What it does

Open-source linter for programmatic SEO. Paste a URL or gate it in CI: pseolint finds the doorway clusters, near-duplicates, and thin templates that trip SpamBrain, by template. Free tier + $19/mo Pro monitoring.

pseolint is the open-source linter for programmatic SEO. Paste a URL or drop it in CI: it finds the doorway clusters, near-duplicates, and thin templates that trip SpamBrain, then tells you which template to fix: one fix, N pages. It also flags which pages can get cited in ChatGPT, Perplexity, and Google AI Overviews. We fetch up to 50 pages anonymously (200 signed in) over a few minutes: if it's your site and it's cache-cold, warm it first. Analytics-safe: audit runs won't touch your GA, PostHog, Mixpanel, or session-replay dashboards. ↑ Each tile = one page. Color = worst rule that fires on that page. Watch the identity mark in the nav. City × service grids, directories, state × fee…from pseolint.dev

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…

  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…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
