Sidebridge is a native macOS Swift application designed to provide "peripheral vision" for developers working in terminals and with AI agents. It seamlessly integrates crucial project context – such as Git status, diffs, file trees, and agent activity – directly into a floating sidebar that follows your active terminal pane or desktop window, eliminating the need to constantly switch to an IDE. This tool is ideal for developers who prefer a command-line workflow and leverage AI coding assistants like Codex CLI and Claude Code.
Sidebridge addresses the challenge of fragmented project awareness in modern terminal-heavy, multi-agent development environments. It automatically switches context as you move between panes, tabs, and agent chats, ensuring you always have relevant information about the active project, branch, and worktree. Key features include real-time Git status, a "Since Last Focus" summary to quickly catch up on changes, a dedicated agent surface displaying tool calls, goals, and configurations, and a customizable sidebar layout. It also offers a lightweight built-in viewer for quick glances at diffs, READMEs, and various config files.
For enhanced capabilities, Sidebridge offers a Pro version. The free tier provides the active, focus-aware sidebar with today's cross-repo activity and essential Git and agent insights. Upgrading to Pro unlocks durable work history, project-context search across files, commits, and agent notes, deeper project activity beyond today, export options for standups, a writable Agent Brief for structured agent memory, and a Compiler API for agents to query structured project data.
Sidebridge operates on a freemium model. The core active sidebar features are available for free forever, requiring no account or trial. The Pro version, which includes retained history, advanced search, and deeper agent integration, is available as a one-time purchase of $15, upgradeable directly within the app.
The user experience is designed for minimal disruption, with a native macOS interface that can be kept visible, tucked to a tab, or hidden when not in use. It integrates with popular terminal emulators like tmux, Ghostty, iTerm2, Warp, Alacritty, and WezTerm, as well as Codex and Claude Code desktop apps. Sidebridge also offers 30+ themes to match your terminal's palette, ensuring a cohesive visual experience. Documentation is available to guide users on its features and scope.
Built as a native macOS Swift app, Sidebridge ensures high performance and tight integration with the operating system. It reads local repositories, sessions, and retains history on your machine, providing a local-only, structured JSON Compiler API for agents to query project state.
