10+ years building web applications
We've been doing this since 2014. That's enough time to see what actually works in production, which shortcuts lead to technical debt, and how to build apps that are still running smoothly years after launch.
We build custom web applications that solve real problems. A USA-based React and Next.js team since 2017. From MVPs to enterprise platforms, we've helped companies launch products used by millions.

Full web app deployedHere's what we help businesses overcome.
Your current website is slow, outdated, and hurting conversions
Performance-optimized apps with modern frameworks. Fast load times, better rankings.
You've been burned by agencies that disappeared after launch
Ongoing support, security monitoring, and iterative improvements included.
You don't have the in-house resources to build what you need
Senior developers and architects who integrate with your workflow.
Security vulnerabilities and data breaches keep you up at night
Secure coding from day one. OWASP compliance, encryption, proper authentication.
Your systems don't talk to each other, creating manual work
API development connecting CRMs, payment processors, ERPs, and legacy systems.
You need to launch quickly but can't sacrifice quality
Bi-weekly sprints with tested, production-ready releases.
We've been building web applications since 2014. That experience shows in faster delivery, fewer bugs, and applications that actually work in production.
Ship faster without cutting corners
We've been building web apps since 2014. That experience translates to fewer surprises, better estimates, and code that doesn't need to be rewritten six months later. You get speed from knowing what works, not from skipping steps.
Technology that ages well
React, Next.js, Node.js, PostgreSQL. We stick to technologies that have proven themselves in production at scale. Your app won't be stuck on a framework that's abandoned next year. It'll be built on a stack with strong community support and a clear future.
Full-cycle ownership
From first conversation to ongoing support, we handle the entire lifecycle. Design, development, testing, deployment, maintenance. You don't need to coordinate between multiple vendors or worry about handoffs. One team, accountable for everything.
Built to scale when you need it
The architecture handles growth. Whether that's 100 users or 100,000. We've built apps that went from MVP to millions of users without requiring complete rewrites. Scaling is planned from the start, not bolted on as an afterthought.
Full-cycle development from planning through launch and beyond. We handle everything so you can focus on your business.
We build web applications from scratch, tailored to how your business actually works. Not templates, not generic solutions. Every feature, workflow, and integration is designed around your specific requirements. Whether you're replacing spreadsheets with something that scales or building a product that'll serve millions of users, the architecture is built for your use case.
React is our bread and butter. We've been working with it since 2017 and have built everything from simple dashboards to complex SaaS platforms. Next.js gives us server-side rendering, static generation, and API routes out of the box, which means faster load times and better SEO without the usual trade-offs.
SaaS applications need multi-tenancy, subscription billing, usage tracking, and the kind of reliability that keeps paying customers happy. We've helped startups launch MVPs that attracted investment and helped established companies modernize their legacy products. The tech stack is chosen to minimize hosting costs while maximizing performance.
Your web app needs to talk to other systems. CRMs, payment gateways, ERPs, third-party services. We design and build APIs that are well-documented, secure, and actually pleasant to work with. RESTful endpoints, GraphQL when it makes sense, webhook integrations for real-time updates.
Good design isn't about making things pretty. It's about making sure users can actually accomplish what they came to do. We create wireframes and interactive prototypes before writing a single line of code, so you can test ideas with real users and catch problems early, when they're cheap to fix.
PWAs bridge the gap between web and mobile. They work offline, send push notifications, and feel like native apps without the app store hassle. We build progressive web apps that load fast on slow connections, install on home screens, and update automatically. Good fit when you need mobile reach without maintaining separate iOS and Android codebases.
Customer portals, partner portals, self-service platforms. We build web portals that give users access to what they need without drowning your support team in requests. User management, dashboards, document sharing, workflow automation, all connected to your existing systems through secure APIs.
Slow web apps lose users. We optimize everything that affects load time: image compression, code splitting, lazy loading, CDN configuration, database queries. Core Web Vitals aren't just metrics to us. They're the difference between users who stay and users who bounce.
Launching is just the beginning. Dependencies need updates, security patches need applying, and bugs need fixing. We provide ongoing support that keeps your web app running smoothly, with monitoring, regular updates, and quick response times when something goes wrong.
Enterprise projects come with their own set of challenges: SSO integration, role-based access, audit logs, compliance requirements. We've built internal tools for companies with 500+ employees, where downtime costs real money. The architecture handles complex workflows, integrates with existing systems, and scales as the organization grows.
Real projects, real results. Here are some of the web applications we've developed for our clients.

Trading Platform for Gamers
A trading and community platform for Rocket League players. 5M+ monthly active users, real-time trading, user-generated content, and the kind of scale that tests every assumption about performance.

Commercial Mortgage Marketplace
Online commercial mortgage marketplace connecting borrowers to a vast network of lenders. React/Redux dashboard with reusable components and universal data handling. Later acquired by Iuvity.

