atrium vs Warp
Warp turned a great terminal into an agentic development environment with its own agent, sold by the credit. atrium hosts the agent CLIs you already pay for — twelve of them — inside a tiling workspace that resumes after a crash and can keep agents working with the window closed.
atrium is the workspace around every coding agent you run. Tasks can launch into their own worktree-isolated rooms — terminal, agent chat, Monaco editor, browser, tasks, notes — journaled to disk and restored after a quit, crash, or reboot, with a keep-running setting that lets the background daemon continue agents after the window closes. It never proxies your agents' traffic and never meters them.
Warp is a GPU-accelerated, Rust-based terminal that has grown into an agentic development environment: its own multi-model agent, a native code editor with LSP, a code review panel, codebase indexing, project rules, MCP support, Warp Drive, and cloud agents that fire off webhooks, CI events, or Slack. The client was open-sourced under AGPL-3.0 in April 2026; the Oz cloud orchestration layer stays proprietary.

atrium features checked against the October 2026 build. Competitor features reflect public documentation from August 2026. Warp's feature set may have changed since — check their site and tell us if a row is out of date.
Warp's agent is metered: $20/month buys 1,500 credits, and heavy days cost more. If you already pay for Claude Code or a Codex plan, you'd be paying twice. atrium hosts those CLIs directly, on the subscription you already bought, and takes no cut — it never proxies a single request.
Warp gives you Warp's agent with a model picker. atrium runs the real vendor CLIs — Claude Code, Codex, Antigravity, Cursor Agent, Kimi Code, OpenCode, Pi, Grok, Hermes, Oh My Pi, Muse Code, and Goose — each with its own hooks, session resume, and capabilities, plus an MIT adapter SDK for the one that isn't in the list yet. Your agent choice isn't a model dropdown inside someone else's harness.
In the docs: every adapter atrium ships
Warp is worktree-aware: create one and it will index and review it separately. In atrium, choose worktree mode when launching a task and the checkout is created for the run. You can also move an existing chat into a worktree, then arrange terminals, editors, and browsers around the agents.
In the docs: dispatching a task into its own run · what a room holds
Warp restores conversations. atrium restores the room: pane layout, terminal scrollback, working directories, environment, and the live agent session behind each pane — after a quit, a crash, or a reboot, with a chooser for which rooms return.
In the docs: how persistence and recovery work
Everything above ships in the same app — these come with it.
Approval cards, streaming diffs, subagent drill-in, plan mode, steering mid-turn — rendered from each tool's own protocol.
Every running agent across the workspace, with live status and one-tap messaging.
Reusable runbooks and pre-configured agents, launched with +skill and ++agent mentions — across any adapter.
Comment on a live page like a design review, then send the thread straight to the agent that built it.
Cron and loop schedules with an overlap gate, a stall watchdog, and recovery of interrupted runs.
A navigable 3D night-sky map of your project history — galaxies, stars, supernovae.
WYSIWYG markdown with comment threads anchored to the text, plus a source toggle and book view.
Dracula, Nord, Catppuccin, Tokyo Night, Gruvbox, and more — or drop in your own JSON theme.
Warp has desktop clients on macOS, Linux, and Windows; atrium's desktop app runs on macOS and Windows, with no Linux client yet, though it can run projects and agents on self-hosted Linux boxes over SSH. Warp's terminal is genuinely better than atrium's — blocks, workflows, Warp Drive, and years of polish are hard to match, and its client is open source under AGPL-3.0. Its hosted agents can fire from webhooks, CI events, and Slack, while atrium's unattended runs come from cron and loop tasks on daemons you operate. If you don't already pay for a coding agent, one subscription that includes models is also simpler than assembling your own.
For agentic development, yes. Both give you an agent, a code editor with LSP, diff review, and terminals in one desktop app. The split is who provides the agent: Warp's is built in and billed by credits, while atrium hosts the CLI agents you already subscribe to — twelve of them — and never meters or proxies them. Warp has macOS, Linux, and Windows clients; atrium has macOS and Windows clients with self-hosted Linux and WSL SSH locations.
No. atrium is free during public beta and has no credit system. Your agents authenticate with their own accounts and talk directly to their own providers, so there's no second meter and no traffic through atrium's servers.
It runs the real thing. Every agent in atrium is the vendor's actual CLI — as a PTY in a terminal pane, or over the tool's own protocol in a chat pane, with approval cards, streaming diffs, subagent drill-in, plan mode, and steering. Nothing is reimplemented and nothing is scraped.
Not as a hosted service. Warp's cloud agents can be triggered by webhooks, CI events, or Slack; atrium does not provide those hosted trigger integrations. atrium instead runs background daemons on your own machine, self-hosted SSH servers, or paired computers, where task cards can fire on a cron schedule or loop with the app closed.
No — and we'd rather say so. Warp is a purpose-built terminal with blocks, workflows, and Warp Drive; atrium's terminal panes are solid PTYs with persisted scrollback, links, and search. atrium's advantage isn't the terminal, it's everything tiled around it.
No. Warp is a terminal emulator, and plenty of people will keep using it as their shell. atrium is the workspace agents live in — point it at the same repos and nothing about your git workflow changes.
Free during public beta. Bring the agents you already pay for — your code stays on the machines you choose.
