Frends vs Boomi 2026: the #1 Boomi alternative for European enterprises

Why enterprise teams move from Boomi to Frends

The cost of growing your integration landscape keeps climbing

Boomi's pricing scales with the number of applications, connectors and environments you integrate. It can feel manageable early in an integration program, but as new systems, partners and APIs are added, each expansion triggers a licensing conversation. Some integrations never get built because the connector cost makes the business case too thin, and those become the manual workarounds, data gaps and delayed digital initiatives that accumulate across the organization. Frends pricing is structured around processes rather than the number of systems connected, so adding a connector or application does not automatically increase the platform cost.

Boomi's model creates duplicated logic that is hard to maintain

In Boomi environments, similar integrations are frequently built as separate flows rather than variations of a shared pattern. Over time that becomes a landscape of duplicated logic that is expensive to update, difficult to govern and time-consuming to troubleshoot. Frends addresses this through reusable subprocesses: common logic is built once and called from multiple parent processes. In one Boomi-to-Frends migration, 26 near-identical Boomi processes were consolidated into a single shared Frends subprocess.

Boomi's architecture gives regulated sectors less control

Boomi supports hybrid deployment and flexible runtimes, but the control plane remains cloud-managed by default. For enterprises with strict data residency requirements, air-gapped networks or a mandate to keep sensitive processing inside their own infrastructure, that default creates constraints. Frends Agents run in public cloud, private cloud, on-premises servers or hybrid combinations, and organizations that require the management plane itself to be self-hosted can have it without architectural compromise.

What building on Boomi feels like day to day

Feedback from the people who build and run integrations on Boomi, and how Frends answers each point.

No real development environment

Boomi's test mode runs in the browser, caps the number of documents and does not reflect production. There is no local runtime, debugger or unit testing, so test-driven development is practically impossible. Frends gives builders local development, step-by-step process debugging and real execution history.

Versioning without branches, diffs or merges

Boomi versioning is per component, with no branches, diffs or merges. Git export is possible, but components are XML blobs full of GUIDs, so diffs are useless for code review. Frends processes are BPMN 2.0 definitions that can be reviewed, versioned and promoted through normal deployment practice.

Error handling has to be hand-built

In Boomi, Try/Catch works only within a single branch and loses document context with some connectors. Retry is limited to a number of attempts, with no backoff or conditions, and dead-letter handling and compensation must be built by hand. In Frends, retries, conditions, error paths and compensation are first-class parts of the process model.

Observability disappears when you need it most

Boomi's Low Latency mode, required for synchronous APIs, disables execution history and document storage in Process Reporting, so production errors must be reproduced blind or covered by custom logging. Frends keeps full execution visibility on synchronous APIs too.

Promotion between environments is error-prone

Per-environment configuration in Boomi goes through Extensions, which are easy to skip or misconfigure, and the lack of native CI/CD forces workarounds through the platform API. Frends uses environment-aware configuration and API-driven deployment.

A closed process format is a lock-in cost

Boomi's process notation is proprietary and has no equivalent in any standard, so moving to another platform means rewriting integrations from scratch. This is a portability concern rather than a feature gap: iPaaS platforms generally do not use BPMN. Frends builds on BPMN 2.0, a documented standard that keeps process logic readable and portable.

Frends vs Boomi: key differences

Total cost of ownership

The clearest way to understand the TCO difference between Frends and Boomi is to look at what happens when an integration program grows. In Boomi's model, adding connectors, applications, API capacity or environments adds cost. In Frends' model, growing the integration footprint does not automatically trigger a pricing increase, because the platform charges by process rather than by the number of systems connected.

Internal competitive analysis positions Frends as up to 50% lower TCO than Boomi in enterprise integration scenarios, with savings driven by three factors: pricing model predictability, reduced maintenance overhead through reusable subprocesses, and the elimination of module sprawl by combining integration, API management and orchestration in a single commercial package.

