Overview
Dell Boomi AtomSphere is a cloud-native iPaaS that provides ETL, API management, B2B/EDI integration, and workflow automation via a visual “Atom” runtime architecture. It supports 200+ connectors (SaaS, on-prem, databases) and allows users to build, deploy, and manage integration processes (called Atoms) in a drag-and-drop interface. Boomi’s AtomSphere runs on a lightweight runtime engine that can be deployed in the cloud or on-premise for hybrid scenarios.

200+ connectors for SaaS, on-prem, and big data sources.
Cloud-native or on-prem Atom runtime allows hybrid deployments.
Visual process designer with drag-and-drop mapping, enriched by shape-specific logic (e.g., function, decision, loop).
Built-in error handling, version control, and CI/CD integration.
Costly licensing structure (per-connection, per-Atom), which can escalate for high throughput or many connectors.
Complex transformations sometimes still require scripting (JavaScript/Groovy), reducing low-code benefits for advanced scenarios.
Learning curve: mastering Atoms, Molecules, and hybrid architecture requires time, particularly for non-technical users.
Dell Boomi Documentation:
“Boomi’s AtomSphere makes deploying integration processes easy—Atommachines can run anywhere (cloud or on-prem), and the visual interface is intuitive for building mappings.”
“Licensing can be expensive, especially for high-volume data. Complex integrations can require coding despite the low-code promise.”
Overview
Funnel.io is a cloud-based marketing data hub that helps marketers collect, organize, and analyze data from all of their marketing channels in one place. It also provides users with tools to visualize and share their data, and to create custom reports. Funnel.io is designed to be easy to use, even for marketers without a technical background.
Great interface
Requires little technical expertise
Straightforward dashboard
More than 500 data connectors
Great onboarding and training
Expensive and complex, especially for smaller businesses
Limited advanced analytics
Reporting features could be more robust
Limited to marketing use cases
Steep and long learning curve
A reviewer on G2:
“We use Funnel mostly for ingesting data into BigQuery. Using the native connectors is significantly more efficient than building a direct connection to the relevant APIs, particularly for Facebook / Meta data.”
“Recently the price of the platform has gone up. Although it is still priced competitively vs its alternatives.”

Boomi’s pricing is multi-faceted—permanent Atom licenses, per-connection pricing, and usage-based charges for transactions. SMBs may need to request custom quotes to stay within budget.
Funnel.io's pricing can be complex and expensive, especially for smaller businesses, which might find it challenging to justify the cost for their needs. The platform operates on a flexpoints system, a type of consumption-based pricing, which can make it difficult for users to predict their monthly costs accurately.
Weld offers a straightforward and competitive pricing model, starting at $79 for 5 million active rows, making it more affordable and predictable, especially for small to medium-sized enterprises.
