# Open Source Source: https://0.0.0.0:8080/open-source --- Open Source # We build _in public._ The platform sits on top of an open-source Go ecosystem — langrails, memoryrails, mediarails, guardrails — that you can use on its own, without a PromptRails account. Plus client SDKs, an n8n integration, and the surrounding tooling. Flagship ## langrails Unified Go interface for 24 LLM providers — chains, tools, streaming, retries, prompts, MCP.
