What is Turnstone?

Turnstone is a Mac app for running a team of AI agents. Its facts page, read 11 Nov 2026, says “Each Agent has its own job, its own model and its own memory.” Its Y Combinator page lists it in the Winter 2026 batch as “The best model-agnostic Grokbot alternative”.

You start with a Chief of Staff, which the home page says “sets up an Agent for each part of the job.” Every Agent shares one memory, the Brain, which “is stored as plain files on your Mac that you can open and correct.” The home page links comparison pages against 12 rivals, so this page returns the favour.

How does Turnstone use your subscriptions?

It signs in with plans you already pay for and can move an agent to another one when a plan runs out. The home page says “Sign in with ChatGPT, Claude, Grok or Cursor, or use an API key.” The YC page adds: “When a subscription runs out, your Agent can automatically move to another connected subscription with available capacity.”

When the first battery fades to empty, the next one slides into place and the beam stays lit. Tapping the flashlight drains the current battery and the next one takes over.
When a subscription runs out, a Turnstone Agent can move to another connected one, per its Y Combinator page, read 11 Nov 2026.

Is Turnstone free?

Yes on a Mac, and its Cloud add on is paid and not out yet. Turnstone’s pricing page, read 11 Nov 2026, lists Free at $0 “forever” with your own subscription or API key. Cloud is marked “Coming soon” at $49 per month, with a waitlist, and on 11 Nov 2026 the home page offered the first 1,000 people a free first month.

Animation. On a white background, two envelopes sit side by side. The first reads Turnstone for Mac and slides out a card that says $0 forever. The second reads Cloud and slides out a card that says $49 a month, with a small tag that reads Coming soon. Tapping an envelope tucks its card back in and slides it out again.
Turnstone for Mac is $0 forever and Cloud is listed at $49 a month, per its pricing page, read 11 Nov 2026.

Why look for a Turnstone alternative?

Mostly for platform, source code or cloud. The facts page lists “Windows, Linux, Android” as “Not available”, and Turnstone Cloud, the iPhone app and the web app as “Coming soon”. Turnstone’s own OpenClaw comparison answers the open source row with “No. Closed source.”

None of this makes it a bad tool. This list is for people comparing tools like Turnstone before they pick.

5. OpenClaw: if you want open source in your chat apps

OpenClaw is a free assistant that lives in your chat apps. Its README, read 11 Nov 2026, calls it “an open-source AI assistant that runs on your own computer and meets you in the channels you already use”, with “no paid tier, hosted service, or token”.

How to choose

Our view: pick Claude Cowork if you pay for Claude and want work to go on with your laptop closed. Pick Munder Difflin for a free, open source team of agents on macOS, Windows or Linux. Pick Grok Bot if you already have Premium or higher on The X Subscription, Perplexity Teammates if you already pay for its top plan, and OpenClaw for MIT code in your chat apps. Or stay on Turnstone if you work on a Mac and want several AI plans behind one team.
