Standout Differences
Free plan scope varies widely
OpenTimeClock's Free Plan supports unlimited employees, DeskTime's free tier is capped at one user, and TMetric's free tier caps out at two seats, making the free plans suited to very different team sizes.
DeskTime, OpenTimeClock, TMetric
Automatic productivity scoring
DeskTime classifies tracked apps and URLs into productive, unproductive, or neutral categories automatically, a capability neither OpenTimeClock nor TMetric offers out of the box.
DeskTime
Flat-fee pricing for large teams
OpenTimeClock's Paid Plan is a flat $39 per month for unlimited users rather than per-seat pricing, which can be far cheaper than DeskTime or TMetric once a team grows past a handful of people.
OpenTimeClock
Billing-grade budgets and invoicing
TMetric turns tracked hours into client invoices and lets teams set project budgets with alerts, plus a timer embedded inside more than fifty other web apps.
TMetric
GPS and biometric attendance verification
OpenTimeClock supports GPS geofencing and facial recognition clock-in, verification methods that DeskTime and TMetric do not document.

Pros & Cons
DeskTime
Pros
Fully automatic tracking removes the need for employees to manually start and stop timers.
Built-in productivity scoring works out of the box with minimal configuration.
Free plan available for single users, making it accessible for freelancers.
Combines time tracking, scheduling, and invoicing in a single product.
Cons
Screenshot capture and scheduling tools are gated behind the higher Premium tier.
Employee monitoring features like screenshots can raise privacy concerns among tracked staff.
Free tier is limited to a single user, so teams must move to a paid plan almost immediately.
Enterprise pricing is not publicly listed and requires contacting sales.
OpenTimeClock
Pros

Paid plan is inexpensive relative to per-user competitors, especially for larger teams.

Cons
Free plan loses PDF/Excel report export after the initial 30-day trial period.
Company does not publicly disclose a physical headquarters or leadership team, which may concern due-diligence-conscious buyers.
Interface and design feel dated compared to newer, VC-backed time-tracking competitors.
Smaller integration ecosystem with payroll and HR platforms than larger competitors like TSheets/QuickBooks Time or Deputy.

Frequently Asked Questions
Which tool has the best free plan for a large headcount?
OpenTimeClock, since its Free Plan supports unlimited employees and departments, unlike DeskTime's single-user free tier or TMetric's two-seat cap.
Does DeskTime support GPS or facial recognition clock-in?
No. DeskTime focuses on automatic app and URL tracking with productivity scoring rather than location or biometric verification, which are OpenTimeClock's strengths.
Which tool is best for freelance client billing?
TMetric, since it converts tracked hours into invoices and supports project budgets with alerts.
How does cost compare for a team of twenty employees?
OpenTimeClock's flat $39-per-month Paid Plan covers unlimited users, which can be cheaper than DeskTime or TMetric's per-seat pricing once a team reaches around ten to twenty people.
Which tool includes a built-in focus timer?
DeskTime includes a Pomodoro-style focus timer; this is not mentioned as a feature of OpenTimeClock or TMetric.
Does OpenTimeClock disclose its company headquarters?
No, OpenTimeClock does not publicly disclose a physical headquarters, though it states it has operated since 1997 and hosts data on AWS; DeskTime and TMetric both publish their headquarters locations.
