OzBrain vs Supabase: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of OzBrain and Supabase — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
OzBrain
Monsef Holdings Pty Ltd
A hosted knowledge base every AI agent can read and write, shared across Claude, ChatGPT, Cursor and coding agents via connectors.
Key features
- Connector Setup: Add OzBrain from the connector menu in Claude or ChatGPT, sign in and approve - no code, SDK or installation required.
- Nested Article Retrieval: Knowledge is broken into nested pieces so an agent loads only the slice it needs, cutting tokens, latency and hallucination.
- Automatic Supersession: When newer thinking arrives, OzBrain revisits existing articles, marks the old as replaced and links forward to the current version.
- Staged Writes: Changes are proposed before they land, so multiple agents can write concurrently without clobbering one another.
- Change Ledger: Every edit records the agent, the article and the stated reason, giving a readable history of how the brain reached its current state.
- Shared Team Brains: Point a whole team's agents at one brain so context worked out in one person's chat is immediately available in everyone else's.
- Broad Client Support: Works with Claude, ChatGPT, Claude Code, Cursor, OpenClaw, Hermes Agent, Gemini Spark where available, and any connector-capable client.
- Markdown Export: Export everything as plain markdown at any time, including after cancellation, with deletion meaning the content is actually removed.
Best for
- Cross-Agent Continuity: Stop re-explaining the same project context when moving between Claude, ChatGPT and a coding agent.
- Single Source of Truth: Replace the scatter of launch-plan copies across Drive, Downloads, email and chat with one current version agents read from.
- Team Onboarding: Give a new teammate's agents the accumulated decisions, research and roadmap the rest of the team already has.
- Agent-Maintained Documentation: Let agents append findings and decisions as they work, with humans reviewing and correcting in the same place.
- Rules and Skills Storage: Keep coding standards, conventions and reusable skills where Claude Code and Cursor pick them up automatically.
- Long-Running Research: Accumulate customer research and competitive notes across many sessions instead of losing them to chat history.
Supabase
Supabase
Postgres-first development platform providing hosted Postgres, Auth, instant APIs, Realtime, Functions, Storage and vector embeddings.
Key features
- Hosted Postgres Database: Provides a managed, dedicated PostgreSQL instance with tools and integrations designed for production web, mobile, and AI applications.
- Auto-generated APIs: Instantly exposes REST and GraphQL endpoints from the Postgres schema (PostgREST/Graphile-style auto-APIs) so developers can query and mutate data without writing backend code.
- Authentication and Authorization: Built-in user management, sign-up/sign-in flows, JWT-based auth, and role/row-level security integrations to secure database access.
- Realtime Subscriptions: Change-data-capture based realtime updates and WebSocket subscriptions to push database changes to clients for live features like chat or presence.
- Functions (Edge & Database): Support for serverless Edge Functions alongside Postgres database functions (RPC) to run custom business logic close to data.
- File Storage: Object storage for uploading, serving, and managing files/media with access controls integrated with Supabase Auth.
- Vector Embeddings Toolkit: Integration with pgvector and embedding tooling for semantic search, similarity queries, and AI-driven features.
- Client Libraries & Local Dev: Official SDKs (e.g., supabase-js), dashboard, CLI and local stack tooling (npx supabase start) for rapid development and self-hosting.
- Hosted Postgres database with full SQL/Postgres feature set
- Authentication and Authorization (OAuth, RLS integration with Postgres)
- Auto-generated REST APIs (PostgREST) and GraphQL endpoints
- Realtime subscriptions and broadcasting for database changes
- Database Functions (rpc) and Edge Functions (serverless)
- File Storage for uploading/downloading files
- AI & Vector/Embeddings toolkit (pgvector support and related tooling)
- Official client libraries (supabase-js is an isomorphic JS/TS client)
- Dashboard and management console for projects
- Self-hosting support via supabase CLI (npx supabase start) and Docker
- Open-source codebase (Apache-2.0 for core, MIT for many clients)
Best for
- Full-stack applications: Quickly build web and mobile backends with a managed Postgres database, auto-generated APIs, auth, and storage without building a custom backend.
- Realtime apps: Implement live chat, collaborative editing, dashboards, or presence systems using realtime subscriptions based on Postgres change data capture.
- Authenticated user platforms: Manage sign-ups, logins, roles, and row-level security for multi-tenant or user-specific data access directly integrated with the database.
- File and media handling: Store, serve, and manage user uploads and assets with built-in object storage linked to project auth and permissions.
- Semantic search and AI features: Store vector embeddings in pgvector and run similarity queries for recommendations, semantic search, and retrieval-augmented generation workflows.
- Self-hosted development & testing: Run a full local Supabase stack (CLI npx supabase start) for local development, testing, or self-hosted production deployments.
- Web and mobile backends with Postgres as primary datastore
- Realtime applications (chat, live dashboards) using subscriptions
- Auto-generated APIs for rapid prototyping and production services
- Serverless business logic via Edge Functions and Postgres functions
- File upload, CDN-backed storage and media management
- Vector search and embeddings-powered semantic search or recommendation systems
- Self-hosted local development and CI via supabase CLI and monorepo tooling
