Your client asks for “that file from last month”. You check Google Drive, then Slack, then your email, then that Notion page you forgot to share. Ten minutes gone, and you still look disorganized.
FuseBase wants to be the one place where that never happens. It’s a workspace for your team, branded client portals for your customers, AI agents that do busywork, and now even hosting for tools like n8n, all under one login.
The FuseBase lifetime deal is back on AppSumo at $79 per code, and it’s #1 in Project Management. It also has a long and complicated history on AppSumo, so we read the reviews carefully (all 606 of them) before telling you whether it’s worth it this Black Friday.

First, a quick history lesson
You’ll see FuseBase has 606 reviews, but 395 of them are from 2020, when it was Nimbus Note, a popular Evernote alternative. Since then it rebranded, rebuilt the product and moved toward client portals, AI agents and apps.
That matters for you because some long-time users are unhappy: they bought a note-taking app and now have something very different. If you just want a simple Evernote replacement, this probably isn’t it anymore. If you want a client-facing workspace with AI, keep reading.
What FuseBase actually does for you
1. Branded client portals
This is the star feature. You create a white-labeled space for each client with their documents, tasks, deliverables, approvals and conversations. One agency said that drafts, feedback and approvals used to be spread across emails, chats and shared drives, and now everything sits in one portal under their own brand. You can also use portals as deal rooms or simple SEO-friendly sites.
2. A team workspace and knowledge base
Drag-and-drop pages with tables, PDFs, images and embeds from Figma, Miro and Looker Studio. AI helps you draft, summarize and find answers across all your content. Documents now use Markdown, which makes it easier for AI to create and update them.
3. AI agents and automations
Every plan includes AI agents, AI requests, automation credits and video/audio transcription hours. You can also build your own apps with tools like Claude Code, Cursor or VS Code, using your existing AI subscription instead of paying FuseBase for tokens. APIs and an MCP server connect everything.
4. Hosted n8n, Firecrawl and Paperclip
FuseBase can host and maintain popular open-source tools for you: Paperclip (AI agents, branded “FuseBase Work”), n8n (automation) and Firecrawl (web data). Be aware: AppSumo’s own graphic shows these need 10, 15 and 20 stacked codes respectively. That’s $790 to $1,580, not $79.
The good stuff (what buyers love)
- Everything is connected. Pages, apps, automations, databases, portals and AI agents all work together, which reviewers call a big plus.
- Client experience. Agencies say clients always know where to find things, and the portals look professional under their own brand.
- Very active development. The founder says the team’s output has grown about 5x in a year, and recent reviewers are impressed by how much keeps shipping.
- Stack as much as you need. Unlimited code stacking, and every code past 10 adds more members, storage and portals.
- Security options. SOC 2 and HIPAA are listed in the plan features, which is rare for an AppSumo deal.
The not-so-good stuff (read this before you buy)
FuseBase has 56 reviews at 3 stars or below, more than any other deal we have covered this Black Friday. Here’s what keeps coming up:
- Support complaints. Several buyers in 2026 said booked demo calls were missed or cancelled, and one felt AppSumo buyers were treated as second-class customers. Others praise the team, so experiences vary, but don’t count on a personal onboarding call.
- Steep learning curve. Even a technical buyer called it “a very complicated product”. Tutorials explain features, not real-world setups.
- Things change a lot. One reviewer said features can appear and disappear without notice while the platform is rebuilt.
- Mobile apps lag behind. Users want up-to-date Android and iOS apps and a real Windows desktop app, and one said clients got “not compatible” errors on some phones.
- Old Nimbus fans feel left behind. The note-taking side gets few improvements now.
- A postponed promise. The founder openly said reselling the apps you build is delayed to 2027.
Is the FuseBase lifetime deal worth it? Let’s do the math
Here’s what FuseBase charges on its official pricing page, next to the most useful AppSumo options:
| Plan | Users | Portals / clients | AI requests | Price |
|---|---|---|---|---|
| Solo (direct) | 1 | 1 / 1 | 1,000 | $32/month |
| Essentials (direct) | 5 | 10 / 100 | 10,000 | $82/month |
| AppSumo 1 code | 1 | 1 / 5 | 1,000/mo | $79 once |
| AppSumo 3 codes | 10 | 15 / 75 | 10,000/mo | $237 once |
So the FuseBase lifetime deal pays for itself in about 3 months either way. One code roughly matches the Solo plan. Three codes give you more users and portals than Essentials, with the same AI requests. You also get 50 to 200 workspaces and 50 to 400 GB of storage depending on how many codes you stack.
Which option? 1 code if you’re solo with one client portal. 3 codes is the sweet spot for a small agency. Only go to 10+ codes if you really want the hosted tools and white labeling at scale. Small print in the FuseBase lifetime deal terms: redeem codes within 60 days, and previous Nimbus Note buyers keep their old limits but can stack more codes.
Should you grab the FuseBase lifetime deal this Black Friday?
Yes, if you…
- run an agency or consultancy and want branded client portals
- are paying for Notion plus a separate portal tool and want one system
- like building your own tools with Claude Code or Cursor
- are patient enough to learn a powerful but complex platform
Skip it if you…
- just want a simple note-taking or Evernote-style app
- need polished mobile apps for you or your clients
- need hand-holding and quick personal onboarding
- want something stable that won’t change much month to month

My honest take
FuseBase is one of the most ambitious products on AppSumo: client portals, a knowledge base, AI agents, an app builder and hosted tools in one place. Recent reviewers who use it for client work are genuinely happy. But it’s also complex, it changes fast, and the support complaints are real.
My advice: start with 1 code, build one real client portal in your first two weeks, and see if your client actually uses it. If it clicks, stack more codes. If it feels like too much, use the 60-day refund. That way the FuseBase lifetime deal is low risk instead of a $300 gamble.
FAQs
Is FuseBase the same as Nimbus Note?
It’s the same company, rebranded. The product has changed a lot and now focuses on client portals, AI agents and apps rather than note-taking.
How many codes do I need?
One code works for a solo user with one portal. Three codes suit most small teams. Hosted Paperclip, n8n and Firecrawl need 10, 15 and 20 codes.
Does FuseBase have mobile apps?
Yes, but several reviewers say the Android and iOS apps are behind the web version, so test them on your devices first.
Can I get a refund?
Yes. AppSumo gives you 60 days to request a refund on the FuseBase deal.
