Pricing that grows with your data

Yes. Every plan starts with a 14-day free trial with full access and no credit card, and usage during the trial isn't billed. There is no free plan after the trial. Sign up to start.

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 several Shopify stores, Postgres databases or Facebook Ad accounts and they count as one connector each.

A custom connector brings in a source that isn't on the standard Weld list, for example an internal API, a niche SaaS tool or a partner system. You define how to authenticate and which data to pull, and Weld treats it like any other connector.

It's typically written in Python with Weld's connector framework and runs on Google Cloud Functions, AWS Lambda, Azure Functions or any other environment that serves HTTP endpoints.

A custom connector counts as one connector type on your plan. Once it's built, you can reuse it for as many integrations as you need.

Yes, Weld prices by monthly active rows (MAR): the rows inserted or updated in your destination each month. Every plan includes a fixed number of them, and as long as you stay within it your price stays the same. If your volume grows, add rows or move to a higher plan directly in the app.

There are no extra costs for API calls, and a full sync counts each row once a month however often it runs. On incremental syncs, a row counts each time it changes and is synced, so syncing more often only adds usage for rows that change between syncs.

Active rows are the rows inserted or updated in your destination in a month, and they are what plans are measured in.

• On incremental syncs, each new or updated row counts. Rows that don't change don't count.
• On a full sync, each row in the table counts once a month, however often the table is resynced.
• Rows in subtables count like any other table. Rows in history tables count at 50%.
• Each extra ELT destination a sync loads into adds 50% of its active rows.

The first 14 days of a connector type you haven't used before (custom connectors get 14 days per connection), the first sync of a new table, resyncs Weld runs itself and backfills you ask support for are free. See a worked example.

Accounts created before October 19, 2026 move to these rules on January 1, 2027. What's changing.

You don't have to guess. Start a free trial or connect a type of source you haven't used before, or a new custom connector, and let it run for its first 14 days: Weld counts your monthly active rows without charging for them.

In the app you can follow your usage and growth, and Projected Usage on Plan Details & Billing estimates where the current billing cycle will end, so you can see what you need before you commit to a plan. How the forecast works.

No. Everything a connector type you haven't used before syncs in its first 14 days is free, and so is the first sync of each table you add later.

The 14 days start the first time you connect that type of connector. A second connection of the same type, for example a second Shopify store, doesn't start a new 14 days, but the first sync of each of its tables is still free. Custom connectors get 14 days per connection.

To reload history for a table you already sync, ask us in the support chat and we'll run the backfill free of charge. Full syncs you start yourself count once a month, like any full sync.

Yes. Connect dbt Cloud under Settings → Transform and Weld can trigger your dbt jobs as part of an orchestration, right after the syncs they depend on. With dbt Core, trigger a Weld orchestration from your dbt workflow through the Weld API. Cube and SQLMesh jobs run as orchestrated steps too, triggered by webhook, with a direct webhook for Cube. You can also keep Weld's own SQL models in GitHub with GitHub Sync. The dbt integration is on Premium and up. dbt Cloud · dbt Core.

Tell us in the chat in your workspace or on the support page. We build new connectors based on what customers ask for.

If you need the data now, you can build a custom connector for any API. It counts as one connector type on your plan however many times you use it.

Monthly or annual subscriptions, paid by credit card or invoice depending on the plan. Paying annually saves 20%. Basic and Premium can be paid monthly or annually; Business and Enterprise are billed annually. Subscription docs.
