Mongrel
Mongrel is a desktop database systems workbench that unifies 30+ database engines, terminals, file transfer, containers, Kubernetes, and an API client in one native app for Windows, macOS, and Linux.
Query PostgreSQL, MySQL, MongoDB, SQL Server, Oracle, Redis, ClickHouse, Snowflake, BigQuery, and more in native SQL or engine dialects. Edit data inline, drill through foreign keys, run EXPLAIN plans, design schemas on a visual ER canvas, sync data between databases, and schedule encrypted backups. Built-in SSH/Mosh/Telnet/Serial terminals, SFTP/SCP file transfer, Docker and Podman management, Kubernetes operations, and an HTTP/GraphQL/WebSocket/gRPC client replace a stack of tools.
An opt-in AI assistant supports OpenAI-compatible, Anthropic, and Gemini providers, with keys in your OS keychain and writes always approval-gated. Mongrel is local-first: your queries, data, and logs never leave your machine. All plans include every feature; start with a 7-day trial, no card required.

DbGate
DbGate is a cross-platform SQL + NoSQL client that runs on Windows, macOS, Linux as desktop app, or in Docker - and then entirely in your browser.
It has very powerful data browser, which allows you to quickly find or modify, what you need, even when using complicated relations. There are many filtering options allowing you in few clicks define quite complex conditions.
You could of course use classical SQL editor with code completion or query designer. DbGate also has capability of design queries on NoSQL databases and event join results with SQL databases.
Database compare tool is very fast, as it uses already cached DB models. You could browse and filter objects by type (table, view, procedure function) and by comparing status (equal, changed, added, removed). You could also deploy changes to database.
Quite new feature is DbGate Cloud - online storage for connections and SQL scripts. You could also share folders with connections with others, with role-base permission access.

FluentDB
FluentDB is a native, AI-first database client for Apple Silicon Macs that combines a schema-aware copilot, a modern SQL editor, a keyboard-first explorer, fast data tables, and built-in safety controls in one focused workspace. It connects to PostgreSQL, MySQL, SQLite, and Microsoft SQL Server, letting users ask questions in plain English and receive SQL written against their real tables and columns. By default, the AI reads the schema rather than row data, never runs a statement on its own, and asks for approval before write queries execute. Read-only connections, local query history, server-side cancellation for runaway queries, and visible SQL keep users in control. The editor provides schema-aware autocomplete, formatting, saved queries, instant previews, and seamless switching between manual SQL and AI mode without losing context. Command + P opens tables, views, functions, sequences, types, and extensions, while the native grid can smoothly scroll, edit, sort, copy, and export.

DbSchema
DbSchema is for visual designing the schema in a team, deploy and document the schema. Other integrated features like data explorer, visual query editor, data generator, etc., makes DbSchema an every-day tool for everybody who interacts with databases. DbSchema supports all relational and No-SQL databases, including MySQL, PostgreSQL, SQLite, Microsoft SQL Server, MongoDB, MariaDB, Redshift, Snowflake, Google and more. DbSchema is reverse-engineering the database schema from the database and visualize it as diagrams. You will interact with the database using diagrams and visual tools. DbSchema model is using its copy of schema structure, independent from the database. This allows the schema deployment on multiple databases, save the design model to file, store it in GIT and design the schema in a team, design the schema without database connectivity, compare different versions of the schema and generate SQL migration scripts.
