Optimizely vs. Contentstack

Stop stitching, start shipping.

Contentstack keeps teams waiting. We keep them moving.

Why teams switch

What Contentstack customers keep running into

Dev dependencies

Marketers wait on developers for changes that should take minutes — every publish becomes a ticket. 

Franken-stack upkeep

Managing a DIY tech stack means teams spend time maintaining integrations instead of improving the experience.

Nascent AI

AI features are early stage, leaving teams stuck with manual work while waiting for more features to arrive. 

Get more output from the team you already have

Marketing teams move at their own pace

Publish pages, run campaigns, and personalize — all on the same platform, no dev needed. Visual Builder and embedded agents let your team ship content without filing a ticket.

A platform that earns its keep over time

Optimizely is built to scale as you do. With 500+ releases last year based on real customer feedback, you get more out of the tools you have instead of burning time maintaining connections between them.

AI teammates that work while you sleep

Virtual Teammates don't wait for a prompt. They're hired to execute 24/7 as part of your marketing team — collaborating on tasks, joining meetings, and getting sharper on your preferences with each project they touch.

Optimizely is an ideal tool for us as it provided an easy-to-use platform for content authors while allowing developers to focus on integrations and add-ons rather than constant customization.

TrustRadius Review
From a developer standpoint, having heard tales of how long other CMS frameworks take for initial setup and configuration, Optimizely CMS is the easiest framework to work with. Code setup is quick and easy, documentation is abundant, support is amazing and responsive.

We went from an online brochure to a mobile-driven, data-driven immersive platform… If I was being asked to recommend Optimizely, I wouldn't have a hesitation. The technology backing the project was flawless.
