Web App Development — custom SaaS portals, dashboards and internal web applications

Web App Development is a service in which Gamostar builds multi-tenant SaaS products, customer and partner portals, booking systems, admin dashboards and internal tools as web applications. It is aimed at companies that need a custom browser-based application delivered by an external development team.

Delivery model, stack and engagement options

Gamostar offers three engagement models: a fixed-price project with a defined scope, timeline and price, which suits MVPs and well-documented requirements; a dedicated team of developers, designers and QA working only on the client’s product on a monthly basis; and time and material billing at an hourly rate for evolving scope, audits and ongoing improvements. Engineers work with React / Next.js, Node.js or Laravel, PostgreSQL or MongoDB, and AWS, GCP or Azure cloud infrastructure.

Functional scope

Deliverables include role-based portals and dashboards with reports, exports and notifications, plus subscriptions, billing and usage analytics for SaaS products. REST and GraphQL APIs connect the application to CRM, ERP and payment systems. Security measures include OWASP practices, encryption, SSO, role-based access and audit trails.

Delivery process and handover

Development uses weekly demos, short sprints, real-device testing, and performance, load and security checks before each release. Gamostar signs an NDA before work starts and hands over full source code, design files and documentation. Post-launch support covers bug fixing, OS-update compatibility, monitoring and feature upgrades under flexible plans.

Track record

Gamostar states that it has delivered more than 250 games, apps and platforms for startups and enterprises.

Companies replacing legacy systems can have them rebuilt as maintainable web apps, with Gamostar handing over full source code and documentation at the end of the project.
