Calíope — Database Client for Mac, iPad and iPhone Calíope is a powerful, native client for MySQL, MariaDB, Amazon Aurora, PostgreSQL, SQL Server, Oracle, ClickHouse and Redis, built for Mac, iPad and iPhone. Whether you're a developer, DBA, or data analyst, Calíope gives you everything you need to connect, query, explore, and manage your databases — all in a clean, native interface designed for Apple platforms. WHAT'S INCLUDED WITH CALÍOPE PRO SQL Editor — Write and execute queries with syntax highlighting and an integrated execution history, side by side across independent tabs, each with its own live session. Reports — A saved query with its parameters declared and its output defined: which columns, in what order, with what titles and formats. Running it twice gives the same thing. Works against relational databases, SQLite files and MongoDB, exports to nine formats including a paginated PDF, and can run on a schedule. Database Explorer — Browse your full schema — tables, views, stored procedures, triggers, events and more — from an intuitive tree, with columns, indexes and foreign keys at a glance. ER Diagrams — Visualize your database structure with interactive entity-relationship diagrams. Understand table relationships and schema design without writing a single query. Secure Connections — Connect to remote servers safely with native SSH tunneling (ed25519 and ECDSA keys), SSL/TLS encryption, and per-profile credential storage in your system Keychain. Scheduled Backups — Automate backups with flexible scheduling and configurable retention, choosing exactly which databases and tables go into each job. Replication Topology — Declare the primary and its replicas, and see the whole group at once, with a diagram: each replica with its lag, its two threads and the transactions it actually owes. A replica can report 0 seconds while it runs hours behind. Multiple Sessions & Query Log — Open and switch between independent database sessions, each isolated. Every query is logged locally, so you can trace what was executed, when, and on which connection. Works without a server — A built-in SQLite editor for local .sqlite files: structure, data, SQL, pragmas, Save/Revert and CSV/JSON/SQL import and export. A DuckDB editor opens .duckdb files and queries Parquet, CSV or JSON where they already are. Plus a read-only previewer for .md, .sql, .json, .csv, .rtf and .log files. All work offline. Widgets — Server metrics without opening the app: Mac desktop, iPhone and iPad Home and Lock Screens. One server per widget; tap to open its dashboard. AI SQL Assistant — An optional assistant that helps you write queries, explain results and suggest optimizations. It works from the first launch with Apple Intelligence: no key, no cost, and nothing leaves your device. You can also bring your own key from a supported provider — usage is billed by that provider, and Calíope does not charge for or resell AI services — or point it at a local model. Keys stay in your Keychain. ONE-TIME PURCHASE • Calíope Pro — buy once, keep forever.
