Private beta

An unsigned Windows test beta is being prepared for a small tester group, with manual downloads only. Downloads will appear after Windows installation and subscriber-access checks pass. An active subscription is required for agent execution; a subscription does not make an unpublished build available.

Preview setupOpen Nexus, prepare a workspace, and configure model routes before subscribing.

Pro $40 / Max $100 / Ultra $200 /moRun governed agents with open-source models on your device plus hosted Arbiter 27B and Doubleword credits and Orrery Cloud.

Paid tiers auto-renew monthly via Stripe; cancel anytime. Hosted-model prompts are proxied through Orrery Cloud. Terms | Privacy.

Request access

No permanent unpaid tier or public trial is offered at launch. Preview users can inspect setup; active subscribers can run agents. For beta questions, email kt@ephemerent.com.

Quick start

This test beta is unsigned: Windows may warn or block it, and its publisher is not authenticated. Compare the ZIP checksum before extracting it; do not disable operating-system protections.
Orrery opens the Agents/Nexus desktop shell with a seeded sandbox workspace — no other installs required.
Sign in from Settings -> Account and subscribe - hosted Arbiter 27B and Doubleword credits work with zero provider-key setup.
Use Nexus to open a workspace, pick a hosted route, send work, and review proof, boundary, and usage receipts.
Release notes and checksums accompany the test ZIP. Updates are manual: close the app, preserve your work, and download a newly reviewed ZIP from this page. Automatic installation is disabled for this beta.
