# Firebase

Firebase is Google's app-development platform that Cole uses as the backend scaffolding around Google Cloud Functions and as a drop-in authentication provider. In his most-profitable-niche build, the project layout is organized around it: "the general folder structure for Google Cloud functions so you have like your initial U Firebase stuff and then within functions here you have the source" (the-most-profitable-ai-niche, 0:15:11). Firebase supplies the initialization and hosting conventions that wrap the serverless functions serving the agent.

Cole also reaches for Firebase when a project needs authentication without building it from scratch. For a custom Chrome extension he notes you can bolt on identity with a managed provider: "you're also going to have to include authentication for this extension using a tool like Firebase for example" (use-chatgpt-in-two-clicks, 0:20:46). This mirrors how he uses Supabase auth elsewhere, Firebase is the equivalent within the Google Cloud ecosystem for standing up user accounts quickly. It sits on the backend/deployment side of Cole's stack rather than the RAG or vector-store side.

## Realizes

- [Securing Agent APIs](../../concepts/api-security.md) - Protecting agent endpoints and secrets, handled out of the box by Firebase's managed authentication.
- [Agent Deployment](../../concepts/agent-deployment.md) - Getting agents to production and choosing a host, where the Google Cloud Functions plus Firebase structure fits.

## Contrasts with

- [Supabase](./supabase.md) - A single platform providing Postgres plus a pgvector store, Cole's more frequent backend and auth choice outside the Google ecosystem.

## Related

- [Chat Interfaces](../../concepts/chat-interfaces.md) - Wrapping agents in chat surfaces with adapters and durable history, the front ends a Firebase-backed function serves.
- [AI Agent Business Niches](../../concepts/ai-agent-business-niches.md) - Productizing AI agents for concrete business use cases, the context where Cole builds these client-facing backends.
- [Community-Driven Development](../../concepts/community-driven-development.md) - Building products and open source in public with a community and a shared roadmap.
- [Tool Design](../../concepts/tool-design.md) - Designing agent tools to be few, single-purpose, and well-described so the model uses them reliably.
