FAQs

Catalyst by Zoho is an agent-ready full stack cloud platform equipped with front-end, back-end and AI/ML services allowing users to build full-stack applications in one unified platform.

Supabase is a PostgreSQL-first back-end platform that provides built-in authentication, real-time APIs, storage, edge functions, and database management for modern applications.

Yes. Supabase offers a free tier with limits on database size, functions, bandwidth, and project activity. Free projects may be paused after prolonged inactivity.

Supabase uses subscription-based pricing with Free, Pro, Team, and Enterprise plans. Costs can increase with higher usage of compute, storage, bandwidth, real-time connections, and edge functions.

Egress refers to data transferred out of a platform to users, applications, or external services. Many cloud providers charge egress fees when bandwidth usage exceeds included limits. Catalyst doesn't charge any such fees.

Railway hosting is best suited for containerized applications, back-end APIs, prototypes, internal tools, and developer workflows requiring fast deployments with minimal DevOps setup.

Some of the top Supabase alternatives include Catalyst by Zoho, Appwrite, Railway, and Render. Each platform focuses on different strengths, such as open-source back-end infrastructure, full-stack development, containerized deployments, persistent back-end hosting, or long-running back-end workflows.

Catalyst is stronger for back-end orchestration because it combines APIs, event functions, cron jobs, job scheduling, and persistent AppSail services inside one platform.

Railway and Render provide the most infrastructure flexibility because they support full container-based deployments and persistent back-end services.

Catalyst Slate is the go-to platform for front-end developers because it helps developers host their front-ends seamlessly with one-click rollbacks, automatic scaling, and integrated developer workflow.
