On April 28, 2026, Warp open-sourced its terminal client under AGPL-3.0, picked up 60,000 GitHub stars, and declared itself an "agentic development environment." OpenAI signed on as founding sponsor. The announcement looked like a triumph of developer-first idealism.
Read the fine print and a different picture emerges: the terminal is free; the product that matters — Oz, Warp's cloud agent orchestration platform — remains fully proprietary. Warp is not becoming an open-source project. It is becoming an enterprise SaaS company with an open-source frontend.
None of that is inherently bad. But it is what this review is actually about: does the $20/month Build plan deliver enough AI value to justify adding Warp to a stack that probably already includes Cursor or Claude Code?
