A Guide to SaaS Delivery Options

When you are building a SaaS product, how you actually get it to your users is just as important as the features you are making. The way you deliver your software changes how fast you can build, how much it costs to maintain, and how your users feel when they use it.

Here are the three main ways to serve a SaaS app, along with what makes them work and when you should use them.

1. Web-First Delivery

This is the approach where you focus on the browser. It includes standard websites, Progressive Web Apps (PWAs), and things like Capacitor or WebViews that wrap a website into a mobile app.

How it works

Your app runs in the browser using HTML, CSS, and JavaScript. Your data and logic live on a remote server that the app talks to through APIs.

Common versions:

• PWAs that you can install and use with some offline support.
• Capacitor or WebView setups that let you put your web app in the App Store or Google Play.
• Kotlin WebViews for specific Android apps.

The trade-offs

If you go web-first, you get to use a single codebase, which is usually the fastest way to build. You can also push updates whenever you want without waiting for an app store to approve them. It is cheaper to maintain and great for SEO.

On the other hand, you might run into performance issues if your app is really heavy. Offline support can be tricky to get right, and sometimes the app just doesn’t feel as smooth as a native one.

Best for:

• Dashboards like CRMs or analytics tools.
• Admin panels.
• MVPs where you need to move fast.

2. Client-Server Apps

This model uses native or semi-native frontends that talk to backend APIs. You see this a lot with mobile apps and some desktop software.

How it works

The frontend is a compiled app that lives on the user’s device. It handles the UI and some logic, but it still relies on a backend for things like data storage and authentication.

Technologies often used:

• Flutter or React Native for mobile.
• Electron or Tauri for desktop.
• Native languages like Java, C++, or Python.

The trade-offs

These apps usually feel faster and more responsive. You also get full access to things like the camera or the local filesystem. They can handle offline work better if you design them that way.

The downside is that they are more complex. You have to manage multiple platforms and deal with app store approvals. You also end up with version fragmentation where some users are on old versions of your app while others are on the new one.

Best for:

• Productivity tools like note apps or IDEs.
• Apps that use a lot of video or images.
• Enterprise tools that need to work closely with the operating system.

3. Local-First SaaS

Local-first software is a newer approach that tries to give you the best of both worlds. It feels like a local app but has the collaboration features of the cloud.

How it works

The data lives on the user’s device first. There is a sync engine running in the background that pushes changes to the cloud when there is a connection.

People usually use:

• CRDTs for merging changes without conflicts.
• Operational transforms for real-time editing.
• Sync queues to manage data flow.

The trade-offs

The biggest plus is that it works offline by default and is extremely fast because there is no network lag. It is also very reliable since the app keeps working even if the server goes down.

However, building a sync engine is a massive engineering challenge. You have to deal with complex conflict resolution and manage more data on the user’s device. It can also be harder to keep everything secure.

Best for:

• Collaborative tools like Notion or Figma.
• Note-taking apps.
• Apps for people working in places with bad internet.

Final Thoughts

The right choice depends on what you are building. If you want to move fast, stick with the web. If you need a high-performance experience, go with a client-server model. If you are building something that needs to be fast and work everywhere, look into local-first.
