What is FuseBase?
FuseBase is a client-portal and collaboration platform with a page builder, files, tasks and forms. Organisations can put portals on their own domain, brand sign-in and emails, use custom SMTP, and give each client a separately styled portal with no FuseBase marks.

◎ Community Signals
See what customers and users say about the software's white-label experience:
Buyers on Capterra and G2 praise FuseBase (formerly Nimbus) for client portals that look like yours, your own website address (custom domain / CNAME), and CSS/HTML customization with white labeling. Agencies and solopreneurs say a branded, adaptable client experience builds trust. A few reviewers want more built-in styling options, fuller branded email, or clearer custom-domain setup without needing support.
| White-label strengths |
Considerations |
| Branded client portals described as looking professional and helping win or impress clients |
Some want more options to match the portal to their company’s look and style |
| Custom domain / CNAME called out as a standout feature for sharing branded spaces |
Custom-domain setup can be confusing until support walks you through it |
| Logo, favicon, and per-organization branding reported on public notes / workspaces |
Older Reddit feedback: inviting a client to create an account could still open on the vendor’s website address, which confused guests |
| CSS/HTML customization and white labeling praised for matching each client’s brand |

What this means for buyers
Buyers mainly talk about FuseBase as a login space for your clients that can carry your logo, sit on your website address, and be styled with CSS/HTML so it matches your brand. Before you invite clients, check three things in a live account: does the invite and login stay on your website address, do emails look like they come from you, and how much of the vendor’s name still shows?
Buyer fit
Agency
Core question: Can I operate and adapt it as my own offering for multiple customers?
Reviewers running agencies and consultancies say branded portals, white labeling, and per-client hubs improve how clients see them and support delivering services under their own brand. Confirm multi-client branding and setup time in the product itself.
No-Code Entrepreneur
Core question: Can I present the software as my own?
Many reviewers highlight custom domain / CNAME, branded public pages, and white labeling. Plan a support call if DNS or CSS setup is new to you, and check whether emails are fully under your brand.
Reseller
Core question: Can I sell and package the software as my own offering for customers?
Public comments are about agencies and coaches using FuseBase with their clients. They do not describe reselling finished branded copies of FuseBase as a product line to other businesses.
