Show HN: Momentum – showcase what you're shipping (opens in new tab)

Momentum is a way to showcase what you're shipping. Things are moving faster than ever with Claude Code and Codex, and it can be hard to keep up or even share your own progress effectively. At the end of the day, the code is the progress and what runs in production, so a friend and I built this as a fun weekend project to explore the space.

Momentum grabs your PRs (backfilled up to 90 days), generates summaries of each one, calculates relevant statistics, and summarizes the narrative arcs of what's been shipped recently. We also use the project website to grab a logo, colors, and writing style (this can updated in the settings). You can edit PR summaries and narrative arcs as well as add customer quotes. As new PRs get merged to main, it uses a webhook to keep things up to date, creating new summaries and trends.

Here's a few I created from open source projects that I forked:

* https://app.heytangent.com/momentum/pandas

* https://app.heytangent.com/momentum/shadcn-ui

* https://app.heytangent.com/momentum/kibana

Note that when you sign up, it requests access to your repos so it can access the PRs. It uses each PR to create a summary and only provides a link to the PR if the repo is set to public. Otherwise, only the summary is shown. In the Settings page, you can delete everything and then revoke the Oauth token in GitHub should you choose to.

Let me know if you have feedback or questions!
