One switch.
Every AI coding client.
Lessy Router rewrites the configuration of Claude Code, Codex, Claude Desktop and Cursor to use one local gateway — with one balance and three lines. No provider pickers, no environment variables, no restart dance.
macOS on Apple Silicon. Windows and Intel are planned for a later release.
Flip a switch
Turn on the app you already use. Lessy snapshots the original settings, writes only its own keys, and keeps every other provider intact.
Pick a line
Economy for drafts, Stable for daily coding, Ultra for the hardest work. Switching a line never restarts your client.
Know the bill
A live 30-minute usage chart, one USD balance, and a ledger you can inspect. No exchange-rate games.
What changes on your Mac?
Only the documented config files of the apps you enable. Lessy never touches your projects. Turning an app off restores its original configuration byte-for-byte. Tokens stay in the macOS Keychain; MCP secret values never leave the device.
