No Buzzwords. No Fluff. Just the Real Path to Building Scalable On-Demand Platforms.

 

Before I actually talk and share insights, I want to address the elephant in the room.
As we step into 2025, the internet is flooded with cookie-cutter content written purely for SEO. You’ve probably seen countless blog posts titled “How to Build an App Like XYZ”—and while they may rank well on Google, most are written by content writers with zero technical experience. Their goal? Drive traffic. And sure, with high-ticket projects like DoorDash-style platforms, some clicks may convert into leads.

But here's the problem: these articles are all noise.
They recycle the same formula—research, plan, choose a tech stack like MERN or PHP—without offering any real, nuanced insight into what actually goes into building a complex, scalable product. The truth is, most of these writers have never touched a line of code or sat through a product sprint, and it shows.

I'm not here to spoon-feed you generic steps or push you toward whatever tech stack is trending. I’ve spent years as a developer, and today I work directly with founders to architect and launch products—often through unconventional, lean, and highly efficient approaches that save both time and budget without compromising on quality or scalability.

So, why should you listen?

Because I’ve seen what works—and more importantly, what doesn’t.
I’ve worked with founders who burnt through their entire budget before even reaching launch. I’ve seen teams collapse under tech debt, or get trapped in endless development cycles because no one thought through the roadmap realistically. And I’ve helped teams course-correct when it mattered most.

If you’re here looking for quick  solutions or shortcuts, this article probably isn’t for you. But if you're serious about understanding what it really takes to build a scalable DoorDash-like platform—and want insights from someone who’s been in the trenches—then read on.

In This Guide, We’ll Cover:

• The tech stacks that scale vs. the ones that only sound good on paper

• Tools, frameworks, and architectures that actually work

• A practical approach to building fast without cutting corners

• The real cost of building an on-demand delivery app in 2026
  
  

This isn't a theory. This is what’s working in the real world right now.

Let’s get into it

The Tech Stack

Before diving into the specific tech stack and frameworks, let’s first break DoorDash down into a few core components. This will help us better understand how each part works and how the tech stack supports it.

The Four Core Layers:

1. Content + Visual Layer
2. Commerce
3. Operations
4. Maintenance & Support

---

1. Content + Visual Layer (The App Interface)

When we talk about the content and visual layer, we're referring to the app itself — the banners, UI layout, push notifications, ads, and all the dynamic content users interact with.

Traditionally, many teams opt for a custom backend (built in Node.js, PHP, etc.) to manage this. That includes handling functionality like updating banners, changing layouts, managing content, sending notifications, etc. But there are two major challenges with this approach:

• You not only have to build the backend, but also design and develop an admin panel from scratch.
  
  

• Making the app dynamic (e.g., updating layouts for different festivals or events without forcing users to update the app) becomes complex, time-consuming, and difficult to scale.
  
  

So, what's the better alternative?

Enter: Headless CMS

If you're unfamiliar with headless CMS platforms, think of them as backend-only content management systems. They don't include a frontend, so you can fully customize how and where the content appears. They're SaaS-based open source self hosted, scalable, and allow dynamic content updates without requiring app updates from users.

With a headless CMS, you can:

• Easily manage banners, layouts, promotions, and UI changes.

• Schedule and launch marketing campaigns.

• Update your app’s content on the fly.
  
  

Building this level of flexibility manually with Node or any custom backend could take 6–8 months, a large dev team, and tons of QA/testing.

Why this approach works

We’ve used this model to launch multiple MVPs quickly, and many billion-dollar apps use the same strategy. For example, Tata’s NEO app (used by millions) is powered by Sanity.io – a leading headless CMS:
🔗 Sanity + Tata Case Study

This kind of content layer is often referred to as a DXP (Digital Experience Platform).

Recommended Headless CMS Platforms

Some great options to consider:

• Directus(free open source )

• Sanity ( SaaS )

• Payload CMS (free open source )

• Contentful( SaaS )
  
  

These platforms are either open-source or SaaS-based, and depending on your choice, you can build out the content infrastructure in under a month (especially if your UI is ready). Using a headless CMS can reduce development time by up to 60%.

🔗 Best Headless CMS in 2025

 

2. Commerce (The Transactional Core)

Now let’s talk about the heart of any DoorDash-style platform: commerce.

This is where most MVPs start bleeding time, money, and sanity.

We’re talking about:

• Product and menu management
  
  

• Cart and checkout flow
  
  

• Payments
  
  

• Multi-role access (admin, vendor, delivery agents)
  
  

• Discounts, taxes, and inventory logic
  
  

• Order status, refunds, and more
  
  

Most founders make the same mistake: they try to custom-build the entire commerce engine from scratch. Sounds reasonable in theory — until you realize you're basically reinventing Shopify, but for your app.

