Hourly true-cost comparison of 11 crypto exchanges, with a 2.4M-row dataset
Skontro measures what a crypto trade really costs: fee, spread, network and withdrawal, on 11 exchanges and 25 coins, every hour. What you get: Full codebase: 115k lines of TypeScript (NestJS API, Next.js 16 web, Postgres, Redis), 178 test suites with 2,858 tests Proprietary dataset: 2.4M measured cost rows since June 2026, growing hourly Live product at skontro.com: cost comparison, exchange trust score, monthly research index, MCP server, embeddable widget 325 indexed pages (English and German), 7 domains, brand and social accounts Stripe billing, auth, mail and monitoring fully wired Honest numbers: live since August 2026, pre-revenue, 4 registered users. Google Search Console, last 90 days: 3,660 impressions, 8 clicks. Running cost about $140 per month, can be cut to about $80. Why I sell: I built it solo next to a full-time job and have no time for distribution. The engineering is done; it needs an owner with an audience or a sales channel. Good fit for: a crypto comparison site, a tax or portfolio tool, a data vendor or a publisher that wants its own cost index.
Next step: <p>Put it in front of an existing crypto audience: the comparison pages earn affiliate commission from six exchanges as soon as traffic arrives. License the hourly cost dataset to exchanges, portals and newsrooms. Embed the widget on partner sites. Publish the monthly cost index for press and backlinks. Switch on the built Austria tax module and the Pro plans.</p>
