In brief
Zoho Catalyst is Zoho's serverless pro-code development platform, with built-in Zia AI services (OCR, NLP, vision, prediction, generation) and European hosting. It lets you build custom applications, microservices and APIs without managing infrastructure. Djtal, the operational AI specialist for Swiss companies, has taken seven applications into production on Catalyst since 2021, among the first deployments in Switzerland.
Why Catalyst
Catalyst started out as a serverless platform. Zoho has since built its Zia AI services into it, so AI is part of the platform's foundation. For a company that wants a custom application without assembling its own AI infrastructure or depending on the large American cloud providers, the balance tips towards Catalyst.
01 · Zia, native AI
Zoho's AI services (OCR, text classification, vision, prediction with AutoML, generation with ConvoKraft) are available directly from Catalyst code. The keys and the AI infrastructure are included in the platform you already pay for. There is nothing to assemble.
02 · European sovereignty
European data centres (Amsterdam, Dublin), with ISO/IEC 27001 and SOC 2 certifications. Your data stays within Europe, which matters to a Swiss company when its own customers ask where their data is held.
03 · Integrated, or independent
Catalyst connects natively to Zoho CRM, Creator, Books and Desk, but it can also be used on its own, as a modern PaaS. You no longer need the usual stack of AWS, Vercel, an AI provider and a DevOps team.
Catalyst vs assembling it yourself
A custom AI application can be built by assembling a cloud provider, an AI service and an orchestration layer. Catalyst brings these pieces together. The table compares them criterion by criterion.
| Criterion | Zoho Catalyst | Assembled cloud stack (AWS Lambda + AI + DevOps) |
|---|---|---|
| Built-in AI | Native Zia services (OCR, NLP, vision, prediction) included | Connected separately, with your own keys, billing and integration |
| Hosting | Europe (Amsterdam, Dublin) · ISO 27001 · SOC 2 | Often outside the EU by default unless you configure the region |
| Infrastructure | Serverless, with no DevOps overhead | Assembly and operation are your responsibility |
| Business integration | Native integration with the Zoho ecosystem (CRM, Books, Desk…) | Connectors you build yourself |
| When to prefer the alternative | A very broad cloud ecosystem, a DevOps team already in place, specific hyperscale needs |
Djtal recommends Catalyst when native AI, European hosting and serverless operation count for your project. When your situation calls for it, we point you to another route.
Catalyst at Djtal
We have worked on Catalyst since its first versions. Some of our internal tools depend on it as well. Here are some of the applications in active production.
Fédération romande des consommateurs · consumer federation for French-speaking Switzerland
Several Creator and Catalyst applications are in use, including a fast search for member services and comparative-testing management built into its website for professionals.
Book distribution and publishing
A secure B2B portal and extended customer service, where AI assists with the first-pass analysis and categorisation of tickets.
Catalyst is one of the two building blocks of our custom AI applications service, alongside Zoho Creator. It is part of our wider expertise in Zoho One. When a process needs to run continuously, the application gives way to a supervised AI agent.
Frequently asked questions
Zoho Catalyst is Zoho's serverless pro-code development platform, with the Zia AI services built in (OCR, NLP, vision, prediction, generation). It lets you build custom applications, microservices and APIs without managing infrastructure. It integrates natively with the Zoho ecosystem or runs on its own.
Yes. Zoho Catalyst runs on European data centres (Amsterdam and Dublin), with ISO/IEC 27001 and SOC 2 certifications. For a Swiss company subject to data protection rules, this means its data and processing stay within Europe.
Zoho Creator is a low-code platform for quickly building business applications based on forms, workflows and reports. Zoho Catalyst is pro-code and is built for fully custom development, such as complex logic, APIs, microservices and operational AI. The two are often combined in a single project.
Zoho Catalyst includes native Zia AI, European hosting and Zoho integration with no DevOps, a clear time saving when those strengths matter. AWS Lambda has the edge when you need a very broad cloud ecosystem or hyperscale capacity, especially if a DevOps team is already in place. Djtal recommends one or the other depending on your context.
No. Zoho Catalyst integrates natively with Zoho One when you use it, but it also runs entirely independently, as a modern PaaS. You can adopt it for a specific need without migrating all your IT systems.
Yes. Djtal has been developing on Catalyst since 2021, from the first versions of the platform, and has taken seven applications into production, among the first deployments in Switzerland. We know the strengths of the platform as well as its pitfalls, which is why we compare Catalyst with AWS Lambda criterion by criterion.
