Each product has a *-showcase repository under this org that contains either the full production source (or, where the product carries substantial curated IP, an architecture-only build with the content layer removed). All seven are published under the PolyForm Noncommercial License 1.0.0 — a source-available license that explicitly allows reading, cloning, running locally, and noncommercial study, while forbidding commercial reuse of the code in a competing or paid product.
Each showcase repo ships with a SHOWCASE.md that documents exactly what was kept, what was removed, and why.
- One person ships the whole stack — design, code, deploy, monitor, support
- No third-party tracking SDKs on customer-facing surfaces — first-party analytics only (Plausible / custom SQLite)
- GDPR-compliant from launch — every product with PII implements the standard
data_request+redactflows - Strict license hygiene — code is source-available under PolyForm Noncommercial; the products themselves are commercial