Here’s what that really means in practice:

• Building a merchant panel, admin panel, and delivery dashboard from the ground up
  
  

• Architecting a secure checkout and payment integration
  
  

• Handling edge cases like partial refunds, stock sync, surge pricing, delivery zones...
  
  

• Testing for months because one broken flow means real money lost
  
  

If you're aiming to launch in under 6 months — forget it. Unless you have millions in funding and a team of 20+ engineers, you’ll burn out before v1 hits production.

So, what’s the smarter route?

Just like how we use headless CMS for content and UI flexibility, the same concept applies here — plug into battle-tested commerce infrastructure that’s:

• Modular
  
  

• Open-source or SaaS
  
  

• Customizable
  
  

• Built to scale from day one
  
  

Tools We Recommend for the Commerce Layer:

1. Medusa.js (Open Source)

A headless commerce engine built for developers. Medusa gives you a customizable backend with APIs for cart, checkout, products, orders, and more — plus pre-built admin dashboards.

• Built with Node.js
  
  

• Supports multi-vendor and plugin architecture
  
  

• Super fast to set up and iterate on
  
  

• Ideal if you want flexibility but still need speed
  
  

🔗 Medusa Commerce

2. Commerce Layer

If you’re going global or planning multi-region pricing, this is a killer SaaS option.

• API-first, with native support for multi-currency and localization
  
  

• Integrates well with headless frontends and CMS platforms
  
  

• Scales with your business without the overhead
  
  

🔗 Commerce Layer

3. CommerceTools

This one is used by enterprise-level companies. Think of it as the Shopify Plus of headless commerce.

• Extremely robust
  
  

• Best-in-class APIs
  
  

• Ideal for businesses expecting high traffic and complex commerce rules

What About Internal Tools Like CRM, Admin Dashboards, or Delivery Ops?

Here’s another common trap: teams spend months building internal tools from scratch — just to manage data, orders, and users.

Again, don’t build unless you have to.

Use tools like:

• ToolJet – open-source, drag-and-drop internal tool builder
  
  

• Retool – the go-to for building fast admin panels with real-time DB/API integrations
  
  

• Appsmith – a solid open-source alternative for quick dashboards
  
  

These platforms connect to your DB, APIs, or services (like Medusa or Firebase) and let you build admin tools, vendor portals, delivery dashboards — whatever you need — in a matter of days, not months.

TL;DR: Commerce, the Smart Way

 

This strategy lets you focus on differentiation, not infrastructure. You're not building the next Stripe or Shopify — you're building a product experience that sits on top of proven infrastructure.

In the next section, we’ll break down the Operations layer — how to handle logistics, delivery tracking, routing, and notifications without going broke or insane.

Let’s keep going.

3. Operations Layer (Logistics, Fulfillment & Real-Time Systems)

This is the part no one talks about enough — yet it’s the difference between an app that works on demo day and one that survives in the real world.

You’ve got the UI (thanks to headless CMS).
You’ve got transactions flowing (via modern commerce tools).
But here comes the real challenge: Operations.

In an on-demand platform like DoorDash, operations = everything that happens after the user hits "Place Order."

This includes:

• Assigning orders to the right vendor
  
  

• Dispatching drivers in real time
  
  

• Route optimization
  
  

• Live order tracking
  
  

• Delivery status notifications
  
  

• Handling delays, cancellations, substitutions, escalations
  
  

And here’s the kicker: it all has to happen in real time.

Trying to build this layer from scratch? That’s an engineering black hole.

What You’re Really Dealing With:

• Geo-coordination between vendors, riders, and customers
  
  

• State machines for every order (Pending → Accepted → Out for Delivery → Delivered)
  
  

• Websockets or Pub/Sub systems for live tracking
  
  

• Notifications across push, SMS, email
  
  

• Dispatch logic to assign the right driver for the right job
  
  

• Fallback systems for when drivers cancel or vendors are unavailable
  
  

It’s more than just code. It’s orchestration.

So How Do You Build This Without Burning a Year?

Break it into modular services and lean on tools that already solve 80% of the problem.

Here’s how we approach it:

1. Real-Time Tracking & Geo Services

Instead of building from scratch :

• Use Google Maps API or Mapbox for geolocation, route ETA, and mapping.
  
  

• For tracking, plug in Ably, Pusher, or Socket.io (if you’re self-hosting).
  
  

• For serverless pub/sub, Firebase Realtime DB or Supabase works great.
  
