GetCostify.app VS Diffyn

GetCostify.app's answer

It's the only lightweight tool that handles both drinks (ml/l/oz) and dishes (g/kg) in one place, with yield/loss % built in and instant recalculation — most alternatives are either bare spreadsheets or heavy restaurant-management platforms with steep learning curves and enterprise pricing.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

GetCostify.app's answer

It's built specifically for the costing and pricing problem, not bundled into an inventory or POS suite you don't need. Cloud sync, unlimited recipes and export are available for €8.99/month — a fraction of the cost of heavier tools like MarketMan or MarginEdge, without sacrificing accuracy.

Diffyn's answer:

Diffyn is the platform that specializes on both change management and multi-model analysis.

GetCostify.app's answer

Alpine.js on the frontend, Supabase (Postgres) for auth and data, Stripe for subscription billing — a single-page web app.

GetCostify.app's answer

Owners and managers of small independent cafés, coffee bars, cocktail bars and kitchens who currently price their menu by feel or in ad-hoc spreadsheets, and want an accurate, fast way to know their real margins.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

GetCostify.app's answer

Built after watching café and bar owners repeatedly under-price drinks and dishes because manual spreadsheet costing was too slow to keep up with changing ingredient prices — GetCostify turns that into a 30-second calculation instead of a recurring spreadsheet chore.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
