FLXBL Documentation

FLXBL is a graph-based Backend-as-a-Service for teams building multi-tenant applications with evolving schemas and relationship-heavy data. Define entities and relationships once, then use generated REST, GraphQL, TypeScript SDK, and CLI workflows without writing backend CRUD code.

Start Here

Quick Start

Install the CLI, authenticate, inspect context, generate a client, and query data.

FLXBL CLI

The complete command reference for schemas, data, APIs, auth, webhooks, and code generation.

LLM-Friendly CLI

Use JSON output, stdin payloads, dry-run previews, context bootstrap, and stable exit codes from agent loops.

llms.txt

A curated agent-readable map of the canonical FLXBL docs.

Install The CLI

The CLI is the default developer interface for local projects, CI jobs, and coding agents. It can authenticate, inspect tenant context, validate schemas, generate typed clients, query data, and preview mutations before sending them. 

npm install -D @flxbl-dev/cli

# Opens browser-based login through FLXBL Platform
flxbl login
flxbl doctor
flxbl context --json
flxbl generate

Build With FLXBL

Schema Design

Schema JSON, supported relationship cardinalities, generated REST/GraphQL surfaces, validation, and cascade boundaries.

TypeScript SDK

Use the generated TypeScript client with typed collection helpers.

API Reference

Generated REST and GraphQL endpoints, relationship routes, batch operations, vector search, and file APIs.

GraphQL

Generated query fields, relationship arguments, cursor pagination, vector search, and batch mutations.

GraphQL Subscriptions

Stream live entity lifecycle events to WebSocket clients.

Query DSL

Filter, sort, paginate, and traverse graph relationships with JSON.

Architecture

FLXBL splits responsibilities across a PostgreSQL control plane, Neo4j data plane, and Redis infrastructure layer. That makes it a strong fit for tenants with evolving schemas and relationship-heavy workloads, while still exposing generated REST and GraphQL APIs to ordinary applications.
