An automated tool for pentesters to reliably enumerate live subdomains and populate Burp Suite's sitemap, addressing current tool shortcomings.
The pain
The gap
Build angle
Strengths
- Addresses a specific, frequently felt, and high-severity pain point for a professional audience.
- Clear user frustrations with existing solutions provide concrete areas for improvement.
- Growing market for offensive security and attack surface management tools.
- The value proposition of saving significant time for highly paid professionals is strong.
Risks
- High build complexity for a solo founder, requiring deep technical knowledge in DNS, networking, and Burp Suite APIs.
- Crowded space with powerful open-source alternatives and established commercial players, making differentiation challenging.
- Potential for pricing sensitivity due to the prevalence of free tools that solve parts of the problem.
- Continuous maintenance might be required to keep up with new enumeration techniques and Burp Suite updates.
Next steps
- Conduct in-depth interviews with 10-15 offensive security professionals to confirm the severity of the pain and willingness to pay for a commercial solution.
- Validate the specific features that would justify a paid product over existing free tools, focusing on reliability and completeness.
- Develop a proof-of-concept for the most difficult part of the problem (e.g., reliably finding subdomains missed by Amass or Subfinder) to assess buildability risks.
- Research potential pricing models and customer acquisition channels within the pentester community.

The idea addresses a real and specific pain point for pentesters, with clear gaps in existing solutions regarding integration and reliability. However, the build complexity and crowded market for underlying components make it a challenging solo project.
Value Equation
Dream outcome and how likely it feels, against the time and effort it costs.
This idea targets a real, paying pain, but faces challenges in differentiation against strong free and commercial alternatives, and high build complexity for a solo founder.
One-Person Business
Curiosity pull, identity fit, and a path from free value to paid for a solo creator.
The problem is clear, but the complexity, competition, and need for deep domain expertise make it a difficult solo endeavor with moderate monetization potential.
Viral Frameworks
Hook strength, shareability, and how cheaply it can be tested.
A clear value proposition for a specific, reachable audience exists, but validation is needed to confirm willingness to pay for a commercial solution over strong free tools.
Builder Lens
Evidence the problem exists, timing, defensibility, and a model that fits on a napkin.
This idea solves a tangible, frustrating problem for a specific user, with a clear narrow wedge and potential for significant time savings.

Market signals
The market for automated offensive security tools, particularly in subdomain enumeration and attack surface management, is growing. Recent funding rounds indicate significant investor interest in AI-powered solutions for vulnerability detection and continuous penetration testing. The emphasis is on streamlining and accelerating the reconnaissance phase to keep pace with the increasing speed of cyberattacks and code development.
What frustrates people
- Censys is commodified and too focused on ASM service, with a smoother UI and better customer support in Criminal IP.
- Amass can miss subdomains hidden behind weird DNS configs, rate limits, or non-standard structures.
- Amass users often run it with default settings, leading to similar results as other hackers.
- Subfinder has struggled to keep pace with the growing number of independent API sources.
- Subdomain bruteforcing with Burp Suite is slow.

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.
