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.”
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.
Improvado features a clean UI and guided setup, making it easy to extract, transform, and load data from various marketing platforms. Users can explore APIs via natural language using the AI Agent.
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 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.
Improvado’s pricing is custom and varies by data volume, sync frequency, and add-on features. While potentially costly, it's suited to enterprise use cases requiring robust data infrastructure.
Pricing is customized and generally pitched as more affordable than enterprise competitors, but small businesses may find entry costs high without a free tier.

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.”
