Like all products in the AI space today, it's a question of whether what it costs creates that much value each month. While it's not a force-multiplier in the same sense as Claude Code or Codex, I still think Warp is, even at $20, but that's probably pushing it (I've had months where I was able to speed run an unfamiliar workflow with Warp, and other months where I didn't use it for anything that iTerm couldn't handle)
For $20/month, I can buy a Claude Code subscription and have it drive my terminal on autopilot. Tool calling in traditional LLMs might just obsolete Warp's business model.
