Best Self-Hosted Time Tracking Tools in 2026

Quick Picks

Use Case	Best Choice	Why
Freelancer/agency billing	Kimai	Full project/client tracking with invoicing and expense management
Developer coding stats	Wakapi	WakaTime-compatible, automatic coding activity tracking
Simple personal tracking	Traggo	Clean UI, tag-based system, minimal setup

Why Self-Host Time Tracking?

Commercial time tracking tools (Toggl, Clockify, Harvest) charge $5-15/user/month. For a 10-person team, that’s $600-1,800/year — for what is essentially a database of start/stop timestamps. Self-hosted alternatives give you the same features with full data ownership, no per-user pricing, and the ability to integrate with your existing invoicing workflow.

The Full Ranking

1. Kimai — Best for Professional Use

Kimai is the most feature-complete self-hosted time tracker. It handles projects, clients, activities, teams, expenses, invoicing, and reporting. Originally a PHP application dating back to 2006, the modern version (Kimai 2) is built on Symfony and provides both a web UI and a REST API. If you’re replacing Harvest or Toggl for a team, Kimai is the closest equivalent.

Pros:

• Full project/client/activity hierarchy
• Built-in invoicing with customizable templates
• Expense tracking alongside time entries
• Team management with permissions and roles
• REST API for integrations
• Plugins for extended functionality (vacation tracking, budgets, approval workflows)
• Active development, strong community

Cons:

• Requires MySQL/MariaDB
• Plugin ecosystem is partly commercial (free plugins + paid plugins)
• UI is functional but not beautiful
• Can feel heavyweight for solo use

Best for: Freelancers, agencies, and teams who need professional time tracking with invoicing.

2. Traggo — Best for Personal Use

Traggo takes a tag-based approach to time tracking — instead of rigid project/client hierarchies, you tag your time entries with whatever labels make sense to you. The UI is clean and modern, setup is minimal (single Go binary, SQLite), and it just works.

Pros:

• Tag-based system — more flexible than project hierarchies
• Single binary, SQLite storage — minimal infrastructure
• Clean, modern web UI
• Dashboard with charts and summaries
• Low resource usage (~20 MB RAM)

Cons:

• No invoicing features
• No team management or permissions
• Smaller community than Kimai
• Limited reporting compared to professional tools

Best for: Individuals who want simple, flexible time tracking without the overhead of a full project management tool.

3. Wakapi — Best for Developers

Wakapi is a self-hosted alternative to WakaTime — it tracks your coding activity automatically via editor plugins. Install the WakaTime plugin in VS Code, JetBrains, or Vim, point it at your Wakapi instance, and it logs time per project, language, editor, and operating system without any manual start/stop.

Pros:

• Automatic tracking via editor plugins (WakaTime-compatible)
• Per-project, per-language, per-editor breakdowns
• Dashboard with coding streaks and goals
• Leaderboard for teams
• WakaTime API compatibility — works with existing integrations

Cons:

• Developer-specific — not a general time tracker
• No manual time entry (it’s all automatic from editors)
• No invoicing or client management
• Requires WakaTime plugin in every editor

Best for: Developers who want automatic coding analytics without sending data to WakaTime’s cloud.

Honorable Mentions

• Solidtime — A newer entrant with a modern UI and REST API. Built with Laravel, designed as a direct Toggl replacement. Worth watching but still maturing.
• Super Productivity — More of a task manager than a time tracker, but has built-in time tracking, Jira/GitHub integration, and break reminders. Electron-based desktop app with optional self-hosted sync.

How to Choose

Replacing Toggl/Harvest for a team? Kimai. It’s the only option with invoicing, team permissions, and professional reporting.

Personal time awareness? Traggo. Tag-based, minimal, and just works.

Developer coding stats? Wakapi. Automatic, zero-effort, WakaTime-compatible.

Frequently Asked Questions

Can Kimai generate invoices from tracked time?

Yes. Kimai has built-in invoicing — select a date range and client, and it generates an invoice from your time entries. Templates are customizable (PDF, DOCX, CSV, HTML). If you need a combined time tracking + invoicing solution, Kimai eliminates the need for a separate tool like Invoice Ninja.

Does Wakapi work with VS Code?

Yes. Wakapi is fully compatible with the WakaTime extension for VS Code. Install the WakaTime extension, set your API key and server URL to your Wakapi instance, and it automatically tracks your coding time per project, language, and file. Works with 50+ editors including JetBrains IDEs, Vim, Emacs, and Sublime Text.

Can I track time on my phone?

Kimai has a mobile-responsive web UI and community mobile apps. Traggo works well in mobile browsers. Wakapi is desktop/editor-only (it tracks coding activity, not general time). For mobile time tracking with a native app, Kimai is the best option among self-hosted tools.

How accurate is automatic time tracking vs manual?

Wakapi tracks actual keystrokes and file activity — it’s extremely accurate for coding time but misses non-coding work (meetings, design, documentation). Manual tools like Kimai and Traggo track whatever you tell them. For billing accuracy, many freelancers use both: Wakapi for coding metrics and Kimai for billable client hours.

Can I export time data for payroll or accounting?

Yes. Kimai exports to CSV, PDF, XLSX, and has a REST API for programmatic access. Traggo has CSV export. Wakapi supports CSV and JSON export. For payroll integration, Kimai’s structured export (client, project, hours, rate) maps directly to most accounting software import formats.

Is there a self-hosted Toggl alternative with a Chrome extension?

Kimai has browser extensions and integrations. For Toggl-style simplicity, the newer Solidtime project is designed as a direct Toggl replacement with a modern UI, though it’s still maturing. Kimai’s REST API also enables third-party browser extension integrations.
