Best Free Database Tools in 2026 (Actually Free, Tested)

Free database tools fall into two categories: tools that are free forever with real functionality, and tools with crippled trials dressed up as free tiers. This list covers only the first category. Every tool here was checked against current pricing and feature pages in June 2026. "Free" means no credit card required, no expiry date, and enough functionality to do real work.

Quick Comparison

DBeaver Community

DBeaver Community is the closest thing to a free database workbench with no strings attached. It supports PostgreSQL, MySQL, MariaDB, SQLite, Oracle, SQL Server, and dozens more relational databases. The SQL editor has syntax highlighting, a data editor with filtering, ER diagrams, and SSH tunneling. The Apache License means commercial use is fine.

The catch is scope: Community is SQL-only. NoSQL databases (MongoDB, Redis, Cassandra), cloud-native warehouses (BigQuery, Redshift, Snowflake), and the Visual Query Builder are locked behind Pro at $199/user/year. Enterprise Edition costs $250/user/year. If your stack is relational, you may never need to upgrade. If you work with a mix of SQL and NoSQL, the free tier runs out fast.

Best for: Teams on a relational stack that need a multi-database GUI without a recurring bill.

Beekeeper Studio Community

Beekeeper Studio's Community Edition is a genuinely capable free SQL client for MySQL, PostgreSQL, SQLite, SQL Server, and more. It installs with no account required, and the Community Edition has no expiry. Core features include a tabbed query editor, table structure editing, and import/export.

The paid tier ($9/user/month, or a one-time Indie License) adds cloud workspaces that sync connections and saved queries across machines, an AI Shell for natural-language queries, and a richer JSON row viewer. If you work on one machine and do not need AI features, the Community Edition covers most use cases. If you regularly switch between laptops, the lack of sync is a real gap.

Best for: Individual developers who want a modern, clean interface without paying for features they do not need.

HeidiSQL

HeidiSQL is fully free and open source, with no paid tier and no feature gates. It supports MariaDB, MySQL, SQL Server, PostgreSQL, SQLite, and Interbase/Firebird. Features include a data editor, bulk export (CSV, HTML, XML, SQL, LaTeX, PHP Array), SSH tunneling, SSL, user privilege management, and direct server-to-server exports.

Until May 2025, HeidiSQL was Windows-only. The project now has a native Linux build (via Lazarus/FreePascal), but macOS support is still absent. The UI is utilitarian: no ER diagrams, no visual query builder. It is maintained by a small team and updated regularly.

Best for: Windows users working with MySQL, MariaDB, or SQL Server who want zero cost and zero friction.

pgAdmin

pgAdmin is the official open-source GUI for PostgreSQL. It is free, always, with no paid edition. It runs as a desktop app on Windows, macOS, and Linux, or as a web application you can self-host. Features include a full SQL editor with autocomplete and graphical EXPLAIN plans, a schema browser, server monitoring, and built-in backup/restore using PostgreSQL utilities.

The tradeoff is that pgAdmin works only with PostgreSQL. It will not connect to MySQL, SQL Server, or any other engine. The web UI is also heavier than most native apps: it loads slowly on older hardware and the interface can feel cluttered for simple tasks. But if PostgreSQL is your primary or only database, pgAdmin is the standard choice and costs nothing.

Best for: PostgreSQL developers and DBAs who want the most complete, officially supported free tool.

TablePlus

TablePlus is a polished native app for macOS, Windows, and Linux that supports PostgreSQL, MySQL, SQLite, SQL Server, Redis, and more. The free tier has a specific set of limits: 2 open tabs, 2 open windows, and 2 advanced filters at a time. There is no time limit and no account required. The free version is genuinely usable for simple queries and browsing.

For most development workflows, those limits become friction quickly. Once you need to compare two queries side by side, or work with more than two filter conditions, you hit the ceiling. A paid license costs $79 per seat (one-time, perpetual), which includes one year of updates. After that year, the build you have works forever, and renewal is $49/year to stay current. That structure is reasonable, but the free tier is better described as an extended trial than a standalone free product.

Best for: Users who want to evaluate a premium-feeling GUI before committing to a one-time purchase.

Supabase (Free Hosted Postgres)

Supabase is in a different category from the desktop clients above. It is a hosted platform that gives you a full Postgres database, authentication, storage, and edge functions. The free plan includes 500 MB of database storage, 2 active projects, 50,000 monthly active users for auth, 5 GB database egress, and 500,000 edge function invocations per month.

The critical limit: free projects are paused after 7 consecutive days of inactivity. You can unpause from the dashboard and your data is intact, but any scheduled job or external service pointing at the database will fail during the pause window. There are also no automated backups and no SLA on the free tier. The Pro plan starts at $25/month and removes the pause behavior, adds point-in-time recovery, and increases all resource limits.

Best for: Side projects and prototypes that need hosted Postgres plus built-in auth and storage, and can tolerate the inactivity-pause behavior.

Who should pick what

You need to connect to multiple databases (Postgres, MySQL, SQLite, SQL Server) from one tool: Start with DBeaver Community. If you later need NoSQL or BigQuery, upgrade to Pro.

You are on Windows and primarily use MySQL or MariaDB: HeidiSQL is the fastest path to a free, full-featured client.

You work exclusively with PostgreSQL: pgAdmin is the natural choice, with the deepest feature set and no cost.

You want a modern, aesthetically clean app on any OS: Beekeeper Studio Community or TablePlus free tier. Beekeeper gives you more open tabs; TablePlus gives you a more polished native feel at the cost of the tab and filter limits.

You need a hosted database for a side project: Supabase free tier is the strongest option in this category, as long as you can tolerate the inactivity pause.

FAQ

Is DBeaver Community really free for commercial use?

Yes. DBeaver Community is released under the Apache License 2.0, which permits commercial use without restriction. There is no expiry, no seat limit, and no feature that unlocks after payment. The Pro and Enterprise editions add NoSQL support, cloud warehouse connectors, a Visual Query Builder, and AI integrations, but the Community edition is not a trial of those features. It is a separate, stable product that has been maintained for over a decade.

What happens to my Supabase project if it is paused?

After 7 consecutive days without any database activity, Supabase pauses free-tier projects. The project stops accepting connections, so any app or cron job pointing at it will fail. Your data is preserved. You can manually restore the project from the Supabase dashboard at no cost. Upgrading to Pro ($25/month) removes the pause behavior entirely.

Does the TablePlus free tier expire?

No. The TablePlus free tier has no time limit and does not require an account or credit card. The limits (2 open tabs, 2 open windows, 2 advanced filters) are permanent constraints, not a countdown. You can use the free version indefinitely. The one-time paid license costs $79 per seat and includes one year of updates; after that, the build you have continues to work without renewal.

Can HeidiSQL connect to PostgreSQL?

Yes. HeidiSQL added PostgreSQL support alongside its long-standing MySQL and MariaDB support. It also connects to SQL Server, SQLite, and Interbase/Firebird. The tool was historically Windows-only, but a native Linux build was released in May 2025. macOS is not yet supported.

How does Beekeeper Studio Community differ from Beekeeper Studio paid?

The Community Edition is open source and free permanently. It covers core SQL editing, table management, and import/export for MySQL, PostgreSQL, SQLite, SQL Server, and others. The paid tier ($9/user/month) adds cloud workspaces that sync your saved connections and queries across devices, an AI Shell for natural-language query generation, and an enhanced JSON row viewer. If you work on a single machine and do not need AI features, the Community Edition is fully functional.
