Collins
🗂️

Every session, organized

A sidebar of all your agent sessions, grouped by project — searchable, auto-titled, starred and renamed as you like, with guide lines saying which are working and which are waiting on you — and a click resumes any of them in a real VTE terminal tab, in the directory it last worked in, inside your own shell.

📋

Copy & paste that just works

Plain Ctrl+C copies whenever text is selected (and interrupts otherwise); Ctrl+V pastes; right-click for a menu. No Ctrl+Shift gymnastics.

✍️

Drafts that wait for you

A real prompt box — multi-line, spell-checked, open the moment you start typing, pasted images and all — that never loses a prompt. Close the tab or quit mid-sentence and the draft is back when you return, for a running session or one you haven't started yet.

🔀

Pull requests, start to merge

Every PR a session opens is tracked on its row and tab — CI, conflicts, unanswered comments — with the actions to match — read its description and threads as GitHub renders them, merge, ask for a review, or send the failure back to the agent as a prompt.

🧰

An IDE around the agent

A native git page — the session's diff beside its terminal, with the commits of the whole stack, staging by file, hunk or line, and notes the agent can read and leave — plus a code editor with the agent's latest edits one click away, shell panels under every tab, a gallery of everything the session has shown you, and the composer floating over the terminal or docked below it.

🔔

Stays out of your way

Close the window and sessions keep running behind a status icon that counts what's waiting for you — reopen one and Collins re-attaches to the live process instead of resuming a copy. Sessions raise notifications when they need you — a card inside the window, or a desktop notification when you're away — a bell in the header keeps the history, and Caffeine Mode keeps the machine awake while agents work.

An opinionated, Claude-first workspace ​

Call it an Agent-First IDE, an AI-Native Workspace, or an Agent Orchestrator — Collins is an opinionated take on what a desktop workspace built around a coding agent should look like: the agent front and center, with your sessions organized around it. It is native — GTK4, libadwaita, and VTE, not a webview — and it is also, deliberately, a tool for Claude: there are no plans to support other agents. And to be upfront about it: Collins is itself entirely vibecoded — the code is written by Claude Code. GPL-3.0, open source.

Why "Collins"? ​

My wife keeps referring to Claude as Collins by mistake. So now when she asks me if I'm talking to Collins, I can say yes.

Collins is a fork of agent-session-manager by Máté Molnár — see the original project's website. All credit for the original app goes there; this fork is GPL-3.0 like the original.

The PPA and the COPR are the channels that update themselves — the PPA on Ubuntu 24.04 and 26.04 LTS and their derivatives (Mint, Pop!_OS, elementary, Zorin), the COPR on every current Fedora and on RHEL 10 and its rebuilds; the .deb covers Debian and the rest of its family, with an .rpm on the same releases page for an RPM distro that would rather not enable a repository; and PyPI is the way in everywhere else — it works anywhere the system GTK libraries are installed (--system-site-packages is required — Collins gets GTK from your distro, not from PyPI). See Getting Started for system requirements and the details of each channel. The installed command is collins.

Unofficial community tool — not affiliated with or endorsed by Anthropic. Released under GPL-3.0. Forked from agent-session-manager by Máté Molnár.
