Web Software Istanbul: A 2026 Guide for Enterprise Web and SaaS
Makrops Engineering Team
Software, 3D and AI engineering · Istanbul / Berlin / New York
"Web software Istanbul" is a buyer-intent search: enterprises and product owners building web applications, B2B portals, or SaaS — not static corporate sites. This guide covers vendor selection, modern stack, pricing, and timelines in Istanbul for 2026.
1. "Web software" vs. "web design"
A clear separation:
- Web design: corporate sites, blogs, landing pages, static content. WordPress, Webflow are enough.
- Web software: user accounts, data persistence, workflows, reporting, integrations. Custom code (Next.js, Django, .NET, Node) required.
2. Project types in Istanbul
a) Internal admin / tool
- Users: 10-200 internal
- Duration: 3-6 months
- Budget: $20-130K
- Stack: Next.js + Node/Python, Postgres, internal auth
b) B2B customer portal
- Users: 100-5,000 external
- Duration: 4-9 months
- Budget: $45-250K
- Stack: Next.js + Node/Go, Postgres, ERP integration (SAP/Logo/Mikro)
c) SaaS product (B2B)
- Users: 100-50,000 paying
- Duration: 6-18 months
- Budget: $75K-$800K
- Stack: Next.js + Node/Go + Postgres + Redis + AWS/Vercel + Stripe/Iyzico
d) Marketplace
- Users: 1,000-100,000+
- Duration: 9-18 months
- Budget: $120K-$1M
- Stack: Next.js + Node + Postgres + Elastic + Stripe Connect
e) Reporting / BI dashboards
- Users: 5-50 managers
- Duration: 2-4 months
- Budget: $15-65K
- Stack: Next.js + ClickHouse/BigQuery + Metabase/Superset hybrid
3. Modern stack (2026)
The standardized stack across strong Istanbul web software firms in 2026:
Frontend: Next.js 15 (App Router), React 19, Server Components, Tailwind, shadcn/ui, TanStack Query, Zustand, TypeScript. Backend: Node.js (NestJS / Hono / Fastify) or Go, Postgres 16+, Redis, Drizzle/Prisma, tRPC or OpenAPI + Zod. Infra: Vercel or AWS (ECS / Lambda), GitHub Actions CI/CD, Sentry, PostHog / Amplitude, Cloudflare. Auth: Auth.js, Clerk, or Keycloak (enterprise).PHP + MySQL + jQuery still runs legacy projects but is no longer recommended for new builds.
4. Timelines: a typical 6-month project
| Month | Phase | Output |
| --- | --- | --- |
| 1 | Discovery + UX | User scenarios, wireframes, architecture decisions |
| 2 | Design + sprint 0 | UI kit, prototype, repo + CI |
| 3-4 | Sprints 1-4 | Core modules, first demo |
| 5 | Integration + tests | ERP/CRM hookup, e2e tests |
| 6 | UAT + go-live | Pilot users, training, launch |
5. Pricing in 2026
Istanbul web software projects price hourly. Typical bands:
| Role | Hourly (€) |
| --- | --- |
| Junior dev | 18-25 |
| Mid dev | 28-40 |
| Senior dev | 40-60 |
| Tech lead | 55-80 |
| UX designer | 30-50 |
| Product manager | 40-65 |
6. Selecting an Istanbul firm
Profile types
1. Enterprise integrators (Levent / Maslak): big-client, heavy process, high price 2. Product studios (Kadıköy / Beşiktaş): fast, modern stack, mid price 3. SME shops (Beylikdüzü): templates, low price, limited customization 4. Freelance teams: volatile, risky, cheap
Categories 1 and 2 are appropriate for real web software.
8 vendor questions
1. How many web software projects of this scale have you delivered? 2. Who is the tech lead, with how many years of experience? 3. Are source-code rights clearly defined? 4. What is your test strategy (unit, integration, e2e)? 5. How does your CI/CD work? 6. How is production monitoring set up? 7. Do you commit to a performance budget (LCP, INP, TTFB)? 8. Do you have a KVKK / GDPR co-controller agreement?
7. Seven common mistakes
1. Wrong stack — legacy PHP/jQuery rebuilds in 3 years 2. Starting from design — architecture comes first 3. Microservices in a small team — infra hell 4. Deferring tests — 10× cost later 5. No performance budget — 5s+ load kills conversion 6. Custom auth — invitation to vulnerabilities 7. Old-school admin — modern admin (TanStack Table + shadcn) is 3-4× faster to operate
8. SEO + web software overlap
Even non-content web software projects need SEO awareness:
- B2B portals usually have a landing surface
- SaaS combines marketing site + app (same Next.js codebase)
- Marketplaces generate millions of SEO pages via product/category templates
9. Where Makrops fits
Makrops is a B2B web software studio in the Kadıköy belt. Typical clients:
- Enterprise admin panels with ERP/CRM hookups
- B2B portals with 200-3,000 external users + ERP integration
- Custom SaaS, 6-18 months from design to live
- 3D + web hybrid products (ecommerce + WebGL configurators)
10. Closing
In 2026, web software in Istanbul is its own discipline: modern stack, product thinking, performance budgets, and KVKK compliance are now standard.
Right vendor = niche + scale + stack alignment. RFP + pilot does the rest.
