Catalyst by Zoho is a full-stack, agent-ready cloud platform that brings together backend and platform services so teams can ship apps, microservices, integrations, UIs, dashboards, and AI-powered features from a single environment. Students can use it at no cost. The stack spans Compute, Storage (Stratus Object Storage, Relational Data Store, File Store, Cache), Hosting (Slate, AppSail), Intelligence (QuickML/AutoML, OCR, Object Detection, Face Analytics, Image Moderation, Barcode Scanning, Text Analytics), Automation (SmartBrowz, Pipelines CI/CD), and Platform capabilities (API Gateway, Auth, Mail, Push, Search, APM, Logging, Mobile Analytics, Domain Mapping, Security, Testing). For AI agents, it enforces scoped logins, blocks destructive commands in non-interactive sessions, and maintains complete audit logs across application, platform, and MCP tool calls, while supporting isolated environments and granular collaborator permissions. The pricing model includes a permanent $0 free tier with recurring monthly credits, a $250 credit bonus for the first 6 months after signup, and pay-as-you-go rates once free allowances are exceeded.
