Saggar vs Warp
An agentic development environment, and a window for the agents you already chose.
Warp started as a faster, friendlier terminal and now calls itself an agentic development environment. It still has the parts that made it good — blocks, a real command editor, and a fast Rust renderer — and it runs on macOS, Linux, and Windows. Since April 2026 its client is open source under the AGPL.
It is also much closer to Saggar than it used to be. Warp recognizes Claude Code, Codex, OpenCode, Gemini CLI, Pi, and about ten other agent CLIs, badges each tab with the agent's state, sends notifications when one needs you, and can publish a session so you can steer it from your phone's browser. Around that sits Warp's own agent and Oz, its platform for agents that run in Warp's cloud.
So the difference is no longer whether Warp can run your agents. It is scope. Warp is a whole environment with its own models, credits, and cloud. Saggar brings no model, runs only on a Mac, and does one job: telling you which of your sessions needs you next, including from your phone.
One correction to a claim that still gets repeated: Warp dropped its login requirement in November 2024, and the terminal works signed out. Its AI features need an account, and on the free plan telemetry has to stay on to use them.
What Warp does well
- Blocks and a command editor: every command and its output is a unit you can navigate, copy, share, and re-run, and input edits like a text field rather than a shell line.
- First-class support for third-party agent CLIs, including Claude Code, Codex, OpenCode, Gemini CLI, Copilot CLI, Amp, and Pi, with a rich input editor and inline code review.
- Vertical tabs that show each agent's state — in progress, blocked, done, error, or cancelled — beside its Git branch, worktree, pull request, and diff stats.
- Agent notifications as toasts, desktop alerts, and a mailbox you can filter to unread or errors and walk with the arrow keys.
- Remote Control publishes a running agent session to a link you can watch and steer from a phone, a browser, or another computer.
- Its own agent with a choice of models or your own API key, plus Oz cloud agents that keep working when your laptop is closed.
- An open source client under the AGPL, on macOS, Linux, and Windows.
Where Saggar takes a different line
- Saggar brings no model, no agent, and no credits. It runs the agent CLIs you already pay for and recognizes what they are doing, permission prompts included.
- Prompts, failures, and finished work form one priority-ordered queue across every project, walked with ⌘J, rather than badges and a mailbox you scan.
- The phone client is a native iPhone app rather than a published link. Pairing is gated on your account and approved at the Mac, and the relay routes sealed traffic it cannot read. It is in TestFlight beta.
- No account to use the Mac app, and no telemetry condition on any feature. Crash sharing is opt-in.
- A native Mac app in Swift and SwiftUI with a monitor dock for dev servers, and project state written to .saggar/ beside the code where agents can read it.

Which one
Pick Warp
Choose Warp if you want a better terminal and agent support in one app, if you need Linux or Windows, if open source matters to you, or if you want agents that run in the cloud while your laptop is shut. It now runs Claude Code and Codex well, and the terminal is free.
Pick Saggar
Choose Saggar if you work on a Mac, want no model or credits in your terminal, and the hard part is knowing which of six agent sessions needs you next, from a native phone app when you are away.
