Licensing & tiers
DioscHub is licensed in three tiers — Free, Pro, and Enterprise. A tier decides two things: how much you can create (resource limits) and which capabilities are unlocked (features). This page sets out what each tier includes and how you apply a license, so you know which entitlements your deployment has.
How much each tier lets you create
Section titled “How much each tier lets you create”Resource limits are enforced when you create something — reach the cap for your tier and DioscHub declines the create, naming the tier that would allow it.
| Resource | Free | Pro | Enterprise |
|---|---|---|---|
| Assistants | 1 | 3 | Unlimited |
| MCP instances | 1 | 3 | Unlimited |
| Knowledge bases | 1 | 5 | Unlimited |
| Toolsets | 5 | 50 | Unlimited |
| Roles per assistant | 3 | 10 | Unlimited |
| Sitemap entries per assistant | 10 | 50 | Unlimited |
| Admin users | 1 | 5 | Unlimited |
| Model configurations | 1 | Unlimited | Unlimited |
When a deployment moves to a lower tier, DioscHub does not delete anything over the new cap. It keeps the newest items within budget active and sets the excess aside; moving back up reactivates them. Your configuration is preserved across a tier change.
Which capabilities each tier unlocks
Section titled “Which capabilities each tier unlocks”Higher tiers unlock capabilities the lower tiers gate off. The ones with direct effect on a deployment:
- Pro unlocks file handling (users uploading files into a chat), custom branding (below), business intelligence reporting, and per-Role capabilities such as session-history lookup and custom approval dialogs.
- Enterprise adds the admin role hierarchy — custom administrator roles and the RBAC ladder — and multi-instance federation, the licensed capability behind horizontal scaling.
”Powered by DioscHub” on the Free tier
Section titled “”Powered by DioscHub” on the Free tier”On the Free tier, the chat widget shows a non-removable “Powered by DioscHub” attribution. It is enforced on both sides: the backend serves the default styling and the widget renders the attribution regardless of what branding is configured.
From Pro upward, custom branding is unlocked — you replace the attribution with your own, and the backend stops forcing the default styling. The attribution is a branding entitlement, not a notice about the assistant; for how AI interaction is disclosed to users, see AI disclosure.
How a license is applied
Section titled “How a license is applied”A license is installed as an environment variable when you deploy DioscHub — there is no in-app upload. With no license, a deployment runs on the Free tier.
- A Pro license activates against the DioscHub license service and is cached locally, so it keeps working through brief connectivity gaps.
- An Enterprise license is a signed license you install directly, with no callout — suited to air-gapped deployments.
DioscHub reads the current tier at startup and re-checks it on a daily schedule; the resolved tier is what drives the entitlements above.
