mini-rag

Mini-RAG is an open-source educational project that teaches RAG (Retrieval-Augmented Generation) application development through step-by-step tutorials. It demonstrates production-ready patterns using FastAPI, PostgreSQL with pgvector, MongoDB, Celery workers, and LLM integration (OpenAI or local Ollama).

What mini-rag is

A Python-based RAG framework built on FastAPI with pluggable LLM and vector database factories, supporting both MongoDB and PostgreSQL backends, async file processing via Celery, semantic search, and deployment patterns. Includes monitoring via Prometheus/Grafana and task scheduling with Celery Beat.

Quickstart

Get the mini-rag source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/bakrianoo/mini-rag.gitcd mini-rag# follow the project's README for install & configuration

Best use cases

Learning RAG Architecture & Implementation

Step-by-step tutorial structure with branched code checkpoints makes it ideal for engineers learning RAG patterns, LLM integration, and production-ready application design.

Building Custom RAG Applications

Modular factory patterns for LLM and vector DB selection allow rapid prototyping of domain-specific Q&A systems with file ingestion and semantic search pipelines.

Demonstrating Full-Stack GenAI Deployment

Docker Compose setup with FastAPI, Celery, PostgreSQL, monitoring, and flower dashboard shows production deployment patterns for educational or internal projects.

Implementation considerations

  • Requires Python 3.10+, PostgreSQL 13+, and Redis for Celery. Docker Compose provided but assumes Docker/Linux environment familiarity.
  • Vector DB factory supports multiple backends (MongoDB, PostgreSQL pgvector); verify dependency versions and compatibility before production use.
  • LLM factory abstracts OpenAI and Ollama; adding new LLM providers requires implementing the factory interface.
  • Alembic migrations included; database schema evolves across tutorial branches, so migration path must be validated for your target state.
  • Celery workers, beat scheduler, and flower dashboard require separate process/container management; horizontally scaling workers requires Redis or RabbitMQ tuning.

When to avoid it — and what to weigh

  • Requires Commercial LLM Support Without Setup — Integration assumes you provide own API keys (OpenAI, etc.) and configure endpoints. Not a managed service; requires infrastructure management.
  • High-Volume Production with SLA Requirements — Project is educational in scope. Lacks explicit benchmarks, security audit documentation, and enterprise-grade operational tooling (observability, failover, cost controls).
  • Non-English Deployment Teams — Core documentation and videos are in Arabic, which is valuable for that audience but may limit adoption or troubleshooting for teams without Arabic speakers.
  • Proprietary/Non-Disclosure Requirements — Educational nature and public GitHub presence mean modifications or customizations may not align with confidentiality constraints in some enterprises.

Security considerations

Project is educational and does not claim security audit. Key areas requiring review: API key/credential management (env vars in Docker), database access control, Flower dashboard authentication (admin/password), CORS policies, input validation on file uploads, and rate limiting. No mention of secrets encryption at rest or in transit hardening.

Alternatives to consider

LangChain or LlamaIndex

Production-grade libraries with broader LLM ecosystem, chain abstractions, and community integrations. Less educational but more feature-complete for commercial RAG.

Haystack by Deepset

Open-source RAG framework with built-in orchestration, modular pipelines, and enterprise docs. Steeper learning curve but battle-tested for production.

Verba (Weaviate-based RAG)

Lightweight, open-source RAG starter with vector DB bundled. Simpler than mini-rag for quick proof-of-concepts but less tutorial structure.

mini-rag FAQ

Can I use this in production?
Technically yes (Apache-2.0 allows it), but it is an educational project. Lacks security audit, performance benchmarks, and operational documentation. Recommended for internal/non-critical use or as a reference architecture.
Do I need to watch the Arabic videos to use the code?
No. Code is available in branches without videos. However, videos provide context on design decisions. Non-Arabic speakers can follow code branches and READMEs independently.
What LLMs are supported?
OpenAI (via API key) and Ollama (local server). LLM factory pattern makes adding others possible; requires implementing the factory interface.
How do I scale this for higher throughput?
Celery workers can be horizontally scaled via Docker/Kubernetes, but Redis or RabbitMQ broker must be sized accordingly. Database (PostgreSQL) and vector index (pgvector) also become bottlenecks; requires profiling and optimization.
