Overview
Blendo in Short
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.

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.

Ease of Use & Interface
Side-by-side
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.
Etlworks Integrator
Etlworks Integrator’s Flow Designer uses a canvas with source, transformation, and destination steps. While powerful and flexible, the interface has a steep learning curve; nested steps and branching can become difficult to visualize.
Weld
Weld is highly praised for its user-friendly interface and intuitive design, which allows even users with minimal SQL experience to manage data workflows efficiently. This makes it an excellent choice for smaller data teams or businesses without extensive technical resources.

Pricing & Affordability
Side-by-side
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.
Etlworks Integrator
Charges are based on credits consumed by data volume and transformations. Free trial provides limited credits. For predictable workloads, budget forecasting requires careful usage analysis.
Weld
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.
