24 alternatives to SQRL – Anti-spam rules language Twitter acquired in 2018, open-sourced

Hey all, author here! This is a demo of the rules engine we built to fight spam/abuse on the internet. It was built based on learnings from Facebook & Google, while trying to make a language that makes it simple for anti-spam analysts to quickly (and safely) deploy rules to production. Unfortunately it looks like the Twitter event feed is temporarily down (they're blocking it, possibly as part of shutting down the API on Thursday). I have a cache of events from a little earlier that I'm going to try play through the stream.

SQRL is an open-source rules language for detecting and preventing spam and abuse online. Originally developed by Twitter and based on approaches used by Facebook and Google, it enables anti-spam analysts to create and… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    Hello, My name is Yahia, I've been working on scraping products for a long time and maintain a couple of free sites in my spare time (E.g. knifegeek.io) What prompted this is i've rebuilt scraping infra at every company I've started and finally just made it a product. Pass a URL, get clean markdown, html, images, sitemap or pass a domain, get logos, colors, socials, industry data. Goal is to offer a better service than VC funded competitors at a fraction of the cost. Stealth is included and automatic at no additional cost (normally an upcharge by alternatives). Would love your honest thoughts.

    I previously did a Show HN late Dec 2020: https://news.ycombinator.com/item?id=25470672 That was a great experience and in the past year I continued to develop the site to bring it to a level of stability and maturity that I felt necessary for it to have a chance to succeed. Sqwok is all about answering the question: Can we have better open conversations on the internet? I wasn’t satisfied with the existing means of discussing topics such as culture, history, politics, and technology through threaded comments, and was simultaneously impressed with Slack bringing the IRC…

    hi friends! i'm pretty tired of engagement bait and all the political nonsense on my x/twitter feed. i was curious if i could use an llm to filter out these type of content, so i prototyped a quick chrome extension. it uses LLama 3.3 to analyze the tweet through https://groq.com/ (because they are super-super fast). the extension is available in the chrome store, also there is a link to the repo. - you can tweak the system prompt for the filtering - but you need your own API key from Groq (you can get one for free)

    Lately I've felt exhausted due to the deluge of AI/GPT posts on hacker news, and have seen similar grumblings. I threw together this frontend that filters out anything with the phrases AI, LLM, GPT, or LLaMa for use until the hype dies down a bit. Before anyone asks, yes I did try to use ChatGPT to help, and while the code it provided was helpful, it needed some heavy bug-fixing. Edit: One other note I forgot to mention. The favicon is generated by Stable Diffusion, I asked it to generate an "Aritificial Intelligence Favicon", and then I added the red circle with line through it.

    A few days ago I saw this tweet from PG: https://twitter.com/paulg/status/1496549841912094733 ...and guessed it shouldn't be too hard to make a chrome extension to do this (I had never made a chrome extension before) So I took a stab at it - took me a bit over a day to make it, and it was fun to put together. I responded to his tweet with the link to the extension but I'm not sure if he would've seen it. edit: Looks like I missed the approval notification for the listing of this extension on the chrome store:…

    Hey guys, I made a post about this about a week ago and was told to create a Show HN post. So here we are! Squabblr is a hybrid that takes Twitter style posting and combines it with Reddit style commenting. It came up from a personal want where I liked using Twitter to see what people I'm interested in are up to, but found that the reply system left a lot to be desired. It's very hard to have or follow conversations with their UI. While Reddit provided a great commenting system but didn't support following people very well (or had much usage of it at all). So I decided to create Squabblr.…

    I've launched the new product, xhr.dev (https://xhr.dev/) The initial product is a 1 line code integration that does bot detection avoidance via a forward proxy. Ideal customer is someone who gets blocked by anti-bot defences like cloudflare or other captcha challenges. Usually these customers have web scraping use cases. You can view our historical performance on our status page (https://status.xhr.dev). ty v much, john

    Hi HN :) really excited to share this with you. The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels…

    We built a Chrome extension and iOS app that filters Twitter's feed using Qwen3.5-4B for contextual matching. You describe what you don't want in plain language—it removes posts that match semantically, not by keyword. What surprised us was that because Twitter's ranking algorithm adapts based on what you engage with, consistent filtering starts reshaping the recommendations over time. You're implicitly signaling preferences to the algorithm. For some of us it "healed" our feed. Currently running inference from our own servers with an experimental on-device option, and we're working on fully…
