Open Swarm was an AGPL-3.0, local-first mission-control desktop app for launching, monitoring, approving, and coordinating multiple AI coding agents in parallel on a spatial canvas.

Open Swarm’s bet was that the bottleneck is supervision, not spawning: it put every agent on one pan-and-zoom canvas, funneled every tool-use request into a single approval workflow, and kept the whole thing on your machine with no cloud relay or telemetry. The bet ended in October 2026, when the project pivoted into a proprietary company product and the open-source repository became a signed-builds shell.

What it is
#

A desktop app (Electron shell over a React frontend and a FastAPI backend on port 8324) from openswarm-ai that runs Claude-powered agents through the Claude Agent SDK. The spatial dashboard is an infinite canvas of drag-and-drop agent cards, view cards, and embedded browser cards; agent chat streams over WebSockets with per-session cost tracking and persistent history. Its differentiators are a unified human-in-the-loop approval workflow (per-tool permissions of always-allow, ask, or deny, with batch approval from the dashboard), message branching that forks a conversation by editing a prior message, prompt templates, a skills library that syncs to ~/.claude/skills/, and an MCP tools library with registry browsing. Each agent gets its own git worktree and branch, with a diff viewer for uncommitted changes, and there are five built-in agent modes plus custom modes, interactive HTML/JS/CSS output views, dark and light themes, and keyboard shortcuts. It targeted macOS; Windows and Linux builds were documented as planned.

Status
#

Pivoted to proprietary: the open-source mission-control canvas documented here is no longer being developed. The repository now states that OpenSwarm “has moved in a new direction, and its development no longer happens here”, holds only the signed builds that installed copies check for updates, and declares the software proprietary (README fetched 2026-10-12). The git history was replaced: the repo carries a single commit dated 2026-10-03 (“releases shell”), where the note’s earlier verifications recorded an active source tree, and GitHub’s license detection moved from AGPL-3.0 to NOASSERTION. A v1.8.0 stable build was published on 2026-10-11 as a signed artifact, after the experimental line (exp.2 through exp.6, September 23 to October 6) this note tracked. The company behind the new direction, Open Swarm Inc., runs a waitlist-gated consumer assistant whose agents act on Gmail, Calendar, and Drive, with a privacy policy effective October 3, 2026 that covers advertising pixels, session recordings, and hashed-email ad measurement, the opposite of the no-telemetry positioning this note originally recorded. The last open-source state documented below is the AGPL-3.0 experimental line, about 826 stars and 171 forks as of 2026-10-12 (repository created 2026-03-13).

Star History Chart

The signal across the note’s whole life is a license story in three acts: a README MIT badge over an AGPL-3.0 file (September 2026), then a proprietary declaration with the source history replaced by a build shell (October 2026). The badge was the first piece of documentation not to trust, and the pivot was the second.

Strengths
#

  • The unified approval workflow is the strongest part of the design: one place to approve or deny tool calls across every agent.
  • Cost tracking per session and per agent, which the parallel-agent category mostly leaves to the provider dashboard.
  • Git worktree isolation per agent plus a diff viewer, so parallel work is contained and reviewable locally.
  • Skills, MCP tools, prompt templates, and message branching give it real depth beyond a chat multiplexer.
  • Fully local by design: no cloud relay, no telemetry, and the backend can be run directly for self-hosting.

Cautions
#

  • The project is proprietary and closed-source as of October 2026: the repository holds signed builds only, the source history is gone, and the AGPL-3.0 era is frozen at the last open release.
  • The “fully local, no telemetry” design described below belonged to the pre-pivot app; the successor product’s privacy policy describes advertising pixels, session recordings, and hashed-email ad measurement (effective 2026-10-03).
  • macOS only as of 2026-09-27; Windows and Linux were planned but not shipped before the pivot.
  • Built on the Claude Agent SDK and Anthropic models; the pre-pivot app was effectively single-provider.
  • The name collides with an unrelated Intrect-io/OpenSwarm Show HN project, which confuses search and comparisons.

Pricing
#

The pre-pivot app was free and open source (AGPL-3.0, last open line at v1.8.0-exp.6). The current signed builds are proprietary with no published price; the successor Open Swarm Inc. product is waitlist-gated with no pricing page as of 2026-10-12.

Compared to
#

  • Lanes: macOS board-first with real PTY sessions and an access-governance endpoint; the approval-centric canvas Open Swarm pioneered has no maintained open-source successor.
  • Conductor: the polished closed Mac worktree dashboard; it stayed closed but stayed alive, which the pivot proves was the harder half.
  • OpenRig: the Apache-2.0 local control plane with YAML-defined seats and approvals, the closest maintained open-source substitute for the pre-pivot workflow.

Bottom line
#

Not recommendable: the documented open-source canvas is frozen, the repository is a proprietary build shell, and the successor is a different product for a different audience. The note stays as the category’s second pivot record, after Flowise’s archive, and as the reason to read a project’s license file before its README.

Changes
#

  • 2026-09-27 - Created.
  • 2026-09-30 - Recorded the experimental release line advancing to v1.8.0-exp.4 (September 29) and refreshed star counts.
  • 2026-10-02 - Recorded the experimental release line advancing to v1.8.0-exp.5 (October 2) and refreshed star and fork counts.
  • 2026-10-07 - Added the openswarm-ai/openswarm star history chart to the Status section.
  • 2026-10-09 - Recorded the experimental release line advancing to v1.8.0-exp.6 (October 6).
  • 2026-10-12 - Recorded the pivot: the repository is now a proprietary signed-builds shell (single commit dated 2026-10-03, v1.8.0 build 2026-10-11), development moved to Open Swarm Inc.’s waitlist-gated consumer assistant with a 2026-10-03 privacy policy, and the Status, Cautions, Pricing, Compared to, and Bottom line sections were rewritten around the pivot.
