Warp: Pricing, Features & Alternatives

Warp treats each command and its output as a block you can select, share and search, with an editor-style input line instead of a raw prompt. It is now pitched as an agentic development environment: agents in Warp can run commands, edit files and review diffs. The terminal is free on every plan. What you pay for is AI. Build is $20/month ($18 annually) for 1,500 credits, Max is $200 for 12× that, and Business is $50 per user with up to 25 seats. It runs on macOS, Linux and Windows, and is written in Rust.
