What solo-founder products launched today
Three same-day solo launches each picking a different wedge — a Postgres primitive, a Markdown superset, and an interval-math calculator — all shipping as single-repo artifacts with no signup.
For your next solo ship, model it on PgQue — a single primitive with one concrete before/after number (constant time, not "fast"), one repo URL, and the author in the comments — and skip the dashboard, landing page, and signup entirely.
"One repo + author in comments" works for HN launch day but every one of these products evaporates when the author stops replying within the hour; expect the 30-day retention curve to be brutal.
