Web application development for SaaS products, dashboards and internal tools
If you want to turn a spreadsheet-driven process into real software, get a SaaS idea in front of its first paying customers, or give your team a dashboard they actually enjoy using, you are in the right place. Weras Labs is a software company that builds and sells its own products. The same team, with the same standards, designs, builds and runs custom web applications for clients: fast, secure, and available from any browser without installation.

What kind of web applications we build
A web application is different from a marketing website: people sign in, enter data and get work done in it. The projects we build most often:
- SaaS products: subscription software with multi-tenant data, so every customer's records stay separate.
- Admin dashboards: internal screens for orders, customers, staff, content or field teams.
- Customer portals: a private area where your clients track orders, invoices or documents.
- Browser-based business software: replacing ageing desktop programs with an app that runs on a server and works from anywhere.
- MVPs: a focused, solid first version to validate an idea with real users before raising money or scaling up.
We use the same foundation in our own products: authentication, roles and permissions, payments, email notifications and an admin area. That means we don't reinvent the basics on every project; we build your business logic on a proven skeleton.
What a typical web app includes
Every project is different, but most web applications share the same building blocks. During scoping we go through them together and keep only what you really need:
- Sign-in with email, Google or one-time codes
- Roles and permissions for admins, staff and customers
- Lists with filters, search and CSV/Excel export
- Overview dashboards with charts and reports
- Card payments and subscription management
- Email, SMS or WhatsApp notifications
- API integrations with accounting, shipping, marketplaces or your existing systems
- AI-assisted features such as document summaries or automatic categorisation
Shipping a few valuable features properly beats shipping everything halfway. We help you prioritise and plan the rest for later releases.
What drives cost and timeline
There is no fixed price for a web app; cost follows scope. The biggest factors are the number of screens and workflows, how complex user roles are, third-party integrations, payments and subscriptions, multi-language support and how sensitive the data is.
As a rough guide, a simple admin dashboard or MVP usually takes 4–8 weeks, and a mid-sized SaaS product with integrations and billing takes 8–16 weeks. Larger projects are split into phases, each ending with a usable release.
Describe your project in a few sentences and we will send a free quote with a clear scope, timeline and cost. If budget is tight, we can trim or phase the scope to fit.
Our technology stack
We use mainstream, modern technology that stays maintainable for years:
- Frontend: Next.js, React and TypeScript for fast, responsive interfaces
- Backend: Node.js APIs, scheduled jobs and background workers
- Data and auth: Firebase (Firestore, Authentication) or PostgreSQL when the data model calls for it
- Hosting: Vercel or Google Cloud with automated deploys, backups and monitoring
- AI: Claude and Gemini APIs where they genuinely add value
You own the full source code and it runs in your own accounts. If you ever move to another team, the project is readable and documented.
Why work with Weras Labs
We are a small senior team led by our founder, Habip Dayan. Instead of going through an account manager, you talk directly to the developer writing your code, which makes things faster and avoids misunderstandings. Because we run our own products in production, we know security, performance and maintenance from real use, not from slides. We are based in Turkey and work remotely with clients across Europe, the US and beyond, with regular preview links so you always see progress.

Frequently asked questions
How long does it take to build a web application?
A simple admin dashboard or MVP usually takes 4–8 weeks. Projects with billing, integrations and multiple user roles can take 8–16 weeks. We confirm the exact timeline in writing once the scope is clear.
How much does custom web app development cost?
Cost depends on the number of screens, user roles, integrations and payment requirements. Instead of a one-size package we prepare a free quote for your project. If budget is limited, we can start with a smaller first phase.
Can you build our SaaS product from scratch?
Yes. We build SaaS products end to end, including subscriptions, multi-tenant data, an admin dashboard and payments. We build and sell our own software the same way, so we understand both the technical and the commercial side.
Can you replace our old desktop software with a web app?
Yes. We review your current screens and data, rebuild the workflow as a browser-based app that works on any device, and plan the data migration as part of the project.
Who owns the code and the data?
You do. The application runs in your own accounts and we hand over all access and the full source code at delivery.
Do you work with clients outside Turkey?
Yes. We work remotely with clients abroad in English, with regular calls and preview links. Time zones in Europe and the Middle East overlap well with ours, and we adjust for US clients.
