FuseBase

FuseBase (formerly Nimbus Platform, rebranded around 2022) is a client collaboration platform that fuses portals, wiki-style documentation, and project management into one workspace. Originally built as a note-taking and knowledge management tool, it has evolved into a full client portal product aimed at agencies, consultancies, and service teams that need to share structured content alongside project updates.

Super Docs and the content editor

FuseBase's standout feature is its "Super Docs" format — rich documents that go well beyond plain text. Inside a single page you can embed task boards, databases, file galleries, whiteboards, YouTube videos, Figma frames, and more. This makes FuseBase particularly capable for agencies that want to deliver onboarding guides, SOPs, or project dashboards without stitching together multiple tools. The editor is block-based and fairly polished on desktop; it handles nested pages and linked databases in a way that feels closer to Notion than to a traditional client portal.

Client portals

Portals in FuseBase are essentially curated views of your workspace — you select which pages and sections a client can see, then share a portal link. Each client gets their own space with scoped access. Branding options include custom logos and colors; a custom domain requires a higher-tier plan, as does full white-labeling (removing FuseBase branding entirely).

Clients can comment, fill out forms, complete tasks, and upload files directly in the portal without needing a full FuseBase account. Guest access is managed via invite or shareable link.

AI features

FuseBase has integrated an AI assistant that can generate content, summarize pages, and answer questions by searching across your workspace. It's useful for quickly drafting client-facing documentation but sits behind paywalls on the free tier.

Pricing

FuseBase offers a free plan that covers basic portals and a limited number of workspaces — workable for freelancers with a handful of active clients. Paid plans start at around $9 per user per month on the Solo tier, while team-oriented plans begin at approximately $82 per month, which bundles more portals, higher storage limits, and collaboration features. White-label and custom domain support are gated to the upper tiers.

The pricing structure can feel fragmented: portal limits, AI credits, and storage are all separate constraints, and it takes some reading to understand exactly what you get at each level.

Integrations

FuseBase connects to Zapier for workflow automation and supports OAuth sign-in with Google. Embedded content from third-party tools (Google Drive, Loom, Figma, YouTube) works well inside Super Docs. Native integrations with CRMs or project management platforms are limited — Zapier is the primary bridge to external tools.

Limitations

FuseBase can feel over-engineered for teams that just need a simple branded portal to share files and collect approvals. The platform's breadth — databases, wikis, whiteboards, tasks — creates real cognitive overhead during setup. The mobile apps lag noticeably behind the desktop experience, which matters if clients frequently access portals from their phones. White-labeling being locked to higher-tier plans is a recurring complaint from agencies evaluating the tool.

Who it suits

FuseBase is a good fit for knowledge-heavy service businesses: consulting firms delivering structured deliverables, training companies sharing course materials alongside project updates, or agencies that want their client portal to double as an internal knowledge base. Teams with simpler needs — file sharing, status updates, e-signatures — will likely find it more tool than necessary.

Note: The scraped source material was a GoDaddy-parked domain serving unrelated content — no live product pages were available. This review draws on training knowledge of FuseBase. Pricing figures should be verified against the current FuseBase website before publishing.
