Talk to your data.
Ship schema changes safely.
Query any database in plain English. Diff schemas across environments. Push migration PRs to GitHub — with write confirmation gates and one-click rollback.
Works with your database
"Show me active users in EU region who signed up last week, grouped by plan."
FROM users
WHERE region = 'EU'
AND created_at >= NOW() - INTERVAL '1 week'
AND status = 'active'
GROUP BY plan;
Intelligence meets Control
LeafSQL doesn't just guess code. It understands your database topology, enforcing constraints and safety policies before execution.
Context-Aware Intelligence
Understands your database structure—tables, relationships, and constraints. Knows that user_id links orders to users.
Safe Mutation & Rollback
Write operations are wrapped in transactions. Preview impacted rows before committing, or auto-rollback on non-production environments.
Under the hood
Built for Production Reliability
LeafSQL handles the complexity of evolving schemas so your team never has to worry about broken queries or silent data drift.
Background Schema Adaptation
Schema changes are detected and reconciled automatically as they happen. Your queries stay valid, your context stays fresh — and nothing in your workflow ever needs to pause.
Drift Event Handling
When staging and production diverge, LeafSQL surfaces every difference — added columns, dropped indexes, type mismatches — and puts the resolution decision in your hands.
Graph-Powered Low Latency
Foreign-key relationships are modelled as graph edges, not rows. Traversing complex multi-hop relationships takes microseconds — not the stacked round-trips of traditional joins.
The Modern Data Workflow
LeafSQL is more than a query tool. It's a complete workspace that brings engineering best practices—like version control and impact analysis—to your database management.
Version Control for Your Database
Compare environments and generate pull requests with migration SQL—no manual diff-writing required.
Smarter Than Schema-Aware
LeafSQL maps the web of relationships between your tables. Deleting `users` breaks `orders`.
