Writing code is cheap now

📝 Discussion Summary (Click to expand)

1. Writing code is cheap, but good code is still expensive

“Writing code has always been cheap. Writing good code remains significantly more expensive.” – spockz
“Code is a liability, not an asset.” – malfist

2. AI accelerates delivery but introduces new quality & maintenance burdens

“The skill is mastering the craft of directing cheap inputs toward valuable outcomes.” – kneel25
“You still have to review and validate that it works… the cost of reading code is the same as it always was.” – noduerme

3. The job market is shifting: fewer traditional roles, more AI‑centric teams

“The job market is not an employee market.” – Ronsenshi
“We’ll see a wave of startups using AI to replace teams.” – sjaiisba

4. Technical debt and maintainability become the real bottleneck

“Code is a liability, not an asset.” – malfist
“AI‑generated code can create huge technical debt.” – frizlab

5. New habits, processes, and infrastructure are required to keep up

“We need to figure out how to build systems in a way that it can keep up with this increased influx of code.” – the_mitsuhiko
“We need new habits and infrastructure.” – the_mitsuhiko

6. The debate over accepting low‑quality, “vibe‑coded” software continues

“We are seeing a shift towards accepting crappy code.” – frizlab
“We need to maintain quality, not just speed.” – simonw


🚀 Project Ideas

AI Code Review Assistant

Summary

  • Automates review of AI‑generated code, flagging bugs, style violations, missing tests, and potential security issues.
  • Provides actionable feedback and suggested patches, reducing the manual review burden on senior engineers.

Details

Key Value
Target Audience Teams using LLMs for code generation (startups, SREs, open‑source maintainers)
Core Feature LLM‑powered code review engine that parses diffs, runs static analysis, and generates review comments
Tech Stack Python, FastAPI, OpenAI/Anthropic API, ESLint/Clang‑tidy, GitHub Actions
Difficulty Medium
Monetization Revenue‑ready: $49/month per repo, tiered for enterprise

Notes

  • HNers lament “AI code is buggy and hard to review” (e.g., “I have to re‑review AI code to make sure it works”). This tool turns that pain into a quick, repeatable process.
  • Sparks discussion on best‑practice AI code reviews and the role of LLMs in quality assurance.

AI Debugger

Summary

  • Executes failing tests, isolates the buggy code path, and proposes minimal patches or test‑driven fixes.
  • Bridges the gap between AI‑generated code and human debugging workflows.

Details

Key Value
Target Audience Developers who rely on AI for rapid prototyping and need fast debugging
Core Feature Automated test runner + LLM‑guided patch generator that suggests code changes to fix failures
Tech Stack Node.js, Jest/pytest, Docker, OpenAI API, GitHub Actions
Difficulty Medium
Monetization Revenue‑ready: $29/month per user, optional enterprise license

Notes

  • Reflects comments like “I have to debug AI code every time it fails” and “AI code is hard to understand”.
  • Provides a practical utility for teams that want to keep the speed of AI while maintaining reliability.

Legacy Code Analyzer & Refactorer

Summary

  • Scans legacy codebases, auto‑generates documentation, identifies dead code, and produces refactor suggestions or rewrites using LLMs.
  • Helps teams modernize code without manual reverse engineering.

Details

Key Value
Target Audience Maintainers of large, poorly documented codebases (e.g., legacy Java, C++)
Core Feature Static analysis + LLM‑driven refactoring engine that outputs clean, typed code and docs
Tech Stack Java/Kotlin, Python, OpenAI API, Doxygen, SonarQube
Difficulty High
Monetization Revenue‑ready: $199/month per project, custom enterprise contracts

Notes

  • Addresses frustration “Legacy code is hard to understand and maintain” and “AI can help reverse engineer code”.
  • Enables discussion on how AI can reduce technical debt in mature systems.

Domain‑Specific AI Code Generator

Summary

  • Provides a specialized LLM harness tuned for safety‑critical or embedded domains (e.g., Rust for IoT, Ada for avionics).
  • Enforces language‑specific safety checks, real‑time constraints, and compliance standards.

Details

Key Value
Target Audience Embedded engineers, safety‑critical developers, regulatory teams
Core Feature Domain‑tuned prompt templates, static analysis integration, compliance checklists
Tech Stack Rust, Ada, Python, OpenAI API, static analyzers (Clang‑sa, Mypy), CI pipelines
Difficulty High
Monetization Revenue‑ready: $99/month per domain license, enterprise tier

Notes

  • Resonates with “AI code must meet strict safety and performance constraints” and “generic AI code is not suitable for embedded”.
  • Encourages debate on the limits of LLMs in regulated industries.

AI Code Quality Dashboard

Summary

  • Aggregates static analysis, test coverage, complexity metrics, and LLM‑generated quality scores into a single dashboard.
  • Gives teams visibility into the health of AI‑generated code over time.

Details

Key Value
Target Audience DevOps teams, QA leads, product managers
Core Feature Real‑time metrics, trend analysis, alerts for quality regressions
Tech Stack Go, Grafana, Prometheus, OpenAI API, SonarCloud
Difficulty Medium
Monetization Revenue‑ready: $59/month per repo, enterprise add‑ons

Notes

  • Meets the need for “measuring quality of AI code” and “tracking technical debt”.
  • Provides a practical tool for teams to justify AI adoption and monitor its impact.

Deterministic AI Code Generation Service

Summary

  • Guarantees reproducible code generation by anchoring prompts to a versioned knowledge base and deterministic token sampling.
  • Enables version control of AI‑generated code and rollback of changes.

Details

Key Value
Target Audience Teams that require reproducibility (CI/CD, regulatory compliance)
Core Feature Prompt versioning, deterministic sampling, code hash tracking, rollback API
Tech Stack Rust, OpenAI API, Git, Docker, Terraform
Difficulty High
Monetization Revenue‑ready: $149/month per project, enterprise licensing

Notes

  • Addresses concerns like “LLM outputs are non‑deterministic and hard to reproduce” and “need for reproducible builds”.
  • Sparks discussion on best practices for AI‑driven development pipelines.
