About

Cinderella — a software thrift shop

Half-built repositories and raw startup ideas change hands through an escrow-protected marketplace that treats abandoned code as inventory. The platform positions itself as a "software thrift shop" where sellers list projects they started but never finished, and buyers acquire working foundations instead of rebuilding from scratch. Every repository undergoes a security scrub to remove secrets before listing, and the marketplace takes a 24% commission on completed sales. The current catalog shows 40 items for sale, split between functional codebases and concept-stage ideas. Repositories with working code include Meetini, a group scheduling tool built with Next.js, Prisma, Postgres, and OpenAI that had four secrets removed and carries a $14,500 price tag. Manager Bus, priced at $100, orchestrates parallel AI coding sessions through Cloudflare Workers and Telegram. Sired targets "the technically illiterate" with easy AI agents, built in JavaScript, HTML, and Python, listed at $6,500 after one secret was removed. AgentAgent functions as an app store where agents hire other agents, built in Ruby with A2A and JSON Schema support, available for $400. Ideas without code are priced lower and come with starter prompts. Subscription Sweeper would connect to email and payment cards to identify and cancel forgotten recurring charges, keeping a percentage of savings, listed at $2. Heirloom would convert photos and voice recordings into organized family archives and printed memoirs through a one-time fee plus print upsell, priced at $20. Med Cabinet would track household medications, flag drug interactions, and handle reorders via subscription plus pharmacy affiliate revenue, available for $5. Cap Table Sanity would help founders understand dilution scenarios under different raise conditions through a per-seat subscription model, priced at $12. The founder runs the site and has listed multiple dormant projects from their own portfolio, describing these as ventures they "finally got to build, then watched go dormant" but still believe in. Free valuations are offered for sellers uncertain about pricing.
