FlexTable is a native desktop database client that puts SQL and NoSQL in one editor. It came out of a simple frustration: working across several databases usually means keeping TablePlus open for SQL, Compass for Mongo and RedisInsight for Redis and switching between them all day, and many of those clients are heavy Electron or JVM apps that quietly phone home on top of it. FlexTable pulls all of that into one window and tries to stay light and private instead.

Key features:

• One editor for every engine: SQL and T-SQL, a real shell-syntax editor for MongoDB, and a Redis command editor, each with its own autocomplete.
• An AI assistant that runs on your own API key and calls the provider directly, so nothing passes through our servers.
• Native and around 25 MB rather than an Electron bundle, with no telemetry and credentials that never leave your machine.
• Query results as a fast virtualized grid for large tables, a chart built straight from the query, or a full multi-format view of a single cell.
• Staged edits that let you preview the exact SQL and roll back cell by cell before anything is committed.

It is built for backend and full-stack developers and data engineers who move between many databases in a day, especially when SQL and NoSQL sit side by side, and today it connects to eleven of them: PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, SQLite, CockroachDB, Amazon Redshift, ClickHouse, MongoDB and Redis. There are builds for macOS (Intel and Apple Silicon), Windows and Linux (deb, AppImage, rpm); you download it from flextable.dev and install it like any other app, and it is free during the beta, with the first 500 people able to claim a lifetime PRO key with no card at flextable.dev/early-access.

Most clients make you pick a side: TablePlus is native and light but SQL only, while DBeaver and DataGrip reach more engines but run on the JVM and feel heavy. FlexTable tries to sit in between, native and cross-platform, and it treats NoSQL as a first-class citizen with a genuine MongoDB shell and Redis command editor rather than a read-only browser.
