What solo-founder products launched today
Three Show HN launches today share a shape — single-artifact tools that refuse to upload, refuse to route through a vendor, or refuse to accept scope creep. @rileyt's Daemons continues at 65 points; @sanity's Mediator.ai lands at 157 points with a Nash-bargaining approach to fairness; @dchu17's Ctx at 71 points ships a /resume primitive that works across Claude Code and Codex. On Product Hunt, InstantDB leads the indie-builder slice at 290 votes with "complete backend with auth and storage in one prompt."
Ship a Ctx-shaped primitive this weekend — one plain-text config file that every agent reads — for the niche you already use daily (e.g. agent memory for research notes, for AWS ops, for legal drafting); the migration-wave distribution is still open for two more weeks.
"One config file across all agents" is exactly the kind of standard every vendor will quietly break as soon as one of the config files becomes popular — Anthropic adds a proprietary block, Cursor adds a binary side-channel, and the portable config fragments within a quarter.
