Reactive Resume v5 is a free, open-source, privacy-first resume builder emphasizing self-hosting and data ownership with no tracking or monetization. The project has accumulated 39.4k GitHub stars but shows minimal current launch velocity (2 HN points, no recent discourse), suggesting it is an established tool rather than a nascent breakout.

One insight: The absence of monetization signals (no pricing, no revenue claims, no paid tier) and flat recent velocity indicate this is a stable OSS commodity tool, not a wedge opportunity—any replication would compete on free-tier features alone, eliminating margin and unit economics.
