What is Sidekick CLI?

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.

Features:

  • No vendor lock-in. Use whichever LLM provider you prefer.
  • MCP support
  • Use /undo when AI breaks things.
  • Easily switch between models in the same session.
  • JIT-style system prompt injection ensures Sidekick doesn't lose the plot.
  • Per-project guide. Adjust Sidekick's behavior to suit your needs.
  • CLI-first design. Ditch the clunky IDE.
  • Cost and token tracking.
  • Per command or per session confirmation skipping.
