faucet-stream vs. Fivetran
Fivetran is a fully-managed SaaS; faucet-stream is a binary you own. Here’s the honest trade-off.

The short version
Fivetran is a fully-managed, closed-source ELT SaaS: you configure connectors in its UI, and Fivetran hosts and operates everything — scheduling, retries, schema handling, and connector maintenance. It has a large catalog (500+), strong log-based CDC, and usage-based pricing (monthly active rows).
faucet-stream is the opposite model: a self-hosted, open-source binary (and library) you run on your own infrastructure, with pipelines defined as version-controlled YAML and governance built into the movement path — no per-row bill, no vendor lock-in, data and credentials never leaving your systems.
Reach for faucet-stream when you want to own the pipeline — self-hosted, config-as-code, and free of usage-based cost.
Where faucet-stream is different
- Self-hosted and open source. Data and credentials stay on your infrastructure; there’s no third party in the path and no lock-in. You run one binary on compute you already have.
- Config-as-code. Pipelines are version-controlled YAML you diff, review, and run in CI — not UI state in someone else’s account.
- Predictable cost. No monthly-active-rows pricing that scales with data volume; you pay only for the compute you’d run anyway.
- Governance in the movement path. Data-quality checks, versioned data contracts, PII masking (before any sink sees a row), schema-drift policy, column-level lineage (OpenLineage) + a catalog, and freshness/volume SLAs — native, not paywalled add-ons.
- Embeddable. Compile the same engine into your own Rust service via the typed
Source/Sinktraits.
Where Fivetran is the better choice
Straight with you — a managed service earns its keep in real ways:
- Zero maintenance. Fivetran operates the connectors, absorbs upstream API changes and schema drift, and provides enterprise support and compliance. You don’t run or babysit anything.
- Catalog breadth. 500+ professionally-maintained connectors across a long tail of SaaS sources.
- You want a product, not a tool. Where the operational burden of self-hosting outweighs the cost and control trade-offs, a managed SaaS is the right call.
Side-by-side
| faucet-stream | Fivetran | |
|---|---|---|
| Model | self-hosted open-source binary + library | fully-managed proprietary SaaS |
| Pipeline definition | version-controlled YAML/JSON | UI (also API / Terraform) |
| Connectors | 58 built-in | 500+ managed |
| Change data capture | ✓ Postgres / MySQL / Mongo | ✓ log-based |
| Where data / credentials live | your infrastructure | Fivetran’s infrastructure |
| Cost model | free (compute you already run) | usage-based (monthly active rows) |
| Governance in-path (quality / contracts / masking / lineage / SLA) | ✓ native | partial / paywalled |
| Embeddable as a library | ✓ (Rust) | ✗ |
| License | MIT / Apache-2.0 | Proprietary |
Migrating from Fivetran
The mental model maps cleanly onto config-as-code:
| Fivetran | faucet-stream |
|---|---|
| a source connector (UI) | a source block |
| a destination | a sink block |
| connector settings / schedules | faucet.yaml + a schedule: block (or cron/CI) |
| incremental sync / CDC | resumable state: + CDC sources |
| dbt transformations | in-flight transforms: (or pair with dbt for in-warehouse modeling) |
Start from your first pipeline and the connector catalog.
