Launching a classified app is more than building a platform; it's about creating a thriving digital ecosystem. You have the vision for a go-to marketplace, but the technical hurdles are daunting: ensuring scalability for millions of users, implementing ironclad security for transactions, and creating an intuitive user experience that keeps people coming back.
At Developers.dev, we transform these challenges into your competitive advantage. We don't just write code. We partner with you to engineer a high-performance, feature-rich, and future-proof classified platform, leveraging our team of over 1000 in-house experts to bring your vision to market with precision and speed.
Here's how we provide the certainty and expertise you need to launch a successful classified app.
Your users' data and your business's reputation are on the line. As a SOC 2 and ISO 27001 certified company, we build security into every layer of your application, from infrastructure to code, protecting you and your customers from threats.
Dreaming of millions of users? We build for it from day one. Our architects specialize in cloud-native and microservices-based designs that handle viral growth spikes without compromising performance, ensuring a seamless experience for your expanding user base.
We don't use freelancers or contractors. Your project is handled by our dedicated, full-time team of over 1000 vetted professionals. This ensures consistent quality, accountability, and a deep-seated commitment to your success.
Your idea is your most valuable asset. We ensure it stays that way. Our agreements guarantee a 100% transfer of all intellectual property to you. Your proprietary source code, designs, and data belong to you, and only you.
Gain a competitive edge with intelligent features. We integrate AI and machine learning for everything from automated content moderation and fraud detection to personalized recommendations and dynamic pricing, creating a smarter and safer user experience.
Chaos kills projects. Our CMMI Level 5 appraisal-the highest level of process maturity-means we deliver consistently, on time, and on budget. We minimize risks and maximize efficiency, providing you with predictable, high-quality outcomes.
Our relationship doesn't end at launch. We are your long-term technology partner, offering ongoing maintenance, 24x7 helpdesk support, and growth marketing services to ensure your platform continues to evolve and thrive in the market.
We stand by the quality of our team. If you're not satisfied with a developer's performance, we offer a free replacement with zero-cost knowledge transfer. This ensures your project momentum is never compromised.
Benefit from the cost-efficiency and talent pool of our Indian delivery centers, all while receiving seamless communication and project management aligned with your local timezone (USA, EMEA, Australia). It's the best of both worlds.
We offer a comprehensive suite of classified app development services designed to cover every stage of your project's lifecycle. From initial strategy to post-launch scaling, our expert PODs (Cross-functional teams) provide the specialized skills needed to build a market-leading platform.
We build your platform from the ground up, tailored precisely to your business logic, target audience, and revenue goals. This bespoke approach ensures a unique, defensible product that stands out from template-based competitors.
Engage users and increase conversions by showing them the most relevant listings. Our AI/ML pods develop and integrate sophisticated algorithms that learn from user behavior to provide personalized recommendations.
A great classified app is defined by its search. We implement powerful, faceted search systems with features like geo-location, dynamic filters, saved searches, and instant auto-suggestions to help users find exactly what they need, fast.
Monetize your platform with confidence. We integrate multiple trusted payment gateways (Stripe, PayPal, Braintree) to handle listing fees, featured promotions, and user-to-user transactions with PCI-compliant security.
Foster a safe and engaging community by enabling direct communication between buyers and sellers within your app. We build secure, real-time messaging systems with features like image sharing, canned responses, and reporting tools.
For many classifieds, location is everything. We integrate advanced mapping solutions (Google Maps, Mapbox) to allow users to search by location, view listings on an interactive map, and get directions.
Protect your community and brand from inappropriate content at scale. We deploy AI-powered moderation systems that can automatically flag or remove text and images that violate your terms of service, 24/7.
Trust is the currency of any marketplace. We develop comprehensive user profile systems with features like ratings, reviews, verification badges, and transaction history to build a self-policing and trustworthy community.
Manage your entire ecosystem from a single, powerful command center. We build custom admin dashboards that give you full control over users, listings, transactions, content, and analytics.
Reach the widest possible audience with a single codebase. Our Flutter and React Native experts build high-performance, native-like apps for both iOS and Android, reducing development time and cost without sacrificing quality.
For apps that require maximum performance, deep integration with device hardware, or the latest platform-specific features, we offer native development in Swift/Objective-C for iOS and Kotlin/Java for Android.
Extend the functionality of your platform by connecting to third-party services. We develop robust, secure, and well-documented APIs and integrate with external systems for shipping, financing, identity verification, and more.
Build on a foundation that's secure, scalable, and cost-efficient. Our certified cloud and DevOps engineers design and manage your infrastructure on AWS, Azure, or Google Cloud, implementing CI/CD pipelines for rapid and reliable releases.
Turn your app's data into actionable insights. We set up powerful analytics dashboards (using tools like Tableau, Power BI) that help you understand user behavior, track key performance indicators (KPIs), and make data-driven decisions for growth.
Development is only half the battle. Our growth marketing PODs help you prepare for a successful launch with ASO to maximize organic downloads, set up analytics, and create an initial marketing strategy to attract your first users.
Your app is a living asset that needs continuous care. We offer flexible support and maintenance plans to handle OS updates, bug fixes, security patching, and performance monitoring, ensuring your platform remains stable and secure.
To build a platform that attracts, engages, and retains users, we integrate a comprehensive set of features that create a seamless and trustworthy experience.

