r8r is an open-source workflow automation server written in Rust, providing behaviorally compatible functionality with n8n including workflows, credentials, expressions, webhooks, and REST APIs. It supports many node types for triggers, core functions, files and formats, and integrations with services like Slack, Telegram, GitHub, and many AI models. Designed for reliability and performance, it can migrate data from n8n and runs workflows with queue modes using Redis or PostgreSQL.
