Paid license activation

After purchasing, you’ll receive a license key by email. Activate with:

Terminal window
simdrive auth sd-pro_aB12cD34...

Verify:

Terminal window
simdrive version
# → SimDrive 1.0.0aXX · License: pro · Expires: 2027-05-19

The activation is fully local. There is no phone-home after simdrive auth succeeds — the runtime verifies the Ed25519 signature on every tool call, no network required.

Licenses are machine-locked by default. To move:

Terminal window
# On the old machine
simdrive license release
# On the new machine
simdrive auth sd-pro_aB12cD34...

license release invalidates the local fingerprint binding so the same key can re-bind elsewhere. If you can’t run release on the old machine (lost, wiped, reimaged), see “Lost the old machine” below.

Keys live in your account at simdrive.dev/account — sign in with the email you used to purchase. You can also email hello@synctek.io with your purchase confirmation and we’ll resend.

We do not keep a copy of your local fingerprint. The key itself is what matters — store it in your team’s secret manager (1Password, Vault, GitHub Secrets).

Email hello@synctek.io with your account email and the new machine’s simdrive doctor output. We’ll force-release the binding from our side. Turnaround is typically < 24h.

Store the key in your CI secret manager and activate per job:

- name: Activate SimDrive
run: simdrive auth ${{ secrets.SIMDRIVE_LICENSE_KEY }}

For ephemeral CI runners (fresh VM per job) the per-machine binding renews automatically — no license release needed. For long-lived self-hosted runners, run simdrive auth once during runner provisioning.
