Harvey: the repo and the setup guide
Harvey finds businesses worth selling to, reads their websites, writes cold email that mentions something specific about each one, sends it, reads the replies and works the conversation toward a meeting. It runs on your computer, in a loop.
It runs on your Claude subscription through Claude Code, so there is no model API bill. It is open source, free, and MIT licensed.
Open Harvey On GitHubgithub.com/ethanplusai/harvey Open The Setup GuidePDF . opens in a new tabThe setup guide is going up shortly. The repo and the steps below work now.
The guide is 20 pages: install, keys, settings, your first prospect list, the approval outbox and the rules that keep your domain out of spam.
What you need first
02
Python 3.11 or newer
Check with python3 --version. A Mac ships 3.9: install a newer one first.
03
A mailbox on a second domain
Gmail or Google Workspace, on a domain you bought for sending, not your main one. Warm it up before real volume.
04
Finding businesses
Free on its default source. No Apollo, ZoomInfo or Clay account needed.
05
Every email waits for you
By default nothing sends until you approve it in the dashboard at localhost:5555.
// set it up
Three steps to a running Harvey
On a computer, in the Terminal app. Tap Copy, paste, press Enter.
Step 1 of 3 . start here
The easy way: let Claude set it up
Paste this into your terminal. It downloads Harvey and opens Claude Code inside it.
git clone https://github.com/ethanplusai/harvey.git cd harvey claude
Step 2 of 3
Then say this to Claude
The repo ships with instructions that turn Claude Code into a setup wizard. It checks what is missing, installs it, asks what it needs and learns your product.
set up Harvey for me
Step 3 of 3
Or do it yourself
The same steps by hand, from the repo's quick start. Swap the address for your own website.
python3.13 -m venv .venv && source .venv/bin/activate && pip install -e . cp .env.example .env harvey train https://your-company.com harvey signals --confirm free harvey discover harvey dashboard harvey run

"claude: command not found"
Claude Code is not installed yet. Install it from claude.com/claude-code, run claude login, then try again.
It says my Python is too old
Harvey needs Python 3.11 or newer. On a Mac: brew install python@3.13, then use python3.13 in the commands.
Will it send emails without asking me?
Not by default. Every email waits for your approval in the dashboard. Full autopilot is a setting you have to turn on.
Can I send from my main email?
Do not. Cold email from your main domain can land it in spam for good. Buy a second domain, set up SPF, DKIM and DMARC, and warm it up for 2 to 4 weeks first.
You are the sender: follow CAN-SPAM, include a working opt-out and your mailing address.
Does it work on a phone?
No. It runs on a Mac, Windows or Linux computer.
None of these fixed it
Check the Troubleshooting section of the repo's README, or email support@variancemarketing.com.
