What three years costs

A subscription charges for as long as you use it, and the other buy-once license costs more up front. Schemity is paid once and keeps working when you stop paying.

  • DbSchema Pro (Personal)Perpetual license; $296 if you also renew updates every year $196
  • ChartDB Pro$25/month, up to 40% less billed yearly from $540
  • Schemity LicenseOne-time; $187 if you also renew updates every year $129

Single-user plans at their cheapest published billing, from each vendor's own pricing page, checked September 30, 2026.

Already own a license? Your license never expires. After the first year, updates are an optional $29/year renewal.

Team License: $499 one-time
For up to 5 engineers, with 15 machine activations shared across the team, 1 year of updates, and everything the License unlocks, for less than the $645 of five single Licenses. Whoever buys it signs in at license.schemity.com/seats to see every machine holding a seat and free one remotely, for a teammate who leaves or a laptop that dies.
Still a one-time purchase, not a per-user subscription. Need to pay by invoice or purchase order, activate machines with no internet access, pass a security review, or license more than 5 engineers? Tell me what you need

After the trial, offline design keeps working and your workspace JSON stays on your disk - nothing is deleted or locked away. What pauses is the live-database half and the Context Views built on top of it, until a license unlocks them again. Existing workspaces stay fully usable - only creating a new workspace is gated. Since v2.13.0 an expired trial also keeps receiving updates: what stays unlocked is basic diagramming, which seldom changes, so there is no reason to freeze it on an old version.
