Payroll tools carry a lot of operational risk: teams need payroll logic, HR workflows, licensing clarity, and evidence that the project is still being maintained. For May 2026, ToolVitals compares the supplied open/source-visible Payroll Tools data using health, shipping, openness, licensing, GitHub stars, and the overall ToolVitals score.
This ranking includes only open/source-visible tools from the supplied data. The order is based first on ToolVitals score, with GitHub stars used only as a secondary popularity signal for ties; openness_label and license_label are reported as given so OSI-approved OSS is not mixed up with other source-visible models.
Rankings
| Rank | Tool | Openness | License | Health | Shipping | GitHub Stars | Score | Status |
|---|---|---|---|---|---|---|---|---|
| 1 | Frappe HRMS | OSI-approved OSS | GPL-3.0 | 90 | 97 | 7996 | 93 | 🟢 Excellent |
| 2 | PayrollEngine | OSI-approved OSS | MIT | 66 | 51 | 104 | 68 | 🟢 Good |
| 3 | Hafta | OSI-approved OSS | MIT | 30 | 0 | 143 | 33 | 🔴 Needs Attention |
Top 3 Highlights
Frappe HRMS ranks first with a 93 ToolVitals score, backed by a 90 health score and a 97 shipping score.
PayrollEngine ranks second with a 68 ToolVitals score and is listed as OSI-approved OSS under MIT. Its description points to a regulation-driven payroll framework with multi-tenant, multi-country, API-first, and low-code/no-code features, but its 66 health score and 51 shipping score place it well behind Frappe HRMS in this snapshot.
Hafta ranks third with a 33 ToolVitals score and a Needs Attention status. It is listed as OSI-approved OSS under MIT and has 143 GitHub stars, but the supplied data shows a 30 health score and a 0 shipping score, so it looks much less active than the other payroll tools in this ranking.
