Show HN: Closed Rings – A CLI-first time tracker for developers

https://closedrings.sh/en
2•samacs•1h ago
Hi, HN. I built Closed Rings. A developer-friendly, AI-agent-first time tracker that integrates with my workflow. I wanted something that lives in my terminal and my coding agent.

You can run `rings start "OAuth 2.0" -m "Start integrating OAuth 2.0"` when you start a new task and `rings close` when you're done with your current work. In between, it tracks context switches. You get a stand-up-ready summary, a focus report (longest focus block, number of context switches, time per project), and an export grouped by project or day.

You can also ask your AI agent: _Start tracking "OAuth 2.0"._ Or track retroactively: _Track a 1-hour meeting I forgot to track this morning at 8._ The MCP has a comprehensive set of tools.

This is primarily for consultants or freelance developers who want to start tracking their time right away. The CLI is pretty straightforward, and the MCP allows you to do everything you can do in the dashboard.

Want to integrate it in your own systems? Just create an API key and start communicating with the API.

The stack is pretty simple: Ruby on Rails (MCP + API), Go (CLI).

The pricing is also pretty flat: $7/mo ($60/year).

My first product. Feedback welcome.
