A reviewer on Capterra:
“Ease of use, various data connection points readily available for integration and extraction, ranging from Social platforms to various DSPs. Users can easily set up a frequent data update and even connect with other dashboards like Data Studio.”
Overview
Qlik Replicate (formerly Attunity) is a change data capture (CDC) and replication platform that moves data in real-time from databases, mainframes, and cloud sources into data warehouses, data lakes, and analytics platforms. It provides a graphical UI to configure replication tasks, automated schema change handling, and supports a wide range of sources (Oracle, SQL Server, DB2, MongoDB) and targets (Snowflake, Redshift, BigQuery, Kafka).
High-performance CDC with minimal source impact; supports heterogeneous sources and targets.
Automated schema change handling—table/column additions in source auto-reflected in target.
GUI-based configuration for tasks, monitoring dashboards, and robust error handling.
Cloud-native or on-prem installations; integrates with Qlik’s broader ecosystem (e.g., Qlik Sense).
No built-in ELT/transformations—only replication. Users need a separate tool for data transformations.
Enterprise pricing (per-core licensing) can be high, particularly for large-scale replication across many tables.
Learning curve for setting up advanced replication scenarios (e.g., multi-target replication, filters).
Gartner Peer Review:
“Meets data replication needs. Ability to 'read once write many' i.e. fork out data to multiple targets is a major plus.”
“Vendor need to work on enhancing capabilities e.g. Enabling additional ...”

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
Adverity offers a user-friendly interface but has a steeper learning curve due to its broad feature set, which might be overwhelming for beginners.
The Qlik Replicate UI provides wizards to create replication tasks quickly, monitors latency and throughput, and auto-detects schema changes. Setup for common CDC tasks is straightforward, but advanced filtering and tuning require expertise.
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.

Side-by-side
Adverity’s pricing is on the higher side, especially for small businesses, which may find the cost prohibitive. It is ideal for larger enterprises that need extensive data integration capabilities.
The licensing model is per-engine/core, often starting at $50k+/year for smaller environments. While expensive, the high reliability and low-latency replication justify cost for mission-critical use cases.
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.

Side-by-side
Adverity supports a wide range of connectors and provides robust data extraction, transformation, and loading capabilities. However, the platform's comprehensive feature set can be a double-edged sword, offering great functionality but also requiring significant effort to master.
Features: CDC-based replication, automated schema drift handling, support for 100+ sources/targets (databases, mainframes, cloud), multi-target replication, and basic transformations (e.g., data type conversions). No deep transformation engine.
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.

Adverity is highly customizable, offering flexibility to adapt to various data needs and integration scenarios, making it a strong choice for businesses that require tailored data solutions.
Users can configure advanced mapping rules, filters, and transformations (limited) via the UI or JSON configs. For deeper transforms, integrate with Qlik Compose or third-party ETL. Qlik Replicate can be automated via CLI and REST API.
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.
