What Is Celtra? How Celtra Inc Positions Its Platform

Celtra Inc is an enterprise creative automation platform focused on the full lifecycle of digital advertising creative:

• Production (templates, dynamic creatives, collaboration)

• Activation (ad serving, trafficking tags)

• Measurement (detailed impression and engagement metrics)

Celtra describes two main product lanes:[^celtra-solutions]

• Creative Automation – for scaling digital ad production across markets and channels

• Creative Enablement – for media owners/operators and publishers

Celtra reports that enterprise customers use the platform to scale complex campaigns:

• McDonald’s Nordics: Celtra claims 12.8x greater production efficiency and 0.6 minutes per creative.[^celtra-mcd]

• Spotify: Celtra reports 14,000+ on-brand creatives across 111 markets.[^celtra-spotify]

• Siemens: Celtra cites 13,000+ creatives at 8.2x greater productivity.[^celtra-siemens]

• Wolt: Celtra claims 20x higher output across 30+ countries.[^celtra-wolt]

These are vendor-sourced numbers, but they indicate Celtra’s intended fit: large, distributed teams producing multi-market campaigns at scale.

Celtra’s Core Feature Set for Ad Production

Based on Celtra’s solution pages and documentation, Celtra emphasizes:[^celtra-solutions][^celtra-support]

• Template-based creative automation (Toolkits)

  • Creative teams build governed toolkits/templates.

  • Marketers/local teams customize within brand rules.

• Rich media & dynamic creatives

  • Support for rich media formats, video, and dynamic content.

• Built-in ad serving & trafficking tags

  • Generate ad tags for placement in ad servers and DSPs.

• Tracking & integration

  • Celtra reports 100+ integrations and 100+ standard industry metrics, including Google Campaign Manager 360 (CM360), Display & Video 360 (DV360), IAS, DoubleVerify, Comscore.[^celtra-integrations]

• AI across the creative lifecycle

  • AI-assisted automation for creative variations, performance insights, and workflows (per its 2026 Creative Automation vision).[^celtra-vision]

In short, Celtra is not just a design editor; it is closer to a creative ad-tech platform.

What Is Viewst? How Viewst Positions Its Platform

Viewst is positioned much more narrowly as an HTML5-native ad production studio.

Where Celtra stretches from production through serving and measurement, Viewst defines itself as the infrastructure layer between design (Figma/Adobe) and media (ad servers, DSPs).[^viewst-platform]

Viewst’s core promise: take on the mechanical work of banner production so designers can stay designers.

Vendor claims from Viewst’s website include:[^viewst-marketers][^viewst-digicust][^viewst-betway]

• Teams can save 65 hours per month on creative production.

• A Digicust case study reports 571% CTR growth and +80% leads.

• A Betway case study reports 15,500 hours saved on banner production.

These figures are vendor-sourced but point to Viewst’s focus on production throughput and operational relief, not media execution.

Viewst’s Core HTML5 Ad Production Features

Viewst’s platform highlights:[^viewst-home][^viewst-platform][^viewst-help-status]

• AI Smart Resize – generate all required HTML5 sizes from one master asset.

• AI Image Deflatening – turn flat assets into editable layouts.

• AI Designer – prompt to structured HTML5 banners.

• AI Instant Animator – one-click motion across layers.

• True WYSIWYG HTML5 editor – what you see in the editor is the actual HTML5 output.

• Brandbooks & governance – locked typography, color, and components that propagate across sizes and sets.

• Imports – Figma and Adobe import flows, treating the master creative as the single source of truth.

• Collaboration inside production – statuses, deadlines, comments, and approvals live directly in the banner set.[^viewst-help-status]

• Exports – native HTML5, GIF, and MP4 exports ready for ad servers and DSPs.[^viewst-home]

Viewst explicitly frames this work as “creative infrastructure”, not a replacement for Figma or your ad server.

Celtra Template Model vs Viewst Master-Creative Model

Both platforms try to solve the same underlying problem: repeating yourself less when generating many ad variants.

They approach it differently.

Celtra Template Model (Toolkits)

Celtra’s Toolkits approach is built around governed templates:[^celtra-toolkits]

• Creative teams define layouts, rules, and brand elements once.

• Local marketers or channel teams then activate those templates, updating copy, offers, or images within defined constraints.

• This supports multi-market localization and non-designer activation while maintaining a central brand system.

Functionally, it’s a brand system + activation model: brand governance with marketer self-service.

Viewst Master-Creative Model

Viewst’s model is master-first and designer-centric:[^viewst-platform]

• You create or import a single master HTML5 creative.

• Viewst’s AI Smart Resize generates all needed sizes and keeps them structurally linked.

• Brandbooks enforce color/typography across sets.

