Custom SaaS Development Company
Darwinbark is a software development company that builds custom SaaS products from architecture through to production launch. We work with startups who have a strong product idea and no in-house engineering team, and with growing businesses who need a dedicated technical partner to build, scale, and maintain a subscription product.
What We Build
Every SaaS engagement covers the full stack: system architecture and multi-tenancy design, a Laravel backend, a React or Vue frontend, subscription billing (Stripe, Razorpay, or PayPal), REST APIs and webhook integrations, admin and user dashboards, and cloud deployment on AWS or DigitalOcean - followed by ongoing post-launch support and scaling as the product grows.
How We Approach Multi-Tenancy
Most SaaS products need to serve many customers from one codebase without customer data leaking between accounts. We default to row-scoped tenancy (a tenant identifier enforced through a global query scope) for most B2B products, since it's cheaper to run and easier to evolve - and move to subdomain-per-tenant when a client needs stronger isolation or per-tenant custom domains from day one.
Subscription Billing, Handled Properly
Billing runs through webhook events rather than polling - a payment success, failure, or cancellation from Stripe or Razorpay reacts through the application immediately, gating feature access without the application having to guess at billing state on every request. That means fewer edge cases where a customer ends up in an inconsistent subscription state.
