Why I made it

## The waiting was the problem.

I could stay with a hard programming problem. What kept getting me was the small pause after I handed work to an agent.

A tool call took 20 seconds, so I opened YouTube. The test suite took a minute, so I checked X. The agent finished. I didn't come back.

I wanted one boring guarantee. During work hours, those sites do not open.

Nothing to connect

## Keep your agent setup exactly as it is.

1. 01

  ### Choose the hours

  Set the days and times when those websites should be blocked.
2. 02

  ### Keep coding

  Use Codex, Claude Code, or any other tool. Cactus does not read prompts or watch processes.
3. 03

  ### Keep the sites closed

  The websites stay blocked, and the menu bar shows when access returns.

## Before you download.

### Does Cactus connect to Codex or Claude Code?

No. Keep using whichever agent you prefer. Cactus only needs the websites and hours you choose, and it keeps that configuration on your Mac.

### Will it tell me when an agent finishes?

No. Cactus does not monitor your agent. It only blocks the websites you chose during scheduled hours.

### Can it block desktop apps?

Not yet. Cactus blocks websites today. Desktop app blocking is planned, but it is not in the current version.

## Keep the next wait from becoming an hour.

Cactus is free for seven days. No account or card.