• Updates to the master can propagate across the entire banner set.

This is more “design file + export” than Celtra’s activation-focused model, but with robust automation and governance on top.

In practice:

• Choose Celtra’s template model if you need non-designers across 20+ markets to safely self-serve.

• Choose Viewst’s master-creative model if designers and creative ops own production and need extreme speed and consistency on HTML5 output.

Pricing: Celtra’s Bespoke Model vs Viewst’s Transparent Seat Pricing

Celtra Pricing (Bespoke, Volume-Based)

Celtra states that pricing depends on the solution, scale, and serving volume.[^celtra-pricing]

• There is no public price list.

• Expect an enterprise sales process driven by:

  • Number of markets and users

  • Creative volume

  • Ad serving/impression volume

  • Chosen modules (Creative Automation vs Creative Enablement)

If your procurement requires clear rate cards or self-serve sign-up, this can be a consideration.

Viewst Pricing (Transparent as of August 2026)

Viewst publishes per-seat pricing in USD, current as of August 2026 on its site.[^viewst-pricing]

Vendor-listed annual plans include:

• Standard – $110/user/month (USD, billed annually)

  • 3 brandbooks

  • Unlimited HTML5 downloads

  • Entry-level MP4/GIF caps

• Plus – $210/user/month (USD, billed annually)

  • 5 brandbooks per user

  • Unlimited HTML5 downloads

  • Higher MP4/GIF limits

• Premium – $400/user/month (USD, billed annually)

  • 20 brandbooks per user

  • Unlimited HTML5 downloads

  • Highest MP4/GIF limits

• Enterprise – custom pricing

Viewst also offers a free 14-day trial with no credit card required.[^viewst-pricing]

Prices and limits may change; always validate on the current pricing page.

HTML5 & Rich Media: How Celtra and Viewst Compare

HTML5 Ad Production

Celtra

• Supports HTML5 creatives as part of its broader stack.

• Focus is on templates + activation + measurement.

• Well-suited if HTML5 is one of several formats within a global campaign that includes video and rich media.

Viewst

• HTML5-native from the ground up.[^viewst-home]

• Editor = output: the visual you design is the actual code shipped.

• Designed for high-volume banner production with AI-assisted resizes, animation, and versioning.

For teams living in banner production hell (dozens of sizes, markets, and A/B versions), Viewst is the tighter fit.

Rich Media Production (Celtra Dynamic Creatives, Rich Experiences)

Celtra has a long history as a rich media production and serving platform:

• Supports rich media formats (expandables, interactive units) and dynamic creatives, per its solutions and support docs.[^celtra-solutions]

• Connects directly to measurement vendors such as IAS, DoubleVerify, Comscore for viewability, brand safety, and verification.[^celtra-integrations]

• Plays well with premium publisher inventory that often requires specialized formats and certified vendors.

Viewst can export MP4 and GIF, and its HTML5 animations can create sophisticated motion.

However, Viewst does not position itself as a rich media ad server. You would typically:

• Build animating HTML5 banners in Viewst.

• Export ad-network-ready files.

• Upload them to CM360, DV360, or another ad server/DSP for serving and tracking.

If your primary need is rich media production + serving + measurement in one system, Celtra is better aligned.

Tracking Needs: How to Track Celtra Tags (Step-by-Step)

One major difference in Celtra vs Viewst is that Celtra provides ad tags and tracking, while Viewst relies on the ad server or DSP you export to.

Below is a practical guide to tracking Celtra tags in a Google Campaign Manager 360 (CM360) / DV360 workflow, based on Celtra’s integration docs.[^celtra-support]

Note: Always refer to Celtra’s latest support documentation and your ad ops team for exact implementation details.

1) Understand Celtra Tag Types

Common Celtra-generated tags include:

• JavaScript (JS) tags – standard display tags for most web environments.

• iFrame tags – sandboxed tags for environments where JS is restricted.

• Asset tags – direct asset URLs used in some rich media or publisher-specific workflows.

Your choice depends on:

• Publisher specs

• Required tracking and interactivity

• Any restrictions on JavaScript execution

2) Generate Celtra Tags in the Celtra Platform

High-level workflow:

1. Build your creative in Celtra (rich media, HTML5, or video).

2. Configure tracking inside Celtra (click URLs, events, interactions).

3. Go to the publishing/export or ad tags section.

4. Select the target ad server/DSP (e.g., Google Campaign Manager 360).

5. Choose JS or iFrame tags as required.

6. Generate and export the tags.

Celtra’s CM360 integration package often includes macros compatible with CM360/DV360 tracking.[^celtra-support]

3) Implement Celtra Tags in Google Campaign Manager 360

In CM360, a typical setup to track Celtra tags looks like this:

1. Create a placement that matches your buy (site, ad size, dates).

2. Create a new creative in CM360:

   • Type: Third-party or HTML5 / rich media, depending on your configuration.

