The Fivetran alternative
with a bill you can predict

Fivetran's Standard plan works out to $500 per million monthly active rows, and every worked example on its pricing page divides out to that rate. Each connection is metered on its own curve, and connections producing between 1 and 1 million rows carry a $5 minimum charge. So 8 sources totalling 10 million rows a month comes to roughly $4,700, before reverse ETL, which is billed separately at around $200 per destination. The calculator on this page estimates your own figure.

It depends on volume, but the saving comes from the pricing model rather than a discount. A team running 8 sources and 10 million monthly active rows would pay around $4,700 on Fivetran Standard and $719 on Weld, roughly 85% less, with reverse ETL, orchestration and lineage included rather than billed on top. From 15M monthly active rows the saving is 50% or more on every setup in our calculator. Savings shrink at very low volumes, where Fivetran's free plan or metered pricing can be cheaper than a flat tier.

Weld, if what pushed you off Fivetran is the bill or the number of tools around it. Weld replaces per-row, per-connection metering with a flat monthly tier, and puts reverse ETL, lineage, orchestration for dbt, an AI agent and an MCP server in the same product, from $99 a month. Fivetran's schemas carry over, so dbt models and dashboards keep running, and Weld's engineers do the migration at no cost. Airbyte suits teams that want to self-host open source and operate it themselves. Stitch and Hevo are cheaper on simple ingestion but thinner on transformations and activation.

Yes. Weld sells tiers instead of metering rows. Each plan includes a monthly row allowance and a set number of connectors, and the price is fixed within them. Going past them changes the bill in known steps: more rows move you to the next row tier, each extra connector is a flat monthly fee, and larger plans include more of both. Fivetran's bill moves with every row on every connection. Plans start at $99 a month, billed annually, for 5 million rows and 2 connectors, and the calculator on this page shows which tier fits your volume.

Weld is SOC 2 Type II audited and penetration tested. It runs in AWS and Google Cloud data centres certified to SOC 2 and ISO 27001, is hosted in the EU, and publishes its DPA and subprocessor list. The SOC 2 Type II report is available under NDA through the security page.

Yes. Ed, Weld's own agent, works inside the product: it finds the tables, writes the SQL and checks it against your warehouse before showing it to you. Your own agents and tools can run Weld through the MCP server and the API, for example to create a sync or trigger a model.

Yes, and our team does the work at no cost. Weld is reverse compatible with existing Fivetran destination schemas, so the dbt models, dashboards and reports built on top of them keep working. We recreate your connectors and transformations, run both stacks in parallel, and you cut over once the row counts and metrics reconcile. During the parallel run you pay for both until Fivetran is cancelled, so plan the cutover before your renewal. How a Fivetran migration works.

On G2, reviewers rate Weld's quality of support 9.6 out of 10 and Fivetran's 8.5, and support is the thing Weld's reviewers mention most. Support is personal: you talk to people who know your setup, and a shared Slack channel with our team is an option. Weld's support hours are Monday to Friday, 9:00 to 17:00 Copenhagen time, and response times are written into the SLA: with Priority support, a critical issue gets a first response within 15 minutes. Service Level Agreement.

Fivetran lists 700+ connectors, including Lite connectors built for narrow use cases that cover fewer endpoints. Weld has 300+, built and maintained by Weld's own engineers, apart from a handful of community connectors that are labelled as such. What matters is whether the sources you replicate today are covered: the quiz on this page checks your list against Weld's catalogue. If one is missing, you can build it against any API with Weld's custom connector support.

Yes. Our team maps every connector you run on Fivetran, rebuilds it in Weld with the same schemas and table names, runs both side by side and helps you cut over once the numbers match. The migration work is included at no cost; while both run, the Weld plan and Fivetran are each billed as usual. After the move, Weld's forward deployed engineers can also work on the rest of your stack, such as your dbt project or your Snowflake, BigQuery or Databricks setup.
