SQLsaber - Open-source agentic SQL assistant

SQLsaber

SQLsaber is an open-source agentic SQL assistant. Think Claude Code but for SQL.

Ask questions about your data in plain English. SQLsaber writes SQL queries, executes them, and explains the results.

SQLsaber reads your schema, writes SQL, executes it, and explains the results—all from a single natural language prompt.

$ saber "How many orders were placed last month?"

# SQLsaber will:
# 1. Discover relevant tables (orders, order_items, etc.)
# 2. Analyze their schema
# 3. Generate and run SQL
# 4. Return results with explanation

Why SQLsaber?

• No context switching — Stay in your terminal, ask questions, get answers
• Schema-aware — Automatically introspects your database; no manual setup
• Safe by default — Read-only queries; won't modify your data
• Works with your stack — PostgreSQL, MySQL, SQLite, DuckDB, and CSV files

Install

# Recommended
uv tool install sqlsaber

# Or with pipx
pipx install sqlsaber

Then run:

saber

On first launch, SQLsaber walks you through connecting a database and setting up authentication.

Quick Examples

# Interactive mode

Change AI model

saber models set

Add knowledge (searchable KPI/query references)

# Add a structured knowledge entry
saber knowledge add "Revenue KPI" "Recognized revenue from shipped orders only" --sql "SELECT SUM(amount) FROM orders WHERE status = 'shipped'" --source "finance-wiki"

# Long description/SQL from files
saber knowledge add "Revenue definition" "$(cat ./knowledge/revenue_definition.md)" --sql "$(cat ./sql/revenue.sql)"

# Search saved knowledge
saber knowledge search "revenue shipped orders"

How It Works

1. Discovery — Lists tables and identifies relevant ones based on your question
2. Schema analysis — Introspects only the tables needed
3. Query generation — Writes SQL tailored to your database dialect
4. Execution — Runs read-only queries with safety checks
5. Results — Formats output with explanations