  

You’ll get:

• Live location updates
  
  

• ETA predictions
  
  

• Re-routing capabilities
  
  

2. Order Lifecycle Management

Model every order like a state machine. This helps you handle complex workflows with edge cases (order canceled, rider rejected, item out of stock, etc).

Tools you can use:

• XState (JavaScript library for managing state machines)
  
  

• Or write your own with clean, predictable transitions in backend logic
  
  

If you're using Medusa.js or similar, you can hook into its event system to manage these workflows.

3. Driver Assignment & Dispatch Logic

This is where things get tricky.

You’ll want a system that can:

• Check driver availability
  
  

• Calculate who’s nearest
  
  

• Assign based on zones, traffic, or delivery load
  
  

• Reassign if a driver declines
  
  

Unless you’re Uber, don’t build this from scratch.

Instead, use:

• HyperTrack – Real-time logistics APIs with driver tracking and dispatching
  
  

• Onfleet – End-to-end delivery management platform with SDKs
  
  

• Bringg, Shipsy, or Tookan for more enterprise-grade logistics
  
  

These tools give you:

• Driver mobile apps
  
  

• Real-time dashboards
  
  

• Dispatch automation
  
  

• Notifications baked in
  
  

4. Notifications (Push, SMS, Email)

For real-time comms, plug into:

• Firebase Cloud Messaging (FCM) – for push notifications
  
  

• Twilio / MessageBird – for SMS alerts
  
  

• SendGrid – for email confirmations
  
  

Use queue-based systems like BullMQ, RabbitMQ, or Redis Streams to avoid overloading your servers during high traffic spikes.

Why This Works

You’re not guessing. You’re integrating proven infrastructure designed to handle high-load, real-time operations. You’re building a lean backend focused on orchestration, not low-level plumbing.

Most importantly, you’re shipping faster — without sacrificing user experience.

 

---

 

TL;DR: Operations Layer Setup

This structure powers logistics behind platforms like Zomato, Swiggy, and yes — DoorDash. It’s not about doing it all in-house, it’s about stitching together tools that let you focus on what makes your product unique.

 

---

 

Up next: the Maintenance & Support Layer — how to scale without drowning in bugs, downtime, and chaos. Let’s finish strong.

 

4. Maintenance & Support Layer (Scaling Without the Chaos)

So you’ve built the UI.
You’ve plugged in modern commerce.
You’ve handled real-time ops.

Now what?

You’ve launched. People are ordering. Vendors are onboarding. Drivers are delivering.

But then the real world kicks in:

• A payment bug breaks checkout for 20% of users
  
  

• An order gets stuck in "Preparing" and no one knows why
  
  

• A vendor calls asking for support but there’s no admin view of their orders
  
  

• Your server CPU spikes to 99% during lunch hour
  
  

This is where most apps fall apart.

Here’s the truth:

Launch is not the finish line. It’s just Day 1.
If you don’t have solid observability, monitoring, and tooling in place, you’ll be drowning in chaos within a month.

And What If You Don’t Have DevOps?

Good news: you don’t need a dedicated DevOps team to scale in 2025.

If you follow the architecture we outlined — using DXP tools like Sanity, Strapi, or Directus, and commerce platforms like Medusa, Commerce Layer, etc. — you’re already making life 10x easier.

Why?

Because these platforms come with their own cloud infrastructure.

• Sanity, Contentful, Directus Cloud, and others offer fully managed services — they handle scaling, performance, and deployment for you.
  
  

• Medusa now has a hosted cloud platform (and you can also self-host if needed).
  
  

• Even open-source tools like Strapi can be deployed with one click on Render, Railway, or Vercel — no need to touch AWS, configure EC2 instances, or hire a senior DevOps engineer at $150K/year.
  
  

This means:

• No worrying about uptime or infrastructure
  
  

• No sleepless nights trying to debug why your app isn’t scaling
  
  

• No expensive AWS bills from misconfigured resources
  
  

• No breaking your head over CI/CD pipelines, load balancers, or auto-scaling groups
  
  

You can launch and run like a top-tier tech company — without building like one.

TL;DR: Maintenance & Scaling Without DevOps

 

---

 

So unless you really need custom infra or regulatory compliance — there’s no reason to go full AWS from day one.

Don’t overbuild. Don’t overhire. Don’t overthink it.

Use platforms that handle the heavy lifting, so you can stay laser-focused on building a great product — not a fragile tech empire.

Once it’s all connected and after launch, here are a few 3rd-party tools you’ll need to use:

Tech Stack Summary (2025-Ready)

 

 

Book a free call to get access to the system architecture and high-level design—100% free.

