What does Code Rivals do?

Code Rivals is a software development company that builds custom software, web applications, mobile apps (iOS and Android), AI chatbots, business automation and custom dashboards. We take products from idea and design through to launch and ongoing support.

Where is Code Rivals based?

We have two offices: one in Wolverhampton in the West Midlands, United Kingdom, and one in North Karachi, Pakistan. We work with clients across the UK, the USA, Europe, the Middle East and Pakistan.

Do you work with clients in the USA?

Yes. Many of our clients are US startups and businesses. Our UK and Pakistan teams overlap with US working hours, so you get a dedicated, affordable offshore development team with clear communication and regular updates.

Are you a software house in Karachi, Pakistan?

Yes. Our Karachi office in North Karachi is a full software house with developers, designers and project managers. Pakistani businesses can meet us locally, and international clients get the cost benefits of a Pakistan-based team.

How much does it cost to build an app or website?

It depends on scope. A focused MVP or business website can start from a few thousand pounds or dollars, while larger SaaS platforms and mobile apps cost more. Book a free 1:1 call and we will give you an honest estimate and a plan within days.

Can you add an AI chatbot or automation to my business?

Yes. We build AI chatbots trained on your own content, WhatsApp and website assistants, and automations that handle bookings, invoices, follow-ups and reports, using OpenAI, Make.com, Zapier, Airtable and custom Node.js.

Can you fix an app that keeps breaking in production?

Yes. We regularly take over unstable or vibe-coded projects, find what is breaking, stabilise the codebase, add monitoring and automated deployments, and then keep improving it so it stays reliable.

Which technologies do you use?

React, Next.js, Node.js and TypeScript for the web; React Native and Flutter for mobile; Supabase, Firebase, PostgreSQL and MongoDB for data; OpenAI for AI features; AWS and Docker for cloud; plus Stripe, Shopify, Auth0 and many third-party APIs.

We build digital products that scale.
