Overzicht

Rig is an open-source Rust library designed to help developers build applications powered by large language models. It provides unified abstractions over multiple LLM providers, embeddings, and vector stores, letting Rust engineers integrate AI capabilities without juggling provider-specific SDKs. The framework focuses on ergonomic, type-safe APIs for common patterns like completions, chat, RAG pipelines, and agent workflows. Because it's written in Rust, it appeals to teams that need performance, memory safety, and reliable concurrency in production AI services. Rig is suited for backend developers, infrastructure teams, and Rust shops looking to ship LLM features without leaving their preferred language ecosystem.

Use cases

Build production LLM services in Rust

Backend teams can integrate LLM completions and chat into high-performance Rust services with type-safe, async APIs and memory safety guarantees.

Implement RAG pipelines

Use Rig's embeddings and vector store integrations to construct retrieval-augmented generation pipelines for search, Q&A, or knowledge-base assistants.

Swap between LLM providers seamlessly

Leverage unified client abstractions to switch or combine multiple LLM providers without rewriting provider-specific SDK code.

Develop AI agents with tool calling

Use Rig's agent and tool-calling primitives to build autonomous workflows that invoke external tools and APIs from a Rust application.

Solid for our team

We rolled this out across the team last quarter and built-in support for RAG and vector stores. RAG pipeline building blocks fits neatly into how we already work, and agent and tool-calling primitives removed a step we used to do by hand. but it has held up under daily use.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on open-source Rust crate, and built-in support for RAG and vector stores caught me off guard. Steeper learning curve for non-Rust developers is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Compared a few options

Evaluated this against two competitors. Where it wins: embeddings and vector store integrations and open source and extensible. Where it lags: steeper learning curve for non-Rust developers. On balance the feature set — especially embeddings and vector store integrations — justifies the 4 stars for our use case.

Years in this space

I've evaluated a lot of these over the years. What stands out here is multi-provider LLM client abstractions — handled better than most — and open source and extensible. Smaller community than Python AI frameworks is my one real gripe. Worth the time if this is your use case.
