CRM and sales decision
HubSpot Sales Hub
A small team can build a usable CRM and basic sales automation, but HubSpot's large integration catalogue, enterprise analytics, AI agents, and brand/scale advantages make a full replacement impractical for most teams.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Capture leads into a contact database, track contact activity, manage a sales pipeline, send/outreach emails, and automate basic workflows.
What it still won’t have
- 2,000+ pre-built integrations from HubSpot Marketplace
- HubSpot-hosted enterprise analytics, attribution and multi-touch reporting
- Built-in Agent Hub AI agents and managed AI features
- HubSpot onboarding, migrations, and premium support services
What remains hard
- Integration maintenance
Works with the tools you already use. 2,000+ integrations.
- Brand trust
299,000+ customers in over 135 countries grow their businesses with HubSpot.

Runnable build prompt
Build a minimal self-hosted Sales CRM using a Postgres backend, a Node.js (Express) API, and a React UI. Include: (1) lead capture endpoint + web form that writes to Postgres, (2) contacts and deals schema and REST CRUD, (3) a kanban-style pipeline UI for deals, (4) email templates + send via SendGrid with open/click event logging, (5) a rule-based workflow runner to trigger emails or create tasks, and (6) activity logging and basic reporting (counts by stage). Out of scope: multi-channel ad management, AI agents, app marketplace integrations, enterprise attribution. Provide error handling, input validation, unit tests for API routes, and a Docker Compose setup for local dev and a short README for deployment to a single-cloud VM.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
