We ranked these by real free-tier limits — user caps, feature gating, and whether reports/invoicing are actually included — rather than marketing claims, verified against each provider’s current pricing page as of August 2026. “No feature caps” in the title means we prioritized tools that don’t quietly wall off reports or exports on the free tier, not tools with literally zero restrictions of any kind.
Quick Comparison
| Tool | Free Plan Cap | Reports Included? | Self-Hosted Option? |
|---|---|---|---|
| Clockify | Unlimited users/projects | Yes, basic reports | No |
| Toggl Track | 5 users, unlimited projects | Basic only (no custom reports) | No |
| Kimai | Unlimited (self-hosted) | Yes, plus invoicing | Yes, fully open-source |
| Harvest | 1 user, 2 projects | Yes | No |
| TimeCamp | Unlimited users, only 1 project | Yes, basic | No |
1. Clockify — Best Overall Free Plan
Unlimited users, projects, and basic reports make Clockify’s free plan the most usable at scale without paying anything. The gap is billable rates and timesheet locking, both paid-only — fine for personal tracking, less so for client billing needing an audit trail. See our full Toggl vs Clockify vs Harvest comparison for the deeper breakdown.
- Pros: unlimited users and projects, basic reports included free
- Cons: no billable rates or timesheet locking without upgrading
2. Toggl Track — Best Timer Experience
Toggl’s 5-user free plan trades some of Clockify’s headcount generosity for the smoothest, fastest timer of any tool on this list — a real factor in whether you actually track every billable minute rather than forgetting half of them.
- Pros: fastest, most frictionless timer
- Cons: capped at 5 users, no custom reports free
3. Kimai — Best Self-Hosted, Privacy-First Option
Kimai is fully open-source, genuinely unlimited when self-hosted, and bundles customer/project management, invoicing, and permissions — more business-oriented feature depth than any purely free cloud tool on this list. The tradeoff is setup: you’ll need basic server hosting (similar to self-hosting n8n, covered in our workflow automation guide) rather than simply signing up.
- Pros: genuinely unlimited and free, includes invoicing and permissions
- Cons: requires self-hosting setup, less polished interface than commercial options
4. Harvest — Best If You Need Invoicing on a Very Small Scale
Harvest’s free plan is the most restrictive here (1 seat, 2 projects), but it’s the only cloud option on this list with genuine native invoicing included free at that small scale — useful if you’re a true solo freelancer with only a couple of active clients.
- Pros: native invoicing even on the free tier
- Cons: only 1 user and 2 projects, tightest cap of any tool listed
5. TimeCamp — Best for Unlimited Users on a Single Project
TimeCamp’s free plan supports unlimited users with basic reporting, but caps you at just 1 project — a real constraint for anyone juggling multiple clients. Its $2.99/user/month Starter plan removes that cap and is one of the cheapest paid upgrades on this list.
- Pros: unlimited free users, cheapest paid upgrade of the group ($2.99/user/mo)
- Cons: free plan limited to just 1 project
How We Chose These Picks
We prioritized tools where the free plan is genuinely usable for real client work, not just a demo, and specifically called out where reports, billable rates, or invoicing are quietly paywalled despite an otherwise generous-looking free tier.
Once you’ve picked a tracker, our billable hours tracking guide covers the habits that matter more than the tool itself, and our time-to-invoice guide covers connecting tracked time to actual client invoices.
FAQ
Is there a genuinely unlimited free time tracker?
Kimai, when self-hosted — it’s open-source with no user or feature caps at all. Among cloud tools with no server required, Clockify’s free plan is the most generous.
Which free time tracker includes invoicing?
Harvest, on its very limited free tier (1 seat, 2 projects), and Kimai, if you’re willing to self-host.
Do free time trackers show ads?
No — none of the tools on this list display ads on their free tiers. Limits come through feature gating (reports, billable rates, invoicing), not intrusive advertising.
