Inspect SaaS CMS Packages Without Losing Your Sanity (Package Explorer Update)

Optimizely export packages have quietly become more complex. Inline (nested) blocks in CMS 12 and PaaS solutions weren’t always displayed clearly, and with SaaS CMS—and soon CMS 13—Visual Builder introduces compositions, layout hierarchies, and display templates on top. This update to the Optimizely Package Explorer improves support across these scenarios, making it far easier to inspect and understand what’s actually inside your packages.

Using HeadlessKit to build a head for an Optimizely SaaS CMS in .NET 10

Headless has a tendency to promise freedom and deliver alignment meetings. Two codebases. Two sets of models. Two teams trying very hard not to drift apart. With Optimizely SaaS CMS, headless is mandatory. So instead of fighting it, I decided to flip it. What happens if we build the head first — properly, in .NET — and let the CMS adapt to that reality? That experiment became CodeArt.Optimizely.HeadlessKit - now available as open source.

Opalytics Under the Hood – How I wired Piwik PRO into Opal with .NET and JSON

In the previous post , I showed how Opalytics lets you ask human questions and get analytics answers. This time we’re going full dev-mode: OAuth tokens, discovery docs, tool calling—and a small detour where I didn’t use the official SDK and built my own attribute-based version instead.

Adding granular editor access control to built-in parts of Optimizely CMS 12

A classic challenge in Optimizely CMS (well, really in any system I guess), is to ensure that the right people have the right access - and that potentially dangerous actions can't be accidentally done by unqualified users.

Scan file uploads for Malware in EPiServer/Optimizely CMS 11 - EPiServer Forms

Do you have forms on your website where visitors can upload files? Perhaps CV's for job applications or documentation for claims, or other kind of applications or images? And have you thought about the risk of these files potentially containing malware right on your production webserver? A client of mine has this concern on an EPiServer (now Optimizely) CMS 11 using the EPiServer Forms extension and I investigated and found an approach to handle it.

Opensource release: New Package Explorer for Optimizely CMS

The import/export ".episerverdata" packages have been around as far as I can remember - and even though they might seem a bit outdated, it's still one of the most common ways to move content around today. But it can be quite a hassle to work with. I recently was inspired to build a tool that will hopefully make life a bit easier when dealing with the packages across versions.

Tracking UTM Parameters in Optimizely CMS Forms

When you are spending your marketing dollars on social media / CPC campaigns, correctly attributing your leads is everything so you know where to invest more. Usually you can get this insight from your Marketing Automation or analytics - but I recently got a question if it's possible to also automatically add it to your Optimizely CMS forms. And of course it is. Here are two ways of doing that.

[Series: Headless Site on Optimizely Graph] Exploring interesting ways we can query the content

Look up in the sky! It's a bird! No, wait - it's Optimizely Graph! This is part 2 in the blog post series where we explore how a fully functioning headless site can be build in .NET core using Optimizely Graph, and in this post we'll see how Optimizely Graph is both a powerful search & query engine (on par with good old Episerver Find) - but also how it can fully replace the content delivery API.

New Series: Building a .NET Core headless site on Optimizely Graph and SaaS CMS

Welcome to this new multi-post series where you can follow along as I indulge in yet another crazy experiment: Can we make our beloved Alloy site run as a headless site on top of Optimizely Graph (and SaaS CMS) using a mix of both MVC, Razor Pages and Blazor components - and can we make both the developer and editor experience as we are used to in classic Optimizely/Episerver sites? Let's find out!
