Solo maker post. Tracesleuth is a browser game for learning AWS. It went live on Monday; 7 stages are free with no sign-up: https://play.tracesleuth.com (desktop browser only). What it does. Each stage is a realistic AWS scenario: a bakery moving its storefront into a VPC, a data lake whose queries cost too much, a policy that denies the wrong person. You build or change the setup, press Send, and a simulator follows the packet (or the query, the request, the alarm) hop by hop. When it fails it stops at the exact hop, says why, and gives the concept and the exam tip. Numbers. 198 hand-built stages, 6 domains, 18 stage types, mapped to 10 AWS exam guides (the Solutions Architect Associate path is 53 stages). About 15 to 40 minutes a stage. What it is not. Not a question bank, not a course, and there is no LLM in the game: a deterministic simulator applies rules written from the AWS docs, and every stage links the pages it draws on. Independent, not affiliated with AWS. I used AI coding tools while building it; the stages and the rules were written and checked by hand. Pricing. 7 stages free, then one-time, no subscription: $10 to $30 per exam path or $25 per domain, USD before tax through Paddle. 14-day refund if you have cleared under 20 % of what you bought. Built with. React, three.js and TypeScript; Cloudflare Pages, Workers and D1 behind it; Astro for the site. How it plays, on any device: https://tracesleuth.com/how-it-plays/ What I would like from you. Play stage 1 (an instance with a public IP that the internet still cannot reach) and tell me where it lost you, whether "watch it fail" teaches anything a diagram does not, and what you would want before paying for a path.   submitted by   /u/vivekpadia70 [link]   [comments]
