The MySQL Workbench alternative for engineers past the single-engine wall.
Mongrel is a MySQL Workbench alternative for engineers who have outgrown a MySQL-only tool: it keeps MySQL and MariaDB in the mix while adding 30+ database engines, full SSH terminals, SFTP/SCP, Kubernetes and Docker tooling, and an API client in one desktop app. MySQL Workbench is free, open source, and excellent at visual schema design; Mongrel's distinction is the wider systems workbench around the database layer.

// Why teams switch
Where MySQL Workbench stops and Mongrel keeps going.
MySQL Workbench is a purpose-built tool for MySQL, and it does that job well: SQL editing, server administration, and EER diagram modeling in a free package. The friction starts when the work spreads, a second engine appears, a jump host stands between you and the server, a schema lives in a Kubernetes cluster, or the API beside the database needs testing. Mongrel covers that whole trail in one app instead of asking you to assemble it from separate tools.
// What ships
What Mongrel adds around the database work.
30+ database engines
MySQL and MariaDB alongside PostgreSQL, SQLite, Redis, MongoDB, Oracle, SQL Server, ClickHouse, and more, delivered as signed first-party plugins with support varying by engine.
Full SSH terminal
SSH, Mosh, Telnet, Serial, and local shells with logging, triggers, quick commands, broadcast, and session recording, beside your database work.
Database tunnels and jump hosts
Per-connection database tunneling where supported, plus SSH terminal profiles with jump-host chains, key files, agent auth, and port forwarding.
SFTP and SCP file transfer
Dual-pane SFTP and SCP transfers with recursive operations, streaming progress, and cancellation, for moving dumps and config files to and from the server.
Kubernetes and Docker
A Kubernetes GUI with pods, services, RBAC, events, logs, exec, port-forward, Helm, and CRDs, plus full Docker and Podman lifecycle management.
API client built in
HTTP, GraphQL, WebSocket, and gRPC requests with environments, OAuth, mTLS, and cURL, Postman, and Insomnia import, next to the data they touch.
// Side by side
Mongrel vs MySQL Workbench, feature for feature.
| Capability | Mongrel | MySQL Workbench |
|---|---|---|
| Price and license | Commercial; $99/year individual with a free 7-day trial, no card required | Free and open source under the GPL, maintained by Oracle |
| Database coverage | 30+ engines across relational, document, key-value, and search systems, with MongoDB and MongrelDB built in | Focused on MySQL, with MariaDB compatibility |
| Visual schema design | Not a core Mongrel surface; the focus is query work and the systems workbench around it | EER diagram modeling and visual schema design |
| SSH and terminals | Database tunnels plus full SSH, Mosh, Telnet, Serial, and local terminal profiles with jump-host chains | Connection options for reaching MySQL servers, not a general terminal |
| Kubernetes and Docker | Built-in Kubernetes GUI and Docker/Podman management | Not part of MySQL Workbench |
| Platforms | Linux x86-64, macOS Apple silicon, Windows x64 and ARM64 | Cross-platform desktop app for Linux, macOS, and Windows |
// Honest tradeoffs
Where MySQL Workbench still has the edge.
MySQL Workbench is free and open source, and Mongrel is not; that alone settles the question for many teams. Its visual schema modeling and EER diagram design are genuinely strong, and Mongrel does not offer an equivalent. And if your world really is MySQL only, a purpose-built tool from the same ecosystem that ships the database is a reasonable place to stay. Mongrel earns its price when the work spans engines and systems, so use the 7-day trial to verify the exact databases and workflows your team needs.
// FAQ
Frequently asked questions.
Is MySQL Workbench free?
Yes. MySQL Workbench is free and open source under the GPL and is maintained by Oracle. Mongrel is commercial software at $99/year for individuals, with a free 7-day trial that requires no credit card.
Does MySQL Workbench support PostgreSQL or other databases?
No. MySQL Workbench is focused on MySQL, with MariaDB compatibility. Mongrel supports 30+ database engines as signed first-party plugins, including PostgreSQL, MySQL, SQLite, Redis, MongoDB, Oracle, SQL Server, and ClickHouse, with support varying by engine.
MySQL Workbench vs Mongrel: which should I choose?
Choose MySQL Workbench when you administer a MySQL-only environment and want free, purpose-built tooling with strong visual schema modeling. Choose Mongrel when you work across many database engines and also want terminals, SFTP/SCP, Kubernetes, Docker, and an API client in the same app.
Does Mongrel have visual schema design like MySQL Workbench's EER diagrams?
No, and it is worth being direct about that. MySQL Workbench's EER modeling and visual schema design are genuinely strong, and Mongrel does not replicate them. Mongrel's distinction is breadth of engines plus the systems workbench of terminals, file transfer, containers, and API tooling around the database work.
Is Mongrel open source?
No. Mongrel is a commercial product with a native Tauri/Rust desktop shell, OS keychain secret storage, an optional master password, and no telemetry. VisorCraft maintains open-source projects separately, including MongrelDB.
