Make PostgreSQL Legible, From JSONB to EXPLAIN

PostgreSQL gives you JSONB, custom types, partitions, and an extension for everything — then hides all of it behind catalog queries and a plain-text execution plan. VisuaLeaf turns a Postgres database into a visual workspace: open JSONB as a tree, draw ER diagrams from real foreign keys, read EXPLAIN as a plan you can follow, and chart what a query returns.

JSONB columns arrive as one long string

A jsonb payload prints as a single flat blob, so nested keys and arrays have to be unfolded by hand before you can see what a row actually holds.

EXPLAIN output is a wall of text

Nested loops, sequential scans, and cost estimates are buried in indented plan text, which makes it slow to find the one node where a query falls apart.

Foreign keys never draw themselves

Relationships live in constraint definitions spread across the system catalogs, so the shape of the schema exists only in the head of whoever last worked on it.

Objects sprawl across schemas and extensions

Views, materialized views, functions, and extension-owned tables pile up along the search path, and the shell gives you no single place to see what exists.

A visual workflow for PostgreSQL development

Browse and edit JSONB as a tree, build queries visually or in SQL, map foreign keys into an ER diagram, read execution plans, and chart results — all in one 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.

Built by Developers, For Developers

VisuaLeaf is made by an independent software studio that ships often and listens to the developers who use it every day.

Independent studio — Built and maintained by a small, focused team — not bolted onto a larger enterprise suite.
Active development & regular releases — New features, fixes, and improvements ship on a steady cadence, not once a year.
Shaped by community feedback — Feature requests and bug reports from real users directly influence the roadmap.
Used by developers worldwide — Developers, DBAs, and data teams rely on VisuaLeaf to work with their databases visually.
Truly cross-platform — Native builds for Windows, macOS, and Linux, so your whole team works in the same tool.
One tool, many databases — MongoDB, PostgreSQL, MySQL, SQLite, MariaDB, SQL Server, and more in a single workspace.
