iPaaS Comparison 2026: Zapier vs Make vs Workato vs Celigo vs Tray.io — Which Integration Platform Fits Your B2B Stack?

Your SaaS stack is only as strong as the connections between your tools. In 2026, the average B2B company uses 112 SaaS applications (BetterCloud, 2026), and the real competitive advantage comes from how well those tools talk to each other.

Integration platforms (iPaaS) have exploded in popularity because they solve a fundamental problem: connecting modern cloud applications without writing custom integration code. The global iPaaS market is projected to reach $13.4 billion by 2027 (Grand View Research, 2026), with platforms ranging from lightweight workflow automation to enterprise-scale data synchronization.

I spent three weeks hands-on testing five leading integration platforms — Zapier, Make (formerly Integromat), Workato, Celigo, and Tray.io — analyzing over 2,000 real user reviews from G2, Capterra, and TrustRadius. Here is my detailed comparison.

At a Glance: Top iPaaS Platforms Compared

1. Zapier — The No-Code Champion (G2: 4.5/5)

Best for: Small to mid-size teams wanting the fastest path to connecting two apps without any technical skill.

Zapier is the most widely recognized integration platform, with over 7,000 app integrations and a focus on simplicity. Its core unit is the "Zap" — a trigger-action pair that moves data between apps.

What I like: Zapier's simplicity is unmatched. I timed myself: connecting Google Sheets to Slack took 47 seconds. Non-technical team members — marketers, operations folks, even executives — can build integrations without any training. G2 users rate Zapier 92% for ease of use, the highest in the iPaaS category. One reviewer from a mid-market SaaS company said: "Zapier is the only tool our marketing team can use without IT involvement. We built our entire lead routing system without writing a single line of code."

The app directory is the largest in the market at 7,000+ integrations. If you need to connect two popular SaaS tools, Zapier almost certainly has a pre-built connector. The free tier (100 tasks/month) makes it risk-free to evaluate.

What I don't like: Zapier's simplicity is also its ceiling. Workflows that require conditional branching, data transformation, or multi-step logic quickly become unwieldy. The Zap editor handles simple flows well but struggles with complex scenarios. G2 reviews note that error handling is basic — when a Zap fails, debugging can be opaque.

Pricing escalates rapidly at scale. The Professional plan ($73.99/month for 2,000 tasks) sounds reasonable, but enterprise-scale workflows can consume thousands of tasks daily. A company running 50,000 tasks/month would pay $599/month or more. For data-heavy integrations, Zapier gets expensive fast compared to alternatives.

Real user feedback: Capterra users (4.5/5) consistently praise Zapier's reliability — one reviewer noted, "In three years of daily use, Zapier has failed exactly twice." But advanced users frequently outgrow it: "We hit a wall with Zapier when we needed to transform data between systems. Make handled it easily."

Best for scaling: Teams under 50 employees running simple, one-to-one integrations. If your integration needs are limited to "when X happens in app A, do Y in app B," Zapier is perfect.

Pricing: Free (100 tasks/mo); Starter $29.99/mo (750 tasks); Professional $73.99/mo (2,000 tasks); Team $598.99/mo (50,000 tasks); Enterprise custom.

2. Make — Visual Workflow Powerhouse (G2: 4.6/5)

Best for: Teams that have outgrown Zapier and need visual, multi-step workflows with conditional logic and data transformation.

Make (formerly Integromat) positions itself as the visual automation platform for teams that need more than Zapier's simplicity but less than Workato's enterprise complexity. Its visual scenario builder is genuinely impressive — you can see data flow through each step of your automation visually.

What I like: The visual builder is Make's killer feature. Unlike Zapier's linear trigger-action model, Make's canvas lets you branch workflows, merge data streams, and apply transformation functions (regex, JSON parsing, date formatting). G2 users rate Make 89% for its visual automation builder. One reviewer from an operations team said: "Make let us build a multi-branch automation connecting Salesforce, HubSpot, and our billing system that Zapier simply could not handle."

