warp vs ghostty, compared

These two are barely in the same category anymore, which makes the choice easier than most terminal comparisons. Warp is an agentic development environment: AI agents, a model picker, cloud orchestration, accounts, and metered credits, with a terminal inside it. Ghostty is a terminal, full stop: very fast, MIT licensed, no account, no AI anywhere. Decide whether you want intelligence built into the terminal itself or kept out of it, and the comparison decides itself. There is also a third position, at the end, for people who want AI agents but not inside the terminal.

what warp is now

If your mental model of Warp is "closed-source terminal with AI autocomplete," it is out of date twice over. Warp open-sourced its client in April 2026 under AGPL, with OpenAI as the founding sponsor of the repository. And the product is no longer pitched as a terminal at all: it is an "agentic development environment" built on Oz, Warp's platform for running agents locally or in the cloud. The terminal is one surface of a larger machine. It ships weekly, on a date-based version scheme, across macOS, Linux, and Windows from one Rust codebase.

What that buys you, per Warp's own docs:

• Agents built in. A model picker spanning OpenAI, Anthropic, Google, xAI, and hosted open-weights models, with auto-routing, BYOK, and custom endpoints. Third-party CLI agents like Claude Code and Codex run inside it as a supported integration.
• Cloud agents via Oz. Event-triggered and scheduled agents that run on Warp's infrastructure, not your machine.
• A modern terminal core. Blocks, a real input editor, workflows, launch configurations with session restore, and GPU rendering with published benchmarks. The performance claims are Warp's own, but nobody credibly calls Warp slow.

The tradeoffs are structural, not bugs. First launch requires being online so Warp can create a usage-metering ID, though the core terminal works offline afterward and login is optional. AI requests route through Warp's infrastructure, with zero-data-retention agreements and unconditional secret redaction per its privacy docs; on the free plan, telemetry must stay enabled to use AI features at all. AI usage is metered in credits: the $20 a month Build plan includes 1,500 of them, roughly $20 of usage at API rates. And Warp's docs state plainly that tmux is not supported. None of this is hidden; it is the shape of a product whose center of gravity is a platform, not a terminal.

what ghostty is, deliberately

Ghostty is Mitchell Hashimoto's MIT-licensed terminal: roughly 59,700 GitHub stars, around 635 contributors, daily commits, stable releases about every six months with 1.3.1 current since March 2026. It is a genuinely native app, Swift on macOS and GTK4 on Linux, with GPU rendering (Metal and OpenGL) that its README puts in the same class as Alacritty. There is no account, no telemetry service, no cloud, and no AI feature of any kind. Configuration is one text file; a settings GUI is planned but does not exist yet.

Its restraint is the product. It works out of the box with embedded fonts and hundreds of themes, supports modern terminal protocols (Kitty graphics, synchronized rendering, progress bars, a command palette since 1.2.0), and plays fine with tmux because it does not try to replace it. The gaps are the flip side: scrollback search only arrived in March 2026, there is no session persistence beyond macOS window restore, and the Windows build does not exist, with maintainers describing possible work late 2026 and explicitly not committing to it. Warp is on Windows today; Ghostty is not.

the ai question is the whole question

Everything above is downstream of one decision. Warp believes the terminal should become the place where agents live: it hosts them, meters them, and orchestrates them, and in exchange an account, a credit meter, and Warp's infrastructure enter your workflow. Ghostty believes the terminal should stay a dumb, fast pane of glass, and if you want AI you run it as a program, the way you run anything else. Neither is wrong. But you cannot have both in one app, so this is the axis to choose on; rendering speed and theme counts are noise by comparison.

how to choose

• You want AI agents built into the environment, cloud agents, and team features, and metered credits are acceptable: Warp.
• You want a fast, private, no-account terminal and you will run AI as CLI programs when you want it: Ghostty.
• You are on Windows: Warp. Ghostty is not there yet.
• You live in tmux: Ghostty. Warp's docs say tmux is not supported.
• Open source purism: both clients are open source now, but Ghostty is MIT with no service attached; Warp's client is AGPL and its Oz platform is a hosted service.

the third position

Disclosures first: crystl is our product, macOS only, closed source, free tier plus $170 a year for the orchestration features. If either answer above already fits you, take it.

The third position is for people who agree with Ghostty that agents should stay CLI programs, on your machine, on the subscription you already pay for, but agree with Warp that a plain terminal is a poor cockpit for several of them at once. crystl runs agents like Claude Code or Codex as the CLIs they are, locally, and never sits in the billing path for your tokens; no credits, no metering, no cloud execution. What it adds is the supervision layer a terminal lacks: every session's state visible at once, approval prompts as floating panels instead of scrolled-past text, each agent in its own git worktree, and history that survives a reboot. The full head-to-head with Warp is in Warp vs. crystl; many people happily pair crystl for agent work with Ghostty for everything else.
