Agents UI
A fast, polished terminal with AI features and a modern block-based UI, but proprietary and account-gated. If it isn't the right fit, here are the strongest Warp alternatives in 2026.
1. Agents UI
The only terminal designed from the ground up to run, orchestrate, and steer AI coding agents — with SSH, file editing, and a Python SDK built in.
- Purpose-built to run agents like Claude Code, Codex, and Gemini CLI side by side
- Orchestrate mode turns one goal into tasks dispatched across multiple sessions
- Built-in SSH host management, file transfer, and port forwarding
Platforms: macOS · Price: Free · Open source: Yes · Compare with Warp
2. iTerm2
The mature, deeply configurable macOS terminal — unmatched for manual power-user workflows, but not built around AI agents.
- Extremely mature and stable with deep customization
- Metal GPU renderer and tmux integration
- Python scripting API for automation
Platforms: macOS · Price: Free · Open source: Yes · Compare with Warp
3. Ghostty
A blazing-fast, native terminal focused on speed and simplicity — great for manual work, no agent features.
- Very fast GPU-accelerated, native rendering
- Sensible defaults with minimal configuration
- Native splits and tabs
Platforms: macOS, Linux · Price: Free · Open source: Yes · Compare with Warp
4. Kitty
A fast, scriptable terminal with a powerful remote-control protocol — flexible for manual work, not built for agents.
- GPU-accelerated with a rich remote-control protocol
- Kittens extend functionality (image preview, SSH, diffing)
- Native splits, tabs, and layouts
Platforms: macOS, Linux · Price: Free · Open source: Yes
5. Alacritty
The fastest bare-bones terminal — pair it with tmux for anything beyond a single pane.
- Extremely fast and lightweight
- Cross-platform and simple
- GPU-accelerated rendering
Platforms: macOS, Linux, Windows · Price: Free · Open source: Yes
6. WezTerm
A powerful cross-platform terminal with a built-in multiplexer and Lua config — great for remote work, manual-first.
- Built-in multiplexer with persistent remote sessions
- Cross-platform with Lua-based configuration
- Native SSH client and GPU rendering
Platforms: macOS, Linux, Windows · Price: Free · Open source: Yes
7. Apple Terminal
Fine for occasional commands, but underpowered for serious development or agent workflows.
