SPOTLIGHTInventList
InventList is the public home for indie builders. Log every ship (releases, features, bug fixes), build Series with live embeds of your actual work, keep a journey dashboard, and share your story in one permanent place. Includes a CLI for shipping from the terminal, roadmaps, collections, and a weekly "What Shipped This Week" digest. Free forever, built for operators-of-one who ship in public.
A control plane for self-hosted Rails operations. One place to run, monitor, and maintain apps across mixed infrastructure - Kamal and Docker or native Caddy and Puma. Fleet dashboard, SSH execution, deploys, backups, alerts, and recurring jobs over servers you already own.
Operating procedures you can call, instead of documents you hope someone reads. Recipes as data, per-subject runbooks, stable names for rituals, and per-run evidence — so did-last-nights-run-complete is a query, not a guess. Ruby 3.2+, Rails 7.1+, PostgreSQL.
