FairyLoot, a leading subscription box retailer, faced slow checkouts, unstable queues, and manual renewals that were limiting growth. Following a website audit, Syde optimized FairyLoot’s custom eCommerce platform, delivering fast checkouts, automated subscriptions, and a scalable system ready to support future growth.
The challenge:
Navigating Growth and Performance Hurdles
FairyLoot, a well-established company beloved by book lovers, has a strong online presence with e-commerce shops serving a global market. Known for its curated book subscription boxes and vibrant community, FairyLoot connects readers worldwide with exclusive releases and themed merchandise.
Following the relaunch of a custom theme, FairyLoot faced slow checkout times, an unstable queue, and the manual management of many subscription renewals each month due to auto-renewal failures. System limitations were also constraining subscription growth. These issues were creating friction for customers and limiting growth, prompting the need for a development partner to stabilize, optimize, and scale their website.

The solution:
A Strategic Audit and Targeted Improvements

Laying the Foundation Through a Website Audit
As a starting point, Syde recommended a comprehensive audit of FairyLoot’s website to ensure both immediate and long-term needs were addressed. The audit focused on three key areas: performance, security, and maintainability.
It revealed opportunities to speed up the site by optimizing images, scripts, and database performance, removing redundant data, and streamlining subscription management. Security and compliance were maintained as a top priority to safeguard customer data. On the maintainability side, cleaning up outdated code, fixing errors, and enforcing best practices ensured the system would be easier to manage and more reliable.
The audit provided a clear roadmap, showing that targeted optimization, rather than a full relaunch, could enhance performance, security, and scalability. This approach saved FairyLoot time and money while improving the customer experience and supporting future growth.
Turning Insights Into Action
After the audit, we moved into implementation, translating insights into tangible results. We began with a prioritized action plan, targeting the most critical areas affecting performance, stability, and security.
Database cleanups, query optimizations, front-end performance enhancements, and robust coding standards were implemented efficiently with minimal disruption.
Continuous monitoring using tools allowed us to validate changes in real time, quickly address any issues, and benchmark performance before and after each major update.
Security was strengthened through proactive updates, thorough code reviews, and the removal of unused or vulnerable third-party components.
To ensure long-term maintainability, we embedded practices such as visual regression testing and strict coding standards, reducing technical debt and making future updates easier. These actions not only resolved immediate challenges but also set up FairyLoot’s system for lasting stability, faster performance, and scalable growth.

The Outcome:
A Faster, Stronger eCommerce Site Ready for Growth
Even under heavy traffic, customers now enjoy smooth, seamless checkouts, while fully automated subscription renewals eliminate major obstacles and support significant growth in the subscription base.
We continue to support FairyLoot through ongoing maintenance and agile development, keeping the system reliable while delivering new features and improvements as needed. With their core platform running smoothly, they can focus on ambitious projects to expand their online presence, demonstrating how proactive support and system optimization free businesses to innovate and grow.
Key results:
From Bottlenecks to Smooth Operations

- Database Cleanup: Approximately 10 million redundant rows removed, including 2.7 million duplicates from a previous migration.
- System Reliability: Flash-sale demand spikes are now absorbed without the performance degradation that would typically push traditional platforms beyond their operational limits.
- Automated Renewals: Removes the need for manual intervention, saving time and enabling scalability
