger with a running balance after every line and flags the row where the balance bottoms out, so you can see the tightest moment coming rather than discovering it.
The amount field accepts Excel-style expressions such as -90*7 or -288-50-50, and a monthly panel summarises fixed costs and income by category. Built with Next.js and Kumo UI, with data in Upstash Redis behind a single-password gate.
