I've updated my Linux System Call website and API
I first released those in back in 2020 and now I finally added more architectures, Kernel selector, syscall descriptions and a few other niceties. It should work a bit better on mobile devices too but I am no CSS expert.The API is at https://api.syscall.sh

A developer tool and API providing detailed Linux syscall information across architectures with improved usability.
The pain
The gap
Build angle
Strengths
- Clear technical need among Linux developers
- Expanded architecture and kernel support
- API availability for integration
- Single developer build and maintenance feasible
Risks
- Niche market limits growth and monetization
- Uncertain willingness to pay for the service
- Limited UI/UX polish may reduce adoption
- Competition from existing syscall documentation and tools
Fly Labs Method
Is the pain real, is there a gap, is it the right time, can one person build it.
- Problem clarity

- Solution gap
- 60
- Willingness to pay
- 50
- Buildability
- 80
The problem is clear for developers needing syscall info, but the market is niche and willingness to pay is uncertain; the product is feasible for one person to build.
Value Equation
Dream outcome and how likely it feels, against the time and effort it costs.
The value to users is moderate as it solves a specific technical need, but the market size and monetization potential are limited.
One-Person Business
Curiosity pull, identity fit, and a path from free value to paid for a solo creator.
The idea addresses a real developer pain point but lacks strong differentiation and clear monetization strategy.
Viral Frameworks
Hook strength, shareability, and how cheaply it can be tested.
The tool improves on an existing resource with added features, but the target audience is small and growth potential limited.
Builder Lens
Evidence the problem exists, timing, defensibility, and a model that fits on a napkin.
The project is technically solid and useful for a niche audience but does not demonstrate strong traction or a scalable business model.
Five lenses, one composite. How scoring works
The angle

Excessive CAPTCHA challenges degrading GitHub login UX for enterprise users
GitHub's anti-bot protection forces users, especially those with organizational emails, to solve 10 blurry puzzles multiple times, creating an extremely painful and frustrating user experience.

GTA modders tediously manually edit assembly files for modpacks

BreezePDF – Free, in-browser PDF editor
BreezePDF lets you edit, sign, merge, compress, redact, OCR, fill forms, extract tables, and use 30+ more PDF tools — all in the browser, no sign-up. Files never leave your computer.I built it because when people search Google for common PDF tasks, many of the tools they find upload documents to a server. I wanted an option that keeps files local instead.I posted an earlier version on HN last spring: https://news.ycombinator.com/item?id=43880962At the time it only supported a small set of features. Over the last 10 months I rebuilt large parts of it and expanded it to nearly 40 tools, including several ideas that came from comments in that earlier thread.There is also now a desktop app for macOS, Windows, and Linux, plus a CLI/SDK for developers.
