The Best GitHub Copilot Alternative
GitHub Copilot is great for inline completions. But what if you want full AI agents like Claude Code or Codex? 1DevTool is the multi-agent alternative that doesn't lock you to one AI.
Why Look for a GitHub Copilot Alternative?
Locked to one AI model
Copilot only uses OpenAI/Microsoft models. What if Claude or other models work better for your task?
Monthly subscription adds up
$19/month for individuals, $39/month for business. That's $228-468/year per seat.
Inline completions only
Copilot suggests code snippets. It can't run autonomous tasks, debug across files, or architect solutions.
