Start with the guided setup

Follow the setup below in your own workspace. For a demonstration of the prompt-copying process, open the optional walkthrough.

Watch the setup walkthrough
Step 1 · setup
Three minutes, four steps, nothing to install by hand

Claude sets it up for you. You just paste.

Never used Claude? It is free and takes 30 seconds to open. Copy the instruction below, paste it into Claude, and it reads this page and walks you through everything, one question at a time.

  1. Tell Claude how to talk to you

    One tap. It changes how much Claude explains, and how slowly it goes. You can change it any time.

  2. Copy your setup instruction

    A short instruction plus a link to this page lands on your clipboard. First copy asks for your email once. That unlocks every button across the whole library.

  3. Open Claude in a new tab

    Free account, no card, 30 seconds. This tab stays open so you can come back.

    Open claude.ai
  4. Paste, send, and answer one question

    Claude reads this page, asks which computer you are on, then guides you step by step until it works. If anything errors, tell Claude what you see, and it fixes it with you.

Install Open Source CRM to Replace Salesforce on my computer. Walk me through it.

Repo: https://github.com/twentyhq/twenty
What it does: A self-hosted, AI-native CRM that replaces Salesforce: objects, pipelines, workflows, and Claude agents built in, plus 10 migration fixes that cut your $165 to $350 per seat monthly bill.

I am comfortable copy-pasting and following instructions, but I am not a developer.

Rules:
- Plain English. Define jargon the first time it appears (repo, env var, port, dependency).
- One step at a time. Exact command in a code block. Tell me which app to paste it into (Terminal on Mac, PowerShell on Windows).
- One sentence per command explaining what it does and what success looks like.
- After each command, wait. I will tell you the output before you move on.
- If a tool is missing (git, node, docker, python), give me the one-line install for my OS first.
- If something errors, diagnose before the next step. Do not skip.

First message: ask only "What is your operating system, macOS, Windows, or Linux?" Then start step 1.

Reference steps from the public guide (adapt to my OS, do not just paste them at me):
1. Stand up the open CRM on a $40/month server with one Docker command. Your records and pipeline live in your own Postgres and never leave it.
2. Run the schema-map prompt to mirror every Salesforce object, field, and pipeline stage, then export Salesforce via Data Loader, dedupe, and import.
3. Wire Claude to the CRM via MCP, then stand up deal scoring, the weekly forecast, and contact enrichment as agents on top.
4. Run both systems in parallel for two weeks, reconcile nightly until counts match three days running, then cut over and cancel the seat.

Stop when the app opens and I confirm it works.
Step 2 · run it on your data

Step 1 set it up. These 10 prompts do the work.

The 10 prompts

Grab the whole pack as one file, or tap any prompt below to copy it on its own. Placeholders that look like {{THIS}} get swapped for your own numbers — and if you ran Step 1, Claude fills them in for you.

One .md file · all 10 prompts, numbered, in order · nothing left out.
Click to copy
<role>
You are a RevOps board: a Salesforce admin of 8 years, a CRM migration lead, a data engineer, and a sales ops analyst. You plan the move together and surface risk early.
</role>

<task>
Before any migration work, set up the move. Ask the four questions below, present lettered options, and WAIT for the user to answer.
</task>

<questions>
1. What are you running today? (A) Salesforce Sales Cloud (B) Sales + Service Cloud (C) Salesforce + Outreach/Gong (D) Salesforce + ZoomInfo/Apollo
2. Migration stage? (A) Scoping the move (B) Mid-migration, parallel run (C) Final cutover prep (D) Post-cutover cleanup
3. Where does your data live for this work?
   (A) Upload Salesforce exports (CSV) into this Project's knowledge
   (B) Paste schema and sample records into the prompt
   (C) Connect the open CRM via MCP so Claude reads it live
   (D) Pull from a governed data warehouse
   (E) A mix
4. Context tokens I still need: {{SEAT_COUNT}}, {{OBJECTS_USED}}, {{CUSTOM_FIELDS}}, {{INTEGRATIONS}}, {{CUTOVER_DATE}}
</questions>

Confirm the four answers in one block. State the output bar: zero data loss, every record reconciled, every custom object mapped, no cutover until counts match.

Built on open source
Twenty (open-source CRM, AGPL-3.0)

The code is public and free. The setup instruction above installs and wires it for you. You never need to open this link.

You don't own a CRM. You rent one — every month, forever.

At $165 to $350 per user a month, you're not buying software — you're paying rent on your own customer data, and the bill only goes up. Own the database instead and that six-figure annual seat charge drops to the price of a server.

Path A · free

Run the build independently

The setup rail and every prompt above are free and stay free. The cost is your time, and the risk of wiring it wrong on live data.

Back to the prompts
Path B · done with you

Connect it to your operation

We migrate and dedupe every Salesforce record, rebuild your custom objects, wire the Claude agents, and run both systems in parallel for two weeks — reversible, so nothing is lost. Then we hand it over and you own it.

data safety

Before you use live numbers

  • • Run last quarter's numbers first. Live data is not a test bed.
  • • Nothing here uploads to us. It runs in your own Claude account, on your own machine.
  • • A named human reviews and signs every output before it reaches a board, lender, or client.
  • • Wiring the open-source piece to real systems? Keep keys out of public code and add access control first — or have us do that part.
