A connector links Weld to your apps, databases, or ad platforms so you can move data to and from them. Each connector supports as many syncs and accounts as you need.
We only count unique connector types — for example, you can connect multiple Shopify stores, Postgres databases, or Facebook Ad accounts using just one connector for each type.

A custom connector lets you bring a source that isn’t on the standard Weld list — for example, an internal API, niche SaaS tool, or partner system. You define how to authenticate and which data to pull, and Weld treats that connector like any other.
It’s typically written in Python using Weld’s connector framework and can run on Google Cloud Functions, AWS Lambda, or Azure Functions — or any other environment that supports HTTP endpoints.
Important: a custom connector counts as one connector type in your plan. Once it’s created, you can reuse it and deploy multiple integrations without paying for extra connectors.

Yes, Weld uses a usage-based pricing model, but it’s designed to be predictable and transparent. You’re billed based on Monthly Active Rows (MAR), which represent the number of rows that change or update across your data sources each month.
Every plan includes a fixed amount of MAR. As long as you stay within that limit, your price stays the same. If your data volume increases, you can simply add more MAR or move to a higher plan directly in the app.
There are no extra costs for sync frequency, API calls, or how often your connectors run — you only pay for the data that actually moves.

There are no extra costs for sync frequency, API calls, or how often your connectors run — you only pay for the data that actually moves.
An Active Row is any row of data that is either inserted or updated during a given month. Weld measures your usage based on the total number of rows that change across all your connected sources within that period.
Rows that don’t change are not counted again in the following months, so you only pay for the data that’s actually new or updated.
Rows that don’t change are not counted again in the following months, so you only pay for the data that’s actually new or updated.
You don’t have to guess — you can set up a free trial or connect a new source and let it run for the first 14 days. During this period, Weld tracks your Monthly Active Rows (MAR) automatically without charging for usage.
Inside the app, you can monitor your exact usage and growth trends, and use the Usage Forecast Estimator in the billing section to predict future MAR needs as your data grows.
This makes it easy to understand your expected volume before committing to a paid plan.

No — Weld doesn’t charge for initial or historical data loads. When you connect a new data source, you automatically get 14 days of free usage to complete your first full syncs without it counting toward your Monthly Active Rows (MAR).
This means you can onboard new connectors, test pipelines, and backfill historical data safely before your billing starts.
