What's New in ArcGIS Web Editor (February 2026)

ArcGIS Web Editor is a web-based editing app that provides a focused, efficient experience for maintaining authoritative GIS data, whether you’re editing feature geometry on a map or updating attributes in a table. This February 2026 update for ArcGIS Web Editor in ArcGIS Online introduces improvements that help teams edit with more confidence and streamline how editing tools are delivered to different audiences.

Let’s take a closer look at what’s new in the February update.

What’s New

Draw and edit true curves for cleaner, more accurate geometry

This release adds support for drawing and editing true curves, making it easier to create smooth, true-to-form geometry when your data requires it. Previously, curved shapes often had to be represented as many small straight segments (densified geometry). Now, you can draw and maintain curves as curves, so features stay closer to the shape you intended, even for future edits.

What this enables

• Create features that include both straight segments and curved segments in a single geometry, without resorting to “many tiny lines” to approximate an arc.
• Preserve curved geometry when editing existing features that already contain curves, instead of breaking the shape into straight segments.

Example: When digitizing a cul-de-sac, you can sketch the straight approach, add the curved arc, and finish with another straight segment, resulting in cleaner geometry that better represents the real-world feature.

Web Editor Instant App Template Is Now Generally Available

The Web Editor Instant App template has moved out of beta and is now generally available with the February ArcGIS Online update. This gives organizations a supported way to deploy a focused editing experience built on ArcGIS Web Editor, especially when different teams need different toolsets.

With the template, you can configure an editing experience that helps users stay on task by tailoring what they see and what they can do. For example, you can:

• Provide editors with only the tools they need for a specific workflow
• Reduce complexity for occasional or non-GIS editors
• Support consistent editing by guiding users through a streamlined interface

Whether your team is maintaining asset records, updating inspection tables, or performing data stewardship across departments, the template helps you deliver the right editing tools to the right users, without overwhelming them.

Conclusion

The February 2026 update strengthens ArcGIS Web Editor as a modern web editing experience by improving how curved geometry can be created and maintained and by expanding supported options for deploying focused editing apps through Instant Apps. We’re excited to keep building on this momentum in upcoming releases.

We look forward to sharing more enhancements in upcoming releases — stay tuned!