   • Paste the Celtra JS or iFrame tag into the appropriate field.

3. Attach the creative to the placement.

4. Set click-through URLs as needed (Celtra often passes click tracking via its own tag; align with your tracking strategy).

5. Save and generate serving tags from CM360 for publishers or for trafficking into DV360.

CM360 will then log impressions, clicks, and standard metrics while Celtra captures richer engagement metrics.

4) Add Third-Party Verification Pixels (IAS, DoubleVerify, etc.)

To add verification or viewability tracking (e.g., IAS, DoubleVerify, Comscore) alongside Celtra tags:

1. In CM360, open the creative where you pasted the Celtra tag.

2. Go to the Event tags / Third-party tags section.

3. Add the verification tag URL (e.g., IAS JS pixel or image pixel).

4. Scope it appropriately:

   • Impressions

   • Clicks

   • Viewability (depending on vendor instructions)

5. Test in your QA environment.

Because Celtra reports over 100 integrations and 100+ industry metrics, many verification vendors provide predefined macros or configuration guidance.[^celtra-integrations]

5) Common Tracking & Tag Troubleshooting Tips

When you track Celtra tags in CM360/DV360 or similar platforms, watch for:

• Empty impressions or zero clicks

  • Check that the tag type (JS vs iFrame) is accepted by the publisher.

  • Ensure no ad blocker / network filter is stripping the third-party domain.

• Double counting

  • Make sure you are not counting clicks in both Celtra and CM360 with conflicting redirect chains.

  • Align click-tracking strategy with your ad ops team (decide which platform is source-of-truth for which metrics).

• Macros not resolving

  • Verify CM360/DV360 macros are correctly passed in the Celtra tag.

  • Use network tools (e.g., Chrome DevTools) to inspect fired URLs.

• Creative not rendering

  • Confirm the tag’s size matches the placement size.

  • Test directly in the browser with a minimal HTML page if needed.

How Viewst Fits Into Tracking Workflows

Viewst does not generate ad tags or serve ads.

Instead, your workflow is:

1. Build HTML5 banners in Viewst.

2. Export HTML5/MP4/GIF files.

3. Upload them to your chosen ad server or DSP (CM360, DV360, The Trade Desk, retail media networks, etc.).

4. Configure tracking in that ad server/DSP.

In other words, Viewst plugs into your existing tracking stack, while Celtra provides its own serving + tracking + integrations layer.

FAQ (Schema-Ready Q&A)

What is Celtra?

Celtra is an enterprise creative automation platform used by brands, agencies, and media owners to produce, serve, and measure digital ads across display, rich media, and video.[^celtra-solutions] Celtra combines template-based creative production, ad serving, and integrated tracking with third-party vendors like Google Campaign Manager 360, DV360, IAS, DoubleVerify, and Comscore.[^celtra-integrations]

What is Celtra template model?

Celtra’s template model, often referred to as Toolkits, lets creative teams define governed templates and brand systems once, then enables marketers to create localized variations within strict rules.[^celtra-toolkits] This supports multi-market campaigns where non-designers need to adapt creative without breaking brand standards.

How to track Celtra tags?

To track Celtra tags:

1. Generate JS/iFrame tags from Celtra for your desired ad server (e.g., CM360).[^ celtra-support]

2. Create a creative in CM360 and paste the Celtra tag into the third-party or HTML5 creative field.

3. Attach the creative to placements and generate serving tags.

4. Optionally add third-party verification pixels (IAS, DoubleVerify, Comscore) as event tags in CM360.

5. Test tags in a QA environment to ensure impressions/clicks are recorded both in CM360 and Celtra.

Viewst vs Celtra comparison: which is better for HTML5?

For HTML5 banner production specifically, Viewst is generally a better fit because it is an HTML5-native ad production studio with AI Smart Resize, brandbooks, and production-ready HTML5 exports.[^viewst-home][^viewst-platform] Celtra also supports HTML5, but within a broader creative automation and ad-serving stack. If you need pure production speed and editable HTML5 output, choose Viewst; if you also need rich media, dynamic creatives, and built-in serving/measurement, consider Celtra.

Can Viewst track ads like Celtra?

No. Viewst focuses on production and exports HTML5, GIF, and MP4 files for use in your ad server or DSP.[^viewst-home] It does not provide ad serving or deep tracking. To track Viewst creatives, you configure reporting and verification in platforms such as Google Campaign Manager 360, DV360, or other ad servers, similar to how you would track any third-party HTML5 creative.