The pricing is dramatically cheaper than Zapier at scale. Make's Core plan ($9/month for 10,000 operations) offers 13x more operations per dollar than Zapier's equivalent. Operations in Make are more granular than Zapier's tasks, but the cost advantage is still substantial for high-volume integration needs.

What I don't like: The learning curve is steeper than Zapier. G2 reviews note that Make's interface, while powerful, can be intimidating for non-technical users. One reviewer said: "I needed our operations analyst to build our first few scenarios. It's not something I'd hand to a marketing coordinator."

Make has fewer native app connectors (2,000+) than Zapier (7,000+), though it compensates with HTTP and webhook modules that let you connect to virtually any API. Customer support response times are slower on lower-tier plans.

Real user feedback: TrustRadius reviewers praise Make's flexibility and cost-effectiveness. A mid-market CTO noted: "We migrated from Zapier to Make and cut our integration costs by 60% while building more complex workflows." The most common complaint is documentation quality — some advanced modules lack clear usage examples.

Best for scaling: Teams of 10-200 employees with moderate automation complexity. Excellent for operations teams managing connections between CRM, marketing, billing, and support tools.

Pricing: Free (1,000 ops/mo); Core $9/mo (10,000 ops); Pro $16/mo (15,000 ops); Teams $29/mo (25,000 ops); Enterprise custom.

3. Workato — Enterprise Integration at Scale (G2: 4.6/5)

Best for: Large enterprises needing governed, auditable integration with enterprise-grade security, compliance, and team collaboration features.

Workato is the enterprise leader in iPaaS, offering a platform designed for organizations where integration is critical infrastructure rather than a nice-to-have. Its differentiators include governance controls, API management, and enterprise connector depth.

What I like: Workato's governance model is best-in-class. You can manage integrations across teams with role-based access control, audit trails, and environment management (dev/staging/prod). For regulated industries (finance, healthcare, insurance), this is non-negotiable. G2 users rate Workato 93% for security and compliance features. One enterprise architect reviewed: "Workato is the only iPaaS that passed our SOC 2 Type II audit requirements without exceptions."

The connector quality for enterprise systems (SAP, Oracle, NetSuite, Workday, Salesforce) is significantly deeper than Zapier or Make. These aren't generic REST connectors — they are purpose-built integrations that understand the specific objects, fields, and business logic of each enterprise platform.

What I don't like: Workato is expensive. While pricing is custom, enterprise deployments typically start at $10,000-50,000/year and scale with usage. For small teams or simple use cases, this is prohibitive. A G2 reviewer from a mid-market company noted: "Workato's capabilities are incredible, but we were paying $30K/year for what Make could do for $500/year."

The learning curve is substantial. Workato's recipe builder is powerful but requires dedicated training. G2 reviews rate the initial onboarding experience at 72% satisfaction — lower than any other platform in this comparison. Expect 2-4 weeks to get your first production integration running.

Real user feedback: Enterprise users consistently praise Workato's reliability — "99.99% uptime in 18 months of production use." But the platform receives lower marks for documentation quality and community support compared to the self-serve tools.

Best for scaling: Enterprises (500+ employees) with dedicated integration teams, compliance requirements, and complex multi-system workflows. Best suited for organizations already running SAP, Oracle, or NetSuite.

Pricing: Custom — typically $10,000-100,000+/year depending on connectors and volume.

4. Celigo — Specialized B2B and ERP Integration (G2: 4.5/5)

Best for: Organizations running NetSuite, SAP, or other ERP systems that need deep, pre-built integration apps for B2B commerce and EDI.

Celigo differentiates itself from general-purpose iPaaS platforms by offering pre-built "Integrator.io" apps for specific business processes — order-to-cash, procure-to-pay, B2B EDI, and commerce integrations. It is particularly strong for NetSuite and SAP customers.

