14. webappanalyzer

    12 4 589 9.2 Python

    Project mention: How to detect any website's tech stack in bulk (and why a real browser finds 2x more) | dev.to | 2026-10-01

    Every tool leaves traces. The open-source webappanalyzer project (a community continuation of the old Wappalyzer data) catalogs 7,600+ technologies with patterns like:

15. A11Y.md

    13 3 467 8.9 Python

    Project mention: A11Y.md 2.0: what shipped when the numbers, not the author, decided | dev.to | 2026-08-28

    Two weeks ago I did something slightly terrifying: I put my own open source project inside a formal study — two preregistered, placebo-controlled experiments measuring whether A11Y.md actually changes what AI agents build. I published everything, including the parts where I didn't win.

16. mira

    14 2 366 9.7 Python

    Self-hosted AI code reviewer with indexed PR reviews, walkthroughs, vulnerability scanning, dependency graphs, custom rules, and a learning loop. (by miracodeai)

    

    Project mention: Ask HN: What tools are you using for AI-assisted code review? | news.ycombinator.com | 2026-06-19

    Co-founder of Mira [1] here.

    This is exactly what we built Mira for. It's self-hosted, bring-your-own-model/BYOK, and most importantly, open source.

    You point it at your own API keys (e.g. OpenRouter or a local model) so nothing leaves your infra, and it runs as a code reviewer on PRs.

    It's also ridiculously quick at reviewing (benchmarks at ~77s) because your PRs aren't sitting in a queue on a cloud somewhere (alternatives are > 5 minutes)

    We're working really closely with our users to build the best possible code reviewer. Feedback and contributions are highly encouraged.

21. sugar

    19 5 98 8.9 Python

    Persistent memory for AI coding agents. Local-first, cross-session context, global knowledge, and optional autonomous task execution. (by roboticforce)

    

    Project mention: Ask HN: What are tools you have made for yourself since the advent of AI | news.ycombinator.com | 2026-06-08

    1. Built an agent memory tool since all agents and clis are dumb and don't remember anything. Instead of prepping 300 project files and Md files I just say:

    Check sugar memory for the latest thing we were working on.

    2. The second thing is when making changes across a large codebase agents are also dumb at figuring this out and also grep 300 things, using tons of tokens. Instead I say

    Check RemembrallMCP to analyze the impact of the change.
