Comparison
rig vs 12-factor-agents
Verdict
Pick rig if rig is a Rust library designed to create modular and scalable LLM applications with extensive support for agentic workflows, multi-turn streaming, full compatibility with GenAI conventions, and integration capabilities; pick 12-factor-agents if a TypeScript-based framework focused on applying 12-factor principles to build production-ready software with large language models.

Choose rig if…
- rig is primarily Rust; 12-factor-agents is TypeScript.
- License: rig is MIT, 12-factor-agents is Other.
- Self-hosted as a Rust library.
- Pricing: Free to use under MIT license with potential premium support options..
- Tags unique to rig: agent, artificial-intelligence, automation, generative-ai.
- You should use Rig when you need to work with LLM applications in Rust and want full WASM (core library) compatibility.
When NOT to use rig
- Avoid using Rig if you are working on applications that do not require or support Rust as it is specifically built to facilitate LLM operations within a Rust environment.
- Rig may not be suitable if your project cannot handle potential breaking changes, which are expected due to its rapidly evolving nature and upcoming feature updates.
Choose 12-factor-agents if…
- 12-factor-agents is primarily TypeScript; rig is Rust.
- License: 12-factor-agents is Other, rig is MIT.
- Pricing: Free to use with open-source licenses.
- Requirements: Min 4 GB RAM; Requires Docker; Requires a solid understanding of TypeScript and familiarity with concepts like prompt engineering and context window management..
- Tags unique to 12-factor-agents: 12-factor, agents, context-window, framework.
- You are specifically developing AI agents or LLM-powered applications in TypeScript and need a structured guideline grounded in the 12-factor app principles.
When NOT to use 12-factor-agents
- If your project requires languages other than TypeScript or if your application already has a strong foundation not necessarily aligning with the 12-factor app principles.
- When you’re looking for comprehensive deployment automation tools rather than guidance on building LLM-powered agents and ensuring their reliability in production environments.