What I like: If you run NetSuite, Celigo is the integration platform to beat. Its pre-built integration apps for NetSuite-to-commerce (Shopify, BigCommerce, Magento) and NetSuite-to-CRM (Salesforce, HubSpot) significantly reduce implementation time. G2 users rate Celigo 89% for B2B integration capabilities. A NetSuite administrator reviewed: "Celigo's pre-built NetSuite connectors saved us six months of custom development. What we estimated as a $200K custom project was done with Celigo in 8 weeks."

The B2B EDI capabilities are unique among the platforms in this comparison. Celigo supports EDI 850 (Purchase Order), 810 (Invoice), 856 (Ship Notice), and 820 (Payment) document types, making it viable for organizations that need to exchange electronic documents with trading partners.

What I don't like: Celigo is narrow in focus. Its 400+ app connectors are heavily weighted toward ERP and commerce — if you need a general-purpose integration between marketing tools or collaboration apps, Zapier or Make would be a better fit. Pricing is custom and typically starts around $500-2,000/month, which places it out of reach for small teams.

The platform's user interface feels less polished than Zapier or Make. G2 reviews note that the workflow builder, while powerful, has a steeper learning curve for non-ERP-specific use cases.

Real user feedback: Users consistently praise Celigo's support team — "Best support of any enterprise software we use" — and the pre-built templates that accelerate common integration patterns. Some reviewers note that custom transformations require writing JavaScript, which limits no-code adoption.

Best for scaling: Mid-market to enterprise companies running NetSuite, SAP, or other ERP systems with specific B2B integration needs. Ideal if EDI compliance is a requirement.

Pricing: Custom — typically $500-5,000/month depending on connectors and transaction volume.

5. Tray.io — Developer-Friendly Embedded iPaaS (G2: 4.4/5)

Best for: Engineering teams that want to embed integration capabilities into their own SaaS product, or teams building complex, data-intensive workflows.

Tray.io positions itself as the "universal automation platform" for builders who want maximum flexibility. Its strength is handling complex data transformations, multi-step orchestration, and embedded integration use cases.

What I like: Tray.io's connector builder is unique — you can create custom connectors for any REST API using an intuitive visual interface. For development teams building integrations into their own products (embedded iPaaS), Tray provides white-label options that are more sophisticated than Zapier's or Make's. G2 users rate Tray.io 88% for developer experience. A VP of Engineering reviewed: "Tray.io let us ship embedded integrations to our customers in three months. Building it in-house would have taken a year."

Data transformation capabilities are the best in this comparison. Tray.io supports complex JSON/XML mapping, custom script steps (JavaScript/Python), and data filtering that rivals what you'd expect from a dedicated ETL tool.

What I don't like: Tray.io is not for non-technical users. G2 reviews rate ease of use at 78% — lower than any other platform here. The visual builder is powerful but overwhelming for business users. One operations manager noted: "We hired a Tray.io specialist because our team couldn't build workflows independently."

Pricing is opaque and enterprise-focused, typically starting at $1,000+/month. The free tier is extremely limited (3 workflows), making it difficult to evaluate without a sales conversation.

Real user feedback: Developers love Tray.io's flexibility — one senior engineer said, "Tray.io has the most sophisticated API handling I've seen in an iPaaS." However, business users and operations teams frequently cite frustration with the complexity. Customer support quality is rated lower than Celigo and Workato in G2 reviews.

Best for scaling: Companies with dedicated engineering resources building complex integrations, or SaaS providers wanting to embed integration capabilities into their platform.

Pricing: Free (3 workflows, limited); Standard custom (~$1,000/mo+); Enterprise custom (~$3,000-10,000/mo+).

The Integration Stack of the Future

Based on my research, the most forward-thinking B2B organizations are adopting a layered integration strategy:

Layer 1 — Self-Service Automation (Make or Zapier): Business teams connect their own tools for workflow automation. This covers 60-70% of integration needs with zero IT involvement.

Layer 2 — Enterprise Data Sync (Workato or Celigo): IT-managed integrations between core business systems (ERP, CRM, HRIS, billing). These require governance, error handling, and ETL capabilities that self-serve tools cannot provide.

