Flanner: The Control Point for AI-Generated Planning Docs

Research context and background

Flanner is a free, open-source tool designed to help developers manage the planning documents created by AI agents. It acts as a central hub that keeps these documents organized, versioned, and connected to real work tasks. Without tools like Flanner, AI-generated markdown files often scatter across repositories and issue trackers, making them hard to find and track. Flanner solves this by serving as a single control point for all planning documentation.

Benefits

Flanner offers several key advantages for developers and teams:

• Automatic Organization: Flanner acts as a guard hook that automatically routes every plan through the system. It uses files like CLAUDE.md and AGENTS.md to ensure AI agents save their documentation without needing manual reminders.
• Seamless AI Integration: It works smoothly with popular AI assistants like Claude Code and Codex through the Model Context Protocol. This allows AI tools to manage planning documents directly.
• Clean Repository Management: The tool automatically manages gitignore rules to prevent plan files from being committed to Git. This keeps the main code repository clean while maintaining local version control.
• Complete Version History: Every plan file includes metadata that tracks project info, versioning, and ownership. Changes are tracked using semantic versioning, so users can see the full history of all plan iterations.
• Local and Private: All data is stored in a local SQLite database on the user's machine. This means no account or cloud dependency is required, keeping data private and offline-ready.
• Flexible Interfaces: Users can choose between a beautiful web dashboard for viewing and editing plans or a powerful command-line interface for project management and syncing.

Use Cases

Flanner adapts to various development workflows and team sizes:

• Solo Developers: Individual developers can use Flanner to organize architecture decisions and planning with AI assistance. It helps keep their technical notes structured and easy to find.
• Development Teams: Teams can share plan files, track who owns each change, and maintain consistent documentation across the group. The web dashboard makes it easy for multiple people to view and edit plans.
• AI-First Workflows: Teams that rely heavily on AI agents can use Flanner to manage planning documents while maintaining clear audit trails of what the AI created and when.
• Project Documentation: Developers can store RFCs, technical specs, and architecture decisions with automatic versioning. This ensures important decisions are never lost.
• Open Source Projects: Project maintainers can manage roadmaps and feature planning using git-ignored local files. This keeps the public repository clean while maintaining detailed internal plans.
• Remote Teams: Distributed teams can facilitate asynchronous collaboration through the web dashboard and clear ownership tracking. Team members can review plans at their own pace without needing real-time meetings.

Pricing

Flanner is currently free and open-source. Users can install it via pip with a simple command. The tool is MIT licensed, which means it is free to use, modify, and distribute. While the local tool is free, Flanner Cloud is on the roadmap. This future offering will include shared storage for team collaboration and enhanced features. Users can join the waitlist to receive notifications when the cloud service launches.

Vibes

The tool has received positive attention from the developer community for solving a real pain point in AI-assisted development. Users appreciate that it keeps their repositories clean while still providing robust version control for planning documents. The ability to automatically link plans to issue trackers like Linear and Jira has been highlighted as a major benefit for teams that need to connect documentation to actual work progress. The open-source nature of the project has also generated interest, as developers value tools that do not require cloud accounts for basic functionality. The upcoming cloud features have generated excitement among teams looking for shared collaboration capabilities.

Additional Information

Flanner is built with a focus on privacy and simplicity. All data resides locally on the user's machine, which is a significant advantage for teams concerned about data security. The project is actively developing integrations with other platforms. While Linear and Jira integrations are currently available, integrations with GitHub Issues, Notion, and other platforms are in development. The project roadmap includes Flanner Cloud, which will add shared storage and enhanced team collaboration features. Users can join the waitlist to be notified when these new features become available. The tool is available via pip installation, making it easy to add to existing development environments.
