DBConvert Streams vs HeidiSQL

DBConvert Streams is a database IDE that also migrates data and runs continuous CDC across MySQL/MariaDB and PostgreSQL.

HeidiSQL is a free, lightweight Windows SQL client for MySQL/MariaDB, PostgreSQL, and SQL Server.

Quick answer

Choose by job

Choose DBConvert Streams if

  • You move data between MySQL/MariaDB, PostgreSQL, files, or S3 as a workflow.
  • Continuous CDC is part of the requirement, not an ad-hoc table copy.
  • You need source/target validation after a migration.
  • You want a self-hosted Docker option, not a Windows desktop client only.

Choose HeidiSQL if

  • You want a fast, free, lightweight client for everyday SQL on Windows.
  • You browse and edit tables and run queries across a few engines.
  • Occasional server-to-server table copy covers your data-movement needs.
  • Continuous CDC and migration validation are not part of the requirement.

AI and MCP

The AI difference

DBConvert Streams

DBConvert brings AI into everyday SQL and data inspection while connecting that work directly to guided migration, validation, and continuous replication.

Where DBConvert Streams goes further

Run migration as a workflow, not an ad-hoc copy

Load mode moves data between MySQL/MariaDB, PostgreSQL, files, and S3 with table mapping and filters — repeatable, not a one-off table copy.

Keep the target in sync after the load

MySQL binlog and PostgreSQL logical replication captured continuously, with checkpointed state and resume. HeidiSQL has no CDC.

Validate the cutover before declaring it done

Compare row counts and sample content between source and target. HeidiSQL has no comparison view.

See every replication run live

Stream Monitor shows throughput, lag, and run history. HeidiSQL has no run history.

Work from any OS, not just Windows

HeidiSQL runs natively on Windows only (elsewhere via Wine). DBConvert Streams runs as a desktop app on Linux, macOS, and Windows, and as a Docker distribution — the same migration and CDC workflow regardless of platform.

Where HeidiSQL wins

Stay fast and lightweight

Small footprint, quick startup, low ceremony — a long-standing favorite for everyday SQL on Windows. This is its real edge.

Cover the common engines in one client

MySQL/MariaDB, PostgreSQL, and SQL Server connections in a single familiar UI.

Copy tables between servers ad hoc

A built-in server-to-server table copy handles quick one-off transfers without another tool.

Start free, no licensing decision

GPL, no tiers — the full client is free.

Low learning curve

A straightforward UI that developers pick up immediately for browse-and-query work.

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

Workflow

Turn an ad-hoc table copy into a validated, continuously synced migration

  1. 1Connect source and target in Data Explorer and inspect schemas side by side.
  2. 2Run a Load-mode stream with table mapping and filters instead of a one-off copy.
  3. 3Open the Compare tab and verify row counts and sample rows on the target.
  4. 4Switch the stream to CDC mode to capture and apply ongoing source changes.
  5. 5Watch progress in Stream Monitor — throughput, lag, and run history.

HeidiSQL can copy a table between servers once. DBConvert Streams runs the migration as a repeatable workflow, validates it, and keeps it in sync.

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 HeidiSQL replacement?

No. They solve different jobs.

  • HeidiSQL — A lightweight client for everyday SQL and table browsing.
  • DBConvert Streams — A migration and CDC tool with an IDE on top.

Keep HeidiSQL for fast SQL work on Windows; use DBConvert Streams when data has to move as a workflow or stay in sync.

HeidiSQL can copy tables between servers — is that the same as migration?

For a one-off copy it can be enough. It is not repeatable with mapping and filters, has no source/target validation, and no ongoing sync. DBConvert Streams runs migration as a configurable workflow with Compare and CDC.

Does HeidiSQL support change data capture?

No. HeidiSQL has no CDC. For continuous replication you need a separate tool. DBConvert Streams provides log-based CDC for MySQL and PostgreSQL out of the box.

Is DBConvert Streams as lightweight as HeidiSQL?

They have different scopes. HeidiSQL is a minimal client; DBConvert Streams is a migration/CDC product with an IDE. For pure browse-and-query speed on Windows, HeidiSQL stays lighter.

When should I not use DBConvert Streams?

When you only need a fast, lightweight client for browsing and querying with at most an occasional table copy. In that case HeidiSQL is a better fit.
