What is Blendo
Blendo is a cloud-based ETL service that simplifies collecting data from popular SaaS tools (marketing, analytics, CRM) and loading it into a data warehouse or BI tool. It focuses on quick setup, automated schema updates, and easy data enrichment for marketers and analysts.
Pros
- Quick setup for popular marketing and product analytics sources with pre-built dashboards.
- Handles incremental syncs and auto-updates when source schemas change.
- Offers a unified metrics layer with common definitions (e.g., MRR, CAC) out-of-the-box.
Cons
- Niche focus on marketing/product analytics—fewer connectors for general-purpose ETL.
- Transformation capabilities are limited to simple mappings; complex needs require additional tools.
- Pricing scales quickly as more sources are connected or higher sync frequency is needed.

What I like about Blendo
Blendo’s turnkey dashboards and consolidated metrics saved us weeks of manual work—data from all our marketing tools was in BigQuery overnight.
What I dislike about Blendo
Limited customization: can’t define complex transformation logic beyond basic field mappings and date handling.
What is Dell Boomi
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.
Pros
- 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.
Cons
- 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:
What I like about Dell Boomi
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.
What I dislike about Dell Boomi
Licensing can be expensive, especially for high-volume data. Complex integrations can require coding despite the low-code promise.

A reviewer on G2 said:
What I like about Weld
First and foremost, Weld is incredibly user-friendly. The graphical interface is intuitive, which makes it easy to build data workflows quickly and efficiently. Even with little experience in SQL and pipeline management, we found that Weld was straightforward and easy to use. What really impressed me, however, was Weld's flexibility. It was able to handle data from a wide variety of sources, including SQL databases, Google Sheets, and even APIs. The solution also allowed us to customize my data transformations in a way that best suited my needs. Whether I needed to clean data, join tables, or aggregate data, Weld had the necessary tools to accomplish the task. Weld's performance was also exceptional. I was able to run large-scale ETL jobs quickly and efficiently, with minimal downtime via a Snowflake instance and visualization via own-hosted Metabase. The solution's scalability meant that I could process more data without any issues. Another standout feature of Weld was its support. I never felt lost or unsure about how to use a particular feature, as the support team was always quick to respond to any questions or concerns that I had. Overall, I highly recommend Weld as an ETL solution. Its user-friendliness, flexibility, performance, and support make it an excellent choice for anyone looking to streamline their data integration processes. I will definitely be using Weld for all my ETL needs going forward.
What I dislike about Weld
Weld is still limited to a certain number of integrations - although the team is super interested to hear if you need custom integrations.
Blendo vs Dell Boomi: Ease of Use and User Interface
Blendo
Blendo’s web UI focuses on connecting predefined sources (select connector, authenticate, choose tables). Once set, data flows automatically on a schedule. Very little configuration needed—ideal for marketers/analysts.
Dell Boomi
Boomi’s Integration Builder uses a web-based canvas to create process flows. Connectors and maps are configured via dialogs. Error-handling, version control, and deployment controls are integrated. Some users find building very complex workflows cumbersome despite the visual design.
Blendo vs Dell Boomi: Pricing Transparency and Affordability
Blendo
Plans start at $100/month for 1 source, 1 warehouse, and 1 dashboard sync. Higher tiers add connectors and more frequent syncs. Good value for small analytics use cases, but costs increase if you add many sources.
Dell Boomi
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.
Blendo vs Dell Boomi: Comprehensive Feature Set
Blendo
Features: SaaS connectors (marketing, CRM, product), incremental sync, metrics layer, pre-built BI dashboards (Data Studio, Looker), monitoring & alerts. Limited to analytics-focused data; no general-purpose ETL features.
Dell Boomi
Features: ETL/ELT processes, API management, EDI/B2B integration, workflow automation, data quality, and master data management. It also offers training, community forums, and professional services.
Blendo vs Dell Boomi: Flexibility and Customization
Blendo
Users can define custom SQL transformations on the loaded data via a “SQL runner” feature, but most heavy transformations are done post-load in the warehouse or BI tool. No built-in Python/JS transforms.
Dell Boomi
Custom scripting is supported via Groovy or JavaScript for complex transforms. Atoms can be deployed virtually anywhere for hybrid use cases. However, you rely on Boomi for core engine updates; it’s not open-source.
