AGPL ERP for shops that outgrew spreadsheets but reject SaaS lock-in.
Quick DCF wraps a compact DCF engine into a browser toolbar: type a ticker, tweak growth/WACC/terminal via sliders, and get an intrinsic-value vs current-price readout plus a 10-year FCF projection. It’s privacy-friendly (calculations local, no account) and small in size, but the idea isn’t novel — the win here is convenience and speed rather than a new valuation method. Watch the Yahoo Finance data dependency and the simplifications in the DCF assumptions if you plan to use it for real investing.
Useful math, but a spreadsheet does this same calculation for free.
SQLite ERP that runs locally, no cloud sync, no forced accounts—genuine anti-SaaS positioning.
Automates 90% of document intake for forensic accounting cases.
Nice, focused feature set — salary slider, Scotland tax bands, student loan options, pension relief and employer-cost math are all surfaced without burying the user in jargon. It doesn't invent a new category, but the tax-band visualization and advanced options (tax codes, employer NI) show care; I'd want export/print and privacy/version notes before recommending it widely.
