Supabase Alternative
The Database AI Agents
Provision Themselves
Supabase is great for apps. ZeroDB is built for AI agents — with zero-auth provisioning, persistent memory, and 69+ MCP tools out of the box.
Why AI Teams Switch from Supabase
Supabase is an excellent app database. But when your AI agents need to provision their own storage, remember conversations, and discover tools via MCP — you need infrastructure designed for agents, not humans.
Zero-Auth Agent Provisioning
Agents provision databases, namespaces, and API keys via MCP or REST — no OAuth, no browser, no human in the loop. Supabase requires human OAuth to create projects.
Built for Agent Memory
Multi-tier memory (working, episodic, semantic), temporal recall, and automatic consolidation. Supabase gives you raw SQL — you build the memory layer yourself.
69+ MCP Tools vs 28
2.5x more MCP tools, focused on agent workflows: vectors, memory, graph, calendar, email, CRM. Supabase MCP is database-admin focused (migrations, SQL).
Vector + Graph in One API
Hybrid vector search with knowledge graph traversal (GraphRAG). Supabase has pgvector but no graph layer — you need a separate graph database.
Agent Discoverability
ZeroDB publishes .well-known/mcp.json and agent.json. Agents find us automatically. Supabase returns 404 on both discovery endpoints.
Sub-2s Time to First Query
Sign up → API key → first query in under 2 seconds. No project creation wizard, no region selection, no waiting for database initialization.

Get Started in 60 Seconds
Install the CLI, get an API key, and start storing agent memory.
# Install the CLI
pip install zerodb-cli
# Initialize and get your API key
zerodb init
# Store your first memory
zerodb memory store "The user prefers dark mode"
# Recall memories semantically
zerodb memory recall "What are the user's preferences?"
