Ever Gauzy

An open-source ERP/CRM/HRM platform with time tracking, invoicing, and payroll built in

Best for: Agencies and consulting firms that want an all-in-one open-source ERP/CRM/HRM system with time tracking and invoicing.
Skip if: You want a lean SaaS starter to build a single-purpose product on - Gauzy is a full business-ops platform, not a minimal boilerplate.

Ever Gauzy is a large, open-source business management platform combining ERP, CRM, HRM, ATS, and project management in one Angular + NestJS monorepo. It covers time tracking with activity monitoring, project budgeting, invoicing, payroll, and sales/proposal management, aimed at agencies, studios, and consulting firms rather than a typical lightweight SaaS starter.

Pros

Very broad feature set: time tracking, invoicing, payroll, CRM, ATS in one system
Large, active community (4.3k GitHub stars)
Angular + NestJS monorepo built with Nx, backed by a company (Ever Co.)
Self-hosted or cloud deployment options

Cons

Community edition is AGPL-3.0, a copyleft license that requires source disclosure for hosted use - not a permissive MIT starter
Large monorepo with a steep learning curve, not a quick-start template
More of a full application than a boilerplate you customize and ship quickly
