Trello didn't just create a product; it popularized an entire workflow methodology: the Kanban board. Its simplicity, visual appeal, and effectiveness made it a global success. For Founders, CTOs, and Product Managers, the idea of building a custom, Trello-like web application-one perfectly tailored to their unique business logic, integrated with their ERP, or enhanced with proprietary AI-is incredibly compelling.
However, the first and most critical question is always: How much will it cost?
The answer is rarely a single number. Building a custom web app like Trello is a strategic investment, and its price is a function of complexity, feature set, and your choice of development partner. As a world-class software development and IT solutions company, Cyber Infrastructure (CIS) is here to provide the transparent, detailed breakdown you need to move from idea to budget approval. We'll dissect the cost by feature, team, and technology, giving you a clear path to launching your next-generation workflow platform.
This article, which expands on our initial analysis, is designed to be your definitive guide to the cost to build a web app like Trello, ensuring your project is future-ready and financially sound.
Key Takeaways: Trello-Like App Development Cost
- 💰 Cost Range: A Minimum Viable Product (MVP) for a Trello-like app typically costs between $50,000 and $120,000. A full-featured, enterprise-grade platform can easily exceed $300,000+.
- 🛠️ Core Driver: The total development cost is primarily driven by the total development hours, which are directly proportional to the complexity of the feature set.
- 💡 Strategic Savings: Leveraging a high-maturity (CMMI Level 5) offshore partner like CIS can reduce the total development cost by an average of 40-60% compared to US-based agencies, without sacrificing quality or security.
- 🚀 MVP Focus: Prioritize core features like User Authentication, Kanban Boards, and Task Management for the MVP to achieve a faster time-to-market and validate your concept.
- 🔒 Risk Mitigation: Choose a partner offering a 2-week paid trial and a free-replacement guarantee to de-risk your investment in custom software development.
The Core Cost Drivers: Features, Team, and Tech Stack
Before we dive into specific dollar figures, we must establish the three non-negotiable variables that dictate the final price tag of your custom web application. Ignoring any of these is a common mistake that leads to budget overruns and project failure.
1. Feature Complexity (The 'What') 💡
This is the most significant cost driver. A simple Kanban board is easy; a board with real-time AI-powered predictive scheduling, complex integrations, and custom reporting is not. Every feature translates directly into development hours.
2. Development Team Structure & Location (The 'Who') 🌍
The hourly rate of your development team varies drastically by location (North America, Western Europe, or High-Maturity Offshore). Furthermore, you need a cross-functional team: a Project Manager, UI/UX Designer, Front-end Developer, Back-end Developer, and QA Engineer. The size and expertise of this team will define the velocity and cost.
3. Technology Stack (The 'How') 💻
Your choice of technology impacts long-term scalability and maintenance costs. A modern, robust stack (e.g., React/Vue for the front-end, Node.js/Python for the back-end, and a secure cloud environment) is essential for a scalable cloud-based app. Choosing an outdated or niche stack can lead to higher maintenance costs and difficulty finding talent later.
Checklist: Key Cost-Driving Factors
- Real-Time Updates: Does the app require instant updates (e.g., WebSockets)? This adds complexity.
- Third-Party Integrations: How many APIs (Slack, GitHub, Salesforce, etc.) need to be integrated? Each one is a mini-project.
- Custom UI/UX: Are you using a template or a fully custom, high-fidelity design? Custom design adds significant upfront hours.
- Security & Compliance: Does your app need to be HIPAA, SOC 2, or GDPR compliant? This requires specialized engineering and auditing.
- AI/ML Components: Are you adding features like automated task prioritization or sentiment analysis? This requires a dedicated AI/ML Rapid-Prototype Pod.
Trello-Like App: MVP vs. Full-Featured Platform Cost Breakdown
The most effective way to estimate the cost is by breaking the project down into development hours. We use a two-phase approach: the essential MVP to validate the market, followed by advanced features for scaling and enterprise adoption. The following table provides a high-level estimate based on our experience with similar custom workflow applications.
Estimated Development Hours for a Trello-Like Web App
| Feature Category | MVP (Minimum Viable Product) Hours | Advanced/Enterprise Features Hours |

