24 alternatives to Open-Source Data Anonymization for Developers
Hey HN, we're Evis and Nick from Neosync (https://www.github.com/nucleuscloud/neosync). Since we last introduced Neosync on HN 4 months ago, we’ve made a lot of progress and we’re excited to be launching several new features. As a reminder, Neosync is an open source platform that helps developers anonymize production data, generate synthetic data, subset it and sync it across their environments for better testing, debugging and developer experience. We do all of this while handling referential integrity. Whether you have primary keys, foreign keys, unique constraints,…

Hey HN, we're Evis and Nick and we're excited to be launching Neosync (https://www.github.com/nucleuscloud/neosync). Neosync is an open source platform that helps developers anonymize production data, generate synthetic data and sync it across their environments for better testing, debugging and developer experience. Most developers and teams have some version of a database seed script that creates some mock data for their local and stage databases. The problem is that production data is messy and it’s very difficult to replicate that with mock data. This causes two big…

Hey HN, we're Evis and Nick, we're excited to be launching Neosync on HN! Neosync is an open source data replication and anonymization project that helps developers create safe, anonymized test data and sync it across all environments for high-quality local, stage and CI testing. This is how it works: 1. You select a job type. Today we support data sync jobs (these sync data between two databases and run on a schedule you define) and a data generation job (this generates synthetic data from scratch and sends it to a destination). 2. Next you define your source database and a destination(s)…

Hey HN -- thanks for showing interest in this. Happy to collaborate on this project. I'm hoping to get it stable soon so my own family can start using it. I've been working on this for about 10+ years, nights and weekends. It's been really slow going since I only have my own personal data to test it with. I just don't love that my data is primarily stored on someone else's computer up in the cloud. I want my own local copy at least. And while I can download exports from my various accounts, I don't want them to just gather dust and rot on my hard drive. So, Timelinize helps keep that data…

Hi! My name is Vadim, and I’m the developer of Greenmask (https://github.com/GreenmaskIO/greenmask). Today Greenmask is almost 1 year and recently we published one of the most significant release with new features: https://github.com/GreenmaskIO/greenmask/releases/tag/v0.2.0, as well as a new website at https://greenmask.io. Before I describe Greenmask’s features, I want to share the story of how and why I started implementing it. Everyone strives to have their staging environment resemble production as closely as possible…

I built this last year but never posted it anywhere, but now with Reddit hiatus it seems like the right time to give it a shot. The main goal of zsync is to foster high quality content and discussion. That's it. If it can't accomplish that, then to me it is a failure. I watched Reddit go from having high quality discussion in 2008-9 to devolving into the PC meme dumpster it is today [1]. HN still has the highest discussion quality of any "forum" I know of, but (1) it can sometimes randomly be very hostile/toxic to new tech, the most glaring example being crypto. (2) HN is basically a…

I built this because I wanted my own directory of public companies running bug bounty programs — where I could see their infrastructure in one place and have a real idea of where to start poking holes. Neobotnet collects intel data from companies on HackerOne and Bugcrowd — subdomains, DNS records, web servers with status codes, indexed/crawled URLs, JS files, and exposed secrets/paths (still building this last part). The data is already there when you need it. No scans to run. Currently tracking 41 companies, 63,878 web servers, and 1.8M+ URLs. Long term I want to expand this to…
