Weld Pricing & Billing
Overview
Weld uses transparent, usage-based pricing model based on Monthly Active Rows (MAR), the number of data rows that change across your connected data sources in a given month. Unlike charging for API calls, sync frequency, or idle rows, Weld bills only for data that changes, so you only pay for what you actually move.
Note: Every plan includes a fixed amount of MAR. As long as you stay within that limit, your price stays the same. In case your data volume increases, you can simply add more MAR or move to a higher plan directly in the app.
You can add more MAR by either purchasing additional MAR add-ons or upgraiding to the next plan level. To purchase more MAR navigate to Account Settings and click on Plan Details & Billing.
- Under Plan you can see the details of your subscription. You can also adjust your subscription by clicking on Modify Plan.
- Under Billing you can see billing details, payment method, and billing history.
