Integration platforms split by who is expected to operate them. No-code iPaaS — Zapier, Make, Activepieces — puts connections in the hands of whoever needs them. Developer-first platforms — Pipedream, n8n, Windmill — assume a code step is faster than a config screen. Enterprise iPaaS — Workato, Tray.ai, MuleSoft, Boomi — sells governance, environments and a support contract alongside the connectors. And a fourth option that rarely appears on these lists: when the integration is the product rather than plumbing between other people's products, Greta builds the application that owns the data and calls the APIs directly. Pick the tier by who maintains it in month six, not by connector count.
Every iPaaS vendor advertises the same two numbers: how many connectors they have, and how fast you can build your first automation. Neither predicts what the thing costs to own. What predicts that is who is expected to fix it at 9am when a vendor changes an API response.

The tiers, honestly
No-code iPaaS earns its place on breadth and accessibility. Zapier's catalog is the category's widest, and that genuinely matters when the long tail of SaaS is your integration surface. Make trades some approachability for real branching and iteration; Activepieces gives the same shape as open source. The shared limit is debuggability rather than version control: both Zapier and Make do offer version restore, so "no rollback" would be wrong — check your plan, because availability is tiered. What is genuinely missing is a reviewable diff between versions and automated test coverage, so past about ten steps the canvas stops explaining itself and restoring an older version is the only way back.
Developer-first platforms fix exactly that. Pipedream and n8n let a step be code, which means a hard problem gets solved in five lines rather than four modules and a formatter. n8n self-hosted also removes usage pricing, at the cost of running a service. The trade is who can maintain it — these are developer tools with a friendly surface, not no-code tools with an escape hatch.
Enterprise iPaaS is a different purchase entirely. Workato, Tray, MuleSoft and Boomi sell environments, approvals, audit trails, role separation and someone to call. That is worth real money when integrations carry regulated data or cross departments; it is a procurement exercise when you have six workflows.

The question that sorts the tiers
Ask: when this breaks at 9am on a Tuesday, who fixes it, and what do they look at? No-code answers "whoever built it, in the canvas." Developer-first answers "an engineer, in the code." Enterprise answers "the integration team, in the run log." If your honest answer is "nobody knows, we'd rebuild it" — the workflow is load-bearing and undocumented, and no tier on this list fixes that by itself.
When the integration is the product
The fourth option applies when the data belongs to you. If the "integration" is really an ordering system that talks to a payment provider and a shipping API, iPaaS is the wrong shape: you are keeping the business's real state in a spreadsheet so that workflows can read it. Describing the system to Greta builds the app that owns that state and calls the APIs itself — real tables, real logic, deployed, with the free tier (30 credits a month, 5 a day) covering the first version and $20/month flat after ($5 with the current welcome offer).
Where this is the wrong answer, plainly: connecting SaaS products you don't own — Slack to Notion, Typeform to Airtable — is exactly what iPaaS is for, and building an app to do it would be absurd. Our Zapier alternatives guide covers that side by exit reason.
FAQ
What is an API integration platform? Software that connects applications without you writing and hosting the connection yourself — triggers, actions, data mapping, retries and monitoring, delivered as a managed service.
What is the best iPaaS for a small team? Zapier if breadth and accessibility matter most, Make if cost per operation matters more, n8n or Activepieces self-hosted if you would rather pay in infrastructure than subscription. Enterprise iPaaS is rarely the right first purchase.
How much do integration platforms cost? No-code tiers commonly run tens to low hundreds per month and scale with task or operation volume; enterprise platforms are quoted and annual (September 2026 shapes — verify live). The cost people forget is maintenance time when a vendor changes an API.
Can I replace an integration platform with custom code? For integrations central to your own product, often yes, and an AI app builder makes that practical without a development team. For the long tail of third-party SaaS connections, no — that is what the connector catalogs are for.
