AppForge

AppForge Solution is a Budapest-based engineering team building custom web, mobile, e-commerce and AI products for SMB and midmarket clients across Hungary, Austria, Germany and the wider EU.

Our stack: Astro, Next.js, React, React Native, Flutter, Node.js, Go, TypeScript, Python - and only senior engineers touch the code.

What we deliver

Web Development: Astro / Next.js sites and apps that hit 95+ Core Web Vitals, multi-language, headless CMS (Sanity, Strapi, Storyblok).

E-commerce: WooCommerce, Shopify and headless commerce with EU payment gateways (Stripe, Mollie, Adyen, Klarna, SimplePay, Barion) and NAV-compliant invoicing.

Mobile Apps: cross-platform (React Native, Flutter) and native (Swift, Kotlin) iOS / Android, including App Store and Play deployment and ASO.

AI Integration: RAG chatbots resolving 40-70% of support tickets in HU/EN/DE, internal company GPT deployments, document processing pipelines, AI agents, on-premise LLM infrastructure aligned with GDPR and the EU AI Act.

Recent work: a Hungarian pop-culture heritage AI search engine (presented at AI Summit Budapest 2025), a B2B construction-materials Q&A database from 100+ GB of supplier PDFs, and several production customer-support chatbots.

How we work: discovery -> Figma designs -> 2-week sprints with a working demo every Friday -> automated and manual QA -> release with monitoring -> optional monthly retainer.

Why teams pick us

Every engineer is in-house, in CET. No subcontracting, no overnight handoffs.

EU-compliant: Hungarian Kft, GDPR-aligned, EU-VAT invoicing, DPA on request.

Prototype-first - we usually have something clickable in week one, not month two.

Modern stack only - no legacy WordPress themes, no jQuery.
