Best Orca IDE Alternatives (2026)

The best Orca alternative depends on why you're leaving. On a Mac, Agentastic is the closest upgrade: the same one-worktree-per-agent model in a native Swift app with Ghostty terminals, plus Docker, Apple Container, SSH, and cloud isolation as shipped features. If you need to stay cross-platform and open source, Emdash is the nearest match; for a scriptable Mac workspace, choose Superset, and for a chat-first app with hosted cloud, choose Conductor.

This guide covers Orca, the agent development environment from Stably AI at onorca.dev, not the GNOME screen reader of the same name. Because Agentastic is our own product, we stuck to what each vendor documents: every claim below was checked on October 5, 2026, against official docs, pricing, or source repositories, listed in the Sources section.

Why people look for an Orca alternative#

Orca is free, open source, and very active, so people rarely leave it over price. The reasons are usually about how it's built and what it leaves to you:

• It's an Electron app. Orca's terminal docs describe an xterm.js terminal, the same component VS Code uses, and its install notes treat it as an Electron app. Mac users who keep many agent sessions open often want a native app instead.
• Cloud and containers are do-it-yourself. Per-workspace cloud VMs and local Docker environments live under Settings → Experimental. You bring the provider, an agent writes a recipe into orca.yaml, and Orca runs the lifecycle scripts. Orca's ways-to-run guide is explicit that it doesn't sell hosted machines.
• Agents start in bypass mode. New agent launches in Orca come with each CLI's skip-permissions flag already filled in, on the theory that a throwaway worktree is a safe place to let an agent run. One switch in Settings → Agents moves every agent back to manual approvals, but teams with strict policies should know the default.
• Mobile is still beta. The companion app is in beta on iOS, and Android installs come from an APK rather than a store.
• You want something narrower or broader. Some people want just a terminal, others want chat, hosted cloud, or visual planning. Different tools cover those better.

What "agent development environment" means#

Orca calls itself an ADE, short for agent development environment. The label is new, but the idea is simple. An IDE assumes you write the code; an ADE assumes agents write most of it while you assign, supervise, and review. In practice, each task gets an isolated checkout, an agent session you can watch or steer, and a diff that stays attached to the task until it merges.

Agentastic, Superset, Emdash, and Conductor all fit that description, which is why they're the main Orca alternatives below. cmux and Claude Squad cover part of it, and the first-party apps cover it for a single provider. For a longer treatment, see what an agentic development environment is.

1. Agentastic: best native Mac alternative to Orca#

Agentastic uses the same model as Orca, one git worktree per task with the agent's own CLI in a terminal, but it's a native Swift app for macOS, and its terminals are GPU-accelerated Ghostty rather than xterm.js. Its catalog has 55 agent definitions, and anything you can run in a terminal can be added as a custom one.

• Best for: Mac users who like how Orca works but want a native app, with containers and cloud as regular features.
• Platforms: any Mac on macOS 14 or later. The iPhone companion is a public TestFlight beta (iOS 18+); Windows, Linux, and Android aren't supported.
• Isolation: a worktree unless you choose otherwise; a Docker or Apple Container sandbox per task; SSH hosts where sessions outlive your laptop's lid; or cloud agents on Modal, Fly.io, or Vercel Sandbox, set up by adding credentials in Settings instead of writing recipes.
• Price and license: free; closed source.

What Orca users will recognize: a built-in browser with Design Mode that agents can drive through the dev browser CLI, a diff viewer, GitHub pull requests, Linear issues, and usage tracking across several logins per provider. Also in Agentastic: Sentry issues can start a run, code review can use CodeRabbit or Greptile as well as Claude or Codex, a Kanban board groups worktrees by label, and manager agents coordinate other agents over days or weeks, a job Orca's orchestration layer handles behind an experimental setting.

