Fizzy: the editor that arrived with an ecosystem

A new open-source task editor from the folks behind Basecamp blew up on GitHub — and it already talks to AI agents out of the box.

A new tool arrived with friends already waiting

Something unusual happened on GitHub this week. A small, well-made task management tool called Fizzy — built by the team behind Basecamp and Hey — appeared and hit #1 trending within a single day. Over a thousand developers starred it before most people had even heard the name.

That kind of momentum usually takes months. This took hours.

What makes it worth paying attention to isn't the speed, though. It's what showed up alongside it. Within days, independent developers had already built connections between Fizzy and the AI tools that businesses are starting to use: Claude (the AI assistant), n8n (a tool that links your apps together), and MCP servers — a new standard that lets AI agents read and update your tools without you lifting a finger.

So if you use Fizzy to manage your tasks, an AI agent could theoretically check what's on your plate, move cards, update priorities, and hand things off — while you're in a meeting or asleep.

This doesn't happen often. Most tools take years to grow an ecosystem. Fizzy seems to have arrived already dressed for the job.

The tool is free and open-source, which means anyone can use it, inspect it, and adapt it. No subscription required to get started.

Words worth knowing

Open-source — software whose code is publicly available. Anyone can use it, improve it, or build on top of it. Usually free.

Ecosystem — the collection of other tools, plugins, and integrations that grow around a piece of software. A thriving ecosystem is a sign of trust.

MCP (Model Context Protocol) — a new standard that lets AI assistants like Claude connect directly to your apps and take actions inside them. Think of it as a universal plug for AI.

Plugin — a small add-on that extends what a tool can do, without changing the tool itself. Like installing an app on your phone.

If you're already experimenting with AI in your business, Fizzy is worth a quiet look. Not because it's shiny — because it arrived ready to work with the things you're probably already building toward.