AI-Powered Skincare Platform
Personalized skincare recommendations powered by AI. Users upload photos, get skin analysis, and receive product suggestions. Web app handles complex image processing and ML inference at scale.
Share your idea. We'll give you a realistic timeline, ballpark estimate, and honest feedback.
These are the apps your customers interact with directly. eCommerce platforms, booking systems, self-service portals. They need to be fast, intuitive, and reliable. We build customer-facing apps that handle traffic spikes, work across devices, and turn visitors into paying users. The UX is designed around real user behavior, not assumptions.
See example:Rocket League Garage5M+ users→Most companies run on a mix of spreadsheets, emails, and workarounds. Internal apps replace that chaos with actual systems. Inventory management, project tracking, approval workflows, reporting dashboards. We build tools that employees actually want to use, which is harder than it sounds.
See example:AI Support Agent→SaaS products have their own rhythm. Multi-tenant architecture, subscription management, usage analytics, onboarding flows. We've helped founders go from idea to paying customers, and helped established products add features without breaking what already works. The goal is always sustainable growth, not just a successful launch.
See example:Finsu$500K raised, 50K+ users→Portals aggregate information and functionality in one place. Customer portals, vendor portals, partner dashboards. Users log in, see what matters to them, take action. We build portals that integrate with your existing systems, display real-time data, and reduce the back-and-forth that eats up your team's time.
See example:Breeze2-5x cost reduction→Sometimes off-the-shelf CMS solutions don't cut it. We build custom content management systems when your publishing workflow is complex enough to justify it. Editorial workflows, content scheduling, multi-site management, API-first architecture for headless setups.
See example:Rocket League Garage10M+ items listed→Applications that make sense of data. Analytics dashboards, reporting tools, visualization platforms. We build web apps that connect to your data sources, process large datasets, and present insights in ways that actually help people make decisions. Not just charts, but actionable information.
See example:Healify$2M raised, AI-powered insights→Modern, proven technologies chosen for performance, maintainability, and long-term support. No experimental frameworks that might be abandoned next year.


We dig into what you're actually trying to accomplish. Not just features, but business goals, user needs, and constraints. The result is a clear scope, realistic timeline, and a plan that everyone agrees on before writing any code.
We create wireframes and interactive prototypes that you can click through and test. This catches UX problems early, when fixing them costs hours instead of weeks. The final designs are polished, responsive, and ready for development.
The building phase. We work in 2-week sprints with regular demos so you see progress and can give feedback. Front-end, back-end, APIs, integrations. Everything is built incrementally, tested continuously, and documented as we go.
Before launch, we test everything. Unit tests, integration tests, browser compatibility, mobile responsiveness, performance benchmarks, security checks. We find the bugs before your users do.
We set up the production environment, configure monitoring, run final checks, and deploy. Launch day is planned, not chaotic. We're available to handle any issues that come up in the first days of operation.
We've built web applications across a range of industries. Each comes with its own requirements, and we bring that domain knowledge to every project.
Banking apps, payment platforms, investment tools. We understand the compliance requirements, security standards, and user expectations that come with handling money. The web apps we build in this space process transactions reliably and keep sensitive data protected.
See example:Finsu$500K raised, 50K+ users→Patient portals, telemedicine platforms, health tracking apps. Healthcare projects come with HIPAA considerations and users who need things to just work. We've built apps that handle appointment scheduling, health data integration, and secure messaging.
See example:Healify$2M raised, AI health companion→Online stores, inventory systems, order management. eCommerce demands fast load times, reliable checkout, and the kind of performance that keeps customers from abandoning carts. We build platforms that handle seasonal traffic spikes and integrate with payment and shipping providers.
See example:BeautyAdvisor7x performance, 40% savings→Property listing platforms, tenant portals, management systems. Real estate apps deal with search, maps, scheduling, and document management. We build solutions that help agents, property managers, and buyers find what they need faster.
See example:BreezeTenant-landlord matching platform→Tracking systems, warehouse management, delivery optimization. Logistics apps need real-time data, integrations with hardware, and interfaces that work in fast-paced environments. We build tools that give operations teams visibility and control.
See example:EvLuv65K+ stations on the map→Community platforms, content delivery, user engagement. We built Rocket League Garage, a gaming platform with 5M+ users. Experience with high-traffic, highly interactive applications where performance and user experience are everything.
See example:Rocket League Garage5M+ users→Booking systems, training platforms, community apps. Sports and fitness apps need to handle scheduling, progress tracking, and social features. We build platforms that keep users engaged and coming back.
See example:FunPadel1000+ players, 6 countries→MVPs, product launches, rapid iteration. Startups need to move fast without accumulating technical debt that slows them down later. We've helped companies go from idea to funded product, and from funded product to market leader.
See example:HealifyIdea to $2M funding in 6 months→Honest pricing based on real projects. These ranges reflect what custom web app development actually costs when done properly.

