Why Jam SQL Studio for Oracle?
Oracle developers deserve a modern, cross-platform IDE with deep Oracle support. Here is what sets Jam SQL Studio apart.
PL/SQL Debugger
The only cross-platform step-through debugger for Oracle stored procedures. Set breakpoints, inspect variables, navigate the call stack, and evaluate expressions on Mac, Windows, and Linux.
No Client Install
Connect directly to Oracle without installing Oracle Client, Instant Client, or configuring TNS files. Just enter the host, port, and service name.
Tablespace Manager
Visual storage management without Enterprise Manager. View tablespace usage, datafile details, and manage storage from a lightweight desktop app.
AI-Native
Built-in MCP server (Model Context Protocol) and AI Workspace for AI-assisted Oracle development. Claude Code, OpenCode, and Codex CLI can safely query your Oracle databases under your AI policy.
