A Self-Hosted Fivetran Alternative: DBConvert Streams vs Fivetran

DBConvert Streams is a self-hosted database-to-database migration and CDC tool with a built-in IDE.

Fivetran is a managed, cloud-only ELT platform that moves data from SaaS apps and databases into a data warehouse.

Quick answer

Choose by job

Choose DBConvert Streams if

  • Your work is moving and synchronizing operational data, not analytics ingestion.
  • Self-hosting is part of the requirement — compliance, data residency, or cost.
  • Your stack centers on MySQL/MariaDB, PostgreSQL, files, or S3.
  • You want predictable license pricing, not usage-based row metering.

Choose Fivetran if

  • Your work is loading SaaS apps and databases into an analytics warehouse.
  • You want infrastructure managed for you — SLAs, monitoring, support included.
  • Your team is comfortable with SaaS data handling and a vendor cloud.
  • Your downstream stack runs on dbt; you want transformations in the same pipeline.

AI and MCP

The AI difference

DBConvert Streams

DBConvert ships the AI and MCP surfaces with the product itself, aimed at investigating live databases, validating moves, and diagnosing replication.

Explore DBConvert AI and MCP

Fivetran

Fivetran Activations has AI Columns for row-level LLM enrichment. Fivetran also published a customer architecture that wraps its REST API in an MCP server with approvals and audit records.

What to know: The MCP example is a customer-built solution architecture, not a verified native Fivetran MCP product or a live source-database SQL assistant.

Where DBConvert Streams goes further

Keep data inside your environment

Self-contained desktop app or Docker distribution in your own VPC, on-prem, or laptop. Data and credentials never touch a vendor cloud.

Inspect data inside the same product that moves it

Browse schemas, run SQL, inspect ER diagrams alongside the replication. Fivetran assumes a separate SQL client.

Write directly to the target database, no warehouse hop

CDC and Load mode write straight to the target — useful for operational migration and homogeneous sync, not warehouse ingestion.

CDC happens as the source writes

MySQL binlog and PostgreSQL logical replication captured natively, with checkpointed state and resume. No HVR add-on, no per-source configuration overhead.

Pay by license, not by row volume

Predictable cost. Pricing does not scale the way Fivetran MAR billing does — for high-volume sync the gap can be significant.

Read and write files and S3 like a database

CSV, JSONL, and Parquet are real source and target types — not just staging for warehouse loading.

Where Fivetran wins

Add a SaaS source in minutes of clicks

Pre-built connectors with managed auth, schema drift handling, and incremental updates. New source onboarding is config, not engineering time.

Hand operations to the vendor

No infrastructure to run. SLAs, monitoring, alerting, and 24/7 support are part of the subscription.

Land data in a warehouse at enterprise scale

Type handling, normalization, replication models, and downstream materialization for Snowflake, BigQuery, Redshift, Databricks.

Handle high-volume DB replication via HVR

The HVR engine (acquired by Fivetran) handles demanding database replication scenarios that pure connector-based ELT does not.

Run dbt as part of the same pipeline

Fivetran owns dbt — transformations live in the same managed stack, not a separate tool to stitch in.

See it on your own databases — self-hosted, free evaluation, no credit card.

Workflow

Move data between operational databases without sending it through a SaaS pipeline

  1. 1Deploy DBConvert Streams as a desktop app or Docker distribution inside your own VPC, on-prem, or laptop.
  2. 2Add source and target connections (e.g., production MySQL and a PostgreSQL replica) — credentials never leave your environment.
  3. 3Run a Load-mode stream with table mapping and filters; the data flows directly between the two databases.
  4. 4Open the Compare tab and validate row counts and sample data on the target.
  5. 5Switch to CDC mode and monitor throughput, lag, and run history in Stream Monitor.

Fivetran would route the same data through their cloud and into a warehouse. DBConvert Streams runs in your environment and writes directly into the target database.

Also supported

The same workflow runs for other source/target combinations:

  • PostgreSQL → MySQL/MariaDB (reverse direction, Load + CDC)
  • MySQL/MariaDB ↔ MySQL/MariaDB (homogeneous replication)
  • PostgreSQL ↔ PostgreSQL (homogeneous replication)
  • MySQL/PostgreSQL → files (CSV, JSONL, Parquet)
  • MySQL/PostgreSQL → S3-compatible storage
  • Files / S3 → MySQL or PostgreSQL

FAQ

Frequently asked questions

Is DBConvert Streams a Fivetran replacement?

No. They solve different jobs.

  • Fivetran — Managed SaaS ELT for moving data from many sources into a data warehouse.
  • DBConvert Streams — Self-hosted database-to-database migration and CDC with a built-in IDE.

Teams loading Salesforce or Stripe into Snowflake pick Fivetran. Teams replicating MySQL/PostgreSQL on their own infrastructure pick DBConvert Streams.

Can I self-host Fivetran?

No. Fivetran is cloud-only — there is no self-hosted distribution. If self-hosting is a hard requirement (compliance, data residency, cost control), DBConvert Streams is a fit: it ships as a self-contained desktop app and a Docker distribution.

Does DBConvert Streams have SaaS connectors like Fivetran?

No. DBConvert Streams focuses on databases (MySQL/MariaDB, PostgreSQL), files, and S3-compatible storage as sources and targets. For SaaS-to-warehouse ingestion (Salesforce, Stripe, HubSpot, and similar), use Fivetran or Airbyte.

Which is better for direct database replication (MySQL, PostgreSQL, files, S3)?

DBConvert Streams, for operational use cases.

  • Fivetran — Can replicate databases (HVR-based for high volume) but is shaped around warehouse delivery and cloud-only operation.
  • DBConvert Streams — Native log-based CDC, direct DB-to-DB write, source/target comparison, and files/S3 as first-class endpoints — all self-hosted.

Use Fivetran if the replication ends in a warehouse and you want it fully managed. Use DBConvert Streams for direct operational replication you run yourself.

How does pricing compare?

Different models. Compare against your actual data volume and use case.

  • Fivetran — MAR (Monthly Active Rows) — usage-based. Cost scales with the number of unique rows touched per month and can grow quickly at scale.
  • DBConvert Streams — License-based: evaluation Load marks text outside table keys and relationships after 50 rows per table, and CDC runs for 2 hours. Cost does not scale with row volume.

For high-volume sync, the gap can be significant; for small/medium workloads, Fivetran can be the simpler choice operationally.

When should I not use DBConvert Streams?

When your job is SaaS-to-warehouse ingestion, you need 500+ connectors, or you want a fully managed pipeline with vendor SLAs. In those cases Fivetran (or Airbyte Cloud) is a better fit.
