Cal.diy: open-source community edition of cal.com

📝 Discussion Summary (Click to expand)

Theme 1 – Skepticism about the security rationale for closing the source

"If you believe they really did it for security, I have a very nice bridge to sell you for an extremely low price ..." – hungryhobbit

Theme 2 – Open‑source provides stronger security through community scrutiny

"Open source benefits from white‑hat scanning for vulnerabilities, while closed source does not..." – rectang

Theme 3 – Community reaction and emergence of alternatives > "I am now actively rooting for cal.com to go out of business now as a cautionary tale for any company thinking about taking open source projects proprietary." – lrvick


🚀 Project Ideas

Open‑Source Security ProvenanceDashboard

Summary

  • An AI‑driven service that continuously scans public repositories for known vulnerabilities, license changes, and emerging threats, then generates a public security‑posture dashboard.
  • Gives developers and users a transparent, trustworthy view of a project’s security health, counter‑acting “security through obscurity” claims.

Details| Key | Value |

|-----|-------| | Target Audience | Open‑source maintainers, security teams, investors, and end‑users | | Core Feature | Real‑time vulnerability scanning + interactive security dashboard | | Tech Stack | Python (FastAPI), React, Docker, GitHub Actions, Snyk/Trivy APIs | | Difficulty | Medium | | Monetization | Revenue-ready: Subscription tiers (Free community, Pro $19/mo, Enterprise $99/mo) |

Notes- HN users repeatedly ask “why close source if AI can scan it anyway?” – this provides the answer with hard data.

  • Could spark discussion on the real cost of security versus the marketing spin.

Community Fork Guardian

Summary

  • A hosted platform that automatically forks a project when its maintainer announces a closed‑source transition, then continuously syncs upstream changes, builds CI pipelines, and offers a simple sponsorship workflow.
  • Turns a potential “bait‑and‑switch” into a sustainable, community‑owned continuation.

Details

Key Value
Target Audience Maintainers of abandoned OSS, contributors, and end‑users seeking continuity
Core Feature Automatic fork detection, sync, CI, and sponsorship marketplace
Tech Stack Node.js (Nest), PostgreSQL, GitHub GraphQL, Stripe API
Difficulty High
Monetization Revenue-ready: Transaction fee 2% on sponsorship payouts, plus a $5/mo “maintenance” plan

Notes

  • Directly addresses comments like “who decides which fork is the ‘community edition’?” and “I’m rooting for the project to go out of business.”
  • Generates lively debate about stewardship models and licensing responsibilities.

Secure Self‑Host Scheduler Builder#Summary

  • A CLI tool that packages any open‑source calendar/scheduler (e.g., cal.diy, NeetoCal) into a hardened, audited Docker image with built‑in vulnerability monitoring, automatic updates, and a one‑click self‑host deployment guide.
  • Makes the migration from hosted SaaS to self‑hosted, secure instances painless and transparent.

Details

Key Value
Target Audience DevOps engineers, small teams, privacy‑focused organisations
Core Feature Auto‑generate secure Docker images, CI/CD test suite, and update alerts
Tech Stack Rust (Docker SDK), Bash, GitHub Dependabot, Terraform
Difficulty Low
Monetization Hobby

Notes

  • Resonates with HN complaints about “Why open the source but then strip Docker images?” and calls for practical, usable alternatives.
  • Sparks conversation on the real‑world steps needed to self‑host safely without vendor lock‑in.
