Terminal built for running AI coding agents like Claude Code, Codex, and Gemini CLI, with shared context, interactive code review, and multi-session management.

Warp is a terminal redesigned around the way developers actually work with AI coding agents. Rather than treating the terminal as a place to paste commands, it gives you a structured environment where agents run, report back, and wait for your input, all without switching windows or losing context.
It works with the major AI coding agents out of the box:
The interactive code review feature is one of the more practical differentiators. When an agent finishes a task, you can review its changes, leave inline comments, and send them back for revision without leaving the terminal. It's designed to close the gap between an agent's first pass and something actually ready to ship.
Vertical tabs let you run multiple sessions at once, each tagged with metadata like git branch, worktree, or pull request. Notifications surface when an agent needs a decision, whether that's approving a command, confirming a plan, or acknowledging a finished task.
For teams, Warp includes SAML SSO, role-based access control, SOC 2 Type 2 compliance, secret redaction with custom regexes, and integrations with 1Password and LastPass. You can bring your own LLM and keep everything inside your own infrastructure. Centralized admin controls let you set agent permissions and track usage across the whole team.
Warp runs on Mac, Linux, and Windows. It's trusted by over 800,000 developers and sits in the growing category of AI terminals built for agentic workflows.
