How Does AgentMux Compare?

Agent operating environment vs single-provider tools — multi-agent support, resource usage, and what it means to be first-class.

Agent Environment Comparison

Every tool below either runs agents or edits code with agent assistance. AgentMux is the only provider-agnostic orchestration UI for managing locally running agents — Claude Code, Codex Agent, Gemini Agent, and more — in one workspace.

"Local Agents" means running third-party agent CLIs locally — not just a tool's own IDE-embedded agent.

The key difference: local-first, subscription-free orchestration

Cloud multi-agent platforms exist now too — GitHub's Agent HQ runs Copilot, Claude, and Codex side by side across GitHub and VS Code. But that's cloud-hosted orchestration bundled with a Copilot subscription. Cursor and Warp can each run several of their own agent instances in parallel, but it's still one vendor's agent throughout — neither gives you a single view across Claude Code, Codex, and Gemini side by side.

AgentMux runs the real, official provider CLIs locally, side by side, with no subscription required beyond the providers themselves — your own login, your own model backend, not an AgentMux-run proxy. You see every tool call from every agent as it happens, catch regressions mid-task, and redirect any agent before it goes off track — all in one window, on your machine.

AgentMux
Any agent, local, one workspace

Resource Comparison

AgentMux bundles Chromium 148 via CEF — comparable download to Warp, faster startup than every Electron app here. The backend is pure Rust with no Node.js, no V8 GC, and no heap growth over long sessions. When you're running 10+ agent processes, backend stability matters more than who has the smallest installer.

AgentMux bundles Chromium 148 via CEF. RAM figures are at idle with one terminal pane open. Agent processes (Claude Code, Codex Agent, etc.) consume additional memory independently of the AgentMux host process.

Details

AgentMux

Rust + CEF (Chromium 148)
~175 MB
Download
150-350 MB
RAM

Bundles Chromium 148 via CEF for consistent cross-platform rendering — no WebView2 or WebKit quirks. Rust backend has no GC, no JIT, and no heap growth over time. Open source, no account required.

Warp

Rust + GPU
~205 MB
Download
150-400 MB
RAM

Requires account/login. Client is open source (AGPL-3.0) as of April 2026; the Oz agent platform remains proprietary. AI features require internet.

Memory spikes to 3+ GB reported in some configurations

Wave Terminal

Electron (Go + TS)
~155-200 MB
Download
200-500 MB
RAM

Open source. No formal benchmarks published. Standard Electron overhead applies.

Zed

Rust + custom GPUI
~80 MB
Download
100-250 MB
RAM

Fastest startup of any editor. ~50% less memory than comparable Electron editors per Zed's own benchmarks. Limited extensions.

Cursor

Electron (VS Code fork)
~230 MB
Download
400 MB-3 GB+
RAM

Closed source VS Code fork. Progressive slowdown requiring daily restarts.

Multi-day sessions: 20-40+ GB reported

Windsurf

Electron (Code OSS fork)
~220 MB
Download
500 MB-4 GB+
RAM

Recommends 16 GB RAM. Cascade AI context loader adds significant overhead on large projects.

Language server spikes to 10 GB+ reported on large codebases

Why the difference?

Consistent rendering everywhere
AgentMux bundles Chromium 148 via CEF — the same renderer on Windows, macOS, and Linux. No WebView2 version mismatches on Windows, no WebKit rendering bugs on macOS, no platform-specific workarounds. Every user sees identical behavior regardless of OS.
Chromium + Rust — not Chromium + Node.js
Electron apps bundle Chromium and Node.js together — you get V8's garbage collector, JIT warmup, and unpredictable heap growth on both sides. AgentMux bundles Chromium for the UI but the entire backend is Rust: no Node runtime, no npm, no GC pauses. Memory at startup is memory an hour later. When you're running 10 parallel agents, the last thing you want is the orchestrator itself becoming the bottleneck.
Local-first, not cloud-dependent
AgentMux runs entirely on your machine by default. No login required, no background sync, no telemetry for local usage. Your terminal sessions, commands, and agent output stay local — an opt-in cloud relay exists only for inter-agent messaging across hosts.
Open source
Apache 2.0. You can read the code, build it yourself, or fork it. No opaque update mechanism, no server-side feature flags, no subscription required to access capabilities.

Free, open-source, and runs entirely on your machine. No account required.
