OpenSwarm is an AI-first operating system built around letting swarms of agents run your machine for you—apps generate themselves, browsers control themselves, and you orchestrate many tasks at once instead of doing one at a time. It's currently in early access with a free waitlist only; no pricing is publicly stated.

ruOS — ruos.cognitum.one
ruOS is closest to OpenSwarm's pitch: a cloud desktop where agents do the actual work rather than just assist. It suits people who want a browser-based agentic desktop today rather than waiting on a waitlist. There's a free tier (ruOS Lite, browser desktop) with early access to the fuller platform; paid pricing beyond that isn't specified. The limitation is that the full agentic desktop tier's cost is undisclosed, so budgeting past the free Lite version is a guess.
OrgComputers — orgcomputers.com
OrgComputers is a dedicated shared workspace built specifically for AI agents, making it a direct conceptual match for OpenSwarm's agent-first environment. It suits teams wanting a workspace built around agents rather than retrofitted for them. No pricing information is published anywhere on the site, and there's no stated free tier, so cost and access terms are both unknown going in—a real gap for anyone trying to budget.
Spaces — spaces.ez-ai.io
Spaces gives one shared space where a team and its AI agents work side by side, with a genuinely free desktop app for solo use with unlimited local spaces. It suits individuals first, then small teams who need shared cloud spaces at $10.99/year per person ($0.92/month), with enterprise pricing on request. The limitation: multi-person collaboration requires the paid cloud tier, so the free plan is effectively single-player.
hob — hob.dev
hob is a professional workspace covering a whole agent stack, aimed at teams running agents at scale rather than solo experimenters. It offers one free month, then Pro at $50/mo ($30/mo with a founders discount), Pro+ at $75/mo, Teams at $100/seat/mo, and custom Enterprise pricing. It suits organizations ready to pay for structure and support. The limitation is cost: it's the most expensive option here once the free month ends.
Campfire — boringinfra.company/campfire
Campfire is a shared workspace for humans and coding agents specifically, distributed as open source via an install script. It suits developers who want a self-hosted, no-cost option focused on coding workflows rather than general computer use. No pricing model is stated beyond being free and open source. The limitation is scope: it's built around coding agents, not the broader "run your whole machine" ambition OpenSwarm describes.
M9R — app.m9r.workers.dev
M9R is a multiplayer space for AI coding agents and teams, with a free tier for individual use today and a Teams plan coming soon, pricing not yet finalized. It suits individual developers or small groups wanting real-time multiplayer agent sessions without commitment. The limitation is that team pricing is undecided, so it's not yet a safe long-term pick for organizations planning budgets around it.
Mantle — mantle.tools
Mantle is an open-source service builder for humans and AI agents, with a free self-hosted option offering unlimited sites and users, plus Mantle Cloud with a free tier and unspecified paid Team/Business/Enterprise plans. It suits teams building and hosting services rather than running an agent-operated desktop. The limitation is fit: Mantle is about building and hosting services, a narrower job than OpenSwarm's OS-level agent orchestration.
How to choose
If you want something closest to OpenSwarm's own idea—agents running a desktop—start with ruOS or OrgComputers, knowing both have gaps in disclosed pricing. If budget certainty matters, Campfire and M9R are free today. If you need paid, supported team tooling, compare hob's tiers against Spaces' much cheaper cloud plan. Mantle fits only if the job is building/hosting services, not running a computer.
FAQ
Is OpenSwarm free? No price is confirmed; it's early access with a free waitlist, not a stated free product tier. Which alternative is cheapest for teams? Spaces, at $10.99/year per person for shared cloud spaces, is the lowest stated team price. Which alternative is most similar to OpenSwarm's concept? ruOS and OrgComputers both frame themselves as agent-run workspaces/desktops, closest to OpenSwarm's "agents run the machine" idea.
