What is FuseBase?

FuseBase (formerly Nimbus) is an AI workspace platform for building secure client portals, internal workspaces and AI agents in one place. It combines a drag-and-drop page builder, knowledge base, built-in CRM, e-signatures, forms and file sharing with white-label client-facing portals. Teams use it to centralise documents, automate workflows and collaborate with external clients and partners through branded hubs. The platform offers a free tier alongside paid plans and a custom enterprise option.

Pros & cons

Advantages

  • Combines internal workspaces and external client portals in a single tool, reducing the need for separate apps.
  • Free tier and a one-code AppSumo lifetime deal make it accessible for solo users and small teams to try.

  • Strong security and compliance posture, including SSO, 2FA, encryption, HIPAA and SOC 2 Type II support.
  • Broad feature set covering CRM, e-signatures, forms, transcription and automation in one subscription.

Limitations

  • The wide range of features and AI request, portal and automation limits can take time to learn and configure.
  • Per-month pricing rises steeply between tiers, from 32 dollars for Solo to 332 dollars for Advanced.
  • Unlimited portals, clients and the top Unlimited plan require contacting sales rather than self-serve checkout.
  • No dedicated desktop or mobile apps are highlighted on the homepage, with the focus on web access and browser extensions.
