An automated time tracker that stores everything locally, for people who want a detailed record of their computer use without handing it over.

ActivityWatch records what you do on your computer so you can see where the time actually went, and it keeps that record on the machine that produced it. The project's stated goal is collecting as much life data as possible without compromising privacy, which rules out the usual trade of detail for a hosted account.
A local server stores the data and exposes a REST API and a query engine, with a web interface on top. Small programs called watchers feed it: one reports the active application and window title, one reports the active browser tab and its title, and one detects when you are away from the keyboard.
The design answers the complaints the maintainers had with other trackers.
- You own the data: storage stays on your own machine instead of a vendor account.
- Decentralised sync: still in progress, moving data between devices through a folder synced by Dropbox, Syncthing or similar, with no server that sees everything.
- High resolution: raw data is kept rather than long pre-aggregated intervals.
- Extensible: browser extensions and editor plugins already exist, and new watchers can be written against the API.
- Two server implementations: a Python server is the current default and a Rust one is the planned replacement.
Builds are published for Windows, macOS, Linux and Android, and a guide covers building from source. This repository is a bundle of the core components and official modules as submodules, which is also where releases of the whole suite appear.
Time tracking for freelancers and agencies, covering projects, clients, billable rates and multiple organizations under one account.

solidtime is a time tracking application aimed at freelancers and agencies. It handles the chain that follows a tracked hour, which project it belongs to, which client that project serves and what the hour is worth to whoever is billing it.
Work is organized around organizations, and a single account can hold several of them, each with its own members, roles and permissions. Billable rates are set on organizations, organization members, projects and project members, so the number attached to an entry depends on where the rate was defined.
Every piece of a tracked day gets its own management screen.
- Time tracking: an interface built for starting, stopping and correcting entries quickly.
- Projects: created, managed and staffed with project members.
- Tasks: created and assigned to the project they belong to.
- Clients: managed and attached to the projects done for them.
- Import: existing history brought across from Toggl, Clockify or a time entry CSV.
Self-hosting guides live in the documentation alongside a separate repository of worked examples, and a hosted cloud version exists for anyone who would rather not run a server. Contributions follow a vouching process where you open an issue or discussion and agree on an approach before a larger pull request will be considered.
Time tracking application for freelancers and companies, with invoicing, budgets, exports and reporting across multiple users, timezones and languages.

Kimai tracks project time for anyone who bills by the hour, from a lone freelancer to a company with hundreds of users. It replaces the spreadsheet that quietly drifts away from what was actually worked, and turns recorded hours into invoices without a second tool.
The application is built on PHP with Symfony and Doctrine, with an interface on Bootstrap and Tabler, and it is designed to run on hardware you control.
The feature list reaches well past a stopwatch.
- Multiple timers: run several at once, or switch to a punch-in punch-out mode for shift-style work.
- Invoicing and budgets: money and time budgets, with rates set per user, customer or project.
- Reporting and exports: advanced search and filtering, data exports, and a JSON API for whatever the interface does not cover.
- Authentication: SAML, LDAP or database accounts, with two-factor authentication over TOTP.
- Teams and roles: customizable role and team permissions across multiple users, timezones and languages, with over thirty translations already written.
Running Kimai calls for PHP 8.2 or newer, MariaDB 10.6 or MySQL 8.4 at minimum, a web server on its own subdomain rather than a subdirectory, and the gd, intl, json, mbstring, pdo, tokenizer, xml, xsl and zip extensions. Documented installation paths include Docker images, Caddy with Docker Compose on Hetzner or DigitalOcean, plain SSH with Git and Composer, and Synology, with a plugin marketplace and a hosted version for teams that want either.
Local time tracking app for macOS and Windows aimed at freelancers and remote workers who bill hours without paying a subscription.

TimeScribe keeps work hours on the machine that recorded them. There is no account to create, no cloud to upload to and no paid tier, which suits freelancers billing clients, remote workers logging hours and anyone who wants a record of the day without handing it to a vendor.
It is a Laravel application wrapped in NativePHP for the desktop, with a Vue and Tailwind interface and a local SQLite database. Start, pause and stop are one click from the menu bar, and the timer can also be driven from Shortcuts, Alfred, Raycast, AutoHotkey or a script through deep links.
Beyond the stopwatch, the app organizes the working week.
- Day and week views: visualize work patterns and see where the hours actually went.
- App activity: track application usage and categorize real work against distractions.
- Projects: log time against projects with descriptions, hourly rates and billing calculations.
- Absences: plan vacation, sick leave and public holidays alongside tracked time.
- Automatic start and pause: screen time and idle status can drive the timer without manual input.
- Exports: send records to PDF, Excel or CSV for reporting elsewhere.
Installers are published for Windows and for Apple Silicon and Intel Macs, with Homebrew and WinGet packages available and automatic updates built in. The interface ships in eight languages, among them Danish, German, French, Italian, Polish, Portuguese and Chinese, and the app is distributed under GPL-3.0.
