Every AI coding session,
organized and
right where you left it.
Give each project its own workspace that opens in the right folder, keep every session alive between days, and get pinged the moment an agent finishes. No more Windows Terminal tabs, cd-ing, and daily re-setup.
Buy once · Use your own agents · Windows + Linux
Close it. Open it tomorrow. Your work is back.
Every agent session resumes right where the conversation left off, even after a 14-hour gap. No re-attaching, no hunting for which agent was doing what. Most terminals lose your agent sessions the moment you close them. Mosaic brings them back.
Already living in Windows Terminal? It runs the agents. Mosaic wraps them in persistent per-project workspaces that open in the right folder, and notifies you the moment a session finishes, with a custom sound and one click to jump to it. You could script bits of that yourself; here it is built in and yours to tune.
Open in the right folder, every time
Each project gets its own workspace and contexts. New sessions open in its folder, so no cd-ing or re-setup each day.
Pinged the moment a session finishes
A Windows notification and your chosen sound, then one click jumps you to the session that needs you.
Kanban, todos, and focus tasks
An integrated board synced with GitHub Issues, right beside the sessions doing the work.
Works with the agents you already use
Auto-detects 10 CLI agents (Claude Code, Codex, Gemini and more), side by side. Your keys stay local.
Customize it to your taste
Backgrounds, drag-and-drop split sidebars, your own layouts, themes, and tab styles.
Aliases, snippets, skills a click away
Command aliases, per-project right-click snippets, and your skills without leaving the terminal.
A real GPU terminal underneath
xterm.js v6 with WebGL, copy mode, inline images, clickable paths, and 100K-line scrollback.
Room to go deeper
A full MCP server, HTTP API, and CLI to script Mosaic, live cross-session activity oversight, and a remote PWA to drive it from your phone.
Pay once. The version you buy keeps working.
Standard is $79 and Pro is $149, both perpetual. Buy once, with an optional yearly renewal for updates, so the version you bought keeps running if you never renew.
