Best Superset alternatives in 2026 (Windows, Linux, truly open source)

Short answer

The best Superset alternative depends on why you are leaving. As of October 2026, Superset does not support Windows and its Linux support is experimental, and it is source-available under the Elastic License rather than OSI-approved. Four alternatives meet all three criteria in the title (Windows, Linux and an OSI-approved license): Orchestrator.inc (formerly Agent Orchestrator), Orca, Emdash and Nimbalyst. Choose Orca for IDE-style multi-forge PR tooling, Emdash if work arrives from Linear or Jira, Nimbalyst if you work from documents, and Orchestrator if you want CI and review feedback to reach the agent without a click.

At a glance

All competitor details are as of October 2026.

The problem in practice

You like Superset's model of parallel agents in worktrees, but a teammate is on Windows, you work on Linux, or your legal team wants an OSI-approved license.

Why Orchestrator.inc is listed first

Orchestrator is listed first because it meets every criterion in the title and also sends CI and review feedback to the agent without a click. This is its own site, so weigh its limits too. Orca, Emdash and Nimbalyst meet the same criteria, and each is a better fit for some teams.

The options

Orchestrator.inc

A free, Apache-2.0 desktop app with a local daemon and an ao CLI. Every session gets its own worktree and branch, and the daemon follows its PR on GitHub or GitLab, sending failing checks, requested changes and merge conflicts to the session that owns it.

• Strengths: macOS, Windows (native ConPTY) and Linux; 38 harnesses; automatic PR feedback; planner and reviewer agents; a Files panel with diffs and inline comments; resumes after usage limits reset; remote hosts on your own servers; Orchestrator Cloud; iOS and Android app.
• Limits: no built-in code editor; no Linear or Jira intake; no Slack notifier; remote machines run its host rather than plain SSH; Electron.
• Best for: mixed-OS teams who want each agent to carry its PR to the merge decision.

Orca

An MIT app that describes itself as an agent IDE. It runs on all three desktop platforms and supports many CLI agents. PR tooling includes AI-drafted and stacked PRs, auto-merge, inline review comments, failed checks with logs, and a button that hands failed checks to an agent. It works with GitHub, GitLab, Bitbucket, Azure DevOps and Gitea.

• Strengths: multi-forge PR tooling, a design-mode browser, SSH hosts, iOS and Android.
• Limits: no sessions Kanban; sending CI failures to an agent is a manual click.
• Best for: developers who want an IDE-style app across several Git hosts. See Orchestrator.inc vs Orca.

Emdash

An Apache-2.0 agentic development environment for macOS, Windows and Linux, including ARM64. It detects many CLI agents and keeps pre-warmed worktrees so tasks start quickly. Its standout is issue intake from Linear, Jira, GitHub, GitLab and other trackers, plus SSH remote work.

• Strengths: broad tracker intake, fast worktree start, remote parity.
• Limits: no mobile app, no planner agent, no automatic CI-fix loop.
• Best for: teams whose work arrives from Linear or Jira. See Orchestrator.inc vs Emdash.

Nimbalyst

Formerly Crystal, an MIT desktop app with an iOS companion. Its focus is documents: markdown with AI diffs, mockups, whiteboards and trackers next to a session kanban.

• Strengths: document-centric workflow, cross-platform, iOS app with push and voice replies, free for individuals.
• Limits: fewer agents; no planner; CI tracking not documented.
• Best for: solo developers who want specs, wiki and sessions in one place. See Orchestrator.inc vs Nimbalyst.

Conductor

A native Mac app with cloud workspaces and an iOS app. Its Checks tab tracks CI and review threads, forwards failing checks to the agent, and can block merge on failures. It misses the title's criteria but is closest to Superset's cloud and team features.

• Strengths: native Mac experience, checks and review integration, cloud workspaces, team features and a SOC 2 report on paid plans.
• Limits: macOS only; closed source; supports Claude Code, Codex, Cursor and OpenCode.
• Best for: Mac users who want a hosted, team-ready product. See Orchestrator.inc vs Conductor.

Claude Squad

An AGPL-3.0 terminal app that pairs one worktree with one tmux session per agent and attaches you to the agent's own interface.

• Strengths: lightest option, works over SSH, any CLI agent.
• Limits: no native Windows build; no PR, CI or review view; AGPL is copyleft.
• Best for: terminal-first developers on macOS or Linux. See Claude Squad alternatives.

Where Superset is a good fit

• You want a CLI, a TypeScript SDK and an MCP server in one product.
• You want Slack and Linear integrations.
• You need SSO, SCIM, audit logs or a SOC 2 report from an enterprise tier.

Where Orchestrator fits better

• Teams on Windows or Linux who want the same app as their Mac colleagues, with the source under Apache-2.0.
• Workflows where review and CI feedback should reach the agent on its own, polled from GitHub or GitLab with no webhooks or GitHub App.
• People who want agents on their own servers or VMs, driven from one desktop app, or in Orchestrator Cloud.

How to choose

• Orca if you want IDE-style PR tooling across several Git hosts.
• Emdash if your tasks come from Linear, Jira or another tracker.
• Nimbalyst if your work starts from specs and wiki pages.
• Conductor if you are on a Mac and want a native app with team features.
• Claude Squad if you want a terminal app and nothing more.
• Orchestrator if you want CI failures, review comments and conflicts to reach the owning agent on macOS, Windows or Linux.

Pricing

Running Orchestrator on your own machines is free and open source (Apache-2.0), with no account needed; you bring your own agent subscriptions or API keys. Optional Orchestrator Cloud plans, for agents that keep working while your laptop is closed, are Starter at $20/month and Pro at $40/month, with Enterprise pricing on request. Orca, Emdash, Nimbalyst's individual tier and Claude Squad are also free. As of October 2026, Conductor has a free local tier, Pro at $50 per month and Teams at $60 per user per month, and Superset has a free tier and Pro at $20 per user per month.
