Visual PostgreSQL GUI for JSONB, ER Diagrams and EXPLAIN

Postgres Has the Richest Feature Set, and the Densest Output

JSONB blobs in a single cell, EXPLAIN walls of text, and foreign keys buried across many schemas slow down exploration, query tuning, and debugging.

JSONB and arrays are unreadable in a cell

Nested jsonb, text[] arrays, and hstore collapse into one clipped column, so you paste them elsewhere just to read or edit them.

EXPLAIN output is a wall of text

Sequential scans, bad join orders, and off-by-1000x row estimates are hidden inside dense planner output that is hard to read from text alone.

Schemas and foreign keys stay hidden

Tables spread across many schemas and the search_path, with relationships defined only by foreign keys you cannot see at a glance.

VisuaLeaf visual workspace

A JSONB tree editor, ER diagrams drawn from real foreign keys, visual EXPLAIN plans, schema compare, and charts, all in one clean Postgres workspace.

Built Around What Makes PostgreSQL PostgreSQL

JSONB, custom types, CTEs, materialized views, EXPLAIN, and extensions like PostGIS and pgvector, explored, queried, and visualized instead of parsed from text.

Table Management

Manage tables visually instead of hand-writing DDL. Add, rename, and edit columns with their types, defaults, primary keys, and foreign keys, then work across tabbed panels for triggers, constraints, partitions, and storage. Hit Show DDL to read the full CREATE TABLE statement any time.

JSONB Tree & Editor

Expand jsonb, json, and array columns in a nested tree, filter with the ->, ->> and @> operators against GIN indexes, and edit nested values without hand-writing jsonb_set.

ER Diagrams from Foreign Keys

Auto-draw an interactive ER diagram from your real foreign keys and constraints, spanning multiple schemas plus views and materialized views, then drill into triggers, constraints, partitions, index DDL, and CREATE statements.

A Visual Workflow for Everyday PostgreSQL Tasks

VisuaLeaf connects the steps Postgres users usually handle separately: connect to any instance, explore schemas and JSONB, build SQL, profile with EXPLAIN, and visualize.

Connect

Reach local, Docker, or managed Postgres, RDS, Aurora, Cloud SQL, Supabase, Neon, over SSL or an SSH tunnel.

VisuaLeaf browsing PostgreSQL schemas, tables, and JSONB columns in a tree

Explore

Browse schemas and the search_path, tables and views, and expand JSONB and array columns in a tree.

Build

Assemble JOINs, CTEs, and window functions visually, or drop into the SQL editor with autocomplete.

Built for Different PostgreSQL Users

Whether you model data in JSONB, tune a slow plan, review roles and Row-Level Security, or learn SQL, VisuaLeaf gives you a clearer way to work with Postgres.

Developers

Model data with JSONB, arrays, ENUMs, and custom types, and debug the SQL your app runs against real rows.

DBAs and Data Teams

Compare schemas, review roles, privileges, and Row-Level Security, and profile EXPLAIN plans across environments.

Data Analysts

Write CTEs and window functions, query JSONB, and chart the results without a separate BI pipeline.

Students and Beginners

Learn Postgres visually, see foreign keys as ER diagrams and turn the query builder into readable SQL.

Frequently Asked Questions

What makes VisuaLeaf a good GUI for PostgreSQL specifically?

VisuaLeaf is built around the features that make Postgres distinctive. You can expand JSONB and array columns in a tree instead of a cramped cell, browse multiple schemas and the search_path, auto-generate ER diagrams from real foreign keys, build SQL with CTEs and window functions, and read EXPLAIN as a visual plan rather than raw text.

Can I view and edit JSONB and JSON columns visually?

Yes. VisuaLeaf renders JSONB and json columns as an expandable tree so you can inspect nested keys, arrays, and hstore-style data inline, edit values without hand-writing jsonb_set, and it recognizes GIN-indexed columns you filter with the ->, ->> and @> operators.

Can I use VisuaLeaf with managed PostgreSQL like RDS, Supabase, or Neon?

Yes. VisuaLeaf connects to self-hosted PostgreSQL over SSL or SSH tunnels, and to managed services including Amazon RDS, Aurora, Google Cloud SQL, Supabase, and Neon. Extensions such as PostGIS, pg_trgm, uuid-ossp, and pgvector are detected on connect.

Does the visual query builder support CTEs, window functions, and JOINs?

Yes. The visual builder covers SELECT, WHERE, JOIN, GROUP BY, ordering, and limits, and understands PostgreSQL constructs like WITH (CTE) blocks, window functions, ENUMs, ranges, and custom types. Every query has an export-to-SQL button, so you keep clean, editable Postgres SQL.

Can I generate ER diagrams from my PostgreSQL schema and foreign keys?

Yes. VisuaLeaf reads foreign keys, primary keys, and constraints from the information_schema to auto-draw an interactive ER diagram across schemas, including views and materialized views, so you can drill into tables, columns, and relationships.

Can VisuaLeaf visualize EXPLAIN query plans?

Yes. VisuaLeaf turns EXPLAIN into a visual plan tree with node-level cost and row estimates, so you can spot sequential scans, bad join orders, and missing indexes without parsing raw planner output.

Can I manage roles and privileges and monitor live activity?

Yes. VisuaLeaf includes a user-management dashboard for Postgres roles: list, create, alter, and drop roles, grant and revoke role membership, grant and revoke table and schema privileges, and see where Row-Level Security applies. For live activity, it shows active connections and currently-running queries from pg_stat_activity, surfaces slow queries and query profiling from pg_stat_statements, and reports per-table statistics.
