Hubstaff
Stands out: First-party MCP server and a public REST API at developer.hubstaff.com, with a 14-day trial and no credit card.
Watch out: Starter caps screenshots and app/URL tracking at 500 per seat per month and allows only 5 clients. Grow allows one integration.
Not the right fit for
- Restaurant Fair Workweek shift scheduling
- Companies that refuse activity monitoring and screenshots
OnTheClock
Stands out: One all-in time, PTO, and scheduling plan instead of a feature-gated starter SKU. Active users are anyone on the employee list within 20 days of the bill.
Watch out: Payroll is a separate product with a $250 setup fee, a $40 monthly base, and industry exclusions (non-US workers, cannabis, firearms, gambling, government). Time tracking above 100 employees is enterprise quote.
Not the right fit for
- Global or multi-country workforces. Payroll and many edge cases are US-only
- Enterprises that need UKG-class labor law rules engines
