Open Source Isn't Dead. Cal.com Just Learned the Wrong Lesson

📝 Discussion Summary (Click to expand)

Prevalent Themes in the Discussion

  1. Closing source is being used as an excuse rather than a genuine security necessity

    “Spineless bullshit excuse instead of owning your choices.” – funvill
    “Blaming AI here feels like cover.” – ahmedallam2

  2. AI‑driven vulnerability discovery changes the security calculus

    “Given what the clankers can do unassisted and what more they can do when you give them ghidra, no software is ‘closed source’ anymore.” – baq

  3. Business viability drives the licensing shift; open‑core is no longer sustainable

    “Separating codebase and leaving ‘cal.diy’ for hobbyists is pretty much the classic open‑core path. The community phase is over and they need to protect their enterprise revenue.” – p_stuart82

VulnGuard AI

Summary

  • Continuous automated AI security scanning for open‑source and private repositories, delivering real‑time vulnerability reports and remediation guidance.
  • Gives maintainers a transparent security posture they can publish, addressing the “excuse to close source” frustration.

Details

Key Value
Target Audience Open‑source maintainers, DevOps teams, security engineers
Core Feature AI‑driven code and binary analysis, continuous integration alerts, public security dashboard
Tech Stack Backend: Python, FastAPI; Scanning: Ghidra + LLM embeddings; Frontend: React; DB: PostgreSQL; CI: GitHub Actions
Difficulty Medium
Monetization Revenue-ready: $19 per month per repository

Notes

  • HN commenters repeatedly mention AI scanners as a looming threat; this tool turns that into a proactive service.
  • Low friction for projects to publish their audit results, fostering trust without closing source.

OpenCore Bridge

Summary

  • A lightweight SaaS marketplace that lets open‑source projects monetize premium services (support, hosting, custom features) while keeping the core code fully open.
  • Solves the “can’t make money without closing” dilemma highlighted by Cal.com’s CEO.

Details

Key Value
Target Audience Open‑source maintainers, small SaaS startups, indie developers
Core Feature Subscription tiers, revenue split, licensing badge, community governance dashboard
Tech Stack Full‑stack: Node.js/Express, GraphQL, Redis; DB: MongoDB; Auth: OAuth; Frontend: Vue
Difficulty Low
Monetization Revenue-ready: 5% transaction fee on each payment

Notes

  • Directly addresses comments like “blaming AI here feels like cover” by providing a legit monetization path.
  • Enables community to support projects without forcing a license change, preserving the “many eyes” benefit.

Binary2Source AI

Summary

  • Upload compiled binaries (e.g., ELF, PE) and receive AI‑generated high‑level source‑like representations plus automated vulnerability highlights, bridging the gap for closed‑source security audits.
  • Turns the “AI can’t find vulnerabilities without source” argument into a useful service.

Details

Key Value
Target Audience Security researchers, closed‑source vendors, reverse‑engineers, bug‑bounty platforms
Core Feature Binary disassembly + LLM reconstruction, CWE mapping, exportable report
Tech Stack Backend: Rust + Capstone + Tiktoken‑based LLM pipeline; Frontend: Next.js; Storage: S3
Difficulty High
Monetization Revenue-ready: $0.01 per MB of binary processed

Notes

  • Frequently discussed in HN as “AI can read binaries, making source unnecessary”; this product formalizes that capability.
  • Provides a tangible alternative to closing source, letting companies keep IP while still offering security transparency.
