Let’s face it—running a small business today often feels like a balancing act between tools, subscriptions, and team capacity. You want to run efficiently without breaking the bank. That's where web apps, especially micro web apps, come in.
In this article, we’ll unpack what web apps are, when they’re the best choice, and how micro apps can be a budget-friendly alternative to bulky SaaS subscriptions—without sacrificing performance.
A web app is an interactive application that runs in your browser. Unlike a static website, a web app does things—process bookings, manage users, update content, or even chat with clients.
They’re accessible from any device, easy to maintain, and don't need to be downloaded like traditional apps. But here’s where it gets even more interesting: web apps can be built small and focused—aka micro apps—to solve specific business problems.
A micro web app is a lightweight, custom-built application that performs a single job extremely well. Unlike subscription-based platforms that offer a full suite of features (most of which you probably won’t use), micro apps are built to solve one thing—and solve it perfectly.
One of our clients runs a bee housing project. She needed a simple app to:
Post updates (with text and images) about each client’s bee house maintenance
Let clients log in to view update history
Send email notifications to clients when updates are posted
An admin dashboard for her team
A client dashboard for users
Lightweight cloud hosting on a pay-per-use model (which means she pays practically nothing monthly unless she scales to hundreds of users)
Good question! The truth is—sometimes you should.
Complex applications like full-scale CRM systems (like HubSpot or Zoho), eCommerce platforms (like Shopify), or marketing tools (like Mailchimp) are often better served through trusted SaaS providers. These platforms come loaded with features, compliance measures, integrations, and support—things that would cost tens of thousands (sometimes almost a hundred thousand too) to build even an MVP.
Here’s a quick breakdown:
One of the biggest perks of a well-built web app is automation. Micro apps can:
Send client updates automatically
Process intake forms and organize the data
Notify your team when actions are needed
Let customers self-serve and reduce support load
By offloading repetitive tasks to software, you free up human hours—letting you serve more clients without hiring more people. It’s lean, scalable growth.
Here’s where it gets really exciting.
With recent advances in LLMs (Large Language Models) like ChatGPT, Gemini, Claude, and others, small businesses now have the power to build AI-enabled micro apps that were once only possible for enterprises.
You can now build apps that:
Respond to client questions using your knowledge base
Summarize client notes or meeting transcripts
Personalize content based on customer history
Automate writing, replying, or analyzing customer feedback
The beauty? These apps are small, focused, and trained just for you. Instead of paying for a generic AI platform, you're building your own.
