Multi-Tenant B2B: Junyr vs Alternatives

If you're building a B2B SaaS or managing multiple clients, you need multi-tenant infrastructure. This article compares how Junyr, n8n, Make, and Zapier handle multi-tenancy, and why Junyr is designed for B2B from day one.

TL;DR: Multi-Tenant Comparison

Verdict: Junyr is the only platform with native multi-tenant B2B architecture.

1. What Is Multi-Tenancy?

Single-Tenant vs Multi-Tenant

Single-Tenant:

• 1 account = 1 user or 1 company
• Each user/company has a separate database or instance
• Example: You manage 10 clients → You need 10 separate accounts

Multi-Tenant:

• 1 platform supports multiple companies (tenants)
• Shared infrastructure with data isolation
• Example: You manage 10 clients → 1 admin account manages all 10 companies

Why Multi-Tenancy Matters for B2B

If you're:

• Agency managing automation for 10+ clients
• Consultant deploying agents for multiple companies
• SaaS provider white-labeling automation

You need multi-tenancy to:

• Centralize management (1 admin account)
• Isolate data (client A can't see client B's data)
• Scale efficiently (add new clients without new infrastructure)

2. Junyr: Native Multi-Tenant Architecture

Company-Based Model

Junyr is designed as a multi-tenant B2B SaaS from day one:

Platform Admin (Super Admin)
├── Company A (Acme Inc)
│   ├── User 1 (john@acme.com) - Company Admin
│   ├── User 2 (jane@acme.com) - User
│   ├── Agent 1 (sales@acme.com) - Max (Sales)
│   ├── Agent 2 (support@acme.com) - Emma (Support)
│   └── Domains: acme.com, acme.fr
├── Company B (TechCorp)
│   ├── User 1 (sarah@techcorp.com) - Company Admin
│   ├── User 2 (bob@techcorp.com) - User
│   ├── Agent 1 (sales@techcorp.com) - Sophie (Sales)
│   └── Domains: techcorp.com
└── Company C (StartupZ)
    ├── User 1 (founder@startupz.io) - Company Admin
    └── Agent 1 (hello@startupz.io) - Alex (General Assistant)

Key Features

1. Company Domains

• Each company can add verified domains (acme.com, techcorp.com)
• Email addresses use company domains (sales@acme.com, not sales@junyr.app)

2. Auto-Registration

• New users with @acme.com email automatically join Acme Inc company
• No manual invitation needed (domain verification required)

3. User Roles

4. Data Isolation

• PostgreSQL Row-Level Security (RLS)
• Each query automatically filtered by company_id
• User A (Company A) cannot see User B's data (Company B)

5. Shared Agents

• All users in Company A can use Agent 1 (Max)
• Agent ownership: Agent created by User 1 → visible to all Company A users

3. n8n: Manual Multi-Tenancy (Self-Built)

The Challenge

n8n is not designed for multi-tenancy. You must build it yourself.

Options:

Option A: Multiple n8n Instances (Separate Databases)

Architecture:

Company A: n8n instance + PostgreSQL DB (separate server)
Company B: n8n instance + PostgreSQL DB (separate server)
Company C: n8n instance + PostgreSQL DB (separate server)

Cost: 3 companies × €50/month (server) = €150/month = €1,800/year

Management: Manual setup, separate backups, separate updates

Option B: Single n8n Instance with Manual Data Isolation

Architecture:

1 n8n instance + 1 PostgreSQL DB
├── Workflow 1 (tagged "company_a")
├── Workflow 2 (tagged "company_b")
└── Workflow 3 (tagged "company_c")

Challenge:

• No native company isolation
• Must manually tag workflows with company_id
• Risk of data leakage (Workflow 1 accesses Company B data by mistake)
• No auto-registration (must invite users manually)

Development time: 3-6 weeks to build multi-tenant logic

---

4. Make & Zapier: No Multi-Tenancy (Per-Account Model)

The Problem

Make and Zapier use a per-account model:

• Each user or company = separate account
• No data sharing between accounts
• No centralized management

Real Example: Managing 10 Clients

Scenario: You're an agency managing automation for 10 clients.

