Ongoing care for add-ons, plugins and extensions

We keep your add-ons, plugins and extensions stable, fast and compatible with new platform releases. Our maintenance process ensures that each update of the CMS, core and third-party software won’t break your business logic or features.

Whether you use add-ons in CS-Cart, plugins in WordPress/WooCommerce, extensions in Magento or custom modules in proprietary systems — we handle ongoing adjustments, compatibility updates, code improvements and detailed release notes for every iteration.

We fix bottlenecks before they become issues: performance optimization, database health checks, caching strategy improvements and monitoring of API changes in integrated services. Security and compliance updates ensure that your plugins stay safe, even when core frameworks evolve.

Choose the level of service that fits your infrastructure and release frequency — from predictable scheduled updates to enterprise-grade SLA with proactive patching and continuous testing pipelines.

Multi-CMS expertise means smoother upgrades across stacks: CS-Cart, WordPress/WooCommerce, Magento, OpenCart, Bitrix and custom frameworks. We translate upstream changes into actionable tasks and keep your extensions future-proof.

Our CI/CD approach reduces risk: feature branches, code review, automated checks, regression suites and controlled rollouts with quick rollback paths. Emergency hotfix lane is available for critical incidents.

You get transparency at every step: a visible roadmap, estimates, risk register, weekly status reports and post-release monitoring to confirm stability and performance targets.

  • Compatibility with CMS core, templates, themes and other extensions
  • Systematic refactoring and modernization of add-on architecture
  • Release planning, regression testing and monitoring after deployment
