Nintex Alternative for SharePoint Server SE: How to Future-Proof Your Workflows

Stop rebuilding your SharePoint solutions every few years.

If you're still running Nintex workflows or InfoPath forms, you're sitting on ticking time bombs.

‍

Support is ending. For all of them - Nintex on-prem and InfoPath forms. Migration paths are unclear. And worst of all?
Most alternatives force you to start from scratch — again.

‍

But what if you could modernize your SharePoint Server environment without rebuilding everything and still stay fully future-proof? That’s exactly what this guide (and the live demo behind it) shows.

‍

‍

Why You Need a Nintex Alternative on SharePoint Server

If you're still running Nintex workflows or InfoPath forms on your SharePoint Server, you're not just dealing with outdated tools. You're operating on borrowed time.

‍

For many organizations, these technologies have been the backbone of critical business processes for years. Approval workflows, contract management, data collection — everything just “works.” And that’s exactly the problem.‍

‍

InfoPath has reached its end of life.‍

Support deadlines have already passed or are dangerously close, depending on your setup. That means no updates, no fixes, no security guarantees. What once felt stable is now a growing risk with every passing day.

‍

Nintex workflows are built on legacy workflow engines

At the same time, Nintex workflows are built on the 2010 engine. This is no longer supported and is slowly becoming incompatible with modern SharePoint environments.

‍

And here’s where it gets uncomfortable:

Migrating to modern online systems from Nintex involves significant additional costs. However, there is no automated migration path. This means you will have to pay a great deal more and still rebuild all your processes from scratch.

‍

This is why choosing a true Nintex alternative for SharePoint Server is no longer a technical decision — it’s a strategic one.

‍

You’re deciding whether you want to keep rebuilding or finally move to something that lasts.

‍

A Modern Nintex Alternative for SharePoint Server

If you look at most “Nintex alternatives,” they all follow the same pattern: They replace one tool with another tool.

‍

Different interface, different vendor — but fundamentally the same problem: You’re still building on something that may not survive the next platform shift.

‍

What makes skybow fundamentally different is that it doesn’t try to replace Nintex feature-by-feature. Instead, it changes the way you build solutions on SharePoint altogether. And that’s where the real advantage lies.

‍

Built for Both SharePoint Server and Microsoft 365

‍

One of the biggest challenges companies face today is this: “We are on-premises now. But we might move to Microsoft 365 later.”

‍

Most tools force you to choose:

• Either optimize for on-prem
• Or rebuild everything for the cloud later

‍

With skybow, this decision disappears. You build your solution once — and it works in both worlds:

• SharePoint Server SE & 2019 (on-premises)
• Microsoft 365 / SharePoint Online

‍

That means: No migration projects. No rebuilding workflows. No rewriting forms. Because here, SharePoint remains the center of your solution, not just a data source.

‍

Two Practical Approaches for Replacing Nintex & InfoPath on SharePoint Sever: How It Works in Real Life

Instead of forcing a one-size-fits-all approach, the skybow platform gives you two clearly separated ways of working. And this is where it becomes extremely practical.

‍

1. skybow Studio — For Real Business Solutions on SharePoint Server

Think of this as your enterprise-grade replacement for Nintex and InfoPath. In order to replace Nintex and InfoPath, you're able to build everything you need in your SharePoint Server SE solution in one single plattform - the skybow Studio. There you are able to replace everything you have now in your Nintex workflows or InfoPath forms:

• Forms
• Business logic (workflows, actions)
• Lists & libraries
• Permissions
• UI structure

‍

Then you package it and deploy it to SharePoint Server SE, SharePoint 2019 or SharePoint online. You can even run your soltions in hybrid environments.

‍

As soon as your SharePoint solution is live you have great Application Lifecycle Management capabilities in skybow Studio. You can for example

• Version your solution (e.g., v1.9 → v1.10)
• Deploy to test and production environments separately
• Update systems with a controlled release process

‍

Compare this to Nintex, InfoPath or other replacement options like Power Platform. If something changes in your solutions on those platforms, you often modify things directly in production.

‍

With skybow Studio you move from “configuration chaos” to real software development practices.

‍

‍

2. skybow Add-ins for SharePoint Server to Replace Nintex and InfoPath

Now here’s the second approach — and this is where things get really practical.

Because not every business requirement needs a full SharePoint business solution and not every change needs a full application lifecycle.

‍

Sometimes, you just need some enhancements to you out-of-the-box SharePoint Server SE setup - things like:

• Add a field
• Create a reminder
• Automate a small process

‍

And you need it fast.

That’s where Add-ins come in. They work directly inside your SharePoint Server or online environment — no separate environment, no packaging. And that’s a huge usability advantage.

‍

‍

Example 1: Deadline Reminder in SharePoint

‍

A very common real-world requirement: “Send me an email when a contract deadline is today.”

‍

With Add-ins:

• You define a filter: deadline = today
• Schedule a daily check (e.g., 6:00 AM)
• Configure an email action

‍

Done. No workflow engine. No external service. No complexity.

‍

‍

Example 2: Auto-assign Manager in SharePoint

‍

Another classic: “When I select a department, automatically fill in the manager.”

‍

Instead of writing code and maintaining lookup logic manually you simply:

• Define a lookup
• Inherit the value

‍

The field fills automatically even without showing it in the form to the enduser.

‍

‍

Example 3: Triggered Automation in SharePoint

When an item is created:

• Create another item in a different list
• Update permissions
• Notify users

‍

These are things that are not possible client-side in standard SharePoint. But with the skybow background services, they run:

• On the server
• With proper permissions
• Fully automated

‍

‍

skybow Studio vs skybow Add-ins for SharePoint Server and Online: When to Use What for Replacing Nintex or InfoPath

• Complex business apps ➡️ skybow Studio
• Enterprise-grade workflows ➡️ skybow Studio
• Quick automation ➡️ Add-ins
• Power user customization ➡️ Add-ins

‍

👉 Best practice (from real customers):
Use a combination of both — but never on the same site to avoid conflicts.

‍

With this approach, you:

✅ Eliminate dependency on legacy workflow engines
✅ Avoid repeated rebuild cycles
✅ Keep flexibility for cloud migration
✅ Empower both IT and business users

‍

‍

Ready for a Future-Proof Nintex Alternative?

Unlike traditional replacements, skybow doesn’t just swap one legacy tool for another. It gives you a way to build SharePoint solutions that are sustainable, scalable, and ready for both SharePoint Server SE and Microsoft 365 — without constant rebuilding.

‍

If you want to move away from outdated workflows and finally take control of your SharePoint architecture, now is the time to act.
