Perch isn’t available to download yet. It is being prepared for its first public release: free, with no account, for Macs with Apple silicon.
When Perch is released, this page will have the download, its version, size and SHA-256 checksum, and how to install and check it.
Until then, the manual shows what Perch does, and Pricing what will stay free.
One companion from the Chrome Web Store serves both.
A companion from Firefox Add-ons, for Firefox 140 or later.
Included in Perch; you turn it on in Safari’s settings.
