Desktop Apps for Coding Agents: The 2026 Landscape, Compared

Quick answer

Six apps define the category in mid-2026: OpenAI's Codex app and Anthropic's Claude Code desktop (official, single-vendor), Conductor and Sculptor (independent agent runners), and Nimbalyst and AIDEN (kanban-style orchestrators). Only AIDEN and Nimbalyst manage mixed Claude Code + Codex fleets; only AIDEN adds a spec gate before agents code.

The field: Codex app · Claude Code desktop · Conductor · Sculptor · Nimbalyst · AIDEN
Multi-vendor agents: AIDEN (Claude Code + Codex) and Nimbalyst; the rest are single-vendor
Open source: Sculptor and Nimbalyst; the others are free or freemium closed source
Not covered here: General computer-use assistants, this page is coding-agent managers

What This Category Is (and Isn't)

One disambiguation before the roundup: "AI agent desktop app" often means a general computer-use assistant, an agent that operates your whole desktop, clicking buttons and filling forms. That is a different category, and this page does not cover it. What we compare here are coding-agent managers: native apps that run and organize coding agents like Claude Code and Codex, launching sessions, isolating them from each other, surfacing their status, and structuring review.

They are also distinct from AI editors. Cursor or Windsurf put the agent inside your editing surface; the apps below sit above the agents, closer to a control room than an editor, and most assume you keep your existing editor for reading and touching code. If your question is actually "which AI IDE," start with best agentic IDEs in 2026 instead. The category exists because parallel agent sessions became normal and terminals manage them badly, the full argument is in managing multiple Claude Code sessions.

The Six Apps, Fairly

OpenAI Codex app

OpenAI shipped the official Codex desktop app for macOS in February 2026 and Windows in March 2026, positioning it as a "command center" for Codex agents. It does the core of this category well: parallel agents isolated in git worktrees, managed from a native UI instead of a pile of terminals, from the vendor itself. The structural limit is the obvious one, it runs OpenAI models only. If your workflow is all-in on Codex, it is the default choice; if you also run Claude Code, it manages half your fleet.

Claude Code desktop app

Anthropic's desktop app for Claude Code, redesigned in 2026, brings sessions out of the terminal with a native interface and an in-app browser, useful for agents doing web-facing work. It is the closest official experience to Claude Code itself, with your existing login and limits. Like the Codex app, it is single-vendor: Claude only, no Codex, and its model is a session manager rather than a board with a process around it.

Conductor

Conductor is a free, YC-backed Mac app that runs parallel Claude Code agents in git worktrees, one of the earliest and most polished independent takes on the category, and genuinely pleasant to use. Its constraints: Apple Silicon only (no Intel Macs), Claude- centric, and no spec gate or team layer, it manages sessions, not process. We compare it with AIDEN in depth on the Conductor alternative page.

Sculptor

Sculptor, from Imbue, is open source and takes the strongest isolation position in the field: each agent runs in its own Docker container rather than just a worktree, which means agents can install packages or run services without touching your machine. It ships for Mac (Apple Silicon) and Linux, notable as one of the few Linux options. The trade: Docker is a heavier substrate, and the app is an agent runner, not a planning board.

Nimbalyst

Nimbalyst is the free, MIT-licensed entry: cross-platform, with a kanban view over coding-agent sessions. Since Vibe Kanban, the project that defined the agent-kanban category, shut down in April 2026, Nimbalyst fills the free-and-open-source niche, and if open source is a hard requirement, it is the honest recommendation. What it does not have is AIDEN's process layer: no enforced spec gate, no team mode.

AIDEN

AIDEN, ours, so calibrate accordingly, is a macOS app (macOS 12+, including Intel Macs, which Conductor and Sculptor do not cover) built around a spec-first kanban board: Stories → Spec Review → In Progress → Review → Done, with an enforced spec approval before any agent codes and an automated worktree per story. It is the only app here that runs both Claude Code and Codex as first-class agents on one board, adds a team mode for shared boards, and stays local-first and BYOK, your CLIs, your keys, your machine. Free for one project. The board's design is covered in a kanban board for Claude Code.

Which One, for Whom

All-in on one vendor

Take the official app: the Codex app if you're on OpenAI (and the only Windows-native pick here), Claude Code desktop if you're on Claude. First-party support and zero extra process. Revisit only if you add a second vendor or want a board.

Mac user, wants a polished free runner

Conductor, if you're on Apple Silicon and Claude-only. It's the lightest-touch way to get parallel worktree agents in a nice UI. Intel Mac users are excluded, which is where AIDEN is the fallback.

Open source required, or on Linux

Sculptor for maximum isolation (Docker per agent, Mac ARM + Linux), Nimbalyst for a cross-platform kanban that's MIT-licensed. Both free, both inspectable, both without a spec gate.

Mixed fleet, or you want process, not just visibility

AIDEN: the one app here running Claude Code and Codex on one board, with an enforced spec gate, automated worktrees, and team mode, on any Mac from macOS 12 up, Intel included. Free for one project, so trying it costs nothing.

If part of your decision is board-versus-runner rather than app-versus-app, the case for the board is made in a kanban board for Claude Code, and the post-Vibe-Kanban options are mapped in Vibe Kanban alternative.

FAQ

What is a desktop app for coding agents?

A native app whose job is running and managing coding agents, tools like Claude Code and Codex, above the terminal: launching sessions, isolating them in worktrees or containers, showing their status, and organizing review. It is distinct from an AI editor like Cursor, where the agent lives inside your editing surface, and from general computer-use assistants that operate your whole desktop.

Aren't the official apps from OpenAI and Anthropic enough?

For single-vendor workflows, often yes, and they are both free apps on top of your existing plan. Their shared limit is vendor lock: the Codex app runs only OpenAI models and Claude Code desktop runs only Claude. If your fleet mixes Claude Code and Codex, or you want a kanban process with a spec gate rather than a session list, that is where third-party apps like AIDEN and Nimbalyst come in.

Which desktop apps run both Claude Code and Codex?

Of the apps compared here, AIDEN runs both CLIs as first-class agents on one board, and Nimbalyst is built around sessions from multiple coding-agent CLIs. The official apps are single-vendor by design, Conductor is built around Claude Code, and Sculptor runs Claude Code agents in Docker containers.

Do any of these work on Windows or Linux?

The Codex app shipped for Windows in March 2026, and Nimbalyst is cross-platform. Sculptor covers Mac (Apple Silicon) and Linux. Conductor is Mac-only and Apple Silicon-only; AIDEN is macOS 12+ including Intel Macs. If you are on Linux, Sculptor and Nimbalyst are the realistic short list from this roundup.

Which of these apps are free or open source?

Sculptor (from Imbue) and Nimbalyst (MIT-licensed) are open source; the Vibe Kanban community fork, covered on our Vibe Kanban alternative page, is as well. Conductor and the two official apps are free but closed source. AIDEN is closed source with a free tier for one project, then $19/mo Solo. In every case you bring your own agent subscription or API key, the apps orchestrate, they don't resell inference.
