For builders who share
Ship the work. Post the proof.
You crossed 1,000 downloads and the announcement is a screenshot of a dashboard. Your progress deserves better than that. Type the number into a card, and the milestone looks like the moment it is, in the same look as everything else you post.

The six posts every builder repeats.
Numbers, growth, kind words, code, launch day and the vote, each in its own template.
This week in numbers
Visitors, downloads, what shipped. The weekly update that takes two minutes.
The growth curve
MRR climbing month by month, headline number and change badge computed for you.
The kind words
A user said something nice. Frame it as the post it deserves to be.
The snippet
The fix, the trick, the one-liner. Syntax highlighted, ready for the thread.
The launch checklist
Launch day, live. The progress bar is the post.
The roadmap vote
Let your audience pick what you build next. Engagement that steers the product.
Or say it in one sentence.
Every example on this page was generated through the built-in MCP server, locally, from one sentence:
"Make a milestone card for 2,000 downloads, sunset template."

What should I post when I build in public?
The work you already did this week: a milestone, your numbers, what shipped, a lesson, a kind review. Each of those maps to a card, so the design question never blocks the posting habit.
Can my agent make these cards for me?
Yes, and this is where it clicks: Monocards bundles a local MCP server, so Claude Code, Cursor or any MCP client can render your milestone or chart from one sentence, on your Mac, with no API key and no tokens.
How do I keep my posts looking consistent?
Save your look once as a template: colors, font, background, logo. Every card you or your agent makes after that comes out on-brand, which is what makes a feed recognizable over time.
How long does a card actually take?
Under a minute once your template exists. Type the value, pick the size, export. The point is to make sharing cheaper than skipping it.
