Comparison
AddisDB vs pgAdmin
The official PostgreSQL admin tool. One engine, free forever, and it knows that engine better than anything else here.
Engine breadth
How many database engines and data-file formats it can actually open.
pgAdmin — None
PostgreSQL only — plus Postgres-compatible engines by accident of the wire protocol. That is the entire point, and it is why it exposes Postgres internals nothing else does.
AddisDB — Strong
95 engines and data-file formats, from Postgres and MySQL through Mongo, Redis, Cassandra and Neo4j to Snowflake, BigQuery, ClickHouse and local CSV/Parquet/GeoJSON. Every engine is on every plan, including the free one.
Cost & openness
What it costs to use for real work, and whether you can read the source.
pgAdmin — Strong
Free and open source under the PostgreSQL Licence, with no paid tier at all. Nothing is held back.
AddisDB — Good
Free forever for databases on your own machine — the whole client, every engine, no account and no card. $49/year to reach databases that are not local; $99/user/year for teams; $299/user/year for SSO, audit log and RBAC. Source is not public.
Platform reach
Which operating systems and surfaces it runs on.
pgAdmin — Strong
Windows, macOS and Linux as a desktop app, plus a server mode you can host and use from a browser — the only tool here that does both well.
AddisDB — Strong
macOS, Windows and Linux as a native app, plus a CLI with a TUI and a VS Code extension that share the same core.
Production safety
What stands between you and the wrong statement on a production database.
pgAdmin — Limited
Role and permission management is excellent, but that is database-side administration. The client itself will happily run whatever you type.
AddisDB — Strong
Connections can be marked read-only; statements are classified before they run, so an unqualified DELETE or a DROP is stopped rather than reported afterwards. A prod environment tag adds write guards, and row-count thresholds catch the statement that would hit more rows than you meant.
AI capability
What the AI does, what it costs, and where your schema and keys go.
pgAdmin — None
None.
AddisDB — Strong
Plain-English to SQL, schema-aware, with the generated statement shown for you to edit before it runs. Bring your own provider key: it is stored in the OS credential store, calls go straight to your provider, and AI is included on the free tier because we are not the ones paying for the tokens.
Schema tooling
Diagrams, diffs, and getting a schema change from your laptop to production.
pgAdmin — Good
An ERD tool and a schema diff that produces a change script — both solid, both Postgres-only.
AddisDB — Strong
ERD of tables and foreign keys, schema diff between databases, and a migration preview that shows the exact SQL plus the dangerous parts — dropped columns, rewrites, locks — before anything runs. Reads Drizzle Kit and Prisma changes too.
The scoreboard
pgAdmin matches or beats AddisDB on: Cost & openness, Platform reach.
AddisDB comes out ahead on: Engine breadth, Production safety, AI capability, Schema tooling.
Which one to pick
Pick pgAdmin if…
You only use PostgreSQL. pgAdmin exposes more of Postgres than any general client will, it is free forever, and it runs in a browser if you want that.
Pick AddisDB if…
You touch anything other than Postgres, or you want guardrails and AI that pgAdmin has never set out to provide.
