Why is it free?

AllerEasy was built from direct experience managing allergen data across UK hospitality venues — wrestling with printed folders, scattered spreadsheets, and the constant pressure of keeping information accurate for guests with allergies. It became clear the industry needed a better tool, not another paid subscription. So the entire codebase is open-sourced under the GPL v3 licence. Any catering business — a single café or a multi-site group — can download it, deploy it, and use it without paying a penny.

How AllerEasy works

From your existing allergen data to a live, branded guest menu — in three steps.

1
Deploy the app

Clone the code from GitHub and deploy to Heroku, Railway, Render, or any server that supports Python. The README walks through every step — no developer experience needed.

2
Upload your menu data

Import dishes from a CSV or JSON file — the format your existing allergen spreadsheet likely already uses. Set allergens, kcals, nutrition, categories, and dietary flags per dish.

3
Share with guests

Guests browse your branded menu on any device, filter by allergen, and see kcals and nutrition at a glance. Staff still take orders — AllerEasy is an information layer, not an ordering system.

Everything a catering business needs

AllerEasy covers the full allergen and nutrition management workflow, out of the box.

All 14 regulated allergens

Track every EU/UK regulated allergen per dish. The allergen converter automatically groups common variants — wheat, barley, rye, and oats all map correctly to "Cereals containing gluten".

Full nutritional data

Store and display calories, carbs, protein, fat, saturated fat, sugar, fibre, and salt per dish — supporting UK calorie labelling requirements for larger operators.

Bulk import — CSV & JSON

Upload your entire menu in one go from a spreadsheet or data export. No manual entry needed if you already have allergen data in a structured format.

Full branding control

Set your logo, colour palette, fonts, and imagery per menu type. The customer-facing menu looks like your brand — not a generic compliance tool.

Audit trail & change logging

Every edit to a dish is recorded — who changed it, when, and why. A clear compliance record for teams and venues where accountability matters.

Multi-user staff access

Create accounts for chefs, managers, and F&B teams with appropriate permissions. Superusers manage branding and users; standard accounts manage dish data.

Who AllerEasy is for

Any food-led business that needs to manage allergen and nutrition information for guests — from a single café to a national group.

Restaurants & cafés

Let guests check allergens and kcals at the table via QR code, without interrupting your service. Keep printed folders as a backup, not the primary reference.

Parks, resorts & multi-site venues

Manage allergen information across multiple venues and seasonal menus from one dashboard. Branding can be customised per site while sharing the same dish database.

Schools, hospitals & contract catering

Where allergen accuracy is critical and menus change regularly, the audit trail provides a reliable compliance record. The app is free to deploy in any institutional setting.

Food trucks & market traders

A lightweight, self-hosted app is ideal for smaller operators who want professional allergen information without enterprise software costs.

Developers & digital teams

Built on Django with a clean, documented structure. Fork it, extend it, integrate it with your EPOS or reporting tools. The code is yours to adapt under the GPL v3 licence.

Hospitality groups & franchises

Deploy once and brand independently for each venue or brand within your group. Consistent compliance, flexible presentation, zero ongoing licensing cost.
