Your coding agents.Always in sight.
Sidelong is the ambient command center for Claude, Codex, Antigravity and Maestri. See who needs you, return to the exact session and act — without leaving the app you're in.
- Claude Code + Desktop
- Codex
- Antigravity
- Warp
- Maestri
Keep using Warp, Terminal, your editor and Maestri. Sidelong is the quiet layer around them that tells you what changed and takes you back to the right place.
Supervise the work without becoming the dashboard.
Sidelong watches the agents and tools you already use. It surfaces only the next useful fact, then gets you back to the exact place where the work is happening.
One glance replaces a sweep through every terminal.
Live hooks distinguish working, waiting, finished, interrupted and failed sessions. Names, tasks and subagents stay attached to the conversation, and macOS can notify you when a turn ends.
It belongs around your work, never over it.
A dashboard asks you to leave the work. A pinned widget covers it. Sidelong reads the layout the way you do: it finds the region no window occupies, moves there, and moves again when the layout changes. Drag it once and the spot is remembered per display.
Everything you need to run the agent loop.

Every Claude, Codex and Antigravity limit
Five-hour, account-week and model-specific windows, read from the tools already on your Mac. Every limit gets its own line, reset and urgency colour. No second login inside Sidelong.
Turn finishedWarp · Maestri ↗Every session, and exactly where it lives
Working, waiting, finished, interrupted or truly failed — from live hooks, not a timer. Renames stay in sync. Click once for the exact Warp tab or Maestri terminal, and get a notification when a turn ends.

A permission prompt or question becomes a card on the display you are looking at. Apple Intelligence can summarize the plan, explain risk and clarify choices entirely on device before you allow, deny or answer.
Your pull requests, with CIPro
Only your PRs, only what changed: CI, requested reviews and new commits. On supported Macs, Apple Intelligence explains a failing job locally. Merge in two clicks when GitHub says it is clean.
Local ports, with an ownerPro
What is listening, which agent session opened it, and the framework behind it. Open it in the browser, read the live log or stop it. Unknown servers get a useful on-device name.
CPU and memory, in the notch
The same numbers Activity Monitor shows, grouped by app, with the agents' processes labelled. Kill from the panel.
Made for the edges of a Mac.
Bring two bubbles together.
Drop one onto another at an edge and they fuse into a capsule; in a corner, into rings. Each widget's outline is its own gauge. Pull them apart and they are bubbles again.
Flick a bubble across the screen.
Release it while it is moving and it glides to a landing, slowing down the way a scroll does. It lands where you meant, not where you let go.
Dock it to the notch.
Drag a group of two to the camera cutout and it becomes a strip beside it: pure black, because the cutout is. Hover and the strip drops down, CPU and memory on top, each widget's details below.
Everything stays on your Mac.
