If data apps were 10x or 100x easier to build, what would get built?

Category: Trends
Imagine it’s 1990. You’re on a family vacation. You bring along your trusty film camera, but every shot is a deliberate decision. Each roll holds just 24 or 36 exposures, and every click of the shutter feels like a small wager: “Is this photo worth it?” Developing film costs money and takes time. Most of the shots? Blurry, overexposed, or missed moments.
Fast forward to today. Your smartphone doesn’t just take tens of photos.. it takes thousands. Each shot costs nothing. You retake as many as you like and share them instantly. Suddenly, photography as a discipline shifts. It’s no longer about preserving special occasions; it’s about capturing everything. Your morning coffee, a fleeting sunset, a funny sign. Photos, once scarce and intentional, are now abundant and instinctive.
This seismic shift in behavior didn’t just change how many pictures we take. It changed why we take them. It built new ecosystems, like Instagram, Google Photos that never would have existed when photography was slow, costly, and rare.

The question is: what happens when building data apps becomes this fast, this cheap, and this effortless?
🌐 Emergent Ecosystems and Behaviors
Here are some observations on use-cases we get asked about on the daily for Preswald:
1️⃣ Personal Analytics Apps
Today, no company would dedicate engineering resources to build a custom dashboard for a single sales rep. But what if the sales rep didn’t need engineers?
"Build me a dashboard with my daily sales calls, deal sizes, and close rates from Salesforce and HubSpot."
Within minutes, you can connect to APIs, model the data, and spin up a dashboard. It refreshes live, tailored specifically to that individual’s workflow. When personal analytics are this easy to build, every employee has access to insights that optimize their productivity—not just company-wide metrics.
2️⃣ Hyper-Localized Apps
Would anyone invest in a dashboard to track food waste patterns at a single restaurant? Not today. Too niche, too expensive. But with a 100x cost reduction, the restaurant manager can:
"Pull data from our POS system, inventory tracker, and shift schedules to show food waste by dish, broken down by time of day and chef."
Now, they’re making decisions (like cutting menu items or tweaking portion sizes) in real-time. Businesses can address hyper-specific operational challenges that were never worth the effort before.
3️⃣ Ephemeral Data Apps
Data Apps exist for moments, like a conference, a product launch, a natural disaster. Example: An organizer builds a dashboard tracking foot traffic and Wi-Fi pings during a festival, which deactivates the moment the event ends. Imagine running a weekend festival. Would you spend tens of thousands of dollars to build a custom app for monitoring food vendor sales, bathroom wait times, and foot traffic? Never. But now, you can prompt:
"Create a dashboard showing foot traffic from Wi-Fi pings, vendor sales from Stripe, and live bathroom wait times from IoT sensors."
Within hours, you’re optimizing vendor placement and redirecting crowds to less congested areas. Temporary, hyper-specific apps become commonplace, improving experiences on the fly.
4️⃣ Machine-to-Machine Data Apps
Machines interact with apps autonomously. E.g., IoT sensors reporting metrics, triggering real-time apps for supply chain optimization or predictive maintenance.
The Bottleneck of Today
Even today, building a data app is like taking a photo in the early 1990s. Every decision has to justify its cost. Data apps today are reserved for the most critical use cases:
🔹 Executive dashboards for quarterly revenue.
🔹 Enterprise-scale BI tools for company-wide KPIs.
🔹 Predictive analytics for million-dollar decisions.
It takes a team of specialists (data engineers, analysts, and developers) to get even these off the ground. Every step is expensive, slow, and manual:
-
Connection
-
Fivetran, Airbyte, or custom ETL scripts pull data from various sources. This requires configuring connectors, handling schema drift, reliable sync.
-
Every new source adds marginal cost in both time and complexity
-
-
Transformation
-
Tools like dbt enable SQL-based transformation, but they assume skilled practitioners who can clean, normalize, and model data effectively
-
Models are brittle and require ongoing maintenance as business logic evolves
-
-
Application Development
-
Building the frontend and backend of a data app requires engineers to choose frameworks (React, Flask, etc.), provision infrastructure (AWS, GCP, or serverless), and manage APIs.
-
Even small apps demand a full software stack, making niche or temporary applications cost-prohibitive.
-
-
Deployment & Maintenance
-
Deploying and scaling data apps requires CI/CD pipelines, monitoring systems, and ongoing maintenance to ensure performance and uptime.
-
Operational overhead becomes untenable for non-critical apps.
-
Smaller, experimental ideas never see the light of day. No one is spending $50K and six weeks building a dashboard for hyper-local, temporary, or personal use cases. The ROI just isn’t there. But what happens when that cost drops by 10x? Or 100x?
When the effort required to build data apps approaches zero, the technical possibilities expand in several dimensions:
Data App Architectural Shifts
This transformation requires rethinking the architecture of data platforms:
-
Unified Abstractions. Platforms must consolidate integration, transformation, and visualization into a single seamless flow.
-
Event-Driven Models. Real-time triggers replace batch processes, so apps respond dynamically to changing conditions.
-
Composable Microservices. Data apps leverage composable building blocks (APIs, serverless functions) to scale modularly.
Invisible, Ubiquitous, Second Nature
When data apps become this easy to build, they stop feeling like “apps” at all. They’re not big projects. They’re not even decisions. They’re just the natural way to solve problems. When you lower the barriers to creation, the world doesn’t just change a little. It changes completely.
