01 / Projects

Start the whole project. Not twelve tabs.

A project is everything it takes to run your app: the web server, the queue worker, the asset watcher, your terminals and your agents. Add a repo, press Start, and it all comes up in your login shell, the way it would in your own terminal.

✓ Give each command its own working directory and environment ✓ Auto-restart crashed commands, with backoff and crash-loop detection ✓ Restart a command when files matching your globs change ✓ Stop, start or restart one command or the whole project ✓ One table for every command, agent and terminal, with its git branch

Claude Code · Build the project overview

Run agents in parallel. Step in only when one needs you.

Give Claude Code one task and Codex another, each in its own session inside the project. HackUtilities reads Claude's own session state to tell working from waiting, so you hear about a permission prompt the second it appears, not ten minutes later.

Working
Input required
Permission required
Done
✓ OS notifications and a dock badge when an agent is waiting ✓ Live session titles: see "Add cursor pagination", not "Claude Code 2" ✓ Drop or paste files and screenshots straight into the prompt ✓ Your installed CLI, your login, your subscription. Nothing proxied.
03 / Terminals

Real terminals, attached to the project they belong to.

Every session is a real PTY running your own shell with your own PATH, so asdf, nvm and mise just work. Switch between sessions and the scrollback is still there.

Unlimited scrollback
50,000 lines by default, or no limit at all.
Clickable links
Cmd or Ctrl+click URLs and OSC 8 hyperlinks.
Clean copy
Agent gutter indentation is stripped, so commit messages paste clean.
Replay on attach
Output keeps buffering while you look at something else.

Skills · Installed

Every skill on your machine, in one grid.

Skills for Claude Code and Codex live in a handful of hidden folders and two different config formats. The skills manager puts them side by side, lints them, and lets you switch each one on or off per agent without hand-editing settings.json or config.toml.

✓ Install from GitHub, a folder, an archive, or a bundled catalog of 586 skills ✓ Lint with quick fixes for the typos that silently break a skill ✓ Edits keep the rest of the file byte-for-byte; deletes go to the trash

06 / A working day

Everything except your editor, in one place

  1. 09:00
    Start the project
    One click brings up the web app, the API and the queue worker.
  2. 09:04
    Hand out the work
    Claude Code takes the dashboard. Codex takes the pagination bug.
  3. 10:12
    Answer a prompt
    A notification says Claude wants to run a migration. Click, approve, back to your editor.
  4. 10:40
    Debug a token
    Copy a JWT from the terminal output and HackUtilities offers to open it in the JWT Debugger.
  5. 11:15
    Test a webhook
    Fire a sample payload at your app, or catch its outgoing calls in the local webhook server.
  6. 11:30
    Ship it
    Codex is done. Copy its commit message without the gutter indentation, and push.
07 / Local by design

Your code, your keys, your machine

01
Real binaries
HackUtilities launches the agent CLI you installed. Same login, same config, same release cadence as in your terminal.
02
Nothing proxied
Agents talk to their providers directly. We never see a prompt, a file or a token. No account, no telemetry.
03
Tools offline
Paste production secrets without a second thought. Only tools that exist to go online, like DNS lookup, touch the network.
04
Hands off your files
Removing a project never touches its folder. Config files are edited in place with a backup, and deletes go to the trash.

FAQ

Does HackUtilities replace my terminal or IDE?

It replaces the pile of terminal tabs, not your editor. Keep writing code in VS Code, Cursor or whatever you like. HackUtilities runs the dev servers, agent sessions and shells around it, and each project can open straight into VS Code.

Which AI coding agents does it support?

Claude Code, Codex, Gemini CLI and OpenCode are built in, and any other command-line agent can be added as a custom tool. HackUtilities launches the CLI you already installed, with your own login and your own subscription.

Does HackUtilities see my prompts or my code?

No. Agents talk directly to their own providers, exactly as they do in any terminal. HackUtilities has no proxy, no account system and no telemetry. The 46 tools run on your machine and most never touch the network at all.

Can I bring my projects over from Solo?

Yes. If a project folder already has a solo.yml from Solo, HackUtilities imports its processes as commands, so you don't have to set them up again. Imported commands only run after you trust them on your machine, and any later change asks again.

Do I need a subscription?

Not for HackUtilities. It is a one-time purchase with lifetime updates. You bring your own agent subscriptions, such as Claude or ChatGPT, if you want to run agents.

Which platforms are supported?

macOS (universal, Apple Silicon and Intel) and Windows 10 and later.

Stop switching windows.
You already pay for your AI subscription. HackUtilities doesn't add another: one payment, lifetime updates. Start with the 14-day trial, no card and no account.
