Distributed SQL, one workbench.
Native SQL, schema, explain, and index tooling on the PostgreSQL driver surface — with backup/restore, migrations, multi-region visibility, and SSH tunneling for dedicated and self-hosted clusters.

// Distributed Hash Join · customers
Streams order rows to the 5 nodes holding customers ranges, hash joins locally, then returns. Distribution: full, vectorized.

What Mongrel ships for CockroachDB.
SQL editor & builder
Native SQL on the PostgreSQL wire protocol — full autocomplete, visual builder, and both sides stay editable.
EXPLAIN & DistSQL plans
Run EXPLAIN or EXPLAIN ANALYZE. Inspect distribution, span counts, vectorized stages, and row estimates per node.
Index & locality tools
Create indexes with STORING columns, review inverted and partial indexes, and see which queries each one serves.
Schema sync & migrations
Compare schemas across clusters, generate reversible migrations, and track online schema-change jobs to completion.
Multi-region topology
See ranges, replicas, and leaseholders per node and region. Spot follower reads and locality mismatches at a glance.
Backup & restore
Schedule BACKUP jobs to cloud storage, monitor job status, and run point-in-time RESTORE from the UI.
AI explain & rewrite
Paste a query and its EXPLAIN. The assistant rewrites it, proposes indexes and locality fixes, and shows the predicted plan.
Users, roles & certs
Browse users, roles, and grants. Connect with password or client-certificate auth; cluster status and statement stats built in.
SSH tunneling
Reach dedicated and self-hosted clusters behind a bastion. Key or agent auth, per-connection tunnel profiles.
