Query any database without switching apps.
A full database client, built into your API tool. Write SQL, ask questions in plain English, visualize your schema, and diff migrations — all alongside your API requests.
7 databases supported
Full Postgres support including JSONB, arrays, CTEs, and PL/pgSQL stored procedures.
MySQL 5.7+ and MariaDB 10.4+. Stored procedures, views, triggers, and full-text search.
Open local .db files directly. No connection string needed — just browse to the file.
Document queries, aggregation pipeline builder, index management, and Atlas support.
Key-value browsing, TTL management, pub/sub monitoring, and Lua scripting.
Analytical queries at scale. Full SQL support with ClickHouse-specific functions.
AWS DynamoDB via SDK. Table browser, PartiQL queries, and GSI/LSI inspection.
Built for the way developers actually work
NLP → SQL
Type a question in plain English — "show me all orders from last week with total above $500" — and Rostyman generates the SQL query automatically. Powered by your AI provider of choice.
Query Editor
Monaco editor with SQL syntax highlighting, autocomplete from your schema, multiple result tabs, query history, and a one-click formatter (Ctrl+Shift+F).
ER Diagram
Auto-generated entity-relationship diagram from your foreign keys. Interactive — click a table to highlight its connections. Export as PNG.
Schema Diff
Compare two databases or two snapshots of the same schema. Visual diff highlights added, removed, and modified tables/columns. Generate migration SQL automatically.
EXPLAIN Panel
Run EXPLAIN ANALYZE on any query and see the execution plan visualized per dialect — Postgres, MySQL, SQLite, and MongoDB all render differently.
DB Projects (3-level hierarchy)
Organize connections in a Project → Group → Connection tree. Connections can be added at any level — no forced structure. Drag-and-drop to reorganize.
Inline Cell Editing
Double-click any cell in a query result to edit it. Changes generate preview SQL (UPDATE/INSERT/DELETE) before executing. Full undo support.
Query Variables
Parameterized queries with named variables — {{user_id}}, {{start_date}}. Injection-safe, with a variable editor panel for easy input.
Production-safe by default
Destructive query safety
Any DELETE, DROP, or TRUNCATE on a connection marked "production" requires typing the table name to confirm. Protects against accidental data loss.
SSH tunnel support
Connect to databases behind firewalls via SSH bastion hosts. Key-file and password auth. Works with all 7 supported databases.
Auto-reconnect
Connections dropped due to idle timeout, network blip, or server restart are automatically re-established with exponential backoff.
Get notified when it ships
Join the waitlist and we will email you the moment the database client is available.
No spam. One email when it launches. That's it.
