CrewAI Multi‑Agent SaaS Boilerplate with FastAPI, React Dashboard & Docker

Stop wasting weekends wiring agents together. Start launching multi‑agent AI features the same day you build them.

You try to test a new CrewAI workflow, but you’re stuck stitching FastAPI routes, fixing Docker networking, bolting on auth, and hacking together a dashboard just to see a single agent run. You watch entire days disappear to boilerplate instead of validating your idea. You know exactly what you want to build — but the infrastructure keeps getting in the way.

This boilerplate gives you a complete, production‑ready multi‑agent SaaS foundation built on FastAPI, React, Docker, and CrewAI. It includes 12 fully configured backend services, 9 FastAPI routes for tasks and history, a real pgvector persistence layer, a secure multi‑tenant auth flow, and a real‑time React dashboard wired to agent runtimes. Install dependencies, run one Docker command, and ship workflows in under 30 minutes.

What's Included:
- FastAPI backend with 9 ready-to-run agent task, history, and billing routes
- Pre‑built CrewAI workflow folder with 6 modular agent patterns
- JWT auth service with 8 hardened middleware checks
- pgvector database service file with memory, embeddings, and run‑logging tables
- Docker compose stack with 14 environment‑safe configurations for backend, frontend, and embeddings
- Rate‑limiting and tenant‑scoping utilities to prevent cross‑account access
- React dashboard with polling hooks for real‑time agent output
- Developer CLI for seeding users, resetting agents, and clearing vector stores
- Webhook verifier with HMAC signing patterns

Built from patterns used to deploy paid multi‑agent features inside real SaaS products serving thousands of monthly users, including hard lessons from debugging Dockerized agent pipelines in production. Every component exists because it solved a failure mode that cost hours — or days — to fix.

Who This Is For:
- Solo founders validating multi‑agent features without hiring backend help
- Indie hackers building AI tools who need a reliable auth + billing‑ready stack
- Engineers integrating CrewAI into an existing product without slowing roadmap velocity

Who This Is NOT For:
- Anyone looking for a no‑code setup
- Teams wanting a fully hosted or subscription platform instead of source code

Guarantee: If this doesn’t save you at least 8 hours of setup and debugging, reach out for a full refund.