Where Orca beats Agentastic: Windows, Linux, and Android; an MIT license; .worktreeinclude and shared-directory rules for gitignored files, where Agentastic relies on your setup script; a browser client for its self-hosted server; and the sheer size of its community.

Where Agentastic beats it: a native app with Ghostty terminals, containers and cloud agents that aren't experimental, plus Sentry intake and CodeRabbit or Greptile reviews, which Orca's docs don't mention.

2. Emdash: closest open-source, cross-platform alternative#

If you picked Orca for its license and its reach across operating systems, Emdash keeps both. General Action, a Y Combinator company, publishes it under Apache 2.0 for Mac, Windows, and Linux on both x64 and ARM64. Tasks run in their own worktrees, and around them you get a preview browser, pull-request and CI tools, recurring scheduled runs, SSH hosts, file editing, and one place to manage prompts, skills, and MCP servers.

• Best for: cross-platform teams that want an open-source alternative with a similar scope.
• Agents: a 25-plus catalog that includes Claude Code, Codex, Cursor, and Amp.
• Issues: Linear, Jira, GitHub, Notion, and Asana.
• Environments: per-task scripts can stand up a local, remote, or cloud environment and tear it down afterward; Emdash Cloud, the hosted version, is available through sales.
• Price and license: free to use; its GitHub repository shows roughly 5,900 stars.

Where it beats Agentastic: Windows and Linux builds and an open-source license.

Where Agentastic beats it: Swift rather than Electron, container sandboxes out of the box, managed cloud providers instead of hand-written provisioning, and a longer list of agent definitions.

3. Superset: best for scripting the workspace#

Superset (the coding-agent workspace, not Apache Superset) is the alternative for people who want to drive the whole environment from code. Its CLI, TypeScript SDK, and MCP server can create workspaces, launch agents, and run automations, and its in-app browser can be driven by agents.

• Platforms: macOS; the Linux AppImage is experimental, and Windows isn't available, per its FAQ.
• Agents: 22 built in plus any CLI agent.
• Price and license: one user is free. Pro costs $20 a seat monthly, or $15 a seat on yearly billing, and unlocks remote hosts, automations, Linear, Slack, and iPhone access. The source is published under the Elastic License 2.0.

Orca vs Superset#

The two apps are close relatives: both are Electron apps with worktrees, terminals, an editor, a browser with Design Mode, and a CLI. Orca is MIT-licensed, free, and runs on Windows and Linux, with iOS and Android companions. Superset is Mac-first, source-available, and charges per seat for remote hosts, automations, and mobile, but its SDK and relay-connected hosts are well documented for teams that want to automate.

Where Superset beats Agentastic: readable source, an SDK, and teardown scripts that run on workspace deletion.

Where Agentastic beats it: it's native rather than Electron, it offers container isolation, and its remote, scheduling, and iPhone features don't require a paid plan. See Superset alternatives.

4. Conductor: best for chat-first work and hosted cloud#

Conductor suits Orca users who want to step away from terminals. Every task is a workspace with a chat, a diff viewer, a checks tab, and a pull-request flow. Its cloud workspaces run in hosted sandboxes that keep going after your Mac sleeps, which is the hosted option Orca deliberately doesn't offer.

• Platforms: macOS only; Windows and Linux aren't available yet, per its install guide.
• Agents: four harnesses: Claude Code, Codex, OpenCode, and Cursor (via an API key).
• Price: nothing for local workspaces; $50 a month for Pro, which brings cloud workspaces, real-time collaboration, the API, and the iPhone app.

Orca vs Conductor#

Orca runs any CLI agent on any desktop OS for free, and leaves cloud compute to your own accounts. Conductor runs four agents on a Mac, wraps them in a chat interface, and sells hosted sandboxes and team collaboration on Pro. If your team spans Windows or Linux, Orca wins by default; if everyone is on Macs and wants managed cloud, Conductor is simpler.

Where Conductor beats Agentastic: hosted sandboxes with no provider account and multiplayer sessions.

