Codeium
AI-native coding environment, originally launched as Codeium, that pairs an IDE with an agentic coding assistant called Cascade.
About
Codeium launched as an AI code completion plugin before pivoting to build Windsurf, a full AI-native IDE centered on agentic coding. The editor's Cascade assistant can plan and carry out multi-step development tasks autonomously, navigate large codebases, and handle context across sessions. In late 2025 Windsurf was acquired by Cognition, the company behind the Devin coding agent, and the product has since been integrated into the Devin Desktop platform at devin.ai. The core IDE capabilities remain available, and the free tier continues to give individual developers access to completions and agent features, with Pro and Teams plans available for heavier usage and collaborative workflows.
