If you are looking at Zakeke, Vectary and Sketchfab alternatives, start with the job you need done, not the tool. This guide gives you a way to compare a platform with a custom build, using one test product and one written register.
Discuss your product rangeTry the demos
Product personalisation, interactive scene publishing and controlling an embedded viewer overlap. They are not the same commercial workflow. So I test each route against the whole requirement, including the data that reaches an order or quote.
This guide does not rank vendors by speed, price or conversion results. It is not a guarantee that any feature, export or integration is included. I describe each provider only at a general level, using the starting point its own documentation shows.
A note on my own view
I led development of the Praxis Digital 3D configurator platform, used by 20+ UK businesses from 2021 to 2025. I now build custom configurators. Because of that, you should weigh my view accordingly. That is why this page gives you a method to run yourself rather than a verdict from me.
Start with the required capability
Many people search for a product configurator software alternative when they really have a narrower question. Do you need customers to personalise a product? Do you need to publish a 3D scene on a page? Or do you need a full buying journey with rules, a saved selection and a quote? The answer changes where you begin.
| Route to investigate | Documented starting point | Question to prove in your project |
|---|---|---|
| Zakeke | Product customisation/configuration tools and integration documentation | Can the required product rules and commercial hand-off be implemented on the proposed plan? |
| Vectary | Publish a shared 3D project and embed it in a supporting website | How will scene interaction connect to your accepted configuration and order data? |
| Sketchfab Viewer API | Embed and control the 3D viewer | Who builds and maintains the surrounding option, rule and commerce application? |
| Custom application | Choose the renderer and build the product workflow | What delivery and maintenance responsibilities will the team own? |
The table identifies where to begin an evaluation, not a guarantee that a particular feature, export or integration is included. Confirm the current plan, terms and supported workflow directly with the provider.
When a platform is likely a good fit
A hosted platform can suit you when the job is close to what the provider documents. These are the signs I look for.
- Your product rules are simple and rarely change.
- Your team has little capacity to maintain code.
- You want to start with a small range and learn from it.
- The provider’s documented workflow already matches your journey.
- You are happy to depend on a supplier for the service and its updates.
A platform can reduce some of the delivery work. It also brings its own service and workflow dependencies. Weigh both sides before you decide.
When a custom build is likely a good fit
A custom build can suit you when your product or process does not sit neatly inside a documented workflow. These are the signs I look for.
- Your rules are complex, or they change often.
- The selection must feed a specific order, quote or ERP record.
- You need full control over how the product looks and behaves.
- You want to own the source and the configuration records.
- You have people who can maintain the build, or you can fund someone who will.
A custom build gives your team more responsibility. That is the trade. See my build or buy guide for the wider decision, and the configurator cost guide for what changes the effort.
Use one sample product across the candidates
Create a small fictional or approved test product. Give it two finishes, one dimensional choice and one dependent component. Supply the same assets and product policy to every candidate. Do not compare a polished template in one tool with an unfinished prototype in another.
The sample should include a conflict that needs explaining, a saved configuration and a defined commercial result. A screenshot of the default model does not show that these tasks work.
An original proof-of-concept register
| Required task | Evidence to request | Acceptance question |
|---|---|---|
| Load the approved asset | Actual delivered file and a target-device review | Do important surfaces and dimensions remain correct? |
| Change an allowed option | Preview, summary and stable option identity | Do all three reflect the same accepted state? |
| Attempt a conflicting choice | A recorded invalid and resolved path | Does the explanation offer a useful next step? |
| Restore a saved selection | A link or record reopened against the current policy | Can an outdated or unknown identity be handled? |
| Confirm commercially | A test cart, quote or specification record | Can fulfilment retrieve the validated selection? |
| Maintain the project | Source/export inventory and responsibility list | What remains usable if the supplier or service changes? |
How to run the proof-of-concept
Run the same steps for every candidate, including a custom build. Keep the evidence in one place so you can compare it later.
- Write down the product rules and the commercial result you need. My project brief can help.
- Prepare one set of approved assets and one product policy. Give the same files to every candidate.
- Load the approved asset on the device your customers will use. Check surfaces and dimensions by eye.
- Change an allowed option. Check that the preview, the summary and the option identity all show the same state.
- Attempt a conflicting choice. Record the invalid path and how it was resolved.
- Save a selection, then reopen it after you change the policy. Note how an outdated or unknown identity is handled.
- Send the selection to a test cart, quote or specification record. Check that fulfilment can read it.
- List the source files, exports and responsibilities. Ask what remains usable if the supplier or service changes.
- Mark each task in the register as passed, failed or not yet demonstrated.
If you want to see how option and rule patterns behave first, explore the working configurator demonstrations. For a look at common journeys, see the configurator examples.
Questions to ask any provider
Ask these of every route, including a custom builder. Write the answers next to each proposal. Do not assume that every candidate works the same way.
Export and portability
- Can I export my source assets, and what am I permitted to do with them?
- Can I export my configuration records and the rules behind them?
- What format are the delivered outputs in, and can I keep them?
How rules are maintained
- Who edits the product rules when the range changes?
- Is that done in an interface, in code or by the supplier?
- How are changes tested before customers see them?
How the order or quote receives data
- What exactly reaches the cart, order or quote?
- Can fulfilment read the validated selection without re-keying it?
- Where does a connection to a system such as an ERP or CRM fit? My system integration guide covers this.
Who supports changes
- Who makes changes after launch, and how are they requested?
- What happens to the project if the supplier or service changes?
Compare the whole cost and ownership
Count setup, asset preparation, catalogue mapping, integration, ongoing service costs and internal maintenance. Ask about the permitted use and portability of source assets, configuration records and delivered outputs. Record the answer alongside the proposal rather than assuming all candidates use the same ownership model.
A custom build gives the team more implementation responsibility. A hosted platform can reduce some of that work while introducing its own service and workflow dependencies. The decision depends on which responsibilities your team can support and what the proof-of-concept actually demonstrates.
Keep the final comparison evidence-based
Mark each required task as passed, failed or not yet demonstrated, with a link to the evidence and the tested version. Do not count a promised feature as a passed test. If loading speed matters, test the same task and assets on the same device and connection.
If you want to talk through a custom route, see my configurator development page, or get in touch.
Frequently asked questions
How do I compare configurator platform alternatives fairly?
Use one sample product and the same assets for every candidate. Run the proof-of-concept register and mark each task as passed, failed or not yet demonstrated. Do not count a promised feature as a passed test.
Should I choose a platform or a custom build?
It depends on your rules, your order process and who will maintain the result. A platform can suit simple, stable needs. A custom build can suit complex rules or a specific order record. I build custom configurators, so weigh my view accordingly and rely on your own test.
What should I ask a provider before I commit?
Ask about export and portability of assets and configuration records, how rules are maintained, how the order or quote receives data, and who supports changes. Confirm the current plan, terms and workflow directly with the provider.
If your store runs on Magento or Adobe Commerce, the Magento configurator guide covers catalogue mapping and the cart hand-off for that platform.
For BigCommerce stores and WordPress-led sites, the BigCommerce and WordPress configurator guide sets out the page, viewer and commerce roles.
