Overview
Weld is a unified ELT and data activation platform that combines ingestion, modeling, transformations, orchestration, lineage, and reverse ETL in a single SaaS interface. With premium in-house–built connectors, an intuitive UI, and near real-time syncs, Weld enables both technical and non-technical users to create and manage data workflows efficiently. Weld also includes an AI assistant to support SQL modeling, generate transformations, and streamline repetitive tasks. Teams can ingest data from a wide range of sources—including marketing platforms, CRMs, databases, Google Sheets, Excel, and APIs—into their cloud data warehouse and activate it back into business tools.
Lineage, orchestration, and workflow features included by default
Handles large datasets and near real-time data sync
ELT and reverse ETL in one platform
User-friendly interface with minimal setup required
Flat, predictable monthly pricing model
200+ in-house–built, high-quality connectors
AI assistant for modeling and transformations
Some SQL knowledge is useful for advanced modeling
Optimized for cloud-warehouse workflows (Snowflake, BigQuery, Redshift, etc.)
Feature set is streamlined for modern ELT/activation use cases

Overview
AWS Glue is a fully managed, serverless ETL platform from AWS that automates data discovery, cataloging, and transformation using the Glue Data Catalog and Apache Spark (PySpark/Scala). It integrates tightly with AWS services such as S3, Redshift, RDS, and DynamoDB, and offers both batch and streaming ETL. Glue includes visual tools like Glue Studio and low-code data preparation via DataBrew, along with job scheduling, orchestration, and CloudWatch monitoring.
Serverless architecture—no infrastructure to manage; AWS automatically provisions compute (Spark-based).
Glue Data Catalog provides schema discovery, metadata storage, versioning, and integration with Athena and Redshift Spectrum.
Supports Python (PySpark) and Scala for complex ETL with transformation APIs.
Deep integration with AWS services including CloudWatch, IAM, S3 events, Step Functions, and Redshift.
Costs can be unpredictable for long-running or resource-intensive jobs due to DPU billing.
Debugging jobs can be challenging; logs spread across CloudWatch and Spark outputs.
Connecting on-prem or multi-cloud sources often requires additional networking configuration.
G2 Reviews:
“My team built a framework in AWS Glue to fetch data from multiple platforms and store it in S3 in the format we specified. It streamlined our integration and data collection.”
“It does not support XML file formats.”
Overview
Whatagraph is a cloud-based marketing reporting tool designed to help agencies and in-house teams create and automate visually polished reports. It connects to a range of marketing and advertising platforms and brings performance data together into a single reporting interface.
Easy to use for quick reporting
Visually appealing templates
Helpful for marketing agencies
Strong report automation features
Limited customization for advanced reporting needs
Higher pricing compared to similar tools
Narrower integration coverage than broader data platforms
Not suitable for complex data modeling or transformations
A reviewer on G2:
“Generating quality reports with ease is now possible thanks to this reporting tool. Our clients like the visuals, and the default templates help save time overall.”
“Customization options are limited and scaling reporting needs can get expensive.”
Side-by-side
Weld’s interface is built for clarity and speed, enabling users with varying levels of technical experience to manage data pipelines and models efficiently. Its built-in lineage and orchestration tools provide transparency across workflows.
Glue Studio offers a visual job builder, while more advanced workflows require writing PySpark or Scala code. The AWS console can feel complex for users unfamiliar with AWS services.
Whatagraph offers an intuitive interface and visually appealing templates, making it easy for marketing teams to generate reports without technical skills.

Weld offers a simple and predictable pricing model starting at $79 for 5 million active rows. This flat, usage-transparent structure makes budgeting straightforward for small and medium-sized teams.
Pricing is based on DPU-hours used by ETL jobs. Short jobs can be inexpensive, but longer Spark workloads or high-concurrency environments can increase costs without careful tuning.
Pricing is on the higher side compared to alternatives, which may be challenging for smaller teams, especially as reporting needs scale.

Weld provides ELT ingestion, SQL-based transformations, reverse ETL activation, data lineage, orchestration, and workflow management in a single platform. Its AI assistant accelerates modeling and transformation tasks.
AWS Glue includes the Glue Data Catalog, PySpark/Scala ETL jobs, Glue Studio for visual development, DataBrew for low-code data preparation, Glue Workflows for orchestration, and support for both batch and streaming ETL.
Whatagraph focuses primarily on marketing reporting and automation. While it supports many common marketing connectors, it lacks advanced features such as data modeling, transformations, and cross-system syncing.

Side-by-side
Users can model data using SQL enhanced by Weld’s AI assistant, automate workflows, and build custom connectors to any API. This provides strong flexibility for teams that want to tailor integrations and transformations within one platform.
Glue supports custom PySpark ETL scripts, additional Python libraries, event-based triggers, and integration with Lambda and Step Functions. Local development is possible but limited compared to full Spark environments.
The platform is straightforward for simple reporting but offers limited flexibility for deeper customization or complex data workflows, making it less suitable for technical or data-driven teams.

CUSTOMER STORIES
“One of the biggest impacts has been unlocking new ways to buy media. Before, we didn’t have the data to back up strategic decisions – now we do.”
“Before Weld, we had to rely on custom Python scripts and manual processes that were time-consuming and error-prone.”
“We’re still a team of three, but we’re often doing far more than the equivalent of three full-time employees. That’s down to how we're able to leverage systems, data, and processes.”
“We’ve always been a KPI-driven company. But we wanted to scale that mindset across every team member, every team, every decision.”
“Before Weld, our data infrastructure was limited and we relied heavily on Excel files and custom Python scripts.”
“Weld has saved us a ton of time, from not having data ready to having a fully functional data warehouse and connectors.”
“By integrating Weld, Amazon S3, and Databricks, Soundboks built a modern data pipeline that automates data ingestion, improves reporting, and provides up-to-date visibility into sales performance”
“We didn’t have a good data setup, so we lacked the business insights we needed. Weld has allowed us to set up a structured data infrastructure and access insights quickly.”
