Celtra Reviews & Product Details

Cross-collaboration across multiple teams and markets is significantly more efficient when working from a shared foundation. Having access to a single creative set that teams can build from creates alignment, reduces duplication of effort, and allows markets to move faster while still tailoring execution to their local needs.

At times, creative weights in Celtra are still not immediately apparent and are often only surfaced during trafficking. That said, there have been improvements. Making creative weight more visible and easier to access earlier in the asset build process would further reduce friction and prevent last-minute adjustments.

I like that Celtra, from a creative and graphic design perspective, includes tools for technical audience like myself. I'm able to generate designs in Celtra that look high quality, almost as if I created them in Adobe apps. I also like how easy it is to share assets with stakeholders using a preview and not needing to export files. I can make changes quickly without having to open a hundred different layers. Automated text resizing and auto layout options function really well. It means that we can create one design file for lots of different content types and lengths.

The user experience with project file management is still a little bit lacking. It's easy to lose projects if you have a lot in the system. Additionally, I would like more options for exporting assets, espcially for non-display/social, like vector. Lastly, setting up a template can be complex, to ensure the auto layout and text resize works correctly. It would be nice if there was an established template library, because at the moment, you're given a blank sheet of white space and you have to build it from scratch.

The intuitiveness for generating automated content and the ease of creating great quality content, the ability to generate so many assets does not sacrifice quality. Review collected by and hosted on G2.com.

When the content feed starts to have more content, the Celtra page crashes, and even if it's not a large file that has problems loading, it ends up deleting/moving content that had already been integrated. Review collected by and hosted on G2.com.

Strong video & rich-media capabilities – Especially for CTV and high-impact display, Celtra handles heavy creatives while still keeping performance in check.

Ad server–agnostic – Creatives work smoothly across platforms like TTD, DV360, Meta, etc., which reduces rework and troubleshooting.

Built-in QA and version control – Makes audits, updates, and fixes much easier, particularly when multiple stakeholders are involved. Review collected by and hosted on G2.com.

Debugging isn’t always intuitive – When something breaks (tracking, click-through, macros), finding the exact root cause can take time.

Preview vs live discrepancies – Creatives may look fine in Celtra preview but behave differently once live in platforms like TTD or on certain publishers.

Overkill for simple creatives – For basic banners or quick turn requests, Celtra can feel like more work than necessary. Review collected by and hosted on G2.com.

The biggest win is the ability to build one master template and instantly generate hundreds of variations. You can swap out copy, images, or CTA buttons across different sizes (300x250, 160x600, etc.) without having to manually redesign each one. It effectively kills the "grunt work" of digital production. Review collected by and hosted on G2.com.

Celtra is built for the "Goliaths"—global brands like Spotify, Adidas, and Unilever.

Cost: The pricing is steep for small-to-mid-sized agencies.

Overkill: If you only need to make five banners for a small local campaign, the setup time and cost of Celtra will feel like using a literal rocket ship to go to the grocery store. Review collected by and hosted on G2.com.

I like the ease of producing and adapting content in Celtra, as well as the way to edit and share it so that, as a client, I can review it and provide feedback to my agency. Review collected by and hosted on G2.com.

Include video production with audio in Celtra, more dynamic transitions, better templates, and customization facilities so that the final result of the adaptations is easier for my agency and, therefore, better results for me as a client. Review collected by and hosted on G2.com.

Being someone who leads projects and teams, I think Celtra is very useful. It's especially helpful when it comes to how mobile rich media works well on phones and tablets. The user interface (UI) is easy to use, which makes working with creative stuff much easier. I really like the customer service they offer; their help and teaching have been very important in making special sets that truly get noticed. Review collected by and hosted on G2.com.

Adding third-party trackers and tags during the build stage can sometimes be harder than needed. The process of making rules and measures for checking creative work usually seems more difficult than it needs to be. Review collected by and hosted on G2.com.

The layout and design options are great. Review collected by and hosted on G2.com.

I wish there were an easier way to animate. I understand that the current way gives you the most flexibility to do what you want but I wish there were a template animation that could be used first and then adjusted to your liking. Review collected by and hosted on G2.com.

I like the fact that Celtra is easy to use, even for those with no design experience. Its effectiveness in delivering campaigns exactly as designed also adds to its undeniable appeal! The platform allows teams of people from different departments and external contributors to all have access to their own creative, making collaboration a breeze. It allows us to create dynamic, engaging ads with interscroller units while keeping our clients entertained - delivering successful results every time. Review collected by and hosted on G2.com.

I dislike the lack of a rapid response team for incidents in Celtra. In addition, the price point is too high and unnecessarily restrictive, leading practitioners to develop their own solutions rather than buy in. This resistance has been exacerbated as vendors like In-Housing have also gained traction in the digital marketing space. Review collected by and hosted on G2.com.