Templates are a great starting point, but they are a terrible place to finish. They lock you into a rigid structure, making it nearly impossible to implement the unique features that will set you apart and win the market. A "cheaper" template often leads to expensive and complex workarounds later. Our custom approach engineers your unique value proposition directly into the app's DNA, creating a scalable, secure, and defensible asset that grows with your business, not against it.
We engineered our entire delivery model to eliminate that risk. You're not hiring a "vendor"; you're partnering with a CMMI Level 5 and SOC 2 certified company with a 95%+ client retention rate. Our 1000+ experts are full-time, in-house employees who work in your timezone. We combine this with a USA-based client management team, ensuring seamless communication and a level of process maturity and quality control that is simply unattainable with freelancers or smaller shops.
Your IP security is paramount. We operate under strict, legally binding NDAs and provide a Master Service Agreement (MSA) that guarantees 100% of the IP developed is transferred to you upon full payment. Our ISO 27001 certification isn't just a badge; it's an audited proof of our commitment to rigorous data security protocols, secure infrastructure, and protecting your competitive advantage.
Absolutely. Scalability isn't an afterthought for us; it's a core architectural principle. We leverage cloud-native technologies (AWS, Azure), microservices architecture, and Site Reliability Engineering (SRE) practices to build platforms designed for high availability and performance. Our marquee clients, including Nokia, Sabre, and eBay, trust us with enterprise-scale systems. We can architect your app to grow seamlessly from 1,000 to 10,000,000 users.
This is a valid concern, and we have a straightforward, client-centric solution: a free-replacement guarantee. If any professional is not meeting your expectations, we will replace them promptly with another vetted expert from our extensive talent pool, ensuring a seamless knowledge transfer at zero additional cost to you. This is a key advantage of our 1000+ in-house employee model.
We embrace agility. We understand that market feedback can shift priorities. Our Agile development process, working in two-week sprints, is designed for flexibility. We maintain constant communication through daily stand-ups and regular sprint reviews, allowing you to adapt the project scope and priorities in response to real-world data, ensuring we are always building what matters most.
We provide complete transparency. For projects with a clearly defined scope, our Fix fees-Project model gives you a guaranteed price. For more dynamic projects, our Time & Material (T&M) model provides detailed timesheets and progress reports, so you have full visibility into where every dollar is going. We work with you to establish clear budgets and provide regular forecasts, eliminating unwelcome financial surprises.

The communication from their team in India was flawless, and the project was delivered on time. They are a true enterprise-grade partner."
"We needed to revamp our aging property listing app and integrate a host of new features, including a complex, map-based search.

Their expertise in Elasticsearch and GIS was incredible. The project was managed seamlessly in Jira, giving us full transparency. We launched the new version three weeks ahead of schedule, and user engagement is up 40%."

They built a secure, compliant, and highly effective job portal that has become the standard in our niche. Their professionalism and attention to detail are second to none."

It has fundamentally transformed our platform's user experience and safety. Their ability to deliver practical AI solutions is truly impressive."
