What can the agents actually do?

Anything you do on your computer: agents use your browser, your apps, and connected tools. Examples include opening six browsers in parallel to research a topic, building an app when you describe one, validating a problem across Reddit, X, and Hacker News simultaneously, and finding leads and drafting first emails.

What is the agent marketplace?

A set of prebuilt multi-agent apps agents use inside OpenSwarm, including Lead Finder (5 agents), Problem Validator (6 agents), Post Harvester (3 agents), and Social Footprint Finder (6 agents).

The site does not mention open-source licensing; OpenSwarm is a product of Open Swarm Inc.

OpenSwarm — The free AI desktop for Mac where many agents work at once

OpenSwarm is a free AI desktop application for Mac where multiple AI agents work in parallel. Instead of one agent in one chat, users get a canvas view of a whole 'swarm' of agents, each with its own browser, apps, and tools. Agents can complete end-to-end tasks on the user's computer — browsing the web, building on-demand apps, searching Reddit/X/Hacker News simultaneously — and the user can watch progress, step in, and collect finished work.

Key Features

Many agents working at once

A desktop environment where multiple agents operate in parallel rather than one agent handling a single task in a chat window, all visible on one canvas.

Agents use your browser, apps and tools

Each agent gets its own browser, apps, and connected tools so it can finish the whole task instead of just giving instructions.

Parallel browsing

A single request can open six browsers at once, with each agent reading its own set of pages (shown with a 'find best food in Berkeley' example).

Apps on request

Describe a tool you need and an agent builds it; the app then sits in your launcher alongside your others.

Problem Validator

A prebuilt swarm for validating problems: each source (Reddit, X, Hacker News, review sites) gets its own agent searching simultaneously.

Agent marketplace

Prebuilt multi-agent apps such as Lead Finder (5 agents), Problem Validator (6 agents), Post Harvester (3 agents), and Social Footprint Finder (6 agents).

Team workflow presets

Ready-made swarms for sales and outreach, operations, recruiting, and research, including a demo that finds 50 Series A fintech startups in New York and drafts a first email to each founder.

Supervision and handoff

Watch the whole swarm on one canvas, step in when you want, and pick up the finished work.

How It Works

Launch a task

Ask for something in natural language, e.g. 'Catch me up on my texts and LinkedIn' or 'Find 50 Series A fintech startups in New York and draft a first email to each founder.'

The swarm splits the work

OpenSwarm assigns agents to the job — opening parallel browsers, spawning per-source agents, or building an app on the fly.

Watch, step in, collect

All agents are visible on one canvas; you can intervene while they work and pick up the finished output.

Pros & Cons

Pros

Truly parallel multi-agent execution rather than a single chat agent
Agents act directly on your machine (browser, apps, connected tools) to complete tasks end-to-end
Visual canvas for watching and supervising all agents at once
Ships with ready-made multi-agent apps (Lead Finder, Problem Validator, Post Harvester, Social Footprint Finder)
Free to use, per the site's positioning
Agents can build new apps on request that persist in your launcher

Who It's For

Best for

Mac users who want to delegate multi-step work (research, outreach, ops) to several AI agents at once
Sales, operations, recruiting, and research professionals with repetitive multi-app workflows
Founders and indie hackers validating problems against Reddit, X, and Hacker News in parallel
Anyone who wants agents that execute tasks on their computer rather than giving instructions

Not ideal for

Windows or Linux users (the product is advertised as a Mac desktop)
People who need a product available for immediate download rather than waitlist-based early access

Use Cases

Sales and outreach: finding the right people, learning what they care about, and preparing a first email for every lead (shown with LinkedIn, Crunchbase, HubSpo

Operations: handing repetitive, multi-step work to a swarm

Recruiting

Research: parallel browsing across many sources

Idea validation: searching Reddit, X, Hacker News and review sites for real people with a problem

Building small personal tools/apps on request (e.g. a daily brief app)

FAQ

What is OpenSwarm?

OpenSwarm is a desktop application for Mac where many AI agents work at once. Each agent gets its own browser, apps, and tools, and you can watch the whole swarm on one canvas, step in when you want, and pick up the finished work.

How is it different from a chat-based AI assistant?

Most AI tools give you one agent in one chat that works on a single task while you wait. OpenSwarm runs many agents in parallel, each with its own browser and tools, so bigger jobs get split up and completed for you rather than handed back.

What does it cost?

OpenSwarm is advertised as 100% free. You currently join a free waitlist for early access.
