What is Alooma

Alooma (acquired by Google Cloud in 2019) was a streaming ETL platform that enabled real-time ingestion of data from various sources into BigQuery. It provided a visual pipeline editor to map, transform, and route data with minimal code, automatically handling schema changes and ensuring exactly-once delivery. While Alooma as a standalone product is retired, many of its features have been integrated into Google Cloud’s Dataflow and Pub/Sub pipelines.

Pros

  • Real-time streaming ETL with automatic schema drift handling.
  • Minimal coding: visual pipeline UI with built-in connectors to databases, Kafka, APIs, and SaaS apps.
  • Exactly-once delivery guarantees to BigQuery, eliminating duplicate data.

Cons

  • Standalone Alooma product is discontinued—functionality now lives in GCP services (e.g., Dataflow, Data Fusion).
  • Migrating legacy Alooma pipelines to GCP-native services requires rework, as UI and features differ from original Alooma.

Google Cloud’s Dataflow (Alooma integration):

What I like about Alooma

Alooma’s ease of connecting live streaming data sources directly into BigQuery with automated schema management was revolutionary for our real-time analytics.

What I dislike about Alooma

Since Google integrated Alooma into its native services, the standalone product no longer exists, so new users must migrate to Dataflow or Data Fusion.

What is Supermetrics

Supermetrics is a powerful data integration tool that's particularly popular among marketers. It allows you to fetch data from various marketing platforms, such as Google Ads, Facebook Ads, and Google Analytics, and then transfer it into a data warehouse, spreadsheet, or BI tools like Looker, Google Data Studio, or PowerBI. The automation it provides saves time and reduces the chance of errors that come with manual data transfers.

Pros

  • Easy to use
  • Pre-built reports
  • Google Sheets destination
  • Flexibility in data storage and visualization options

Cons

  • Complex pricing model
  • Expensive
  • Limited data transformation capabilities
  • Slow data refresh rates
  • Can be glitchy
  • Not suitable for very large datasets

A reviewer on G2:

What I like about Supermetrics

Supermetrics is so easy to use, and the user interface for Google Sheets is intuitive and fast. There is a huge number of connectors available. I liked the scheduling options in my legacy plan, with hourly refreshes available. The customer support is premium and fast.

What I dislike about Supermetrics

There is a limited set of connectors available in the less expensive pricing plans, and the pricing has increased significantly over the years.

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.

Supermetrics

The pricing model for Supermetrics can be complex and expensive, which might be a concern for small businesses or those with limited budgets.

Alooma vs Supermetrics: Comprehensive Feature Set

Alooma

Alooma supported real-time ingestion from Kafka, databases (MySQL, PostgreSQL), logs, REST APIs, and SaaS apps, with built-in transformations (masking, enrichment). It automatically handled schema changes, and could write to BigQuery partitions.

Supermetrics

Supermetrics offers pre-built reports and flexibility in data storage and visualization, but has limited data transformation capabilities and may have slow data refresh rates.

Alooma vs Supermetrics: Flexibility and Customization

Alooma

Users could write custom JavaScript transforms or Python UDFs for complex logic. The platform managed infrastructure, but custom connectors required Eloqua code or support.

Supermetrics

Supermetrics provides flexibility in where data can be stored and visualized, but may lack advanced customization options for more technical users.