 

Note: In this tech stack solution, we're using the best tools available and seamlessly connecting each of them together. Yes, this entire stack is microservices-based, offering unlimited scalability — with no cookie-cutter solutions. We've provided you with a clear roadmap to understand the architecture. Now it's up to you to select the platforms you need, connect them, and launch.

Let's Talk About Pricing

When estimating the cost of running this modern tech stack at scale, here’s a realistic scenario:

Hypothetical Usage

• 5 million users
  
  

• Approximately 50 million API calls per month
  
  

Based on this scale — and depending on which platforms you choose (CMS, commerce engine, real-time services, etc.) — the annual infrastructure and platform cost typically ranges between $100,000 to $300,000.

And to operate and maintain this stack efficiently, you’ll only need a small team of 4 to 5 developers.

What If You Build a Custom Backend?

Now, let’s compare this with a fully custom-built backend approach:

• While server costs might be slightly lower, the Total Cost of Ownership (TCO) is significantly higher.
  
  

• You would require a team of at least 20+ developers to build, maintain, and scale the system.
  
  

• Annual costs can easily exceed $1 million, factoring in:
  
  

• Infrastructure and DevOps
  
  

• Backend development
  
  

• QA and support
  
  

• Maintenance and scaling complexities
  
  

Summary

Modern Headless + Microservices Stack

• $100,000 to $300,000 per year
  
  

• Lean team of 4–5 developers
  
  

• Modular, scalable, faster to iterate
  
  

Fully Custom Backend

• $1,000,000+ per year
  
  

• Large team of 20+ developers
  
  

• Slower development, higher maintenance, increased technical debt

Development Cost Breakdown

Assuming you’re using the best-of-breed tools and platforms we’ve outlined in the tech stack, the cost of development will largely depend on the scope, scale, and specific features you want to build.

For a typical DoorDash-style on-demand platform, here's a realistic range:

• Initial Development Cost:
  $80,000 to $200,000+
  
  

This estimate includes:

• Building the customer-facing app (mobile and/or web)
  
  

• Vendor/merchant portals
  
  

• Admin dashboards
  
  

• Integrations with CMS, commerce engine, real-time ops, and third-party tools
  
  

• QA, testing, and initial deployment
  
  

Factors That Influence Cost:

• Number of platforms (Web, iOS, Android)
  
  

• Level of customization and UI design
  
  

• Real-time logistics and tracking complexity
  
  

• Integrations (payment gateways, notifications, analytics, etc.)
  
  

• Admin tools and operational dashboards
  
  

• Launch readiness (MVP vs full-scale v1)
  
  

Summary

• Lean MVP with modern stack: ~$80K–$120K
  
  

• Full-featured platform with complex ops: ~$150K–$250K+
  
  

• Cost-effective if you follow a modular, scalable architecture from day one

Development Cost: Custom Backend with Node.js

If you're building everything from scratch using Node.js, expect significantly higher costs and longer timelines.

Estimated Cost

$300,000 to $1,000,000+

What’s Included

• Fully custom backend architecture
  
  

• Customer apps (web and/or mobile)
  
  

• Vendor and admin portals
  
  

• Real-time logistics, notifications, and payments
  
  

• QA, testing, deployment
  
  

Key Cost Drivers

• Number of platforms (Web, iOS, Android)
  
  

• Real-time features and operational complexity
  
  

• Custom integrations and UI
  
  

• Team size (15–25 developers)
  
  

• Longer timelines (9–18 months)
  
  

Summary

• Lean MVP: ~$300K–$500K
  
  

• Full-featured platform: ~$600K–$1M+

conclusion

Pricing can vary significantly based on the company, country, and agency you work with. In some cases, you’ll find custom development agencies offering to build DoorDash-style platforms for as low as $20,000. But in reality, these solutions are often mediocre, not scalable, and rarely meet the promises made. Overpromising and under delivering is common at that price point.

If you're serious about building a high-quality, scalable product, here’s what you can realistically expect:

• Using best-of-breed tools (headless CMS, modular commerce, etc.):
  Development cost for a solid MVP ranges between $80K to $120K, with a timeline of 4 to 5 months.
  
  

• Fully custom backend with Node.js (enterprise-grade, built by top-tier agencies):
  Expect to spend $300K to $500K+, with a development timeline of 12 to 18 months for a robust, scalable platform.

Final Thoughts for Early-Stage Founders

To all early-stage founders out there — don’t get overwhelmed by complex tech stacks. The key is not to build everything from scratch and not to reinvent the wheel.

Instead, use the best tools available, focus on what makes your product unique, and launch as quickly as possible. Custom solutions make sense only if you have significant funding, a dedicated team, and a long-term roadmap.
