Pros & Cons
Langdock
Pros

- SSO, SCIM and SAML are included even on the entry Core plan.
- Non-technical staff can build no-code agents with their own knowledge bases and permissions.

Cons

- Building advanced agents has a learning curve.
- Per-seat pricing with Max seat upgrades and workflow add-ons can get expensive for small teams.
