Quick answer: which is the best website development company in Kolkata?

Capital Numbers suits enterprises and funded startups that need a large engineering team. DreamzTech Solutions, Vrindra Digital and Complete Web Graphics have the strongest review profiles for mid-sized projects. Smaller agencies like Teqpro Solz suit small business sites. The right choice depends on budget, project size and the stack you need.

How we ranked these companies

• Review quality and track record: ratings and verified review counts on GoodFirms, Clutch and DesignRush, plus years in business and visible client work. Newer agencies with fewer reviews are placed on service fit and portfolio, so the order below is not a strict review-score ranking.
• Service depth: custom development, CMS, ecommerce, mobile and SEO capability.
• Pricing transparency: published hourly rate bands or clear starting prices.
• Location: Kolkata-based delivery teams. Several companies below also have overseas sales offices.

We did not run paid engagements with every company. Rankings reflect public data and may change. Check current reviews before you shortlist.

Disclosure: Vrindra Digital, entry #7, is our own company. We have applied the same criteria to it as to every other entry.
