Rippling
Do not build — Rippling's value derives from unified proprietary workforce data, broad regulated services (payroll/PEO/compliance), and scale/enterprise integrations that are costly to replicate; a small team can implement a narrow HRIS but not the full paid product.

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 employee records, automate onboarding/offboarding workflows, run simple reports, and enforce role-based permissions across apps.
What it still won’t have
- Proprietary unified workforce data and context across HR/IT/Finance
- Enterprise-grade compliance and tax filing services
- Global payroll, Employer-of-Record, and other regulated services
- Deep, production integrations and turnkey onboarding for many downstream systems
- Vendor SLA, support, and managed services (engineers building custom apps)
What remains hard
- Proprietary data
Rippling has your workforce’s full context—roles, locations, reporting lines, and more—even as things change.
- Compliance and regulation
Maintain compliance in all 50 states
- Switching costs
Every product is built on a unified platform. The more apps you use, the more powerful Rippling AI becomes.
- Brand trust
Trusted by 30,000+ customers
First-year cost
No published price
Rippling does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted HRIS and onboarding automation using: Next.js for frontend, Node.js + Express for API, Postgres for data, Redis for job queue, and Docker for deployment. Implement: (1) employee directory CRUD with audit logs, (2) onboarding/offboarding workflow engine with configurable checklists and email/webhook triggers, (3) role-based permissions and an approvals flow, (4) a reporting API and simple dashboard for headcount/hire/termination metrics, and (5) connectors for SMTP and one external integration (Slack or SSO). Out of scope: payroll tax filing, global payroll/PEO, benefits administration, and managed compliance services. Include comprehensive error handling, unit and integration tests, Docker Compose and a production deployment guide, and basic observability (logging + health checks).

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.
