Document360 vs FuseBase: Which Is Better?
Knowledge base and client wiki platforms compared.

Document360 and FuseBase solve related but distinct problems: Document360 is a dedicated knowledge base platform built around structured documentation and self-service support, while FuseBase (formerly Nimbus Platform) is a client collaboration hub that combines internal wikis, client portals, and project workspaces. If you need a polished help center or API docs site, they're in different leagues — but both get compared when teams search for a place to organize and share knowledge with clients.
Quick comparison

| Best for | SaaS support teams, technical writers | Agencies, consultants, client-facing teams |
| Free tier | Yes (limited) | Yes (limited) |
| Paid plans start at | ~$149/month (workspace-based) | ~$9/user/month |
| AI features | Strong (writing, search, chatbot) | Basic |
| White-label | Yes (custom domain on all paid plans) | Yes |

Document360
Document360 is a purpose-built knowledge management platform with serious depth. Its content model is built around structured article hierarchies, categories, and projects — meaning your documentation actually has architecture, not just a flat pile of pages.
Editor options are a genuine differentiator. You get both a WYSIWYG rich-text editor and a Markdown editor with live preview, letting technical and non-technical writers work in the same system without friction. You can also embed content blocks, create decision trees for step-by-step troubleshooting flows, and use conditional content to show or hide sections based on reader group, device, country, or date.
AI runs through the whole platform. The AI Writing Agent can generate articles from prompts, uploaded videos, audio files, or text documents. AI search delivers ChatGPT-style contextual answers rather than a list of links. There's also auto-glossary generation, duplicate content detection, and an AI-powered support chatbot trained on your documentation. Document360 claims this can deflect 30% of inbound support tickets.
Workflow and governance are strong for teams: custom review workflows with role-based assignments, audit trails, version history with diff comparisons, and a feedback manager that surfaces what readers are thumbs-downing. The Pro Analytics dashboard shows search analytics (what people searched for and didn't find), broken link detection, and reader engagement patterns.
Pricing is workspace-based rather than per-seat, which matters for large teams. The Free plan covers basic documentation. Startup runs roughly $149/month (billed annually) and covers one project with a small team. Business (~$299/month) adds custom workflows, embedded help center, PDF import, and 30+ integrations. Professional (~$599/month) unlocks AI search, dedicated account managers, and advanced analytics. Enterprise is custom-quoted and adds SSO with Okta/Entra ID/ADFS, staging environments, security audit trails, and IP restriction.
Limitations: Document360 is not a client portal — there's no concept of per-client workspaces, task management, or real-time collaboration on documents with external parties. It's documentation software, not project collaboration software. The pricing also gets steep fast if you need multiple knowledge base projects.
FuseBase
FuseBase (which rebranded from Nimbus Platform in 2023) approaches knowledge management from the opposite direction: it's primarily a client collaboration platform that also does internal wikis. The organizing concept is the workspace — a shared environment where you, your team, and your clients can interact around documents, tasks, and files.
Client portals are where FuseBase earns its place. You can spin up a white-labeled portal for each client with custom branding, giving clients a dedicated space to view project updates, access deliverables, leave comments, and track progress. This is fundamentally different from Document360's model, where "readers" are mostly passive consumers of documentation.
Super documents are FuseBase's content primitive — flexible pages that can mix text, tables, embedded files, tasks, databases, and media in a single canvas. This makes them versatile for proposals, onboarding guides, status reports, and SOPs, though the flexibility can make the output feel less structured than Document360's article-centric model.
Internal wiki functionality covers team knowledge bases, meeting notes, and project documentation. The search works across all workspaces. Version history is present but less sophisticated than Document360's diff-level comparison.
Pricing is per-user, which is friendlier for small teams. A free plan exists with limited features. Team plans run around $9/user/month (billed annually), while Business plans with more storage, guest access, and integrations land around $18/user/month. Enterprise pricing is custom. Guest/client access is typically available at no extra charge or reduced rates, which matters if you're adding many external collaborators.
Limitations: FuseBase isn't optimized for public-facing documentation. It lacks Document360's SEO controls, API documentation tools, translation pipeline, and support chatbot capabilities. If you need a help center that shows up in Google, FuseBase isn't the right tool. AI features are also considerably thinner than Document360's full AI writing suite.
When to choose Document360
- You're building a customer-facing help center or knowledge base that needs to be searchable, SEO-optimized, and embeddable in your product
- You have a technical writing team that needs structured workflows, review cycles, and version governance
- You need API documentation or developer docs alongside user guides
- Ticket deflection from a documentation-driven chatbot is a measurable goal
- You need to publish in multiple languages at scale
- Your audience is primarily reading, not collaborating
When to choose FuseBase
- You're an agency or consultant who needs per-client collaboration spaces, not a public knowledge base
- You want to share project updates, proposals, and deliverables with clients in a branded portal they can actually interact with
- Internal team wikis and client-facing portals need to live in the same tool
- Per-user pricing fits your budget better than workspace-based pricing
- Your team collaborates heavily on document creation rather than publishing finished articles
Bottom line
These tools only compete if you squint. Document360 is the clear choice for any team that needs a proper knowledge base — structured, searchable, SEO-ready, with AI-assisted authoring and analytics to match. FuseBase is better suited to service businesses that need to manage client relationships through shared workspaces and don't need public-facing documentation.
If your main deliverable is a help center or self-service documentation site, Document360 wins on depth and feature maturity. If your main deliverable is client work and you need a portal to deliver it through, FuseBase (or a more dedicated client portal tool) is the more natural fit. Using Document360 as a client portal would be awkward; using FuseBase as a public knowledge base would be a stretch.
