24 alternatives to CT Logs Search Engine
I recently launched https://www.merklemap.com/, a tool designed to leverage Certificate Transparency logs for enhanced domain monitoring. Example query https://www.merklemap.com/search?query=example&page=1 Key features of MerkleMap: - Near real-time ingestion of CT logs - Full-string subdomain search capability - Support for an arbitrary number of wildcards in searches While the current functionality focuses on subdomain discovery, I'm planning to expand MerkleMap into a comprehensive CT log monitor over time. I'd love to hear your feedback.

Hi HN! This started late last year as an afternoon project to play around with ElasticSearch, and then I kept thinking of new features I wanted to add. I still have a lot of things I want to build, but now seemed like a good time to put it out there: even if the results aren’t nearly the quality I’d like, I’ve still found it useful and I want to show it off! I’ve been working on it since September 2021, but only in fits and starts. The entire thing runs on a computer in my living room (there’s a picture on the About page); I haven’t done any load testing so we’ll see how it holds up.

hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to register for certain keywords and get notified when something new shows up for that search. would…

I built this tool because I wanted a way to just take a bunch of URLs or domains, and query their content in RAG applications. It takes away the pain of crawling, extracting content, chunking, vectorizing, and updating periodically. I'm curious to see if it can be useful to others. I meant to launch this six months ago but life got in the way...

This can be used to find phishing domains or domains matching any pattern you want if you select "custom filter." You can also connect over WebSocket at /ws and use any programming language you want. There may be duplicates because some domains are published in multiple logs. I get data from all of the logs currently included with Chrome, a list of which is available here: https://github.com/google/certificate-transparency-community....

Hi HN! We’re Ethan and Danny, the authors of Tangent (https://github.com/telophasehq/tangent), a Rust-based log pipeline where all normalization, enrichment, and detection logic runs as WASM plugins. We kept seeing the same problems in the OCSF (https://ocsf.io) community: 1) Schemas change constantly. Large companies have whole teams dedicated to keeping vendor→OCSF mappings up to date. 2) There’s no shared library of mappings, so everyone recreates the same work. 3) Writing mappers is tedious, repetitive work. 4) Most pipelines use proprietary DSLs that are…

Hey HN! I’m Karan, creator of Logchef (https://logchef.app), an open-source log viewer built specifically for exploring logs stored in ClickHouse. This tool grew directly out of my $day job managing massive log volumes. Like many orgs, we migrated our log workloads to ClickHouse for its performance, but found the ecosystem lacked dedicated UI tooling for actually browsing and analyzing those logs effectively. We were using Metabase, and while great for general BI, it wasn't designed for log exploration workflows. Common pain points included: - Clunky Ad-hoc Querying:…

I built qlog because I got tired of waiting for grep to search through gigabytes of logs. qlog uses an inverted index (like search engines) to search millions of log lines in milliseconds. It's 10-100x faster than grep and way simpler than setting up Elasticsearch. Features: - Lightning fast indexing (1M+ lines/sec using mmap) - Sub-millisecond searches on indexed data - Beautiful terminal output with context lines - Auto-detects JSON, syslog, nginx, apache formats - Zero configuration - Works offline - Pure Python Example: qlog index './logs/*/*.log' qlog search "error"…

We have finally launched Domfetch! Domfetch is a free platform to find expired domains. Users can search through domains that are (almost) available for registration. We enrich these domains with extra data to help users find valuable domains. We created this tool because we found the (free) alternatives lacking certain data, such as Moz, Alexa history (we check 5 years of data) & search volume history over a period of 1 year. Let us know what you think! More features and tld's will be added in the near future.

I don't like the existing query languages for Elasticsearch and Grafana Loki, because they are too awkward to use for typical logs' investigation cases. So I designed new query language - LogsQL - and wrote reference implementation for it as a part of VictoriaLogs - an open source database for logs. LogsQL is based on the following principles: - Simplicity. It is easy to write typical queries over logs in it. For example, a single word `error` is a valid LogsQL query, which returns all the logs with the `error` word. Another example is `_time:5m error`, which returns all the logs with the…

A few weeks ago I posted an early version of this. It was just an MCP doing web search for AI assistants. Since then it evolved rapidly. The problem I kept running into is that when I use an LLM for research, it gives me citations that look right but aren't most of the time. Sometimes the paper doesn't exist. Sometimes it does exist but it's been retracted. Most times the sources are not fully vetted nor truly relevant to my search. I got tired of checking these manually. That's why I built this updated MCP. It looks the work up in Crossref to confirm it's real. It checks the Retraction…

Hi HN, I built DomainExplorer.io, a search and analytics tool that lets you explore newly registered and expired domains across all TLDs — updated daily. The idea came from my frustration how hard it is to search for registered/expired domains. I wanted a simple and easy-to-use tool with web UI where you could submit queries like: - Find all domains in .com and .net zones that end with "chatgpt". - Find all expired domains that have "copilot" substring in name (excluding .ai and .io zones) and their name is shorter than 12 symbols - Find all domains with "amazon" in name and that were…
