About This App
Zoho Catalyst is a full-stack serverless development platform built by Zoho Corporation out of Chennai, India. Launched for public availability in 2021, it provides over 30 scalable cloud services โ serverless functions, relational data store, file storage, caching, API gateway, web hosting, and built-in AI/ML capabilities via Zoho's Zia engine โ all under one roof, designed to let developers build and deploy applications without managing infrastructure. Catalyst supports serverless functions in Java and Node.js, with a built-in AppSail container service for applications that need persistent runtimes. The platform includes out-of-the-box services for authentication, push notifications, search indexing, email, and CRON jobs. The AI/ML stack is a differentiator โ Zia provides OCR, object detection, sentiment analysis, keyword extraction, and LLM access without requiring separate AI service subscriptions. Catalyst also integrates natively with the Zoho ecosystem (CRM, Creator, Desk). Pricing is pure pay-per-use with a generous free tier: 25,000 GB-seconds of function execution, 100,000 API gateway requests, 300,000 web hosting requests, and 100 Zia API calls per month โ all free. The 180-day trial adds extra credits. Paid usage kicks in only when you exceed free limits, with functions at $0.000016/GB-second and storage at $0.02/GB. A $1,000/month minimum applies once you cross the free tier, which positions Catalyst more for serious production apps than hobby projects. Catalyst is best suited for developers already in the Zoho ecosystem who need a serverless backend, and for teams wanting integrated AI/ML without managing separate cloud AI services. Developers who need multi-language support beyond Java/Node.js, or who prefer the broader ecosystem and community of AWS Lambda or Vercel, may find Catalyst limiting. The $1,000/month minimum on paid plans is a steep jump from the free tier.
