CRM and sales decision
Zoho CRM
A competent developer can build a useful CRM subset (contacts, pipeline, email) and self-host it, but replicating Zoho's scale, integrations, polished feature set, and global infrastructure is impractical for DIY.

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
- Manage contacts, track deals through a pipeline, log activities/interactions, and send basic templated emails.
What it still won’t have
- Global data-center footprint and the vendor-managed infrastructure
- Hundreds of integrated first- and third-party apps from Zoho's suite
- Enterprise SLA, professional support, and bundled compliance posture
- Mature, polished product features (reports, analytics, advanced automations, Zia agents)
What remains hard
- Infrastructure at scale
So much so that we prefer to own the entire technology stack, including running our data centers globally.

Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 1 seat.

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted CRM using Node.js (Express), Postgres, Redis (for background jobs), and React. Include: REST API for contacts/accounts/deals/activities; Postgres schema and migrations; React app with contact list, contact detail, deal pipeline board, activity timeline; auth (email+password, admin role); SMTP/IMAP integration for sending/receiving templated emails; background worker for reminders/automations; CSV import/export; Docker Compose files for local deployment and a simple production-ready Dockerfile and systemd unit. Out of scope: multi-tenant billing, advanced analytics, AI agents, and global multi-region deployment. Require input validation, error handling, tests for API endpoints, and README with deployment steps.
How we checked
How the score was reached

- 3/3 assessment runs agreed+4
- Hard moats found in the evidence-3
- Evidence score61
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.