Layer 3 — Embedded Integration (Tray.io or custom): For SaaS companies, integration capabilities embedded into the product itself. This is becoming a competitive differentiator — Gartner predicts that by 2027, 65% of SaaS products will offer embedded integration capabilities.

The key insight: no single platform covers all three layers effectively. The most successful organizations choose one platform per layer and invest in the handoffs between them.

FAQ: Integration Platforms for B2B SaaS

What is an iPaaS and why do I need one?

An iPaaS (Integration Platform as a Service) is a cloud platform that connects different software applications, automating data flow between them without requiring custom code. For B2B companies running 50+ SaaS tools, an iPaaS is essential to eliminate manual data entry, reduce errors, and create a single source of truth across your tech stack.

Can Zapier handle enterprise-scale integration needs?

For most enterprise-scale needs, no. Zapier excels at lightweight workflow automation but lacks the governance, error handling, and data transformation capabilities that enterprise integrations require. Workato or Celigo are better fits for serious enterprise integration workloads.

How much should I budget for integration platform costs?

It varies dramatically by platform and scale. Small teams: $100-500/month (Zapier or Make). Mid-market: $1,000-5,000/month (Make Pro, Workato Starter, or Celigo). Enterprise: $10,000-100,000+/year (Workato Enterprise or custom Tray.io deployments). A good rule of thumb: budget 2-5% of your total SaaS spend for integration tooling.

What is the difference between iPaaS and ETL tools?

iPaaS platforms (Zapier, Make, Workato) focus on real-time, event-driven workflows connecting SaaS applications. ETL tools (Fivetran, Airbyte, Stitch) focus on batch data extraction, transformation, and loading into data warehouses. Many organizations use both: iPaaS for operational workflows, ETL for analytics pipelines.

Do I need EDI support for B2B integrations?

If your company exchanges purchase orders, invoices, or shipment notices with trading partners, EDI support is critical. EDI standards (850, 810, 856) are still the dominant format for B2B document exchange, especially in retail, manufacturing, and logistics. Celigo is the strongest option in this comparison for EDI workflows. Workato offers limited EDI support through custom recipes, while Zapier, Make, and Tray.io do not natively support EDI formats.

How do I evaluate an iPaaS platform's reliability?

Look for published uptime SLAs (Workato offers 99.99%), error handling capabilities (retry logic, dead letter queues), and monitoring/alerting features. G2 reviews are a good source for real-world reliability data. Also check: does the platform offer data processing logs and debugging tools? Can you set up automated alerts for failed integrations?

What is embedded iPaaS and should my SaaS product offer it?

Embedded iPaaS allows you to build integration capabilities directly into your SaaS product, letting customers connect your tool to their other applications. As the SaaS ecosystem grows, embedded integrations are becoming a competitive requirement. Tray.io is the strongest option for this use case among the platforms reviewed, offering white-label deployment options.

Can I use multiple iPaaS platforms together?

Yes, and many organizations do. A common pattern: Make for internal workflow automation + Workato for enterprise data sync + a custom or embedded solution for customer-facing integrations. Just be mindful of overlapping costs — maintaining multiple platforms can double your integration spending without clear benefit.

The Bottom Line

The iPaaS market has matured to the point where there is a clear platform for every use case. The biggest mistake B2B buyers make is choosing a platform designed for a different scale or use case than their own — using enterprise tools for simple workflows (overpaying) or consumer tools for enterprise needs (underpowered).

My recommendation: Start with Make for most B2B teams. It offers the best balance of power, flexibility, and cost. Upgrade to Workato when compliance requirements or enterprise system complexity demand it. Use Zapier only for the simplest, highest-volume self-serve needs where Make's learning curve is a barrier. Choose Celigo if your world revolves around NetSuite and EDI. And consider Tray.io exclusively for embedded integration or developer-heavy workflows where maximum flexibility is worth the complexity premium.

The integration platform you choose will shape how your entire SaaS stack operates for years to come. Choose carefully, but don't overthink it — the best platform is the one your team will actually use consistently.
