Free interview prep tool built by someone who couldn't afford paid alternatives, targeting cost-sensitive job seekers.
The pain
The gap
Build angle
Strengths
- Founder has direct experience with the pain point—understands what free users actually need
- Design/creative is underserved compared to tech/finance interview prep
- Free model creates network effects if community participation works
- Low barrier to initial traction among cost-sensitive early-career designers
Risks
- Freemium conversion is notoriously difficult; most users won't pay even if premium features exist
- Quality control at scale—community feedback can be inconsistent or unhelpful without moderation
- Paid competitors have resources to build free tiers and undercut positioning
- Design interview prep is a smaller TAM than tech/finance; harder to reach critical mass
- No clear revenue model articulated; sustainability unclear without paying users
Fly Labs Method
Is the pain real, is there a gap, is it the right time, can one person build it.
Value Equation
Dream outcome and how likely it feels, against the time and effort it costs.
One-Person Business
Curiosity pull, identity fit, and a path from free value to paid for a solo creator.
Viral Frameworks
Hook strength, shareability, and how cheaply it can be tested.
Builder Lens
Evidence the problem exists, timing, defensibility, and a model that fits on a napkin.

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.