$80,000 – $120,000
12-16 weeks
Complex applications with advanced features, multiple user roles, third-party integrations, and enterprise-grade security.
Best for: Large organizations, regulated industries
Simple CRUD operations cost less than complex workflows with conditional logic, state machines, and real-time updates. The more business rules encoded in the application, the more development time required.
Each integration adds complexity. A single payment gateway is straightforward. Multiple ERPs, legacy systems, and custom APIs take more time. Poorly documented third-party systems are especially time-consuming.
Custom design with unique UI patterns costs more than working from established design systems. Animation, complex data visualizations, and polished micro-interactions add to design and development time.
Healthcare, finance, and government projects require additional security measures, audit logging, and compliance documentation. HIPAA, SOC 2, or GDPR requirements typically add 15-25% to the total cost.
Applications expected to handle high traffic from day one need more robust infrastructure, caching strategies, and load testing. Starting small and scaling later is often more cost-effective.
Aggressive timelines sometimes require additional team members or parallel workstreams. This can speed delivery but increases coordination overhead. Realistic timelines usually provide better value.
Start with a free discovery week. We'll analyze your project, deliver a detailed plan, and build a proof of concept — before you commit to anything.
Not every development company is the right fit. Here's what makes us different.
We've been doing this since 2014. That's enough time to see what actually works in production, which shortcuts lead to technical debt, and how to build apps that are still running smoothly years after launch.
React isn't just another tool in our kit. It's our primary framework. We've built everything from simple admin dashboards to complex SaaS platforms. Deep expertise means better architecture decisions and faster problem-solving.
Our work is in production serving real users at scale. Rocket League Garage alone handles 5M+ users. We know what it takes to build apps that perform under load and keep working reliably over time.
You'll know what's happening at every stage. Weekly demos, clear communication, honest estimates. When problems come up, we flag them early. The goal is predictable delivery, not project management theater.
What most impressed me about ProductCrafters was their dedication to my project and understanding of our goals. They were very honest and transparent throughout the entire process.
They were flexible, and it was easy to work with them on a day-to-day basis. Their brilliant ideas were critical to the project success.

Out of over 40 applicants, we selected ProductCrafters based on their experience, technical expertise, and cost estimate. The team showed deep technical expertise, a strong work ethic, and honesty.

The team has honest billing practices and creates incredible value for the cost. Working with ProductCrafters has saved us hundreds of thousands of dollars compared to domestic firms.

The quality of their code makes them a valuable partner. They thought holistically about solutions and brought up all-encompassing ideas.

Their insightful advice has maximized the application's performance. We're actually learning things from ProductCrafters that we can adapt and use in other applications.

Oleg Kalyta
Founder & AI LeadBuilding your first product? We've helped dozens of startups go from idea to funded company. Here's our approach to startup web development.
Most startup ideas don't need a full product to prove they work. We build MVPs in 8-12 weeks that test core assumptions with real users. You get market feedback before committing to a larger build.
See example:HealifyIdea to $2M funding in 6 months→Technical due diligence is part of most funding rounds. We build with clean code, proper documentation, and scalable architecture that won't raise red flags when investors bring in their technical advisors.
See example:Breeze$2.5M raised, passed technical due diligence→Startup money is precious. We recommend technologies and hosting setups that minimize costs early while leaving room to scale. No gold-plating, just what you need to get traction.
See example:Finsu$500K raised, scaled to 50K+ users→Your product will change. A lot. We build in a way that makes pivots and feature changes straightforward. The codebase stays maintainable even as requirements evolve.
See example:Playback Rewards600K+ users, continuous feature evolution→You're busy with fundraising, sales, and a hundred other things. We handle the entire technical side so you can focus on growing the business. One team, one point of contact.
See example:RaisalAcquired by Iuvity, end-to-end delivery→Building for a larger organization? Enterprise projects come with their own requirements. Here's how we handle them.
Integration with Active Directory, Okta, Auth0, or your existing identity provider. Users authenticate once and access everything they need. Role-based permissions ensure people only see what they should.
When you need to track who did what and when, we build it in. Audit logs, data retention policies, and the documentation your compliance team requires. HIPAA, SOC 2, GDPR, we've worked within these frameworks.
For applications that can't go down, we design redundant systems with failover, load balancing, and disaster recovery. Monitoring and alerting catch problems before they affect users.
Enterprise environments have existing systems. ERPs, CRMs, legacy databases, custom internal tools. We build integrations that work reliably and handle edge cases gracefully.
Whether you have 500 employees or 50,000, the application needs to perform. We architect for the load you expect and build in room to grow.
