Getting Started

Download Keisen for your platform and install it. The app starts with a 7-day free trial — no account or credit card needed.

System requirements

  • macOS 12+ (Apple Silicon)
  • Windows 10+ (x64)
  • Linux (AppImage, x64)

Installation

  • macOS — open the .dmg file and drag Keisen to your Applications folder. If macOS shows an "unidentified developer" warning, right-click the app and select Open.
  • Windows — run the .msi installer and follow the prompts. If SmartScreen blocks it, click "More info" then "Run anyway".
  • Linux — download the .AppImage, make it executable (chmod +x Keisen.AppImage), and run it.

Creating your first project

  1. Launch Keisen. You'll see the project selector in the top-left corner.
  2. Click New connection and select your database engine (SQLite, PostgreSQL, MySQL, or Redis).
  3. Fill in the connection details — or paste a connection URL directly.
  4. Choose a color to identify this project at a glance.
  5. Click Connect. Keisen will connect and load the schema automatically.

Running your first query

  1. Type a SQL query in the editor — e.g. SELECT * FROM users LIMIT 10.
  2. Press ⌘ Enter (macOS) or Ctrl+Enter (Windows/Linux) to execute.
  3. Results appear in the grid below the editor with column types, row counts, and execution time.

What's included in the trial

The 7-day trial gives you full Pro-tier access: all database engines, AI assistant (2,500 queries), charts, EXPLAIN plans, schema diagrams, inline editing, export, SSH tunneling, and everything else. No feature is locked during the trial.
