Key Differences Explained
Browser Extension Focus
Cupcake Development has built browser extensions as their core business for over 10 years, covering Chrome, Safari (including Swift-authorized App Store extensions), Firefox, and Edge. They completed a full Manifest V2 to V3 migration for CouponCabin, one of the largest U.S. coupon platforms, and shipped Safari Web Extensions for Monetha through Apple's notoriously strict review process. Safari Swift authorization is a rare capability that very few agencies can deliver.
Clover Dynamics lists browser extension development among several service lines, alongside AI integration, cloud solutions, and full-stack web apps. Their 50+ person team gives them breadth, but their public portfolio shows fewer named extension clients and less documented depth in cross-browser edge cases or platform migration work.
The practical difference shows up during development. Extension projects routinely hit platform-specific walls: Chrome Web Store policy rejections, Safari content blocker limitations, Firefox add-on review delays. An agency that encounters these problems daily solves them faster than one that hits them occasionally.
Cashback & Coupon Niche
Cupcake Development has built production cashback and coupon extensions for MyWorld (active across 10+ countries), CouponCabin (top-5 U.S. coupon site), Widilo (cashback leader in France and Spain), and Cashrewards (Australia's largest cashback platform). This means they understand affiliate network integrations (CJ, Rakuten, ShareASale), coupon injection mechanics, and the business logic behind cashback attribution at scale.
Clover Dynamics works across general e-commerce extensions without a documented focus on the cashback or coupon vertical. For a standard e-commerce extension, that generalist approach works fine. But cashback extensions carry specific complexity: real-time affiliate tracking, merchant offer matching, cross-domain cookie handling, and compliance with each affiliate network's terms of service. Getting any of these wrong costs the client real revenue.
Product Consulting
Cupcake Development positions itself as a product partner rather than a vendor. Their Clutch reviews repeatedly mention strategic input: clients describe them as "a smart partner suggesting the best solutions" rather than just executing specifications. In practice, this means they push back on feature requests that won't work in extension environments and suggest alternatives based on what they've seen succeed across 30+ production extensions.
Clover Dynamics operates primarily as a development service provider. Their team executes on client specifications with standard Agile methodology. This works well when the client has strong internal product leadership and just needs reliable development capacity. It's less ideal when the client needs guidance on extension architecture, Chrome Web Store optimization, or platform-specific UX decisions.
The distinction matters most for teams without deep in-house extension experience. If your product manager has never shipped a browser extension, having an agency that flags problems before they become costly is worth the difference.
The Numbers
Cupcake Development's client portfolio includes extensions that drive measurable business outcomes: Cashrewards attributes up to 50% of revenue to their browser extension, while EcoCart saw 33% organic shopper adoption after launch. Across their cashback clients, Cupcake Dev reports a 65% average increase in user engagement and 50% conversion growth. These results come from extensions running on millions of devices across Chrome, Safari, Firefox, and Edge.

How to Switch to Cupcake Development
Switching between two Eastern European agencies with similar tech stacks is usually straightforward. Here's how we handle the transition:
- Discovery call and codebase review. We look at your current extension architecture, browser coverage, and any pain points with the existing setup. Since both teams work with similar technologies, the assessment is usually fast.
- Technical audit of existing code. We evaluate Manifest version, content script structure, background service worker patterns, and affiliate integration points. If the codebase is well-structured, we can often continue building on it rather than rewriting from scratch.
- Transition plan with overlap period. We create a detailed migration timeline with clear handoff milestones. For live extensions with active users, we run a parallel period where both teams have access to ensure nothing falls through the cracks.
- Extension store continuity. Your Chrome Web Store, Firefox Add-ons, and Safari App Store listings stay live throughout. We handle the developer account transfers and review submissions so there's no gap in availability for your users.
- Post-switch SLA and monitoring. After the handoff, we provide SLA-backed maintenance covering bug fixes, browser updates (Chrome ships updates every 4 weeks), and store policy compliance.
