Comparing Census with Hevo and Weld
Carolina Russ6 min read
What is Census
Census is a leading Reverse ETL platform that syncs data from your data warehouse back into SaaS tools like Salesforce, HubSpot, and Marketo. It integrates deeply with dbt and modern warehouses, enabling no-code mapping, incremental upserts, and reliable syncs to operational systems in near real time.
Pros
- Warehouse-centric: works directly on tables or dbt models
- No-code field mapping with live previews
- Broad destination support: Salesforce, HubSpot, Slack, Google Sheets, etc.
- Incremental upserts ensure data consistency with no duplicates
- Deep dbt integration and “analytics-as-code” workflows (YAML config)
- Flexible scheduling and API triggers for near real-time use cases
Cons
- Focuses only on reverse ETL—requires a separate ELT tool for ingestion
- Pricing based on rows or syncs can be expensive at very large volumes
- Complex transformations must be done upstream in the warehouse/dbt
- Dependent on destination API rate limits, which can slow large syncs
- SaaS-only (no on-prem deployment)

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.
