An atlas of system designs with interactive architecture diagrams: SKIP, 58/100 | Ideas Lab

A curated, interactive reference library for system architecture patterns that engineers consult when designing systems.

The pain

Engineers designing systems spend time searching across multiple sources, blog posts, and papers to understand how others solved similar problems. They lack a single organized place to see working examples with clear trade-offs explained.

The gap

Free resources exist scattered across the web. Paid alternatives like courses teach concepts but don't function as quick reference tools. No product sits in the middle as a searchable, interactive atlas with diagrams you can modify and learn from.

Build angle

Start by scraping and organizing existing public system design case studies into a searchable database with standardized diagram formats. Add interactivity so users can toggle components on and off to understand dependencies. Charge teams or enterprises for private diagram storage and collaboration features.

Strengths

Real problem for mid-level and senior engineers who design systems regularly.
Low initial build complexity, can start with static diagrams and add interactivity incrementally.
Potential to build a community around contributions and discussions.
Clear monetization path through team plans and private workspaces.

Risks

Free alternatives like Miro, Lucidchart, and GitHub-hosted diagrams already solve the core need for many users.
Content creation and curation is labor-intensive and requires deep technical knowledge to maintain quality.
Difficult to differentiate from existing design tools that added templates and examples.
Engineers may prefer learning from books, courses, or their own experience over browsing an atlas.
Network effects are weak, so growth depends on marketing rather than viral adoption.
Solo founder will struggle to maintain content quality and keep diagrams current as technology evolves.

Fly Labs Method

Is the pain real, is there a gap, is it the right time, can one person build it.

Buildability: 57

System designers feel real friction finding reference architectures, but existing solutions partly address this and users may not convert to paid offerings.

Value Equation

Dream outcome and how likely it feels, against the time and effort it costs.

52

The market exists but is fragmented across free resources, making it hard to charge enough to build a sustainable business at solo founder scale.

One-Person Business

Curiosity pull, identity fit, and a path from free value to paid for a solo creator.

61

Engineers value learning system design but typically consume free content first, limiting willingness to pay unless the tool solves a specific workflow problem they face daily.

Viral Frameworks

Hook strength, shareability, and how cheaply it can be tested.

54

The idea targets a real audience but lacks a clear unfair advantage, defensibility, or network effects that would prevent competitors from copying the concept.

Builder Lens

Evidence the problem exists, timing, defensibility, and a model that fits on a napkin.

49

This is a content and education play in a crowded space without obvious venture scale or a mechanism to grow exponentially beyond initial users.

Five lenses, one composite. How scoring works

The angle

Start by scraping and organizing existing public system design case studies into a searchable database with standardized diagram formats. Add interactivity so users can toggle components on and off to understand dependencies. Charge teams or enterprises for private diagram storage and collaboration features.

Every CEO and CFO change at US public companies, live from SEC

Built this solo. It watches SEC filings for executive and board changes, extracts the data, and shows it in real time. 2,100+ changes in the last 30 days. The comp data is interesting: average new CEO total comp is $8.4M across 284 appointments. The /explore page is fully open, no login needed.

µJS, a 5KB alternative to Htmx and Turbo with zero dependencies

I built µJS because I wanted AJAX navigation without the verbosity of HTMX or the overhead of Turbo.It intercepts links and form submissions, fetches pages via AJAX, and swaps fragments of the DOM. Single <script> tag, one call to `mu.init()`. No build step, no dependencies.Key features: patch mode (update multiple fragments in one request), SSE support, DOM morphing via idiomorph, View Transitions, prefetch on hover, polling, and full HTTP verb support on any element.At ~5KB gzipped, it's smaller than HTMX (16KB) and Turbo (25KB), and works with any backend: PHP, Python, Go, Ruby, whatever.Playground: https://mujs.org/playgroundComparison with HTMX and Turbo: https://mujs.org/comparisonAbout the project creation, why and when: https://mujs.org/aboutGitHub: https://github.com/Digicreon/muJSHappy to discuss the project.
