Overview
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.

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.
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):
“Alooma’s ease of connecting live streaming data sources directly into BigQuery with automated schema management was revolutionary for our real-time analytics.”
“Since Google integrated Alooma into its native services, the standalone product no longer exists, so new users must migrate to Dataflow or Data Fusion.”
Overview
Integrate.io (formerly Xplenty) is a low-code/no-code data integration platform that unifies ETL, ELT, and reverse ETL in a single solution. It features a drag-and-drop interface for building pipelines and supports over 150 pre-built connectors for databases, SaaS apps, and REST APIs. Designed for both cloud and hybrid environments, it offers on-premise agents for secure local data access. Integrate.io supports complex workflows with scheduling, transformation logic, and change data capture (CDC), while also enabling reverse ETL to push data back into operational systems like CRMs. With built-in monitoring, alerts, and customer support, it’s a strong option for teams seeking a user-friendly yet powerful integration platform.
100+ pre-built connectors covering both operational (reverse ETL) and analytical use cases
Low-code visual pipeline builder with rich transformation expressions
Supports hybrid deployments via secure agent for on-prem sources
Unified platform for ETL, ELT, and reverse ETL
Robust workflow orchestration and scheduling features
Cloud-only SaaS (no fully on-prem option)
UI can feel complex initially due to breadth of features
Less polished transformation debugging compared to dedicated tools like Matillion
Pricing can be high for small teams; custom quotes required
Documentation sometimes lagging on newer features
G2 Review:
“The system was easy to integrate and flexible for all of our systems. The system is reliable with little or no maintenance or intervention needed to maintain consistent data flows. They have excellent support and communication in both timelines and quality of response.”
“There is a learning curve that can take some time to leverage more complex transformations and the support is limited with highly complex setups leaving some aspects of development more difficult.”

A reviewer on G2 said:
“Weld is still limited to a certain number of integrations - although the team is super interested to hear if you need custom integrations.”


Side-by-side

Alooma’s web-based pipeline builder allowed users to drag-and-drop connectors for streaming or batch data, apply transformations, and route data to BigQuery with just a few clicks. The interface auto-generated SQL when possible.
Integrate.io offers a drag-and-drop canvas for building pipelines, which is intuitive for new users but requires some ramp-up to master its full capabilities.
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.

No longer available as a separate product. Users adopt equivalent GCP services (Dataflow, Data Fusion) which have pay-as-you-go pricing under the GCP pricing model.
Pricing is customized and generally pitched as more affordable than enterprise competitors, but small businesses may find entry costs high without a free tier.
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.

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.
A breadth of features: ETL/ELT connectors, reverse ETL for operational syncs, built-in transformation expressions, API generation, and workflow automation. It also provides data governance tools like environment promotion.
Weld integrates ELT, data transformations, and reverse ETL all within one platform. It also provides advanced features such as data lineage, orchestration, workflow management, and an AI assistant, which helps in automating repetitive tasks and optimizing workflows.

Users could write custom JavaScript transforms or Python UDFs for complex logic. The platform managed infrastructure, but custom connectors required Eloqua code or support.
Integrate.io allows custom scripting (JavaScript or SQL) within pipelines and secure agent deployment for on-prem sources. Its API and SDK enable integration into CI/CD, but ultimate customization is bounded by the platform’s framework.
Weld offers advanced SQL modeling and transformations directly within its platform with the help of AI, providing users with unparalleled control and flexibility over their data. Leveraging its powerful AI capabilities, Weld automates repetitive tasks and optimizes data workflows, allowing teams to focus on getting value and insights. Additionally, Weld's custom connector framework enables users to build connectors to any API, making it easy to integrate new data sources and tailor data pipelines to meet specific business needs. This flexibility is particularly beneficial for teams looking to customize their data integration processes extensively and maximize the utility of their data without needing external tools.
