Fizzy: A Kanban Board Your Agent can Talk To

I started using Fizzy, Basecamp's "fun, modern take on Kanban." While Fizzy is devoid of AI features, it is a perfect complement to a CLI agent like Claude Code. I manage my personal todos by talking to Claude and it works surprisingly well.

Basecamp offers a hosted version, but they also open-sourced the code. When your agent can read the source code, it can build its own integration.

Over the last year and a half, people have built increasingly complex systems to organize tasks for agents. Todo lists, then markdown files, then purpose-built databases. Each trying to let the agent handle work without you.

Fizzy takes the opposite approach. It's built for people. But because the code is open, your agent can read it, extend it, and work with it directly. You get a delightful Kanban board you interact with conversationally.

"Please create a Fizzy card to check in with my kids' teacher about..."

"Move the Fizzy about my taxes to waiting on."

"Please mark my Fizzy to reconcile the shared water bill with my neighbor complete."

If you haven't used Kanban before: each task lives in a column, and moves across columns as it progresses. Planning, in progress, waiting on, done. Simple enough to glance at, structured enough for an agent to manipulate. The state you see is the state the agent understands.

After each short request (you can just speak them if you prefer), your dutiful agent updates the board.

Why would someone want to run Fizzy themselves? Because when Fizzy runs on your machine, your agent has full access. It can read the database, hit local endpoints, and modify the code. No API keys.

This does require a bit of setup, but the agent can help. I run one instance locally for work. I run a separate instance on my Zo Computer (a personal cloud computer) for personal todos, accessible from anywhere.

Fizzy uses magic links to log in. When running locally, login emails open in your browser via letter opener. On a normal remote server, you'd have to set up an email integration. But Zo gives you email functionality out of the box.

Fizzy does not ship with an agent integration. But just ask the agent to build one. It can read the source, create the endpoints it needs, and give itself access to any feature you see in the UI. Great open source software built for people turns out to be the best kind of software for agents too.
