MySQL client that runs in your browser

Planche is a free MySQL GUI — a browser-based alternative to MySQL Workbench, phpMyAdmin or paid desktop tools — with nothing to install except a one-line local agent. It works with MySQL 5.7, 8.x and compatible servers such as Amazon RDS, Aurora and PlanetScale.

How it connects

Run npx planche in a terminal (Node 22+). It starts a tiny local agent on your machine that holds the MySQL connection and opens this page already paired to it. The browser talks only to 127.0.0.1; your host, user and password never go to any server. Remote databases can be reached through an SSH tunnel (password, key or ssh-agent, honoring ~/.ssh/config).

No Node.js? One line installs the agent — curl -fsSL https://planche.dev/install.sh | sh on macOS and Linux, irm https://planche.dev/install.ps1 | iex on Windows. Everything stays inside your home directory, nothing asks for an administrator, and a machine without Node.js gets a private copy of it. Afterwards planche is a command that starts instantly; planche upgrade keeps it current.

Because the agent runs locally you can use Planche as a MySQL GUI on macOS, Windows and Linux without installing a desktop application — just a browser and Node.

Also available: SQLite viewer, MariaDB client, PostgreSQL client, SQL Server client, Oracle client, Neon client, Supabase client, Cloudflare D1 client, Cloudflare Durable Objects client, Redis client, Elasticsearch client and OpenSearch client.

Free to use

Planche has a free tier that needs no account and uploads none of your data — connection profiles live only in your browser. A few advanced features need Pro; see pricing.
