Overview

Estuary in Short

Estuary Flow is a real-time ETL/ELT and data integration platform for both batch and streaming pipelines. It provides sub-100ms latency using Change Data Capture (CDC), supports automated schema evolution, and allows users to build entire pipelines with low- or no-code connectors in minutes. It can target data warehouses (e.g., Snowflake, BigQuery), BI tools, and operational systems for analytics, operations, and AI use cases.

Pros

Purpose-built for real-time CDC and streaming ETL with sub-100ms latency.
Automatic schema evolution with exactly-once delivery guarantees.
200+ no-code connectors for databases, SaaS apps, and message queues.
Flexible deployment: public cloud, private cloud, or self-hosted (BYOC).

Cons

Premium pricing model ($0.50/GB consumed + connector fees) can be expensive for small teams.
Still growing connector catalog; niche or very new APIs may require custom work.
Smaller community compared to older open-source tools, meaning fewer community-built resources.

What I like about Estuary

“Estuary’s real-time, no-code model is magical—getting data instantly with minimal effort and near-zero pipeline maintenance. Plus, their support is fantastic.”

What I dislike about Estuary

“Pricing can be high for lower-volume teams, and some less-common connectors are still in development, which limits immediate use cases for niche sources.”

Overview

Hightouch in Short

Hightouch is a Reverse ETL platform and “Composable CDP” that syncs data from warehouses (Snowflake, Redshift, BigQuery) to 70+ SaaS destinations (CRMs, ad networks, email platforms). It empowers marketing and operations teams with a visual audience builder, no-code syncs, and SQL customization for precise data activation.

Pros

No persistent data storage—fetches on-the-fly from your warehouse for security
Support for real-time streaming and sub-minute latency syncs
Granular field mapping and transformation via SQL or simple expressions
Strong community, educational content, and responsive support

Cons

Reverse ETL only—needs a separate ingestion tool
Pricing based on rows/fields can become expensive at scale
Destination API limits (e.g., Salesforce) can slow large syncs
Custom connectors for very niche tools require waiting for team prioritization
Non-engineers may still need data team to model data for complex use cases

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.”

Ease of Use & Interface

Side-by-side

Estuary

Estuary’s UI is intuitive: users can add connectors, configure CDC streams, and specify destinations in a few clicks. Complex transformations can be written in SQL or TypeScript directly in the Flow editor, but most tasks are handled via no-code connectors.

Hightouch

Hightouch’s interface is modern and intuitive, with an audience builder that lets marketers define segments visually. Technical users can drop into SQL for precise control.

Weld

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.

Pricing & Affordability

Side-by-side

Estuary

While Estuary provides a 10 GB/month free tier and a 30-day trial, its consumption-based pricing ($0.50/GB + connector fees) can become costly at scale. Teams processing hundreds of GBs per month should budget accordingly.

Hightouch

Starts free for light use, but professional tiers scale with usage. For mid-market teams, the cost is justified by reduced engineering overhead, though very large sync volumes can be pricey.

Weld

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.
