• README.md

Fizzy is a Kanban tracking tool designed for managing issues and ideas, developed and maintained by 37signals. The application provides a visual board-based approach to task and idea management, enabling teams to organize, prioritize, and track work items through various stages of completion. As a product from the creators of Ruby on Rails and Basecamp, Fizzy embodies the philosophy of building focused, opinionated software that solves specific problems effectively (README.md:1-3).

The project is released as open-source software under the O'Saasy License, allowing organizations to run their own instances either through pre-built Docker images or by deploying customized versions using Kamal. This flexibility makes Fizzy suitable for teams that require data sovereignty, customization capabilities, or prefer self-hosted solutions over cloud-based alternatives (README.md:27-29).

Technology Stack

Based on the project's deployment options and development practices, the following technology stack has been identified:

Note: The specific programming language, web framework, and database technologies are not explicitly stated in the available source files. The deployment documentation (docs/docker-deployment.md, docs/kamal-deployment.md) and development guide (docs/development.md) referenced in the README would contain this information—需要确认: access to these documentation files is required to provide complete technology stack details.

Core Features

Fizzy provides the following core capabilities as a Kanban tracking tool:

1. Visual Kanban Board: A board-based interface for visualizing and managing work items across different stages
2. Issue Tracking: Comprehensive tracking of issues from creation to resolution
3. Idea Management: Dedicated functionality for capturing, organizing, and developing ideas
4. Self-Hosted Deployment: Full control over data and infrastructure through self-hosted options
5. Docker-Based Installation: Quick deployment using pre-built container images
6. Customizable Codebase: Ability to modify and extend the application using Kamal deployment
7. Development Environment: Local development setup for contributors and customizers
8. Style Guide Integration: Standardized code contribution guidelines

Deployment Architecture

Fizzy supports two primary deployment models, each designed for different use cases and organizational requirements.

Docker-Based Deployment

The Docker deployment option provides a streamlined installation process using pre-built container images. This approach is recommended for organizations that want to run Fizzy without modifying the source code. The deployment requires access to a Docker-capable server and configuration of customization options (README.md:8-11).

Key Characteristics:

• Pre-built images eliminate build complexity
• Server requires Docker runtime
• Configuration through environment variables or config files
• Suitable for standard use cases

Kamal Deployment

For organizations requiring code customization, Kamal deployment offers greater flexibility. This method allows modification of Fizzy's codebase and deployment of those changes to target servers. Kamal is 37signals' deployment tool, suggesting integration with their ecosystem (README.md:11-13).

Key Characteristics:

• Full code customization capability
• Custom deployment pipeline
• Integration with Kamal deployment tooling
• Suitable for organizations with specific requirements

Architecture Diagram Explanation:

• User/Organization: Represents the team or entity seeking to deploy Fizzy for their issue and idea tracking needs
• Deployment Decision: The critical branching point determining which deployment path to follow based on customization requirements
• Docker Path: The streamlined deployment flow using pre-built images, requiring minimal setup but offering no code modification capabilities
• Kamal Path: The flexible deployment flow enabling full code customization, suitable for organizations with specific workflow requirements

Evidence Points:

• README.md:6-13 — Outlines the two deployment strategies and their respective use cases
• README.md:8-11 — Details Docker deployment requirements and process

Development and Contribution Workflow

Fizzy welcomes community contributions and code modifications, supported by a structured development and contribution process.

Local Development Setup

Developers intending to modify Fizzy must set up a local development environment. The project provides a dedicated development guide that covers environment configuration, dependency installation, and development workflows (README.md:16-19).

Development Setup Requirements:

• Local environment configuration (detailed in docs/development.md)
• Dependency management
• Development server setup
• Testing infrastructure

Contribution Process

The project maintains specific code quality standards through a style guide. Contributors must review and adhere to the style guide before submitting code changes (README.md:22-25).

Contribution Requirements:

• Review STYLE.md before submitting code
• Follow established coding conventions
• Maintain consistency with existing codebase

Development Workflow Diagram Explanation:

• Setup Phase: Initial repository cloning and environment configuration guided by the development documentation
• Development Phase: Core code modification workflow including branch creation, implementation, and local testing
• Review Phase: Quality assurance step ensuring all contributions meet the project's style standards
• Submission Phase: Final commit and contribution submission after passing all checks

Evidence Points:

• README.md:16-19 — Encourages code modification and references development guide
• README.md:22-25 — Defines contribution requirements and style guide reference

Project Directory Structure