Customers who chose Frends over Boomi

• Ammattiopisto Spesia Oy — Finland's second-largest special vocational institution migrated from Boomi to Frends in early 2026. Each new Boomi connector carried an annual cost increase in the thousands of euros, so some integrations were left unbuilt. After migrating, Spesia's annual platform cost dropped 40% and maintaining consistent integration logic became significantly easier. Mikko Lackman, Spesia's integration builder: "Pricing flexibility is probably one of the most important features for an organization like ours. The biggest advantage with Frends: a change made in one place is reflected everywhere."
• Marioff (January 2025) — Selected Frends after a hands-on proof of concept that demonstrated faster delivery and lower complexity than Boomi.
• Arvos Ljungström (November 2024) — Chose Frends for lower Total Cost of Ownership, ease of use, and better fit for specific business integration use cases.
• Voglio (April 2025) — Frends won the deal in a competitive evaluation involving previous Boomi use cases.
• Pirkanmaan Jätehuolto Oy (February 2025) — Selected Frends over Boomi in a competitive process.
• Spectrum Safety Solutions — Migrated 14 integrations from a mix of platforms including Boomi to Frends.

EU data sovereignty

For European enterprises, vendor jurisdiction is increasingly a formal procurement consideration alongside data residency and GDPR compliance. Frends is headquartered in Europe, runs on European infrastructure and is designed to support the data sovereignty requirements of regulated industries from the ground up. For organizations that need the management plane to operate inside their own infrastructure, Frends supports fully self-hosted deployment, and air-gapped and private cloud architectures are supported without architectural workarounds. Boomi is a US-headquartered platform: multi-region deployment is available and compliance options exist, but the platform's ownership and default cloud architecture are American.

Frequently asked questions

Why are enterprises moving from Boomi to Frends?

The most common trigger is cost expansion. Boomi's pricing scales with the number of applications, connectors and environments, which means integration programs become more expensive to grow over time. Some integrations go unbuilt because the connector cost makes the business case too thin. Frends uses a process-based pricing model that does not automatically increase as the integration footprint expands, making it easier to plan and prioritize at scale.

How much can switching from Boomi to Frends save?

Internal competitive analysis positions Frends as up to 50% lower TCO than Boomi over three or more years, driven by pricing model predictability, reusable subprocess architecture and unified platform packaging.

Does Frends support the same hybrid deployment capabilities as Boomi?

Frends supports cloud, on-premises, private cloud and hybrid deployment through the Frends Agent model. For organizations that require the management plane itself to be self-hosted, that option is available. Frends also supports air-gapped and network-isolated environments. The key difference is that data residency and network boundary requirements can be met without architectural compromise rather than through additional configuration.

How does Frends handle integration reuse compared to Boomi?

Frends uses a shared subprocess model where common logic is built once and called from multiple parent processes. A change to the shared subprocess propagates across every integration that uses it, significantly reducing ongoing maintenance effort. Boomi supports reuse, but environments with many similar integrations often accumulate duplicated logic that is expensive to keep consistent.

Is Frends suitable for enterprises already invested in Boomi?

Yes. Many organizations run Frends alongside Boomi, using Frends for new integration projects while existing Boomi integrations remain in place. A phased migration approach allows teams to move integrations to Frends at a pace that suits the organization, starting with new builds or high-maintenance existing integrations, without requiring a full cutover.

What do Boomi developers most often complain about?

The recurring themes are tooling rather than connectors: no local runtime, debugger or unit testing, so test-driven development is impractical; per-component versioning that produces GUID-heavy XML and makes code review useless; error handling that has to be hand-built because Try/Catch is branch-scoped and retry has no backoff or conditions; and Low Latency mode disabling execution history exactly where synchronous APIs need it. Promotion between environments through Extensions is easy to misconfigure, and the proprietary process format means leaving the platform involves a rewrite.

Does Frends support proper version control, testing and CI/CD?

Yes. Frends processes are BPMN 2.0 definitions that can be reviewed and versioned like other deliverables, builders get local development and step-by-step debugging with real execution history, and deployment is API-driven with environment-aware configuration, so promoting from development to test to production is a repeatable step rather than a manual checklist.
