Sidekick is an agentic CLI-based AI tool inspired by Claude Code, Copilot, Windsurf and Cursor. It's meant to be an open source alternative to these tools, providing a similar experience but with the flexibility of using different LLM providers while keeping the agentic workflow.<p>It was a pet project that turned into a thing been a ton of fun to work on though and looking forward to exploring other ideas. Still in beta, so a few quirks but mostly works.
