Meet Sill. A compact browser for people who build, research and get things done. Make room with Sill Glide. Give every project a home with Sill Workspaces — two defining features, built to work together.
Windows x64 portable beta · v1 is still in development
Sill Glide
Reveal your browser frame from the top, left or right. Pin it while you navigate, or let it retreat after a pause. Your page stays in place beneath the overlay.

Sill Workspaces
Give each project a named tab set, with up to 100 workspaces. Switching checks the tabs you leave: verified safe pages sleep and reload when reopened. Forms, editors, selected files, active media, uploads and uncertain pages stay awake. The manager shows sleeping and protected counts.
Protection keeps unfinished work in memory while Sill is open. Restarting restores tab addresses, not unsaved drafts. Memory savings depend on the pages you use.
