Difference between Fizzly Code, Kilo Code, Roo Code and Cline
Fizzly Code is based on Kilo Code, which started as a fork of Roo Code, which itself is a fork of Cline. We frequently merge features from these open-source projects and contribute improvements back. Built on these foundations, Fizzly Code is independently developed with our own vision for AI coding agents.
No need to fiddle with API keys, Fizzly Code ships with the latest AI models plugged in, including Gemini 2.5 Pro, Claude 4 Sonnet & Opus, and GPT-5
MCP Server Marketplace: Easily find, and use MCP servers to extend the agent capabilities.
