description	Install SendyKit alongside your existing Sendy deployment

Installation model

SendyKit installs next to Sendy. It does not patch Sendy core files.

That means:

• your licensed Sendy install stays where it is
• SendyKit reads the same database
• SendyKit adds its own sendykit_* tables
• if SendyKit stops, Sendy still works

Before you install

You should have:

• a working Sendy install
• shell access to the server
• Sendy database credentials
• a SendyKit license key for self-hosted installs

Install command

curl -sSL https://install.sendykit.dev | bash

The installer should:

• detect OS and architecture
• download the correct binary
• prompt for license details
• create initial config

First boot sequence

sendykit migrate
sendykit serve

What migrations do

SendyKit migrations are versioned and non-destructive.

They create SendyKit-owned tables such as:

• sendykit_migrations
• sendykit_feature_flags
• sendykit_webhooks
• sendykit_analytics_events
• sendykit_doctor_reports
• sendykit_audit_log

They do not modify Sendy core tables.

Verify the install

sendykit health
sendykit doctor
sendykit brands list

If those work, you have the main operator surfaces connected.
