Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

2.4

GPA, above 8 of the 42 other time tracking apps we grade

Kimai is an open-source, browser-based time tracker for project work. Time is recorded against customers, projects and activities, then analyzed in reports, exported, or turned into invoices from configurable templates. It can be installed on your own server at no cost under the AGPL 3 license, or used as Kimai Cloud, a paid service hosted in Germany and operated by the same developer.

To get you started, here are 9 things to know about Kimai, taken from its own pages and our grades.

Hosting it yourself needs SSH access to a server.
From our grade for ease of use
  1. 1

    Best for open-source time tracking with invoices

    It runs in the browser only, and any phone or desktop app is made by somebody else.

  2. 2

    Paid plans start at about $3.35 a month for each person

    As its pricing page puts it: €2.99 per user / month, billed annually (€3.99 billed monthly).

  3. 3

    There is a free plan

    Self-hosted Kimai is free and open source (AGPL 3) with unlimited users, customers and projects. Extras such as expenses, custom fields and kiosk mode are paid plugins. The Kimai Cloud pricing page lists no free plan.

  4. 4

    It runs on Web

    Web.

  5. 5

    Project time tracking

    Time is recorded against customers, projects and activities, with budgets and order numbers on projects. Every installation supports unlimited users with roles.

  6. 6

    Invoicing

    Invoices are created from timesheets with configurable templates and invoice numbers, grouping options for entries, and output formats such as PDF and DOCX.

  7. 7

    Reports and exports

    Recorded time is analyzed by user, customer, project, activity, tag and period. Timesheets export as XLSX, PDF, CSV or HTML, and exported records can be locked.

  8. 8

    A 2.4 GPA, above 8 of 42

    That is against the other time tracking apps we grade, on value, the free plan, features, ease of use and platforms.

  9. 9

    The plain part of Kimai you could make: time tracking, invoicing and reports. What surrounds it you could not. The 3 things listed below take a company, not a weekend.

The report card

Best for open-source time tracking with invoices

Kimai is open-source time tracking with invoicing: host it yourself for nothing, or pay from €2.99 a user for the cloud version run by the same developer in Germany. It runs in the browser only, and any phone or desktop app is made by somebody else. Self-hosting needs a server and SSH, extras like expenses are paid plugins, nothing tracks by itself, and the cloud has no free plan after its 30-day trial.

ToolGPA report cardKimaiGraded Oct 10, 2026
SubjectGradeComment
Value for moneyBCloud Standard is €2.99 a user a month billed annually, or €3.99 monthly, and invoicing, exports and the API are already in it. That puts it in the cheaper quarter of the category. Professional is €3.99. Prices are in euros and exclude taxes.
Free plan and trialBFree only if you host it. The open-source edition costs nothing on your own server, with unlimited users, customers and projects, and one person can stay on it. Extras like expenses are paid plugins, and Kimai Cloud has no free plan, just a 30-day trial.
FeaturesCTime goes against customers, projects and activities, with budgets, reports, exports and invoices from your own templates, plus teams, roles and SAML login. But nothing tracks by itself, and on the self-hosted edition expenses, custom fields and kiosk mode are plugins you buy, expenses at €99.
Ease of useCNo store rating on record. On the cloud it's a web app you sign in to, but it's one where you build the thing: customers, projects, activities and invoice templates before any of it reports. Hosting it yourself needs SSH access to a server.
Platforms and integrationsCA browser, and that's it from Kimai itself. There's a JSON API and a short list of links, GrandTotal, Bexio and VS Code, but every phone and desktop app on its integrations page is made by somebody else, and some of them cost money.
Grade point averageFair, out of 4.02.4

An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Who Kimai is for

  • Fits if you want your time tracking data on a server you control
  • Works for freelancers and agencies who invoice clients straight from timesheets

Who it is not for

  • Skip it if you want an official phone or desktop app, because Kimai itself only runs in the browser
  • Not for you if you want a free hosted plan, as the cloud gives a 30-day trial and nothing after
  • Tight if you self-host and need expenses, custom fields or kiosk mode, since they're paid plugins, expenses at €99
  • Watch out: cloud prices are in euros before tax, and on Professional kiosk mode and SAML show only with annual billing
  • Too light for automatic tracking, since nothing records by itself

Good to know

Good for

  • Teams that want to host their own time tracking data
  • Freelancers and agencies invoicing clients from timesheets
  • Organizations that need EU hosting and open-source code

Worth knowing

  • Cloud prices are in euros and exclude taxes; the pricing page lists no free cloud plan, only a 30-day trial.
  • On Cloud Professional, kiosk mode, SAML single sign-on, a custom domain and IP access restriction are shown only with annual billing.
  • Kimai runs in the browser; the mobile and desktop apps on its integrations page are made by third parties, and some are paid.
  • Self-hosting needs SSH access to a server, and plugins such as expenses (99 €) are bought separately.

From our grade for platforms and integrations
Project time tracking

Invoicing
Invoices are created from timesheets with configurable templates and invoice numbers, grouping options for entries, and output formats such as PDF and DOCX.

Kimai's GPA of 2.4 is higher than 8 of the 42 other time tracking apps we grade, and level with 10.

It stands best on free plan and trial (B, above 29 of 42) and worst on features (C, above 0).

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

Keep it

The plain part of Kimai you could make: time tracking, invoicing and reports. What surrounds it you could not. The 3 things listed below take a company, not a weekend.

That makes this kind of software worth paying for, not this one in particular: 24 of the 42 other time tracking apps grade higher. It costs $40.21 a year. Kimai is open source, so there is a third way: take its code and run it yourself.

What you could make

  • Time tracking, invoicing and reports: an app builder makes these well.

What you could not

  • It is priced for each person, which means accounts and billing for a team.
  • It plugs into other products, GrandTotal, Bexio and VS Code among them, and has an API.
  • What a company asks for before it lets staff use something: single sign-on and roles and permissions.

What this rests on. Kimai’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