Where Agentastic beats it: 55 agent definitions, containers, SSH machines, and cloud on your own accounts at no extra charge. See Conductor alternatives.

5. Paseo: best for a daemon you reach from anywhere#

Orca can run as a server that other clients pair with. Paseo is built entirely around that split. Its daemon puts each agent in a git worktree on a machine of your choosing, whether a laptop, a server, or a Docker container, and every interface, from the desktop and web apps to the phone apps and CLI, is a client of that daemon.

• Platforms: macOS 13+, Windows, Linux, web, iOS (App Store), and Android (Play Store or APK), per its downloads page.
• Agents: Copilot, OpenCode, Claude Code, Codex, and over 30 more.
• Price and license: free; the repository has used Apache 2.0 since a licensing change in August 2026.

Where it beats Agentastic: a client for nearly every device, including Android and the browser, and a server you can run headless.

Where Agentastic beats it: native Ghostty terminals and an LSP-backed editor on the Mac, plus per-task Docker or Apple Container isolation. See Agentastic vs Paseo.

6. Nimbalyst: best for planning-heavy work#

Nimbalyst keeps Orca's cross-platform reach but shifts the focus to planning. It surrounds Claude Code, Codex, OpenCode, and Copilot sessions with editable mockups, Excalidraw drawings, Mermaid diagrams, schemas, and spreadsheets, plus task tracking and worktrees.

• Platforms: macOS, Windows, and Linux, plus iOS and Android apps.
• Price and license: MIT-licensed and free for individuals; Teams lists at $20 per user monthly but is free while it's in beta.

Where it beats Agentastic: visual planning documents that agents can edit, on every desktop OS.

Where Agentastic beats it: agent breadth and isolation. It's built for running many coding agents at once rather than for planning documents. See Nimbalyst alternatives.

7. Claude Code Desktop: best first-party option across platforms#

If Claude is the only agent you really use, Anthropic's Claude Code Desktop may replace Orca outright. It runs parallel Claude sessions, each optionally in its own worktree under .claude/worktrees/, with a terminal, a file editor, diff review, app previews, and PR monitoring. Sessions can run locally, in Anthropic's cloud, over SSH, or in WSL on Windows.

• Platforms: Mac and Windows today, Linux as a beta.
• Price: included with paid Claude subscriptions (Pro, Max, Team, Enterprise); cloud sessions draw on your plan's usage instead of a separate compute bill.

Where it beats Agentastic: Windows and Linux, and first-party support.

Where Agentastic beats it: Codex, Gemini, Cursor, and dozens of other agents in the same workspace, and cross-provider review. See Agentastic vs Claude Code Desktop.

8. cmux: best if you mostly want the terminal#

Orca imports your Ghostty theme and font. cmux goes further: it's a native Swift terminal built on libghostty that reads your Ghostty config directly. Its sidebar tabs list each workspace's branch and listening ports, panes light up when an agent needs you, a browser can open beside the terminal and be scripted, and remote work happens over SSH or attached tmux sessions. Everything is controllable from its CLI or a Unix socket, but worktrees are yours to manage.

• Platforms: Mac only, plus an iPhone beta through TestFlight.
• Price and license: GPL-3.0-or-later and free; cloud VMs and the iOS app are part of paid plans starting at $50 a month.

Where it beats Agentastic: it's open source and does one thing, being a fast terminal for agents.

Where Agentastic beats it: per-agent worktrees, editing, diffs, and AI review without extra scripting. See Agentastic vs cmux.

Two more tools are worth knowing. OpenAI's Codex runs parallel worktree chats inside the ChatGPT desktop app on macOS, Windows, and Linux, and Claude Squad is an AGPL terminal app that pairs tmux sessions with worktrees.

