Oracle SQL

       DECODE(status, 1, 'Active', 'Inactive')
FROM   employees
WHERE  ROWNUM <= 10;
PostgreSQL
SELECT COALESCE(name, 'Unknown'),
       CURRENT_TIMESTAMP,
       CASE WHEN status = 1 THEN 'Active'
            ELSE 'Inactive' END
FROM   employees

Changes:+ NVL → COALESCE+ SYSDATE → CURRENT_TIMESTAMP+ DECODE → CASE WHEN+ ROWNUM → LIMIT

Why SteinDB

Built for database engineers who need correctness, not guesswork.

Bidirectional

Oracle to PostgreSQL AND PostgreSQL to Oracle. The only tool that does both directions with deterministic accuracy.

Rules + AI

90%+ handled by deterministic rules with >99% accuracy. AI fills the gap for the hard 10% — bring your own API key.

Enterprise Ready

Team collaboration, role-based access control, audit logging, Stripe billing, and 18 languages out of the box.

Open Source CLI

pip install steindb. Free, offline, no signup required. Convert files, scan schemas, generate reports from your terminal.

How It Works

Three steps from Oracle to PostgreSQL (or the other way around).

1

Paste SQL

Paste your Oracle PL/SQL, DDL, or DML into the playground editor or pipe it through the CLI.

2

Convert

The rule engine converts deterministically. Anything it cannot handle with >99% confidence goes to AI.

3

Deploy

Get verified PostgreSQL output with confidence scores, change logs, and warnings — ready for production.
