AI Dev Hub

What it does

I built AI Dev Hub because I was tired of opening 10 tabs just to do simple dev tasks. It’s now a growing collection of 100+ free tools for developers and AI builders, format/convert/debug workflows, compare models and pricing, generate configs, test prompts/schemas, and more. Everything runs in the browser, no signup, no paywall, no data collection, no ads. Big focus for me is making tools that are actually useful in real workflows and making the site increasingly agent-friendly.

247 free developer & agent tools — JSON formatter, token counter, regex tester, AI pricing calculator, and REST APIs. Run in your browser, no signup.

247 browser-native tools and REST APIs for developers and the agents they build. No signup, no keys — run the computation in a tab or call the endpoint. Validate robots.txt and llms.txt files, detect conflicts, simulate AI bot access, and export corrected policies Convert one canonical skill definition into OpenClaw SKILL.md, Claude blocks, Codex scaffolds, and MCP manifest snippets Validate robots.txt and llms.txt files, detect conflicts, simulate AI bot access, and export corrected policies Scan SKILL.md instructions for destructive command patterns, missing safety boundaries, and trust posture Test and debug regular expressions with live matching, capture group extraction, and…from aidevhub.io

In the maker’s words, at launch

I built 75 developer and AI tools as a single static site. Everything runs in the browser, no cookies, no ads, nothing gets sent to a server. The tools range from the usual suspects (JSON formatter, base64 encoder, regex tester) to some AI-specific ones I couldn't find good free versions of bundled in one suite…

  My Attempt to Organize the World of AI Dev Tools2025 · aicode.danvoronov.com · ▲101

  I've been exploring the (not so=) amazing potential of AI in coding and have compiled a list of tools. From AI-powered IDEs to code generators, this resource is my contribution to the community. I'm still on the fence about including txt2sql projects, as their functionality seems too basic to me. And I'm personally maintaining this, so your feedback is wellcome.

  I built an AI tools hub with 70 categorized and reviewed apps2025 · toolsverse.tools · ▲10

  Over the last 3 weeks, I built a website to organize 70+ AI tools into a searchable, reviewed, and categorized hub. Use case: I was constantly sharing AI tools with friends & colleagues, but the available directories felt outdated, shallow, or spammy. So I built my own: - Tools are categorized (e.g. writing, voice, code, automation) - Marked clearly as free/paid - Includes brief reviews, ROI notes, and usage tips - Fully searchable and updated daily - Working on tool ratings, comparisons, and a “trending” leaderboard Website: https://www.toolsverse.tools/ I’d love…

  i built an AI code reviewer for github (used it on itself during dev)2025 · codii.dev · ▲6

  I’ve spent the last 2.5 months building a product that runs LLM-powered code reviews on my pull requests — and I just launched it. The tool is built specifically for solo developers. You install it on your repo, trigger a scan by creating a pull request, and it leaves structured review comments using OpenAI under the hood. Funnily enough, I used the dev version of this app to review its own pull requests while building it. It helped me spot bugs, simplify structure, and keep quality high — all with minimal need for another human in the loop. Things I want to try out in the next months : -…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