| User Authentication & Profiles (Sign-up, Login, Password Reset) | 120 - 180 | + 80 - 120 (SSO, Two-Factor Auth, Role-Based Access) |
| Kanban Board & Core Task Management (Create/Move/Edit Cards, Lists, Boards) | 250 - 400 | + 150 - 250 (Custom Fields, Card Templates, Advanced Filtering) |
| Notifications & Activity Log (Basic in-app alerts) | 80 - 120 | + 100 - 150 (Email/Push Notifications, Custom Alert Rules) |
| File & Media Management (Basic attachment upload) | 60 - 100 | + 120 - 180 (Cloud Storage Integration, Version Control) |
| UI/UX Design & Front-end Development | 300 - 500 | + 200 - 350 (Custom Themes, Accessibility Compliance) |
| Back-end & Database Setup | 200 - 350 | + 150 - 250 (Microservices Architecture, Load Balancing) |
| Quality Assurance (QA) & Testing | 150 - 250 | + 150 - 250 (Automated Testing, Performance Engineering) |
| Total Estimated Hours | 1,160 - 1,850 Hours | + 950 - 1,500 Hours |
Phase 1: Minimum Viable Product (MVP) Cost
Focusing on the MVP (1,160 to 1,850 hours) allows you to launch quickly, gather real user feedback, and secure further funding. This version is the core, functional Kanban system. Using an average blended offshore rate (which we will detail next), the cost for this MVP typically falls in the range of $50,000 to $120,000.
Phase 2: Advanced Features and Scaling Cost
Once validated, you move to Phase 2, adding features like calendar view, custom reporting, advanced permissions, and critical integrations. This is where your app transitions from a simple tool to a powerful SaaS application on AWS or Azure. The additional 950 to 1,500+ hours, plus the cost of ongoing maintenance and cloud infrastructure, push the total investment into the $200,000 to $500,000+ range, depending on the depth of enterprise features and AI integration.

Beyond Launch: Essential Post-Development Costs
A common pitfall for founders is focusing solely on the development cost. A web app is a living product, and you must budget for its ongoing life cycle. These costs typically begin immediately after the MVP launch and scale with your user base.
The Three Pillars of Post-Launch Cost 🏗️
- Maintenance & Support (The largest ongoing cost): This includes bug fixes, security patches, library updates, and ensuring compatibility with new operating systems or browsers. Budgeting 15-20% of the initial development cost per year is standard for comprehensive support.
- Cloud Hosting & Infrastructure: Trello is a high-traffic application. Your custom app will require scalable cloud services (AWS, Azure, Google Cloud). Costs depend on data storage, bandwidth, and the complexity of your architecture. Expect to pay anywhere from $100/month for a small MVP to several thousand dollars per month for a high-traffic enterprise platform.
- Feature Enhancement & Scaling: To remain competitive, you must continuously add new features. This is where a flexible engagement model, like a dedicated cross-functional POD (Project-Oriented Delivery), is most effective for continuous development sprints.
2026 Update: AI and Emerging Tech Impact on Project Management App Costs
The most significant shift in custom software development is the integration of Artificial Intelligence. For a Trello-like app, AI is no longer a luxury; it's a competitive necessity. While AI features add to the initial development cost, they deliver exponential ROI through efficiency gains.
AI-Enabled Features Driving Value (and Cost) 🤖
- Automated Task Summaries: GenAI models can summarize card comments and activity logs into a concise daily brief, saving managers hours.
- Predictive Scheduling: AI analyzes historical task completion data to predict realistic deadlines and flag potential bottlenecks before they occur.
- Intelligent Task Assignment: Based on team member skills, current workload, and past performance, the system automatically suggests the best person for a new task.
- Conversational AI/Chatbot: A built-in chatbot for quick task creation, status updates, and Q&A, reducing reliance on the main interface.
Integrating these features requires specialized talent from an AI Application Use Case POD, which will increase the initial development hours. However, the resulting platform will be a true differentiator, moving beyond simple task tracking to become a strategic business intelligence tool.

Frequently Asked Questions
What is the absolute minimum cost to build a basic Trello-like MVP?
The absolute minimum cost for a functional, basic Trello-like MVP (core Kanban board, user authentication, and task creation) is typically in the $50,000 to $75,000 range. This assumes a highly efficient, high-maturity offshore development team and a strict focus on only the essential features (around 1,100-1,300 development hours).
How long does it take to build a Trello-like web app MVP?
Based on the estimated 1,160 to 1,850 development hours, a dedicated, cross-functional team (PM, Designer, 2 Developers, QA) can typically complete the MVP phase in 3 to 5 months. This timeline includes discovery, design, development, and rigorous testing.
What is the biggest mistake companies make when budgeting for a custom web app?
The biggest mistake is failing to budget for post-launch maintenance and feature scaling. Many companies allocate 100% of their budget to the initial build, only to find they lack the resources to fix bugs, update security, or add critical features after launch. Budgeting an additional 15-20% of the initial cost annually for maintenance is a necessary strategic step.
Can I get a fixed-price quote for my Trello-like app?
Yes, CIS offers both Fixed-Price Project and Time & Material (T&M) models. A fixed-price quote requires a highly detailed, locked-down scope document. For projects with evolving requirements, the T&M model or a dedicated POD (Cross-functional team) is often recommended for maximum flexibility and efficiency.
