Direct answers on services, costs, timelines, tech stacks, modernization, AI, security, IP, and geos.
A web application development company designs, builds, deploys, and maintains custom web applications. That includes SaaS platforms, portals, dashboards, marketplaces, and AI powered web apps. The engagement covers product design, architecture, full-stack development, DevOps, QA, security, and post launch support under one team.
A focused MVP web app starts around $20,000. A full SaaS platform with multi tenant architecture, billing, SSO, and analytics typically runs $80,000 to $300,000. Enterprise web apps with deep integrations and compliance can exceed $500,000. Hourly engagements from $25 per hour, dedicated developers from $3,500 per month, dedicated pods from $9,000 per month. We share a written fixed-price estimate after a free 30 minute discovery call.
An MVP web app usually goes live in 8 to 14 weeks. A full production SaaS with billing, SSO, and observability runs 4 to 6 months. Enterprise web apps with deep integrations and compliance add another 3 to 6 months. We share a sprint by sprint plan after architecture.
React, Next.js, Vue, and Angular on the frontend. Node.js, Java Spring, Python, Go, and .NET on the backend. PostgreSQL, MySQL, MongoDB, and Redis for data. AWS, Azure, and GCP for cloud. We pick the stack that fits your team, scale needs, and existing investments.
