Can Darwinbox be vibe coded?
Enterprise HR platform covering hiring, onboarding, attendance, leave, payroll and performance for the whole org.
This is not a tool you use alone, it is the system of record for every employee your company has. The parts that look buildable, a leave tracker and an org chart, are the cheap 10 percent. The expensive 90 percent is statutory payroll across multiple countries, tax filings, audit trails, role-based access that HR and legal will actually sign off on, and the fact that finance, IT and the auditors all already read from it. A personal replacement makes no sense because there is no personal version of a company's payroll compliance. If you are a founder with eight people, a spreadsheet plus your accountant beats both this and a DIY build.

The achievable core
- A self-hosted employee directory with leave balances, approval requests and a CSV export you hand to whoever actually runs payroll.
- Run internal workflows such as time-off requests, onboarding checklists, and review cycles.
- A responsive interface with real empty, loading, success, and error states.
The parts a prompt cannot buy
- Statutory payroll, tax and provident fund compliance across jurisdictions, which is the entire product
- Audit trails and access controls that survive an actual audit or an employment dispute
- Integrations with finance systems, background check vendors, job boards and identity providers
- Mobile apps that non-technical employees will use for attendance and expense claims
- Compliance, licensing, and legal accountability are core features.
- Years of history, configuration, and habits make migration costly.

Recommended
Because HR software is bought to reduce risk, not to save time. A wrong pay run or a missed statutory filing costs more than the annual contract, and nobody in the company wants to personally own that. Add the switching cost: once headcount data, leave history, appraisal cycles and payroll inputs all live in one system that finance and IT are wired into, migration is a project with a budget and a steering committee, not a focused implementation.

Context
Darwinbox — Enterprise HR platform covering hiring, onboarding, attendance, leave, payroll and performance for the whole org.
This is not a tool you use alone, it is the system of record for every employee your company has. The parts that look buildable, a leave tracker and an org chart, are the cheap 10 percent. The expensive 90 percent is statutory payroll across multiple countries, tax filings, audit trails, role-based access that HR and legal will actually sign off on, and the fact that finance, IT and the auditors all already read from it.

If you are a founder with eight people, a spreadsheet plus your accountant beats both this and a DIY build.
This brief describes a focused, single-operator replacement for the part of Darwinbox that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.
What you are building
A self-hosted employee directory with leave balances, approval requests and a CSV export you hand to whoever actually runs payroll.
Run internal workflows such as time-off requests, onboarding checklists, and review cycles.
A responsive interface with real empty, loading, success, and error states.
Requirements
Functional
Node 20 and a machine to run it on.
Someone external doing actual payroll and tax filing.
Non-functional
Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
Security: server-side secrets, validated input, and no credentials in the client bundle.
Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
Portability: the operator can export their data and leave without losing it.
Implementation brief
Build a self-hosted internal HR record app for a small team. Not payroll, not compliance, just records and leave.
Stack, no substitutions:
Next.js 15, App Router, TypeScript, Tailwind.
SQLite via better-sqlite3, file at ./data/hr.db, schema created on first run.
No auth provider, no cloud, no telemetry. Single shared password from HR_PASSWORD in .env, checked in middleware, plus an ADMIN_EMAILS list in .env that unlocks admin views.
In scope:
1. Employees table: name, work email, job title, department, manager (self-referencing), start date, employment type, location, status (active, on leave, exited), notes. Full CRUD for admins, read-only directory for everyone.
2. Org chart rendered from the manager field as nested lists, no graph library.
3. Leave: policies table (name, days per year, carry-over cap), balances computed per employee per calendar year, requests with start date, end date, half-day flag, reason, status (pending, approved, rejected).
4. Approval flow: a request goes to the employee's manager, manager sees a queue, approve or reject with a comment. Every state change writes an append-only audit row with actor, timestamp and old/new values.
5. Working-day math that skips weekends and a holidays table admins can edit. Store all dates as ISO strings, no timezone conversion.
6. Reports: leave taken per employee per year, headcount by department, and a CSV export of employees plus approved leave for whoever actually runs payroll.
7. Seed script with 12 fake employees, 2 policies and a few requests so the app is not empty on first load.
Out of scope, do not build: salary fields, payslips, tax logic, expenses, recruitment, performance reviews, mobile apps, email sending, any integration.
Deliverables: working app on npm run dev, npm run seed, a .env.example, and a README that states plainly that this is a record keeper and that payroll and statutory filing are handled by a human accountant outside this system.
Delivery standard
Inspect the repository first, then write a short implementation plan before writing code.
Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
Add structured logs around every external call and return actionable errors without leaking sensitive details.
Write unit tests for the core logic and one automated test of the main user journey.
Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.
Acceptance criteria
A clean install starts the app using only the README and .env.example.
The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
Tests, type checking, linting, and a production build all pass with no ignored failures.
No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.
Non-goals
Do not build these, and do not claim to have replaced them:
Statutory payroll, tax and provident fund compliance across jurisdictions, which is the entire product.
Audit trails and access controls that survive an actual audit or an employment dispute.
Integrations with finance systems, background check vendors, job boards and identity providers.
Mobile apps that non-technical employees will use for attendance and expense claims.
Someone to blame, and to call, when a pay run goes wrong on the 30th.
What you still own after launch
Run migrations, backups, restores, and dependency updates.
Test the critical journey after every model, API, or hosting change.
Monitor failures and fix the edge cases a first prompt will miss.
Maintain every third-party integration as APIs and OAuth rules change.
Risk
High consequence. Use this as a prototype or personal aid. Keep a qualified human and an established provider in the loop for consequential decisions.
Editorial confidence in this assessment: medium. No reviewed project implementation is linked yet.

Before you start
Can Darwinbox be vibe coded?
Not faithfully. This is not a tool you use alone, it is the system of record for every employee your company has. The parts that look buildable, a leave tracker and an org chart, are the cheap 10 percent. The expensive 90 percent is statutory payroll across multiple countries, tax filings, audit trails, role-based access that HR and legal will actually sign off on, and the fact that finance, IT and the auditors all already read from it. A personal replacement makes no sense because there is no personal version of a company's payroll compliance. If you are a founder with eight people, a spreadsheet plus your accountant beats both this and a DIY build.
What can an AI coding agent reproduce from Darwinbox?
A self-hosted employee directory with leave balances, approval requests and a CSV export you hand to whoever actually runs payroll. Run internal workflows such as time-off requests, onboarding checklists, and review cycles. A responsive interface with real empty, loading, success, and error states.
What will a DIY Darwinbox replacement still be missing?
Statutory payroll, tax and provident fund compliance across jurisdictions, which is the entire product; Audit trails and access controls that survive an actual audit or an employment dispute; Integrations with finance systems, background check vendors, job boards and identity providers; Mobile apps that non-technical employees will use for attendance and expense claims; Compliance, licensing, and legal accountability are core features.; Years of history, configuration, and habits make migration costly.
What do I still own after building a Darwinbox alternative?
Run migrations, backups, restores, and dependency updates. Test the critical journey after every model, API, or hosting change. Monitor failures and fix the edge cases a first prompt will miss. Maintain every third-party integration as APIs and OAuth rules change.
