Frequently Asked Questions

The questions every founder asks us.

  1. We specialize in a full range of open source solutions, including custom web applications, CMS development (WordPress, Drupal, Joomla), e-commerce platforms (Magento, WooCommerce), frameworks (Laravel, Symfony, CodeIgniter), frontend libraries (React.js, Vue.js, Angular), and backend technologies (Node.js, Python with Django/Flask). These are tailored for startups, enterprises, and digital agencies needing flexible, community-driven tools.

    • Discovery & Planning: Understanding business goals, selecting the right open source stack, and creating a roadmap
    • Design & Customization: UI/UX design, theme/plugin customization, and architecture setup
    • Development & Integration: Core coding, module extensions, third-party integrations, and iterative Agile sprints
    • Testing & Deployment: Rigorous QA, security audits, performance optimization, and seamless launch with CI/CD

  3. We leverage proven, community-backed technologies for robust results:

    • CMS: WordPress, Drupal, Joomla
    • E-commerce: Magento, OpenCart, WooCommerce
    • Frameworks: PHP (Laravel, Symfony, Yii), Python (Django, Flask), Node.js
    • Frontend: React.js, Angular, Vue.js
    • Databases: MySQL, PostgreSQL, MongoDB. Deployed on cloud platforms like AWS, Azure, or DigitalOcean for maximum flexibility.
    • Regular updates and patching of core, themes, and plugins
    • Implementation of secure coding standards and input validation
    • Vulnerability scanning and penetration testing (VAPT)
    • Hardening measures like firewalls, SSL/TLS, role-based access control, and compliance with OWASP guidelines
    • Ongoing monitoring and security audits to address community-reported issues promptly

  5. Timelines depend on project scope. A standard WordPress or Laravel-based website can be delivered in 4–8 weeks, while complex Magento e-commerce platforms or Drupal enterprise portals may take 3–6 months. We provide accurate estimates after the discovery phase, with Agile sprints ensuring faster milestones.

  6. Key variables include project complexity (custom modules vs. off-the-shelf), number of integrations, design customization, performance requirements, and engagement model. Open source drastically reduces licensing costs compared to proprietary software-costs are driven by development hours, with Fixed Price options for defined scopes or Time & Material for evolving needs.

  7. We offer comprehensive SLAs, including core/plugin updates, security patches, performance tuning, backup management, and 24/7 monitoring. Support starts with a 3–6 month warranty period covering bug fixes at no extra cost, followed by flexible retainers for ongoing enhancements, version upgrades, and emergency response.

    • Architecture designed for horizontal/vertical scaling from the start
    • Use of caching (Redis, Varnish), CDN integration, and load balancing
    • Cloud-native deployment with auto-scaling groups
    • Modular code and microservices were needed.. This allows seamless handling of traffic growth from thousands to millions of users.

  9. Yes, 100%. While we build on open source licenses (GPL, MIT, etc.), all custom code, themes, plugins, and configurations developed specifically for you are fully owned by the client. This is protected under our Master Services Agreement (MSA) and NDA signed at project onset.