With Make/Zapier

Option A: 1 account for all clients

Your Account
├── Scenario 1 (Client A: Sales automation)
├── Scenario 2 (Client B: Invoice processing)
├── Scenario 3 (Client C: Lead qualification)
└── ... (10 clients mixed together)

Problems:

• All clients' data mixed in 1 account
• No data isolation (risk of Client A seeing Client B's data)
• Difficult to manage (100+ scenarios)
• Clients can't access their own dashboards

Option B: 10 separate accounts (1 per client)

Account 1 (Client A) - €9/month
Account 2 (Client B) - €9/month
Account 3 (Client C) - €9/month
...
Account 10 (Client J) - €9/month

Cost: 10 accounts × €9/month = €90/month = €1,080/year

Management: Must log into 10 different accounts to manage scenarios

Billing: 10 separate invoices/month (nightmare for accounting)

With Junyr

1 account for all clients:

Your Admin Account
├── Company A
│   ├── User: client_a@company-a.com
│   └── Agents: Max (Sales), Sophie (Accounting)
├── Company B
│   ├── User: client_b@company-b.com
│   └── Agents: Emma (Support)
└── Company C
    ├── User: client_c@company-c.com
    └── Agents: Alex (General Assistant)

Cost: Plan SME (10 companies/agents)

Management: 1 admin dashboard to manage all 10 companies

Billing: 1 invoice/month

Advantage: €1,080 (Make) vs Junyr SME plan = significant savings

6. Real Use Case: Agency Managing 10 Clients

Scenario: Automation Agency

Objective: You manage automation for 10 B2B clients.

With Junyr (Multi-Tenant)

Setup (one-time, 2 hours):

1. Create 10 companies in Junyr admin panel
2. Add verified domains for each client (client1.com, client2.com)
3. Recruit agents for each client (Sales, Support, Accounting)
4. Invite client users via email (auto-join via domain)

Cost:

• Junyr SME plan (10 agents)
• Annual: Plan SME x 12 months

Management:

• 1 admin dashboard to manage all 10 clients
• Each client has isolated data (can't see other clients)
• Clients access their own dashboard via client1.com domain

Result: Simple, centralized, cost-effective.

With Make (Per-Account)

Setup (one-time, 10-20 hours):

1. Create 10 separate Make accounts (1 per client)
2. Build workflows for each client separately
3. Configure Gmail/HubSpot for each client (10 × 1 hour = 10 hours)

Cost:

• 10 Make accounts × €9/month = €90/month
• 10 Gmail accounts × €5.75 = €57.50/month
• Total: €147.50/month
• Annual: €147.50 × 12 = €1,770/year

Management:

• Must log into 10 separate Make accounts
• 10 separate billing invoices/month
• No centralized dashboard

Result: Complex, expensive, time-consuming.

Difference: €1,770 (Make) vs Junyr SME plan = significant annual savings

7. Domain Verification & Auto-Registration

Junyr's Domain System

How it works:

1. Company admin adds domain (acme.com)
2. Verify ownership (DNS TXT record or email code)
3. Domain approved → Automatic benefits:
   • New users with @acme.com auto-join Acme Inc company
   • Agents can use sales@acme.com (instead of sales@junyr.app)
   • Full white-label branding

Example:

Day 1: Admin creates "Acme Inc" company
Day 2: Admin adds domain "acme.com" → Verifies via DNS
Day 3: New employee joins: john@acme.com → Auto-joins Acme Inc
Day 4: Agent email: sales@acme.com (professional branding)

Result: Zero-friction onboarding for new company users.

Competitors: No Auto-Registration

• Make/Zapier: Must manually invite each user (no domain-based auto-join)
• n8n: Must build domain verification system yourself (3-6 weeks dev)
