Warp
Warp is a GPU-accelerated terminal with block-based commands, AI features, and team sharing — a modern take on the traditional terminal emulator.
Warp is a GPU-accelerated terminal emulator that treats each command and its output as an interactive "block" rather than an endless stream. It adds AI features (natural-language command suggestions, explain output), team sharing, and a modern UI — positioning itself as the terminal for developers who want more than an xterm clone.
Why it matters
Warp popularized the idea that a terminal can have a real UI — command palette, input editor with multi-line support, clickable blocks, shareable sessions — without breaking compatibility with standard shells. It's one of the visible competitors in the "AI-first developer tools" category alongside SpaceSpider, Claude Code, and editors like Cursor.
Where Warp focuses on the single-terminal experience with AI overlays, SpaceSpider focuses on running many agentic coding CLIs in one grid layout. The two are complementary: you can run Warp as your daily terminal and SpaceSpider when you want a dedicated workspace for AI panes.
How it works
Warp renders its UI with Rust and GPU-based drawing (Metal on macOS, Vulkan/Direct3D elsewhere) instead of a classic grid-of-glyphs emulator. Under the hood each command still runs in a PTY with a real shell, so tools like vim and tmux work. Blocks are created by detecting prompt boundaries (via shell integration hooks) and grouping stdout/stderr of each command.
AI features use cloud LLMs: "Warp AI" suggests commands from natural language, explains errors, and summarizes output. Workflows and notebooks let teams share saved command sequences.
How it's used
Common patterns:
- Daily driver terminal with block-based history
- Natural-language command composition for unfamiliar CLIs
- Team workflows for onboarding (saved commands with placeholders)
- Paired with agentic coding tools — you can run Claude Code inside a Warp tab

FAQ
Is Warp open source?
The core terminal app is proprietary. Warp has released some components as open source and maintains a Rust crate wezterm-adjacent ecosystem, but the main product is closed.
Does Warp work on Linux and Windows?
Warp launched macOS-first. Linux support has been released; Windows support has lagged. Check the Warp site for current platform availability.
