solidtime is an open-source time tracking application designed for freelancers and agencies. It provides a full-stack solution with a PHP backend (using a custom Laravel-like framework with strict typing) and a Vue 3 frontend served via Inertia.js. The system supports multi-tenant organizations with role-based permissions (Owner, Admin, Employee, Placeholder), project and task management, client and tag tracking, billable rates, goals, and detailed reporting with export to CSV, PDF, ODS, and XLSX. It also includes importers for Toggl, Clockify, Harvest, and generic CSV formats, as well as a native solidtime format. The architecture is a monolith with a RESTful API (versioned under /api/v1) and web controllers driven by Inertia.js. The backend uses a custom PHP framework that resembles Laravel but employs non-standard syntax (declare strict_types, use traits, fn closures). Key entry points include API controllers for time entries, projects, clients, tags, goals, reports, and import/export; console commands for administrative tasks, telemetry, and database consistency checks; and a Filament admin panel for CRUD operations. The frontend is built with Vue 3, Pinia stores, TanStack Query for caching, and a shared UI component library (packages/ui) that provides reusable primitives like dialogs, selects, calendars, and context menus. Data flows center around time entries, which are created via a timer or manual entry, associated with projects, tasks, clients, and tags, and aggregated for reporting and goal tracking. The system uses PostgreSQL as its primary database, with Redis for caching and queueing. External dependencies include a mail driver (Mailpit in dev), storage drivers (local/S3), and optional services like Gotenberg for PDF rendering and Paddle for subscriptions. The codebase is extensively tested with PHPUnit (unit/feature), Vitest (JS unit), and Playwright (E2E), and includes CI/CD pipelines for building, linting, and testing.
Kimai is a self-hosted, open-source time-tracking application built with PHP 8.3+ and Symfony 6/7. It provides a full-featured web interface and REST API for recording timesheets, managing projects/customers/activities, generating invoices, exporting data (PDF, XLSX, CSV, HTML), and producing reports. The architecture follows a classic Symfony monolith with Doctrine ORM, Twig templating, and Webpack Encore for frontend assets. It supports multi-user, multi-timezone, multi-language, LDAP/SAML authentication, two-factor authentication, and a plugin system via tagged services and compiler passes. The codebase is heavily event-driven, with over 70 domain events and subscribers, and includes a rich set of dashboard widgets, custom form types, and validation constraints. The repository is actively maintained with frequent commits, extensive test coverage (PHPUnit), and continuous integration pipelines.
This is a well-crafted Go CLI application for interacting with the Clockify time-tracking API. It provides a comprehensive set of commands for managing time entries, projects, tasks, clients, tags, workspaces, and users. The architecture follows the GitHub CLI pattern with Cobra commands, Viper configuration, and dependency injection via a Factory interface. The application supports both interactive and non-interactive modes, multiple output formats (table, JSON, CSV, Markdown, Go templates), and name-to-ID resolution for convenience. Key features include a step-pipeline pattern for composable time entry modifications, a generic pagination helper for API list endpoints, and a search package with approximate matching. The codebase is well-tested with extensive unit tests using generated mocks, and the project is actively maintained with a robust CI/CD pipeline (GoReleaser, GitHub Actions, Netlify docs site).
Invoice Ninja is a full-featured open-source invoicing and billing platform designed for small to medium businesses. It handles the complete lifecycle of invoices, quotes, credits, purchase orders, payments, and expenses. The system supports multi-tenant SaaS and self-hosted deployments with per-company database isolation, and integrates with over 20 payment gateways (Stripe, PayPal, Mollie, GoCardless, etc.). It provides client and vendor portals for self-service, along with extensive reporting, CSV export, and e-invoicing capabilities (Peppol, Verifactu, France e-reporting). The application follows a monolithic MVC architecture built on a custom PHP framework (Illuminate) similar to Laravel. It uses an event-driven architecture with domain events and listeners for side effects (email, webhooks, activity logging). Background jobs are queued for async processing. The frontend uses Blade templates, Livewire components, and a separate React app for some admin panels. The API is RESTful with OpenAPI documentation. Key entry points are HTTP controllers under app/Http/Controllers, with request validation classes. Core data flows involve creating entities through factories, persisting via repositories, and triggering events that listeners handle. Payment flows go through abstract payment drivers that encapsulate gateway-specific logic. The system also includes extensive reporting, CSV export, and e-invoicing (Peppol, Verifactu, France e-reporting). External dependencies include a relational database (MySQL/PostgreSQL), Redis for caching and queues, Elasticsearch for search, and various third-party APIs for payment processing, tax calculation (ZipTax), bank integration (Nordigen, Yodlee), email delivery (Mailgun, Postmark, Brevo), and e-invoicing gateways (Storecove, Qvalia).
This repository is a comprehensive curated knowledge base and reference directory focused on time tracking, productivity methodologies, and related tools. The dominant character is a flat collection of over 3000 markdown files under `details/`, each describing a specific software tool, productivity technique, author, or research finding in a structured format (overview, features, pricing, use cases). While primarily a reference resource, the repo also contains a few functional software components, including a Spring Boot + Vaadin reporting app for Toggl (toggl-reporter), a Django monorepo with REST API and Keycloak auth for time tracking (timed), a Home Assistant custom component (ha-toggl-track), and a Lua SDK (Qmonix). These are small reference implementations that demonstrate integration patterns. The repository serves as a one-stop guide for individuals and teams evaluating time tracking solutions, learning productivity methods, or building integrations. It cites numerous statistics and studies, but many entries are stale or incomplete (e.g., research stub pages with placeholder text). The code components are basic and not production-ready without further development.