When to stay with Orca#

Orca remains the right call if:

• Anyone on your team uses Windows or Linux, or you need an Android app.
• Your organization requires an OSI-approved open-source license.
• You want one free tool with no paid tier and are comfortable bringing your own cloud accounts.
• Jira, GitLab, Linear, and GitHub links at worktree creation cover your issue flow.
• You like its pace: the latest release when we checked, v1.4.220, was published on October 4, 2026, and release candidates ship even more often.

How to choose#

1. Platform first. Windows or Linux: stay with Orca, or try Emdash, Paseo, Nimbalyst, or Claude Code Desktop. Mac only: every option is open to you.
2. Native or Electron. If the app shell matters to you, Agentastic (Swift with Ghostty) and cmux (Swift with libghostty) are the native options. Orca, Emdash, and Superset are Electron apps.
3. Cloud and containers. If you want someone else to run the machines, Conductor Pro and Claude Code Desktop's cloud sessions do that. If you want cloud runs on your own accounts without authoring recipes, Agentastic handles the provisioning. Keep Orca's recipes or Emdash's scripts when you want full control.
4. Interface. Terminal-first: Agentastic, Superset, cmux, or Emdash. Chat-first: Conductor. Planning-first: Nimbalyst.
5. License. OSI open source: Emdash, Paseo, Nimbalyst, or cmux. Source-available: Superset. Closed source: Agentastic and Conductor.

How to switch from Orca to Agentastic#

Both tools run official agent CLIs on ordinary git branches, so your repository and agent accounts carry over unchanged.

1. Get the app from the download page or Homebrew (brew install agentasticai/tap/dev) on a Mac running macOS 14 or later.

2. Confirm your agent CLIs. Agentastic detects installed CLIs from your shell. Open Agent Home and check that your agents appear; if one doesn't, run it once in a terminal to finish sign-in and restart Agentastic.

3. Push open work. Orca worktrees are normal git worktrees. Commit and push the branches you want to keep, or merge them first.

4. Open the project. Cmd+O opens a repository folder, and the Quick Start walks through the window.

5. Port orca.yaml. Move scripts.setup into .agentastic/setup.sh, run chmod +x on it, and turn .worktreeinclude entries into explicit copy lines, since Agentastic's docs don't describe that file:

   bashCopy

   #!/bin/bash # .agentastic/setup.sh, ported from scripts.setup in orca.yaml set -euo pipefail # Copy what .worktreeinclude listed (literal paths, as in Orca) for item in .env .env.local config/local.yml; do src="$AGENTASTIC_MAIN_REPO_PATH/$item" if [ -e "$src" ]; then mkdir -p "$(dirname "$item")" cp -R "$src" "$item" fi done pnpm install

   Orca variable	Agentastic variable
   ORCA_ROOT_PATH	AGENTASTIC_MAIN_REPO_PATH
   ORCA_WORKTREE_PATH	AGENTASTIC_WORKTREE_PATH
   ORCA_WORKSPACE_NAME	AGENTASTIC_BRANCH (worktree folders take the branch name by default)

   If you used worktree.sharedDirectories to share node_modules or a cache, either install per worktree or link the directory from the main checkout inside the script. The setup scripts guide has fuller examples.

6. Replace scripts.archive and Quick Commands. Agentastic doesn't run teardown scripts automatically, so run cleanup before removing a worktree. Saved commands such as pnpm dev become repository shell tasks.

7. Move SSH worktrees. Use File → Add Remote. Agentastic reads ~/.ssh/config, including Include files, and its Tunnels tab replaces Orca's port forwarding.

8. Decide on approvals. If you relied on Orca's bypass defaults, the dev agent create command's --run-mode agentAutoApprove option uses each provider's unattended mode; see the dev CLI reference.

9. Pair your phone. Turn on Settings → Mobile App and scan the QR code with the iPhone app. There's no Android app, so keep Orca or Paseo for Android.

By default, Agentastic puts worktrees in a folder beside the repository; Git worktrees covers the alternatives.
